Spring Web MVC 的HandlerMapping的使用之-------SimpleUrlHandlerMapping(有三种配法)

使用背景:

第一步>>>

在包com.spring.web.controller下创建一个Controller: LoginConstroller

public class LoginController extends AbstractController{

public ModelAndView handleRequestInternal(HttpServletRequest request,

HttpServletResponse response)throws Exception{

String userName=request.getParameter("username");

String pwd=request.getParameter("pwd");

String msg="";

ModelAndView mav=new ModelAndView("loginResult"); //注意要在/WEB-INF/jsp下面创建loginResult.jsp页面

if(!userName.equals("liuxi")){

msg="用户名不存在!";

}else if(!pwd.equals("8888")){

msg="密码不正确!";

}else{

msg="恭喜您登录成功!";

}

mav.addObject("msg",msg);

return mav;

}

}

第二步>>>>

配置web.xml:

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5"

xmlns="http://java.sun.com/xml/ns/javaee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>

<servlet-name>sample</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>sample</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

</web-app>

第三步>>>>

配置sample-servlet.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"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="loginController" class="com.spring.web.controller.LoginController"/>

<bean id="handlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

<!-- 配置方法一

<property name="urlMap">

<map>

<entry key="/user/login.do" value-ref="loginController"/>

</map>

</property>

-->

<!-- 配置方法二

<property name="mappings">

<bean class="org.springframework.beans.factory.config.PropertiesFactoryBean">

<property name="location">

<value>urlMap.properties</value> <!-- 此时urlMap.properties文件应放在WebRoot目录下! -->

</property>

</bean>

</property>

-->

<!-- 配置方法三 -->

<property name="mappings">

<props>

<prop key="/user/login.do">loginController</prop>

</props>

</property>

</bean>

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix"><value>/WEB-INF/jsp/</value></property>

<property name="suffix"><value>.jsp</value></property>

<property name="viewClass">

<value>

org.springframework.web.servlet.view.JstlView

</value>

</property>

</bean>

</beans>
