Maven + 最新SSM整合

. tophtml

1. 開發環境搭建

參考博文:Eclipse4.6(Neon) + Tomcat8 + MAVEN3.3.9 + SVN項目完整環境搭建java

2. Maven Web項目建立

2.1. new projectpython

2.2. new 2 mysql

2.3. new 3web

2.4. 4spring

2.5. 完成後目錄結構圖sql

 

dir

 

2.5 (可選)設置: 選中項目 單擊右鍵設置;數據庫

  • 項目編碼換成UTF-8:Properties -> Resource -> Text file encodingexpress

 

preperties resource

 

  • 設置默認的JRE:Properties -> Java Build Path -> 選項卡 Librariesapache

 

environment

 

  • 設置 Properties -> Project Facets

 

select

 

選中3.0 可能會出錯

 

error

 

解決方法: 修改該項目路徑下的 .settings/ org.eclipse.wst.common.project.facet.core.xml 文件;

<!-- 修改成須要的版本號 -->
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <fixed facet="wst.jsdt.web"/>
  <installed facet="java" version="1.8"/>
  <installed facet="jst.web" version="3.0"/>
  <installed facet="wst.jsdt.web" version="1.0"/>
</faceted-project>

重啓Eclipse可能會警告!按照提示操做便可。
或者參考網站: Cannot change version of project facet Dynamic web

3. SSM整合

2個配置文件:spring-mybatis.xml、spring-mvc.xml
2個資源文件:jdbc.propertis、log4j.properties

完整目錄結構以下圖:

3.1 Maven引入須要的JAR包

本教程使用部分jar包的版本:

Spring: 4.3.3.RELEASE
       Spring MVC:  4.3.2.RELEASE
       MyBatis:  3.4.1
       mybatis-spring:  1.3.0
       mysql-connector-java:  6.0.4
       javax.servlet-api:3.1.0 
       commons-dbcp:  1.4
       fastjson:  1.2.17
       commons-io:  2.5
       commons-codec:  1.10

推薦2個maven找jar包配置的網站:

3.2 Spring與MyBatis的整合

全部須要的JAR包都引入之後,首先進行Spring與MyBatis的整合,而後再進行JUnit測試,先看一個項目結構圖:

 

dir2

 

3.2.1 創建JDBC屬性文件(文件編碼修改成utf-8)

代碼清單 3-2:jdbc.properties

jdbc.driver_class=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql:///test?serverTimezone=UTC&characterEncoding=utf8&useUnicode=true&useSSL=false
jdbc.username=username
jdbc.password=password

#定義初始鏈接數
initialSize=0
#定義最大鏈接數
maxActive=20
#定義最大空閒
maxIdle=20
#定義最小空閒
minIdle=1
#定義最長等待時間
maxWait=60000
3.2.2 創建spring-mybatis.xml配置文件

這個文件就是用來完成spring和mybatis的整合的。這裏面也沒多少行配置,主要的就是自動掃描,自動注入,配置數據庫。註釋也很詳細,你們看看就明白了。

代碼清單 3-3:spring-mybatis.xml

<?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:mybatis-spring="http://mybatis.org/schema/mybatis-spring" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring-1.3.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">

    <!-- 支持註解 -->
    <context:annotation-config></context:annotation-config>
        <!--自動掃描 :經過註解過濾被掃描的類 -->  
        <context:component-scan base-package="org.sei" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Repository"/>
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Service"/>
    </context:component-scan>

    <!-- 引入配置文件 -->
    <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    </bean>

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="${jdbc.driver_class}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <!-- 初始化鏈接大小 -->
        <property name="initialSize" value="${initialSize}"></property>
        <!-- 鏈接池最大數量 -->
        <property name="maxActive" value="${maxActive}"></property>
        <!-- 鏈接池最大空閒 -->
        <property name="maxIdle" value="${maxIdle}"></property>
        <!-- 鏈接池最小空閒 -->
        <property name="minIdle" value="${minIdle}"></property>
        <!-- 獲取鏈接最大等待時間 -->
        <property name="maxWait" value="${maxWait}"></property>
    </bean>

    <!-- spring和MyBatis完美整合,不須要mybatis的配置映射文件 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!-- 自動掃描mapping.xml文件 -->
        <property name="mapperLocations" value="classpath*:org/sei/mapping/*.xml"></property>
    </bean>

    <!-- DAO接口所在包名,Spring會自動查找其下的類 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="org.sei.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>

    <!-- (事務管理)transaction manager, use JtaTransactionManager for global tx -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

</beans>
3.2.3 Log4j的配置

詳情參考博文:【轉】Log4j配置詳解;我這裏直接貼碼。

代碼清單 3-4:log4j.properties

#定義LOG輸出級別
log4j.rootLogger=INFO,Console,File
#定義日誌輸出目的地爲控制檯
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#能夠靈活地指定日誌輸出格式,下面一行是指定具體的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到達指定尺寸的時候產生一個新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定輸出目錄
log4j.appender.File.File = logs/ssm.log
#定義文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 輸出因此日誌,若是換成DEBUG表示輸出DEBUG以上級別日誌
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
3.2.4 JUnit測試Mybatise

通過以上步驟(到3.2.2,log4j不配也沒影響),咱們已經完成了Spring和mybatis的整合,這樣咱們就能夠編寫一段測試代碼來試試是否成功了。

3.2.4.1 建立測試用表

用SQL語句在test數據庫中創建一個測試表user_t

代碼清單 3-5:test_t.sql

DROP TABLE IF EXISTS `user_t`;

