整合步驟:

一、建立maven工程,添加全部目標依賴;
二、建立spring目錄,建立spring基礎配置;
三、整合mybatis、durid、flyway;
四、整合logback工具;
五、添加測試類,測試經過,第一階段完成;前端

1、建立soyann工程,添加項目依賴(IDEA)

一、建立一個新的工程soyann,添加business模塊,目錄結構以下;html5

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

2、建立spring配置項

clipboard.png

一、建立spring-applicationContest.xml,做爲spring配置的根文件。在添加其它模塊前,建立一個根配置,做爲各模塊的公共配置項;node

二、根配置的內容以下,後期隨着添加各個模塊,將會做相應的改動。mysql

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-4.1.xsd ">

    <!-- 配置要掃描的包 ,有多個能夠用';'號隔開,也可寫多個context:component-scan -->
    <context:component-scan base-package="com.soyann.business" />

    <!-- spring 啓用aop -->
    <aop:aspectj-autoproxy proxy-target-class="true" />
    <!-- 激活各類對於bean類的註解標註 -->
    <context:annotation-config />
</beans>

3、整合mybatis,druid,flyway工具

clipboard.png

一、druid是阿里巴巴的數據庫鏈接池。flyway爲數據庫版本管理工具。經過整合mybatis、druid及flyway,能夠實現數據庫查詢後將數據持久化。接下來按順序一個個文件添加進來。
二、添加spring-flyway.xml文件,配置以下:css3

<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
            http://www.springframework.org/schema/beans 
            http://www.springframework.org/schema/beans/spring-beans-4.0.xsd"
    default-lazy-init="false">

    <!-- flyway配置 -->
    <bean id="flyway" class="org.flywaydb.core.Flyway" init-method="migrate">
        <!-- 指向spring-mybatis.xml中的dataSource配置 -->
        <property name="dataSource" ref="dataSource" />
        <property name="encoding" value="UTF-8" />
        <property name="table" value="TB_SCHEMA_VERSION" />
        <property name="locations" value="db/migration" />
        <property name="baselineOnMigrate" value="true" />
        <property name="baselineVersion">
            <bean class="org.flywaydb.core.api.MigrationVersion"
                factory-method="fromVersion">
                <constructor-arg value="0" />
            </bean>
        </property>
    </bean>

</beans>

這裏須要注意的是,<property name="dataSource" ref="dataSource" />中描述的dataSource是指spring-mybatis.xml中描述的dataSource。<property name="locations" value="db/migration" />中,描述了你數據庫腳本的版本目錄,工具從db/migration這個目錄下讀取數據庫的腳本。git

