关于Spring、SpringMVC、Mybatis框架的整合
1.首先在工程中建立一个Dynamic Web 或者Maven工程
2.引入相关的jar包
2.1一共是3个配置文件：SpringContext.xml、Springmvc.xml、SqlMapConfig.xml
3.配置applicationContext.xml文件：
3.1一开始配置相应的schema检测（这里可以根据自己情况增加，并不是说就这些）
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
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
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
3.2配置jdbc属性文件：
<!--载入jdbc配置文件 --> <context:property-placeholder location="classpath:jdbc.properties" />
3.3封装数据源：
<bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<property name="driverClassName" value="${jdbc.driver}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
这里的数据池我用了阿里的Druid
3.4配置SqlSessionFactory:
<!-- 配置SqlSessionFactory -->
<bean class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 设置MyBatis核心配置文件 -->
<property name="configLocation" value="classpath:SqlMapConfig.xml" />
<!-- 设置数据源 -->
<property name="dataSource" ref="dataSource" />
<!--别名包扫描 -->
<property name="typeAliasesPackage" value="com.wzu.crm.pojo"></property>
</bean>
这其中的Mybatis全局配置文件我取名是“SqlMapConfig.xml”
3.5Mapper包的扫描：
<!-- 配置Mapper扫描 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 设置Mapper扫描包 -->
<property name="basePackage" value="com.wzu.crm.mapper" />
</bean>
3.6Service包的扫描：
<context:component-scan base-package="com.wzu.crm.service"></context:component-scan>
3.7有关事务的部分：配置事务管理器：
<!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 数据源 -->
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 通知 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<!-- 传播行为 -->
<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="add*" propagation="REQUIRED" />
<tx:method name="create*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
<tx:method name="select*" propagation="SUPPORTS" read-only="true" />
<tx:method name="get*" propagation="SUPPORTS" read-only="true" />
<tx:method name="query*" propagation="SUPPORTS" read-only="true" />
</tx:attributes>
</tx:advice>
3.8 配置AOP切面：
<aop:config>
<aop:advisor advice-ref="txAdvice"
pointcut="execution(* com.wzu.crm.service.*.*(..))" />
</aop:config>
4.到这里的话完整的Spring配置文件已经配好，接下来是SpringMvc.xml
4.1:SpringMvc内容较少：
<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!-- 配置Controller扫描 -->
<context:component-scan base-package="com.wzu.crm.controller" />
<!-- 属性文件配置加载-->
<context:property-placeholder location="classpath:crm.properties"/>
<!-- 配置注解驱动 -->
<mvc:annotation-driven></mvc:annotation-driven>
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<!-- 后缀 -->
<property name="suffix" value=".jsp" />
</bean>
</beans>
5.Mybatis的全局配置文件SqlMapConfig.xml:
<?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.还需要在WEB.xml中配置相关内容：
<!--引进applicationContext.xml文件-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 配置Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 编码过滤器 -->
<filter>
<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置Spring MVC servlet -->
<servlet>
<servlet-name>CRM</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CRM</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
配置到这里就已经完成了：只需要改动配置文件中的包名就行！然后按照正常的开发步骤做下去即可：Pojo——Mapper——Service——Serviceimpl——Controller
PS：在开发过程中applicationContext.xml可能会变得很多，你也可以按照功能的区别将其拆分成：1.applicationContext-dao.xml 2.applicationContext-service.xml 3.applicationContext-tran.xml
