Spring MVC整合MyBatis

1.需要的jar包



根据自己需求添加具体版本和所需的jar包。

2.在web.xml添加以下配置

<?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"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">

<context-param>

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

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

</context-param>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<servlet>

<servlet-name>action</servlet-name>

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

<init-param>

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

<param-value>classpath:springmvc-servlet.xml</param-value>

</init-param>

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

</servlet>

<servlet-mapping>

<servlet-name>action</servlet-name>

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

</servlet-mapping>

</web-app>

3.在beans.xml添加以下配置

<?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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
<!-- 1.配置扫描包service,dao -->

<context:component-scan base-package="com.cName.pName.dao,com.cName.pName.service" />

<!-- 2.配置属性文件jdbc.properties -->

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

<!-- 3.配置数据源dataSource -->

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

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

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

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

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

</bean>

<!-- 4.配置SqlSessionFactory 整合mybatis，自动扫描mapper文件 -->

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

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

<property name="configLocation" value="classpath:sqlMapConfig.xml" />

<property name="mapperLocations" value="classpath:com/cName/pName/mapper/*.xml" />

</bean>

<!-- 5.配置事务 -->

<bean id="txManager"

class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

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

</bean>

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

<tx:attributes>

<tx:method name="insert*" propagation="REQUIRED" />

<tx:method name="update*" propagation="REQUIRED" />

<tx:method name="delete*" propagation="REQUIRED" />

<tx:method name="find*" read-only="true" />

<tx:method name="get*" read-only="true" />

<tx:method name="view*" read-only="true" />

</tx:attributes>

</tx:advice>

<aop:config>

<aop:pointcut expression="execution(* com.cName.pName.service.*.*(..))"

id="txPointCut" />

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

</aop:config>

</beans>

4.在springmvc-servlet.xml添加以下配置

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

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-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">

<!-- 1.配置扫描包controller -->

<context:component-scan base-package="com.cName.pName.controller" />

<!-- 2.配置内部资源视图解析器 -->

<bean id="jspViweResolver"

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix" value="/pages" />

<property name="suffix" value=".jsp" />

</bean>

<bean id="mappingJacksonHttpMessageConverter"

class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">

<property name="supportedMediaTypes">

<list>

<value>text/html;charset=UTF-8</value>

</list>

</property>

</bean>

<bean

class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

<property name="messageConverters">

<list>

<ref bean="mappingJacksonHttpMessageConverter" />

</list>

</property>

</bean>

</beans>

5.在sqlMapConfig.xml添加以下配置

<?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></configuration>

6.jdbc.properties内容为

jdbc.driverClassName=oracle.jdbc.driver.OracleDriver

jdbc.url=jdbc:oracle:thin:@127.0.0.1:1521:dbName

jdbc.username=username

jdbc.password=password

c3p0.pool.maxPoolSize=20
