  • springmvc.xml和applicationContext.xml配置的特点

    1:springmvc.xml配置要点

    一般它主要配置Controller的组件扫描器和视图解析器

    下为:springmvc.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:p="http://www.springframework.org/schema/p" 
        xmlns:context="http://www.springframework.org/schema/context" 
        xmlns:mvc="http://www.springframework.org/schema/mvc" 
        xmlns:task="http://www.springframework.org/schema/task"
        xsi:schemaLocation="
            http://www.springframework.org/schema/beans 
            http://www.springframework.org/schema/beans/spring-beans-4.2.xsd 
            http://www.springframework.org/schema/context 
            http://www.springframework.org/schema/context/spring-context-4.2.xsd 
            http://www.springframework.org/schema/mvc 
            http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd 
            http://www.springframework.org/schema/task 
            http://www.springframework.org/schema/task/spring-task-4.2.xsd">    
            
            <!-- 使用注解开发,不用配置controller,需要配置一个组件扫描器 -->  
            <context:component-scan base-package="com.edu.test.controller"/>
            <!-- 视图解析器 -->                
            <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
                <!-- 配置从项目根目录到指定目录一端路径 ,建议指定浅一点的目录-->
                <property name="prefix" value="/WEB-INF/jsp/"></property>
                <!-- 文件的后缀名 -->
                <property name="suffix" value=".jsp"></property>
            </bean>
    </beans>

    2:applicationContext.xml配置要点(在web.xml文件需要加<listener>)

    下为:applicationContext.xml文件

    <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-4.2.xsd
            http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-4.2.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-4.2.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-4.2.xsd">
         <!-- 配置组件扫描器,使用注解方式开发,不用配置dao和service -->
    <!--
    在springmvc.xml文件中也可以配置这个属性 --> <context:component-scan base-package="com.edu.test"/> <!-- 数据源 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/test" /> <property name="username" value="root" /> <property name="password" value="" /> </bean> <!-- 配置session工厂 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="configLocation" value="classpath:mybatis-config.xml"/> </bean> <!-- 事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!-- 配置AOP通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <!-- 配置事务属性 --> <tx:attributes> <!-- 添加事务管理的方法 --> <tx:method name="save*" propagation="REQUIRED"/> <tx:method name="delete*" propagation="REQUIRED"/> <tx:method name="update*" propagation="REQUIRED"/> <tx:method name="select*" read-only="true"/> </tx:attributes> </tx:advice> <!-- 配置AOP,为添加事务管理的操作配置AOP --> <aop:config> <!-- 引入的Spring定义的事务通知,需要使用aop:advisor --> <!-- 下面难 --> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.edu.test.service.*.*(..))" /> </aop:config> </beans>

    3:在web.xml文件中,将springmvc.xml和applicationContext.xml一起引入

    下为:web.xm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"
        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">
        <!-- 配置监听器 -->
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </context-param>
        
        <!-- 中央控制器 -->
        <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:springmvc.xml</param-value>
            </init-param>
        </servlet>
        <servlet-mapping>
            <servlet-name>springmvc</servlet-name>
            <url-pattern>*.do</url-pattern>
        </servlet-mapping>
        
        
        <!-- 配置Spring提供的字符编码过滤器 -->
        <filter>
            <filter-name>SpringCharacterEncodingFilter</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>SpringCharacterEncodingFilter</filter-name>
            <url-pattern>*.do</url-pattern>
        </filter-mapping>
    </web-app>
