Spring+springmvc+Mybatis整合案例 xml配置版（myeclipse）详细版

Spring+springmvc+Mybatis整合案例

Version：xml版(myeclipse)

文档结构图：

从底层开始做起：

01.配置web.xml文件

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">

<display-name></display-name>

<!-- 配置spring装载bean的设置 -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationcontext.xml</param-value>

</context-param>

<!-- 配置编码 -->

<filter>

<filter-name>CharacterEncoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>utf-8</param-value>

</init-param>

<init-param>

<param-name>forceEncoding</param-name>

<param-value>true</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>CharacterEncoding</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<servlet>

<servlet-name>springmvc</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<!-- 配置springmvc需要的组件设置  -->

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext.xml</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>springmvc</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

</web-app>

02.配置applicationcontext.xml文件

<?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:aop="http://www.springframework.org/schema/aop"

xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"

xmlns:tx="http://www.springframework.org/schema/tx"

xsi:schemaLocation="

           http://www.springframework.org/schema/context

         http://www.springframework.org/schema/context/spring-context-4.2.xsd  ">

<!--01. 包扫描器 -->

<context:component-scan base-package="cn.zym.controller"></context:component-scan>

<!-- 02.数据源 -->

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

<property name="driverClass" value="${jdbc.driverClass}"></property>

<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>

<property name="user" value="${jdbc.user}"></property>

<property name="password" value="${jdbc.password}"></property>

</bean>

<!-- 1.1 关联jdbc.properties -->

<context:property-placeholder location="classpath:jdbc.properties"/>

<!-- 02.配置SessionFactory -->

<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="configLocation" value="classpath:mybatis-config.xml"></property>

<property name="dataSource" ref="dataSource"></property>

</bean>

<!--03. dao -->

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

<property name="sqlSessionFactoryBeanName" value="sessionFactory"></property>

<property name="basePackage" value="cn.zym.dao"></property>

</bean>

<!--04. service -->

<bean id="userservice" class="cn.zym.service.impl.UserServiceImpl">

<property name="dao" ref="IUserDao"></property>

</bean>

<!--05. controller -->

<bean id="/usercontroller.do" class="cn.zym.controller.UserController">

<property name="service" ref="userservice"></property>

</bean>

<!-- 06.配置事务管理器 -->

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<property name="dataSource" ref="dataSource"></property>

</bean>

<!-- 07.配置开启事务操作 -->

<tx:advice id="txAdvice" transaction-manager="transactionManager">

<tx:attributes>

<!--指定在连接方法上应用的事务属性 -->

<tx:method name="save*" isolation="DEFAULT" propagation="REQUIRED"/>

</tx:attributes>

</tx:advice>

<!-- aop配置 -->

<aop:config>

<aop:pointcut expression="execution(* *..service.*.*(..))" id="stockPointcut"/>

<aop:advisor advice-ref="txAdvice" pointcut-ref="stockPointcut"/>

</aop:config>

</beans>

一般使用Mybatis时不建议使用注解（会降低程序效率和增加开发难度）：这里依然还是选择原生的配置；

02.1jdbc.properties文件的书写

jdbc.driverClass=com.mysql.jdbc.Driver

jdbc.jdbcUrl=jdbc\:mysql\://localhost\:3306/zhangyiming

jdbc.user=zym

jdbc.password=admin

03.mybatis-config.xml的配置：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE configuration

PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>

<typeAliases>

这里将pojo包下的类设置了别名（在XXXdao.xml中直接调用该包下的类名即可）

<package name="cn.zym.pojo"/>

</typeAliases>

。。。。添加其他配置文件

</configuration>

Dao层书写：

Ok，这里需要添加对应dao的Mybatis操作文件，该文件通过spring容器生成了代理类，在上面有提到；

<!--03. dao -->   该代理类肯能会有多个，每个代理类的名称的生成规则：

Interface：IUserDao    proxy：IUserDao

Interface：UserDao    proxy：userDao

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

<property name="sqlSessionFactoryBeanName" value="sessionFactory"></property>

<property name="basePackage" value="cn.zym.dao"></property>

</bean>

Ok，配置dao对应的文件

04.IUserDao.xml 的配置

这里的xml文件一定要放置在与该接口同目录下（如果不设置具体描述文件路径的话；）

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE mapper

PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="cn.zym.dao.IUserDao">

<select id="save" parameterType="User">

insert into user (name,password) values (#{name},#{password})

</select>

</mapper>

Ok，接下来是注解配置Controller:

05.Controller的配置

public class UserController implements Controller{

private IUserService service;

public ModelAndView handleRequest(HttpServletRequest request,

HttpServletResponse response) throws Exception {

request.setCharacterEncoding("utf-8");

String name = request.getParameter("uname");

String password = request.getParameter("upassword");

System.out.println(name);

User user = new User();

user.setName(name);

user.setPassword(password);

service.save(user);

return new ModelAndView("/welcome.jsp");

}

public IUserService getService() {

return service;

}

public void setService(IUserService service) {

this.service = service;

}

}

这样在前台直接请求携带数据的时候将会触发该Handler，将数据报错到DB中

Useradd.jsp;

<body>

<form action="adduser.do" method="post">

<input type="text" name="name"/><br/>

<input type="text" name="password"/><br/>

<input type="submit" value="submit"/>

</form>

</body>
