126        </resources>
127   </build>
128 </project>

pom.xml

2.二、建立整合目錄

Mybatis：存放mybatis配置文件數據庫

Spring：存放spring以及整合文件apache

Resource：數據庫鏈接以及log4配置信息

2.三、建立MyBatis配置文件

建立mybatis-config.xml文件位於mybatis目錄下

mybatis-config.xml

1 <?xml version="1.0" encoding="UTF-8" ?>
2 <!DOCTYPE configuration
3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
4 "http://mybatis.org/dtd/mybatis-3-config.dtd">
5 <configuration>
6 </configuration>

該文件主要存mybatis配置。(該配置文件能夠不建立)

2.四、建立數據庫配置信息

建立db.properties文件位於resource文件夾下

db.properties

1 #數據庫鏈接驅動
2 jdbc.driver=com.mysql.jdbc.Driver
3 #數據庫鏈接url
4 jdbc.url=jdbc:mysql://localhost:3306/woo0nise?characterEncoding=utf-8
5 #數據庫用戶名
6 jdbc.username=root
7 #數據庫密碼
8 jdbc.password=root

該配置文件主要存放數據庫的配置,也能夠存放mybatis配置文件的屬性。

2.五、Spring整合mybatis

建立applicationContext-dao.xml文件位於spring文件夾下

applicationContext-dao.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4 xmlns:aop="http://www.springframework.org/schema/aop"
 5 xmlns:context="http://www.springframework.org/schema/context"
 6 xmlns:jdbc="http://www.springframework.org/schema/jdbc"
 7 xmlns:p="http://www.springframework.org/schema/p"
 8 xmlns:tx="http://www.springframework.org/schema/tx"
 9 xmlns:util="http://www.springframework.org/schema/util"
10 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
11 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
12 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
13 http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.1.xsd
14 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
15 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.1.xsd">
16 <!-- 加載數據庫配置文件 -->
17 <context:property-placeholder location="classpath:resource/db.properties" />
18 <!-- 配置數據源 -->
19 <!-- 數據庫鏈接池 -->
20 <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
21 destroy-method="close">
22 <property name="url" value="${jdbc.url}" />
23 <property name="username" value="${jdbc.username}" />
24 <property name="password" value="${jdbc.password}" />
25 <property name="driverClassName" value="${jdbc.driver}" />
26 <property name="maxActive" value="10" />
27 <property name="minIdle" value="5" />
28 </bean>
29 <!-- 配置SqlSessionFactory  -->
30 <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"  >
31 <!-- 配置數據源 -->
32 <property name="dataSource" ref="dataSource" ></property>
33 <!-- 配置MyBatis路徑 -->
34 <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" ></property>
35 </bean>
36 <!-- Mapper文件掃描器 -->
37 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" >
38 <property name="basePackage" value="com.test.dao" ></property>
39 </bean>
40 </beans>

applicationContext-dao.xml

該配置文件主要是spring整合mybatis文件。

2.六、Spring事務管理

建立applicationContext-trans.xml位於spring文件夾下

applicationContext-trans.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4 xmlns:context="http://www.springframework.org/schema/context"
 5 xmlns:jdbc="http://www.springframework.org/schema/jdbc"
 6 xmlns:p="http://www.springframework.org/schema/p"
 7 xmlns:tx="http://www.springframework.org/schema/tx"
 8 xmlns:util="http://www.springframework.org/schema/util"
 9 xmlns:aop="http://www.springframework.org/schema/aop"
10 xsi:schemaLocation="http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.1.xsd
11 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
12 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
13 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
14 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
15 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.1.xsd">
16 <!-- 配置事務管理器 -->
17 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
18 <!-- 配置數據源 -->
19 <property name="dataSource" ref="dataSource" ></property>
20 </bean>
21 <!-- 配置事務 -->
22 <tx:advice id="txAdvice" transaction-manager="transactionManager">
23 <tx:attributes>
24 <tx:method name="save*" propagation="REQUIRED" />
25 <tx:method name="insert*" propagation="REQUIRED" />
26 <tx:method name="add*" propagation="REQUIRED" />
27 <tx:method name="create*" propagation="REQUIRED" />
28 <tx:method name="delete*" propagation="REQUIRED" />
29 <tx:method name="update*" propagation="REQUIRED" />
30 <tx:method name="find*" propagation="SUPPORTS" read-only="true" />
31 <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
32 <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
33 </tx:attributes>
34 </tx:advice>
35 <!-- 切面 -->
36 <aop:config>
37 <aop:advisor advice-ref="txAdvice"
38 pointcut="execution(* com.taotao.service.impl.*.*(..))" />
39 </aop:config>
40 </beans>

