spring-mvc基于xml的配置

配置web.xml

    <!--配置spring-MVC拦截-->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

spring配置文件：DispatcherServlet-servlet.xml

    <!-- 1. 配置处理器映射，springmvc默认的处理器映射器
             BeanNameUrlHandlerMapping:根据bean的name属性的url去找handlerController -->
    <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>

    <!--根据浏览器url匹配简单url的key，key就是Controller的id找到Controller-->
    <!--注：不常用-->

    <!--根据类名（MyController）类名.do来访问,类名首字母小写，测试得出如果类名中间出现大写会将后面截取掉-->
    <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>

    <!-- 2. 配置处理器适配置器执行Controller -->
    <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>

    <!--可以与上面的处理适配器共存，区别是实现HttpRequestHandler接口，接口没有返回值-->
    <bean class="org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter"></bean>


    <!-- 3.配置一个控制器 -->
    <bean name="/userController.do" class="com.royal.backoffice.web.controller.UserController"></bean>

    <!-- 4.配置springmvc视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>
