1.首先以一个项目做例子，该项目用到的框架即为SpringMVC+mybatis,项目环境为MyEclipse+sqlserver+tomcat6，项目的地址（项目+数据库备份文件）大家可以上我的百度云下载http://pan.baidu.com/s/1o8qDqxs
2.还原项目怎么还原这里不具体说了，打开项目，找到ApplicationContext.xml,先改变一下数据库的连接，把用户名和密码设成自己的数据库的用户名和密码
3.我们现在整体看一下这个项目的结构，首先是整合SpringMVC,Appicationcontext-mvc.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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" 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"><!-- 启用spring mvc 注解--> <mvc:annotation-driven/> <!-- 自动扫描的包名 ，使Spring支持自动检测组件，如注解的Controller--> <context:component-scan base-package="com.flf.controller" /> <!--配置拦截器, 多个拦截器,顺序执行 --> <mvc:interceptors> <mvc:interceptor> <!-- 匹配的是url路径 --> <mvc:mapping path="/**/*.html*"/> <bean class="com.flf.interceptor.LoginHandlerInterceptor"/> </mvc:interceptor> <mvc:interceptor> <mvc:mapping path="/**/*.html*"/> <bean class="com.flf.interceptor.RightsHandlerInterceptor"/> </mvc:interceptor> </mvc:interceptors> <!-- 视图解析器:定义跳转的文件的前后缀 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/jsp/"/> <property name="suffix" value=".jsp"/><!--可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑 --> </bean> <bean id="exceptionResolver" class="com.flf.resolver.MyExceptionResolver"></bean></beans>
4.整合mybitas,ApplicationContext.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: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.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <import resource="ApplicationContext-service.xml"/> <!-- 配置数据源 ，与数据库的连接--> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"/> <property name="username" value="sa"/> <property name="password" value="123456"/> <property name="url" value="jdbc:sqlserver://localhost:1433; DatabaseName=chongqing"/> </bean> <!-- mybatis配置 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="configLocation" value="classpath:mybatis/config.xml"/> </bean> <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg index="0" ref="sqlSessionFactory"></constructor-arg> </bean> <!-- 扫描 basePackage下所有的接口，根据对应的mapper.xml为其生成代理类--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.flf.mapper" /> </bean> <!-- 数据源指向于DataSource --> <bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 增删该查的操作指向于transactionManager --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="delete*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception"/> <tx:method name="insert*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception" /> <tx:method name="update*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception" /> <tx:method name="save*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception" /> <tx:method name="*" propagation="REQUIRED" read-only="true"/> </tx:attributes> </tx:advice> <!-- aop: 作用表达于com.flf.service下的所有service，指向于txAdvice的方法 --> <aop:config> <aop:pointcut id="pc" expression="execution(* com.flf.service..*(..))" /> <aop:advisor pointcut-ref="pc" advice-ref="txAdvice" /> </aop:config></beans>
5web.xml整合SpringMVC和mybitas
<?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" 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>wl</display-name> <context-param> <param-name>webAppRootKey</param-name> <param-value>wl</param-value> </context-param> --> <!-- 初始化过程首先读的节点 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/ApplicationContext.xml</param-value> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.xml</param-value> </context-param> <!-- 配置字符集 --> <filter> <filter-name>encodingFilter</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> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>com.flf.listener.WebAppContextListener</listener-class> </listener> <!-- 初始化 DispatcherServlet时，该框架在 web应用程序classpath目录中寻找spring/ApplicationContext-mvc.xml的文件， 并在那里定义相关的Beans，重写在全局中定义的任何Beans --> <servlet> <servlet-name>springMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/ApplicationContext-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 所有以.html的请求，都会被DispatcherServlet处理 --> <servlet-mapping> <servlet-name>springMvc</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping></web-app>
6.当我们新增一个对象的时候，先要在Applicationcontext.service中注入该对象的service，然后再在mybatis文件夹中增加该对象对应的xml文件