applicationContext-trans.xml

該配置文件主要配置事務以及事務管理和切面(AOP)配置。

2.七、Spring掃描Service的實現類

建立applicationContext-service.xml位於spring文件夾下

applicationContext-service.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4 xmlns:aop="http://www.springframework.org/schema/aop"
 5 xmlns:context="http://www.springframework.org/schema/context"
 6 xmlns:jdbc="http://www.springframework.org/schema/jdbc"
 7 xmlns:p="http://www.springframework.org/schema/p"
 8 xmlns:tx="http://www.springframework.org/schema/tx"
 9 xmlns:util="http://www.springframework.org/schema/util"
10 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
11 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
12 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
13 http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.1.xsd
14 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
15 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.1.xsd">
16 <context:component-scan base-package="com.test.service"></context:component-scan>
17 </beans>

applicationContext-service.xml

該配置文件主要是用來掃描Service的實現類。

2.八、建立springmvc.xml

建立springmvc.xml文件位於spring文件夾下

springmvc.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4 xmlns:context="http://www.springframework.org/schema/context"
 5 xmlns:p="http://www.springframework.org/schema/p"
 6 xmlns:tx="http://www.springframework.org/schema/tx"
 7 xmlns:util="http://www.springframework.org/schema/util"
 8 xmlns:mvc="http://www.springframework.org/schema/mvc"
 9 xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd
10 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
11 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
12 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
13 http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.1.xsd">
14 <context:component-scan base-package="com.test.controller"></context:component-scan>
15 <!-- 配置視圖解析器 -->
16 <mvc:annotation-driven />
17 <bean
18 class="org.springframework.web.servlet.view.InternalResourceViewResolver">
19 <property name="prefix" value="/WEB-INF/jsp/" />
20 <property name="suffix" value=".jsp" />
21 </bean>
22 </beans>

2.九、配置web.xml

修改web.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app version="3.0" 
 3 xmlns="http://java.sun.com/xml/ns/javaee" 
 4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 5 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
 6 http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
 7 <display-name>taotao-manager</display-name>
 8 <welcome-file-list>
 9 <welcome-file>index.jsp</welcome-file>
10 </welcome-file-list>
11 <!-- 加載spring容器 -->
12 <context-param>
13 <param-name>contextConfigLocation</param-name>
14 <param-value>classpath:spring/applicationContext-*.xml</param-value>
15 </context-param>
16 <listener>
17 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
18 </listener>
19 <!-- 解決post亂碼 -->
20 <filter>
21 <filter-name>CharacterEncodingFilter</filter-name>
22 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
23 <init-param>
24 <param-name>encoding</param-name>
25 <param-value>utf-8</param-value>
26 </init-param>
27 <!-- <init-param>
28 <param-name>forceEncoding</param-name>

30 </init-param> -->
31 </filter>
32 <filter-mapping>
33 <filter-name>CharacterEncodingFilter</filter-name>
34 <url-pattern>/*</url-pattern>
35 </filter-mapping>
36 <!-- springmvc的前端控制器 -->
37 <servlet>
38 <servlet-name>dispatcherServlet</servlet-name>
39 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
40 <!-- contextConfigLocation不是必須的， 若是不配置contextConfigLocation， springmvc的配置文件默認在：WEB-INF/servlet的name+"-servlet.xml" -->
41 <init-param>
42 <param-name>contextConfigLocation</param-name>
43 <param-value>classpath:spring/springmvc.xml</param-value>
44 </init-param>
45 <load-on-startup>1</load-on-startup>
46 </servlet>
47 <servlet-mapping>
48 <servlet-name>dispatcherServlet</servlet-name>
49 <url-pattern>/</url-pattern>
50 </servlet-mapping>
51 </web-app>