三、添加jdbc.properties文件,配置以下:github

#數據庫驅動
jdbc.driver=com.mysql.jdbc.Driver
#數據庫鏈接url
jdbc.url=jdbc:mysql://127.0.0.1:3306/soyann?relaxAutoCommit=true&useUnicode=true&characterEncoding=UTF-8&characterSetResults=UTF-8&zeroDateTimeBehavior=convertToNull&autoReconnect=true&failOverReadOnly=false
#數據庫鏈接用戶名
jdbc.username=root
#數據庫鏈接密碼
jdbc.password=AXUE+dhMhCrtVF1usq8EB7bv4kBhkv6n81KtiG9HRnPEoQjWsPax84mMFAQONb3ireEifDcFFxdRnrZYomc3pA==
#配置數據庫密碼是否須要解密,這裏須要注意druid 1.0.16版本及以上的解密時須要同時配置publicKey,配置方式以下
druid.connectionProperties=config.decrypt=true;config.decrypt.key=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBALBt81XVN/W8vchTvUPwUD6NLk9LpwRRhY/+TQvkvM1hZIpzX1+SB1JLjcWcIwu4AkELau0pyjJ4LfC0LoOA/q0CAwEAAQ==
#配置初始化大小、最小、最大
druid.initialSize=10
#最小鏈接池數量
druid.minIdle=10
#最大鏈接池數量
druid.maxActive=50
#獲取鏈接時最大等待時間,單位毫秒
druid.maxWait=5000
#配置間隔多久才進行一次檢測,檢測須要關閉的空閒鏈接,單位是毫秒,有兩個含義:1) Destroy線程會檢測鏈接的間隔時間,若是鏈接空閒時間大於等於minEvictableIdleTimeMillis則關閉物理鏈接;2) testWhileIdle的判斷依據
druid.timeBetweenEvictionRunsMillis=60000
#配置一個鏈接在池中最小生存的時間,單位是毫秒
druid.minEvictableIdleTimeMillis=300000
#驗證語句
druid.validationQuery=SELECT 'x'
#檢測鏈接是否有效的超時時間,單位:秒。底層調用jdbc Statement對象的void setQueryTimeout(int seconds)方法
druid.validationQueryTimeout=5
#申請鏈接時執行validationQuery檢測鏈接是否有效,作了這個配置會下降性能
druid.testOnBorrow=false
#歸還鏈接時執行validationQuery檢測鏈接是否有效,作了這個配置會下降性能
druid.testOnReturn=false
#建議配置爲true,不影響性能,而且保證安全性。申請鏈接的時候檢測,若是空閒時間大於timeBetweenEvictionRunsMillis,執行validationQuery檢測鏈接是否有效
druid.testWhileIdle=true
#打開PSCache,而且指定每一個鏈接上PSCache的大小,若是用Oracle,則把poolPreparedStatements配置爲true,mysql能夠配置爲false。分庫分表較多的數據庫,建議配置爲false
druid.poolPreparedStatements=false
druid.maxPoolPreparedStatementPerConnectionSize=100
#按期把監控數據輸出到日誌中
druid.timeBetweenLogStatsMillis=300000
#配置監控統計攔截的filters
druid.filters=config,stat,slf4j
#使用全局監控
druid.useGlobalDataSourceStat=true
#對於長時間不使用的鏈接強制關閉,禁用此配置,設置爲false
druid.removeAbandoned=false
#超過30分鐘開始關閉空閒鏈接
druid.removeAbandonedTimeout=1800
#將當前關閉動做記錄到日誌
druid.logAbandoned=true

這裏採用了數據庫鏈接密碼加密功能,怎樣生成鏈接加密下面再分解。

四、添加實體文件。在Resource根目錄下,添加generatorConfig.xml配置,自動生成實體文件,內容以下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
    <!--數據庫驅動jar -->
    <!-- <classPathEntry location="D:\mysql-connector-java-5.1.39.jar" /> -->

    <!-- MyBatis3 - The "by example" methods in these generated objects support virtually unlimited dynamic where clauses.
        MyBatis3Simple -The mappers generated with this target runtime are very basic CRUD operations only with no "by example" methods and very little dynamic SQL -->
    <context id="soyann" targetRuntime="MyBatis3">

        <property name="javaFileEncoding" value="UTF-8"/>

        <!--生成註釋 -->
        <commentGenerator>
            <property name="suppressAllComments" value="false"/>
            <property name="suppressDate" value="false"/>
            <property name="addRemarkComments" value="true"/>
        </commentGenerator>

        <!--
        <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver"
            connectionURL="jdbc:oracle:thin:@遠程ip地址或localhost:1521:orcl" userId="用戶名"
            password="密碼">
                              針對oracle數據庫
            <property name="remarksReporting" value="true"></property>
        </jdbcConnection>
         -->


        <!--數據庫鏈接 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/soyann"
                        userId="root" password="123456">
            <!-- 針對mysql數據庫 -->
            <property name="useInformationSchema" value="true"></property>
        </jdbcConnection>
        <!--默認false Java type resolver will always use java.math.BigDecimal if
            the database column is of type DECIMAL or NUMERIC. -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!--生成實體類 指定包名 以及生成的地址 (能夠自定義地址,可是路徑不存在不會自動建立 使用Maven生成在target目錄下,會自動建立) -->
        <javaModelGenerator targetPackage="com.soyann.general.model"
                            targetProject="MAVEN">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!-- 生成的SQL映射文件包名和位置,這裏配置將生成的SQL映射文件放在com.soyann.general.mapper這個包下 -->
        <sqlMapGenerator targetPackage="com.soyann.general.mapper"
                         targetProject="MAVEN">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!--生成Dao文件 能夠配置 type="XMLMAPPER"生成xml的dao實現 context id="DB2Tables" 修改targetRuntime="MyBatis3" -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.soyann.general.dao" targetProject="MAVEN">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!--要生成那些表(更改tableName和domainObjectName就能夠),對應數據庫表 mysql能夠加入主鍵自增 字段命名 忽略某字段等 -->
        <table tableName="tb_user" domainObjectName="UserEntity" enableCountByExample="false"
               enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false"/>