CREATE TABLE `user_t` ( `id` INT(11) NOT NULL AUTO_INCREMENT, `user_name` VARCHAR(40) NOT NULL, `password` VARCHAR(255) NOT NULL, `age` INT(4) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=INNODB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

/*Data for the table `user_t` */

INSERT INTO `user_t`(`id`,`user_name`,`password`,`age`) VALUES (1,'test1','pwd1',21);
INSERT INTO `user_t`(`id`,`user_name`,`password`,`age`) VALUES (2,'test2','pwd2',22);
INSERT INTO `user_t`(`id`,`user_name`,`password`,`age`) VALUES (3,'測試3','pwd2',23);
3.2.4.2 利用MyBatis Generator自動建立代碼

參考博文:使用MyBatis Generator自動建立代碼

這個可根據表自動建立實體類、MyBatis映射文件以及DAO接口;固然我習慣將生成的接口名改成 UserDao,而不是直接用它生成的UserMapper。若是不想麻煩能夠不改。完成後將文件複製到工程中。如圖:

 

generator

 

注意:

  • 自動生成的Dao和Pojo就只改包名,主要別忘記修改UserMapper.xml文件;

 

mapper

 

3.2.4.3 創建Service接口和實現類

目錄結構:

 

service dir

 

代碼清單 3-6:UserService.jave

package org.sei.service;

import org.sei.pojo.User;

public interface UserService {
   public User getUserById(int userId);
}

代碼清單 3-7:UserServiceImpl.jave

package org.sei.service.impl;

import javax.annotation.Resource;

import org.sei.dao.UserDao;
import org.sei.pojo.User;
import org.sei.service.UserService;
//import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service   //注意:此註解不寫會報錯
public class UserServiceImpl implements UserService {
   //@Autowired 和 @Resource
   //這裏二者均可以用;具體詳情請參考下面2個網站:
   //http://www.cnblogs.com/leiOOlei/p/3713779.html
   //http://www.zhihu.com/question/39356740
   @Resource
   private UserDao userDao;
   
   @Override
   public User getUserById(int userId) {
       return this.userDao.selectByPrimaryKey(userId);
   }
}
3.2.4.4 創建測試類

測試類在src/test/java中創建,下面測試類中_註釋掉的部分是不使用Spring時,通常狀況下的一種測試方法_;若是使用了Spring那麼就可使用註解的方式來引入配置文件和類,而後再將service接口對象注入,就能夠進行測試了。

若是測試成功,表示Spring和Mybatis已經整合成功了。輸出信息使用的是Log4j打印到控制檯。

代碼清單 3-8:TestMyBatis.jave

package org.sei.testmybatis;

import javax.annotation.Resource;

import org.apache.log4j.Logger;
//import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
//import org.springframework.context.ApplicationContext;
//import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.alibaba.fastjson.JSON;
import org.sei.pojo.User;
import org.sei.service.UserService;

@RunWith(SpringJUnit4ClassRunner.class)  //表示繼承了SpringJUnit4ClassRunner類
@ContextConfiguration(locations = {"classpath:spring-mybatis.xml"})

public class TestMyBatis {
    private static Logger logger = Logger.getLogger(TestMyBatis.class);
// private ApplicationContext ac = null;
    @Resource
    private UserService userService = null;

// @Before
// public void before() {
// ac = new ClassPathXmlApplicationContext("applicationContext.xml");
// userService = (IUserService) ac.getBean("userService");
// }

    @Test
    public void test1() {
        User user = userService.getUserById(2);
        // System.out.println(user.getUserName());
        // logger.info("值:"+user.getUserName());
        logger.info(JSON.toJSONString(user));
    }
}

注意: 我用的是MySQL Connector/J 6.x 新版驅動,直接報異常!!!

若有須要請看博文:MySQL Connector/J 6.x jdbc.properties 配置, mysql-connector-java-6.0.4.jar 異常

結果如圖:

 

result

 

至此,完成Spring和mybatis這兩大框架的整合,下面在繼續進行SpringMVC的整合。

3.3 整合SpringMVC

上面已經完成了2大框架的整合,SpringMVC的配置文件單獨放,而後在web.xml中配置整合。

3.3.1 配置spring-mvc.xml

配置裏面的註釋也很詳細,在此就不說了;主要是自動掃描控制器,視圖模式,註解的啓動這三個。

**注意:**配置文件中的一行:class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"

個人項目裏是jackson2.X版本的,若是你用的是jackson1.X版本的,不用寫"2"。

  </bean> 

</beans>
3.3.2 配置web.xml文件

這裏面對spring-mybatis.xml的引入以及配置的spring-mvc的Servlet就是爲了完成SSM整合,以前2框架整合不須要在此處進行任何配置。配置同樣有詳細註釋,很少解釋了。

代碼清單 3-10:web.xml

3.3.3 JUnit測試SpringMVC Controller

接下來測試一下,極可能失敗,不要緊,繼續調試;遇到問題是應該的,解決問題才能進步!
(我也在不停的和BUG做鬥爭啊...)

3.3.3.1 創建UserController控制類
3.3.3.2 創建MockTestController測試類
3.3.3.3 JUnit測試

詳情參考博文:springmvc controller junit 測試

總結

  • 包的導入

  • 註解的使用

  • MySQL Connector/J 6.x 的新變化

  • 複製到代碼的時候要根據本機環境修改相應的代碼