web.xml

三、測試整合

3.一、建立實體類以及dao層

一、導入mybatis逆向工程

建立com.test.dao和com.test.entity包用於存放生成的文件

二、修改generatorConfig.xml文件

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE generatorConfiguration
 3   PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
 4   "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
 5  
 6 <generatorConfiguration>
 7 <context id="testTables" targetRuntime="MyBatis3">
 8 <commentGenerator>
 9 <!-- 是否去除自動生成的註釋 true：是 ： false:否 -->
10 <property name="suppressAllComments" value="true" />
11 </commentGenerator>
12 <!--數據庫鏈接的信息：驅動類、鏈接地址、用戶名、密碼 -->
13 <jdbcConnection driverClass="com.mysql.jdbc.Driver"
14 connectionURL="jdbc:mysql://localhost:3306/woo0nise" userId="root"
15 password="root">
16 </jdbcConnection>
17 <!-- 默認false，把JDBC DECIMAL 和 NUMERIC 類型解析爲 Integer，爲 true時把JDBC DECIMAL 和 
18 NUMERIC 類型解析爲java.math.BigDecimal -->
19 <javaTypeResolver>
20 <property name="forceBigDecimals" value="false" />
21 </javaTypeResolver>
22  
23 <!-- targetProject:生成PO類的位置 -->
24 <javaModelGenerator targetPackage="com.test.entity"
25 targetProject=".\src">
26 <!-- enableSubPackages:是否讓schema做爲包的後綴 -->
27 <property name="enableSubPackages" value="false" />
28 <!-- 從數據庫返回的值被清理先後的空格 -->
29 <property name="trimStrings" value="true" />
30 </javaModelGenerator>
31         <!-- targetProject:mapper映射文件生成的位置 -->
32 <sqlMapGenerator targetPackage="com.test.dao" 
33 targetProject=".\src">
34 <!-- enableSubPackages:是否讓schema做爲包的後綴 -->
35 <property name="enableSubPackages" value="false" />
36 </sqlMapGenerator>
37 <!-- targetPackage：mapper接口生成的位置 -->
38 <javaClientGenerator type="XMLMAPPER"
39 targetPackage="com.test.dao" 
40 targetProject=".\src">
41 <!-- enableSubPackages:是否讓schema做爲包的後綴 -->
42 <property name="enableSubPackages" value="false" />
43 </javaClientGenerator>
44 <!-- 指定數據庫表 -->
45 <table schema="" tableName="user"></table>
46 </context>
47 </generatorConfiguration>

generatorConfig.xml

三、運行GeneratorSqlmap生成實體文件以及mapper文件

四、將com.test.dao以及com.tes.entity到本工程中

3.二、建立業務邏輯層

一、建立com.test.service包用於存放業務邏輯層接口類

建立UserService接口文件

 1 package com.test.service;
 2  
 3 import com.test.entity.User;
 4  
 5 /**
 6  * <p>Title:UserService</p>
 7  * <p>Description:</p>
 8  * <p>Company:www.hack-gov.com</p>
 9  * @author 0nise
10  * @date 2017年1月1日 上午12:47:42
11  * @Email woo0nise@gmail.com
12  * @version 1.0
13  */
14 public interface UserService {
15 /**
16  * 新增用戶
17  * @author 0nise
18  * @date 2017年1月1日 上午12:48:12
19  * @Email woo0nise@gmail.com
20  * @param user
21  */
22 public int add(User user);
23 }

二、建立com.testservice.impl包用於存放業務邏輯層接口的實現類

建立UserServiceImpl類用於實現UserService接口文件

 1 package com.test.service.impl;
 2  
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.stereotype.Service;
 5  
 6 import com.test.dao.UserMapper;
 7 import com.test.entity.User;
 8 import com.test.service.UserService;
 9 /**
10  * <p>Title:UserServiceImpl</p>
11  * <p>Description:</p>
12  * <p>Company:www.hack-gov.com</p>
13  * @author 0nise
14  * @date 2017年1月1日 上午12:51:34
15  * @Email woo0nise@gmail.com
16  * @version 1.0
17  */
18 @Service
19 public class UserServiceImpl implements UserService {
20 //注入UserMapper
21 @Autowired
22 private UserMapper userMapper;
23  
24 @Override
25 public int add(User user) {
26 try {
27 userMapper.insert(user);
28 return 1;
29 } catch (Exception e) {
30 e.printStackTrace();
31 return -1;
32 }
33 }
34 }

3.三、建立Controller層

3.3.一、建立com.test.controller包用戶存放controller

建立UserController

 1 package com.test.controller;
 2  
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.stereotype.Controller;
 5 import org.springframework.web.bind.annotation.RequestMapping;
 6 import com.test.entity.User;
 7 import com.test.service.UserService;
 8  
 9 /**
10  * <p>Title:UserController</p>
11  * <p>Description:</p>
12  * <p>Company:www.hack-gov.com</p>
13  * @author 0nise
14  * @date 2017年1月1日 上午12:55:57
15  * @Email woo0nise@gmail.com
16  * @version 1.0
17  */
18 @Controller
19 public class UserController {
20 //注入UserService
21 @Autowired
22 private UserService userService;
23 @RequestMapping("ok")
24 public String add(){
25 User user = new User();
26 user.setUsername("admin99");
27 user.setUserpwd("admin99");
28 int i = userService.add(user);
29 if(i > 0){
30 System.out.println("ok");
31 }else{
32 System.err.println("error");
33 }
34 return null;
35 }
36 }