    </context>

</generatorConfiguration>
        <!-- mybatis-generator:generate 執行命令-->

接下來在idea中添加啓動命令:

添加此配置的做用是自動生成數據表實體跟mapper文件,無須手寫容易出錯。運行命令,將生成的實體文件添加到對應目錄下:

五、添加spring-mybatis.xml文件

    <!-- propagation:事物傳播行爲
             一、REQUIRED(默認值):在有transaction狀態下執行;如當前沒有transaction,則建立新的transaction
             二、SUPPORTS:如當前有transaction,則在transaction狀態下執行;若是當前沒有transaction,在無transaction狀態下執行
             三、MANDATORY:必須在有transaction狀態下執行,若是當前沒有transaction,則拋出異常IllegalTransactionStateException
             四、REQUIRES_NEW:建立新的transaction並執行;若是當前已有transaction,則將當前transaction掛起
             五、NOT_SUPPORTED:在無transaction狀態下執行;若是當前已有transaction,則將當前transaction掛起
             六、NEVER:在無transaction狀態下執行;若是當前已有transaction,則拋出異常IllegalTransactionStateException
             七、NESTED 若是當前存在事務,則在嵌套事務內執行。若是當前沒有事務,則執行與 REQUIRED 相似的操做
         read-only:讀寫或只讀事務,默認false(讀寫)
         isolation:可選的事務隔離級別設置
             一、DEFAULT: 這是一個PlatfromTransactionManager默認的隔離級別,使用數據庫默認的事務隔離級別.另外四個與JDBC的隔離級別相對應
             二、READ_COMMITTED: 保證一個事務修改的數據提交後才能被另一個事務讀取。另一個事務不能讀取該事務未提交的數據
             三、READ_UNCOMMITTED: 這是事務最低的隔離級別,它充許令外一個事務能夠看到這個事務未提交的數據
             四、REPEATABLE_READ: 這種事務隔離級別能夠防止髒讀,不可重複讀。可是可能出現幻像讀
             五、SERIALIZABLE 這是花費最高代價可是最可靠的事務隔離級別。事務被處理爲順序執行。除了防止髒讀,不可重複讀外,還避免了幻像讀
         rollback-for:致使事務回滾的異常類數組,Class對象數組,必須繼承自Throwable,通常咱們都繼承RuntimeException
         timeout:事務超時時間設置 -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">

    <aop:config expose-proxy="true" proxy-target-class="true">

            </list>
        </property>
    </bean>

</beans>

添加文件後,發現還有點問題,spring-flyway.xml及spring-mybatis.xml不能相互調用,且往下。

六、更新spring-applicationContext.xml文件,引用spring-flyway.xml、spring-mybatis.xml、jdbc.properties配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-4.1.xsd ">

    <!-- 配置要掃描的包 ,有多個能夠用';'號隔開,也可寫多個context:component-scan -->
    <context:component-scan base-package="com.soyann.business.*.mapper" />
    <context:component-scan base-package="com.soyann.business.*.service" />

    <!-- spring 啓用aop -->
    <aop:aspectj-autoproxy proxy-target-class="true" />
    <!-- 激活各類對於bean類的註解標註 -->
    <context:annotation-config />

    <!-- 引入屬性文件:方式二 -->
    <bean id="configProperties" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
        <property name="ignoreResourceNotFound" value="true" />
        <property name="locations">
            <list>
                <value>classpath:jdbc.properties</value>
                <!--<value>classpath:redis.properties</value>
                <value>classpath:webside.properties</value>-->
            </list>
        </property>
    </bean>

    <!-- 引入模塊配置文件 -->
    <import resource="spring-mybatis.xml" />
    <import resource="spring-flyway.xml" />
</beans>

七、添加web.xml文件,配置數據庫鏈接池等內容:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">
    <!-- RequestContextListener -->
    <listener>
        <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
    </listener>

