Question

我知道这个问题已多次重复，但我无法解决其他线程的问题，但我的问题仍然没有解决？

我使用的是eclipse-Spring和Tomcat Server

我的web.xml为：

    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>*.jsp</url-pattern>
    </servlet-mapping>
    <context-param>
      <param-name>applicationContext</param-name>
      <param-value>applicationContext.xml</param-value>
    </context-param>

我的dispatcher-servlet.xml为：

    <context:component-scan base-package="com.test.controller"></context:component-scan> 
    <mvc:annotation-driven />
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/jsp/"></property>
    <property name="suffix" value=".jsp"></property>
    </bean> </i>

applicationContext.xml as：

    <bean id="dataSourceBean" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
    <property name="url" value="jdbc:mysql://localhost/projectdemo"></property>
    <property name="username" value="root"></property>
    <property name="password" value="mysql"></property>        
    </bean> 
    <bean id="sessionFactoryBean" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSourceBean"></property>
    <property name="mappingResources">
        <value>com/test/pojo/User.hbm.xml</value>                   
    </property>
    <property name="hibernateProperties">
          <props>
              <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
              <prop key="hibernate.show_sql">true</prop>
          </props>
     </property>
    </bean>
    <bean id="hibernateTemplateBean" class="org.springframework.orm.hibernate3.HibernateTemplate">
    <property name="sessionFactory" ref="sessionFactoryBean"></property>
</bean>
     <bean id="authenticateServiceBean" class="com.test.service.AuthticateService">
    <property name="hibernateTemplate" ref="hibernateTemplateBean"></property>
    </bean>

我的LoginController为：

    @RequestMapping("/Login.jsp")
    public class LoginController {
    @Autowired 
 private AuthticateService authenticateService;
 //@RequestMapping(value ="WEB-INF/jsp/results.jsp",method = RequestMethod.POST)
 @RequestMapping(method = RequestMethod.POST)
 public ModelAndView processCredentials(@RequestParam("username")String username,@RequestParam("password")String password) {
     System.out.println ("in LoginController");
     String message = "Invalid credentials";
     if(authenticateService.verifyUserNameAndPassword(username, password)) {
         System.out.println ("after IFin LoginController");
         message = "Welcome " + username + "!!";
         System.out.println ("after IFin LoginControllermsg" +message);
     }

     ModelAndView msg = new ModelAndView();
     msg.setViewName("results");
     msg.addObject("message",message);
     System.out.println ("before return" +message);
     return msg;
    //return new ModelAndView("results","message",message);
    }
     }

results.jsp文件：

    <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01  Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>ProjectDemo</title>
    </head>
    <body>
    <h1><%= request.getAttribute("message") %></h1>
    </body>
    </html>

我在控制台中获得低于msg的信息：

    userobject
    User ID : 1, User name : admin, Password : admin123
    after IFin LoginController
    after IFin LoginControllermsgWelcome admin!!
    before returnWelcome admin!!
    Nov 23, 2012 11:19:08 AM org.springframework.web.servlet.DispatcherServlet   noHandlerFound
    WARNING: No mapping found for HTTP request with URI [/projectdemo/WEB- INF/jsp/results.jsp] in DispatcherServlet with name 'dispatcher'

我收到“http：// localhost：8080 / projectdemo / Login.jsp”

HTTP状态404 -

输入状态报告消息说明请求的资源（）不可用。

在控制台中，它从LoginController返回值并打印值并使用mysql数据库用户表值进行检查。

未显示“return msg”，它在控制台中显示为：

    Nov 23, 2012 11:19:08 AM org.springframework.web.servlet.DispatcherServlet noHandlerFound
    WARNING: No mapping found for HTTP request with URI [/projectdemo/WEB-INF/jsp/results.jsp] in DispatcherServlet with name 'dispatcher'

任何人都可以帮助我吗？已经超过两天了！!!!

你的“回复信息”

 ModelAndView msg = new ModelAndView();
 msg.setViewName("results");
 msg.addObject("message",message);
 System.out.println ("before return" +message);
 return msg;

不是消息！它是一个模型（关键“消息”：值消息）和一个视图（“结果”）视图是应呈现的jsp文件的名称。而且你没有这样的jsp文件（这就是警告No mapping found for HTTP request with URI [/projectdemo/WEB-INF/jsp/results.jsp]抱怨的）

您需要编写此jsp文件并将其存储在/WEB-INF/jsp/results.jsp！

中

警告：在DispatcherServlet中找不到带有URI [/projectdemo/WEB-INF/jsp/results.jsp]且名称为“dispatcher”的HTTP请求的映射

HTTP状态404 -
