<!–主程序对应的配置文件–>
<!–开启bean注解扫描–>
<context:component-scan base-package=”com.XXX.service”/>
<!–加载properties文件–>
<context:property-placeholder location=”classpath*:jdbc.properties”/>
<!–数据源–>
<bean id=”dataSource” class=”com.alibaba.druid.pool.DruidDataSource”>
<property name=”driverClassName” value=”${jdbc.driver}”/>
<property name=”url” value=”${jdbc.url}”/>
<property name=”username” value=”${jdbc.username}”/>
<property name=”password” value=”${jdbc.password}”/>
</bean>
<!–整合mybatis到spring中–>
<bean class=”org.mybatis.spring.SqlSessionFactoryBean”>

</bean>
<!–映射扫描–>
<bean class=”org.mybatis.spring.mapper.MapperScannerConfigurer”>
<property name=”basePackage” value=”com.itheima.dao”/>
</bean>
<!–开启注解式事务–>
<tx:annotation-driven transaction-manager=”txManager”/>
<!–事务管理器–>
<bean id=”txManager” class=”org.springframework.jdbc.datasource.DataSourceTransactionManager”>
<property name=”dataSource” ref=”dataSource”/>
</bean>
</beans>
SpringMVC环境配置
- 注解的扫描
- 处理器适配器和处理器映射器
- 释放静态资源
<?xml version=”1.0″ encoding=”UTF-8″?>
<beans xmlns=”http://www.springframework.org/schema/beans”
xmlns:context=”http://www.springframework.org/schema/context”
xmlns:mvc=”http://www.springframework.org/schema/mvc”
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.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd”>
<mvc:annotation-driven/>
<context:component-scan base-package=”com.xxxx.controller”/>
<mvc:default-servlet-handler/>
</beans>
注意: <mvc:default-servlet-handler/>这个释放静态资源路不配置也是可以的 在web.xml中可以拦截*.do的请求是一样的效果
web.xml文件配置（1+1+1）
<?xml version=”1.0″ encoding=”UTF-8″?>
<web-app xmlns=”http://xmlns.jcp.org/xml/ns/javaee”
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=”http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd”
version=”3.1″>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext.xml</param-value>
</context-param>
<!–启动服务器时，通过监听器加载spring运行环境–>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<filter>
<filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring-mvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>(这里就可以写*.do那么就不需要配置释放静态资源了)
</servlet-mapping>
</web-app>
到此再写dao service controller 层就可以了 访问数据库测试一下就完成了ssm的基础搭建