    <!-- 指定Web根目錄 -->
    <context-param>
        <param-name>webAppRootKey</param-name>
        <param-value>Business.root</param-value>
    </context-param>


    <!-- 阿里巴巴druid鏈接池 啓用 Web 監控統計功能    start-->
    <filter>
        <filter-name>DruidWebStatFilter</filter-name>
        <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class>
        <init-param>
            <param-name>exclusions</param-name>
            <param-value>*. js ,*. gif ,*. jpg ,*. png ,*. css ,*. ico ,/ druid /*</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>DruidWebStatFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <servlet>
        <servlet-name>DruidStatView</servlet-name>
        <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>DruidStatView</servlet-name>
        <url-pattern>/druid/*</url-pattern>
    </servlet-mapping>
    <!-- 鏈接池 啓用 Web 監控統計功能 end-->


</web-app>

八、在IDEA工具中引入spring及web文件

4、整合logback工具

一、在resource目錄下添加logback.xml,內容以下;

<?xml version="1.0" encoding="UTF-8"?>
<!-- 從高到地低 OFF 、 FATAL 、 ERROR 、 WARN 、 INFO 、 DEBUG 、 TRACE 、 ALL -->
<!-- 日誌輸出規則  根據當前ROOT 級別,日誌輸出時,級別高於root默認的級別時  會輸出 -->
<!-- 如下  每一個配置的 filter 是過濾掉輸出文件裏面,會出現高級別文件,依然出現低級別的日誌信息,經過filter 過濾只記錄本級別的日誌-->

<!--屬性描述 scan:性設置爲true時,配置文件若是發生改變,將會被從新加載,默認值爲true scanPeriod:設置監測配置文件是否有修改的時間間隔。-->
<!--若是沒有給出時間單位,默認單位是毫秒。當scan爲true時,此屬性生效。默認的時間間隔爲1分鐘。-->
<!--debug:當此屬性設置爲true時,將打印出logback內部日誌信息,實時查看logback運行狀態。默認值爲false。-->
<configuration scan="true" scanPeriod="60 seconds" debug="false">
    <statusListener class="ch.qos.logback.core.status.OnConsoleStatusListener"/>
    <!--定義日誌文件輸入位置-->
    <property name="FILE_DIR" value="/logs"/>
    <property name="FILE_NAME" value="soyann"/>
    <!-- 日誌最大的歷史 30天 -->
    <property name="maxHistory" value="30"/>

    <!-- Console 控制檯級別輸出日誌 -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!-- encoder 默認配置爲PatternLayoutEncoder  對日誌進行格式化-->

            <!-- 可選節點,控制保留的歸檔文件的最大數量,超出數量就刪除舊文件假設設置每月滾動,且<maxHistory>是6,

            <maxHistory>${maxHistory}</maxHistory>
        </rollingPolicy>

        <!-- 按照固定窗口模式生成日誌文件,當文件大於20MB時,生成新的日誌文件。窗口大小是1到3,當保存了3個歸檔文件後,將覆蓋最先的日誌。

            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
        </encoder>

    </logger>

    <logger name="com.soyann" level="DEBUG" additivity="false">
        <appender-ref ref="ASYNC"/>
    </logger>

    <logger name="dao" level="DEBUG" additivity="false">

        <appender-ref ref="INFOAPPENDER"/>
    </logger>

    <!-- 全部的日誌級別:OFF、FATAL、ERROR、WARN、INFO、DEBUG、ALL ,建議只使用四個級別,優先級從高到低分別是 ERROR、WARN、INFO、DEBUG-->

    <!-- root級別   DEBUG -->
    <root level="DEBUG">
        <!-- 控制檯輸出 -->
        <appender-ref ref="STDOUT" />
        <!-- 文件輸出 -->
        <appender-ref ref="ERROR" />
        <appender-ref ref="INFO" />
        <appender-ref ref="WARN" />
        <appender-ref ref="DEBUG" />
        <appender-ref ref="TRACE" />
    </root>
</configuration>

二、web.xml中註冊logback:

<!--logback日誌配置 start-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/spring-applicationContext.xml</param-value>
    </context-param>
    <context-param>
        <param-name>logbackConfigLocation</param-name>
        <param-value>classpath:logback.xml</param-value>
    </context-param>
    <listener>
        <listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class>
    </listener>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!--logback日誌配置 end-->

到這裏,spring+mybatis框架整合基本完成,下面就來測試下這個框架吧。

5、框架測試

一、resource/db/migration添加數據庫腳本;這裏我用了別人建立好的,再也不貼代碼;
二、在service目錄下添加一個接口及實現類,代碼以下:

clipboard.png

IUserService.java

package com.soyann.business.user.service;

import com.soyann.business.user.model.UserEntity;

import java.util.List;

/**
 * @ProjectName: soyann
 * @FileName: com.soyann.business.user.service
 * @Description: (do what)
 * @Copyright: Copyright(C) 2016-2017 All rights Reserved
 * @Company: ShenZhen Information Technology Co.,LTD.
 * @Author: dell657 neil
 * @Version V1.0
 * @Date: 2017/10/28
 * <p>
 * Modification  History:
 * Date         Author        Version        Discription
 * -----------------------------------------------------------------------------------

 * Why & What is modified: <修改緣由描述>
 */
public interface IUserService {
    UserEntity getUserById(int userId);
    List<UserEntity> getAllUser();
}

UserServiceImpl.java

package com.soyann.business.user.service.impl;

import com.soyann.business.user.mapper.UserMapper;
import com.soyann.business.user.model.UserEntity;
import com.soyann.business.user.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;

/**

 * @FileName: com.soyann.business.user.service.impl

 * -----------------------------------------------------------------------------------
 * 2017/10/28     neil          1.0             1.0

 */
@Service("userService")
public class UserServiceImpl implements IUserService {
    @Autowired(required=false)
    private UserMapper userMapper;

    @Override
    public UserEntity getUserById(int userId) {
        return userMapper.selectByPrimaryKey(userId);
    }

    @Override
    public List<UserEntity> getAllUser() {
        return userMapper.getAllUser();
    }
}

三、在test目錄下添加測試類TestMyBatis.java,代碼以下:

package com.soyann.business.mybatis;

import com.alibaba.fastjson.JSON;
import com.soyann.business.user.model.UserEntity;
import com.soyann.business.user.service.IUserService;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.mock.web.MockHttpServletResponse;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.annotation.Resource;
import java.io.IOException;
import java.util.List;


/**
 * @ProjectName: soyann
 * @FileName: com.soyann.business.mybatis
 * @Description: (do what)
 * @Copyright: Copyright(C) 2016-2017 All rights Reserved
 * @Company: ShenZhen Information Technology Co.,LTD.
 * @Author: neil
 * @Version V1.0
 * @Date: 2017/10/28
 * <p>
 * Modification  History:
 * Date         Author        Version        Discription
 * -----------------------------------------------------------------------------------
 * 2017/10/28     neil          1.0             1.0
 * Why & What is modified: <修改緣由描述>
 */
//表示繼承了SpringJUnit4ClassRunner類
/*@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring/spring-applicationContext.xml"})*/
public class TestMyBatis {
    private static Logger logger = LoggerFactory.getLogger(TestMyBatis.class);
    @Resource
    private IUserService userService = null;

    @Before
    public void before() {
        //使用"spring.xml"和"spring-mybatis.xml"這兩個配置文件建立Spring上下文
        ApplicationContext ac = new ClassPathXmlApplicationContext(new String[]{"spring/spring-applicationContext.xml", "spring/spring-mybatis.xml"});
        //從Spring容器中根據bean的id取出咱們要使用的userService對象
        userService = (IUserService) ac.getBean("userService");
    }

    @Test
    public void test1() {
        logger.info("任務開始執行...");
        UserEntity userEntity = userService.getUserById(4);
        // System.out.println(user.getUserName());
        // logger.info("值:"+user.getUserName());
        //System.out.println(JSON.toJSONString(userEntity));
        logger.info(JSON.toJSONString(userEntity));
        logger.info("任務執行結束");
        logger.error("任務執行結束");
        logger.debug("任務執行結束");
    }
}

添加代碼後,執行代碼,查看控制檯輸出結果。
