404没有发现错误在弹簧mvc应用程序实现瓷砖

Question

我读了几篇关于这个404错误的文章，但无济于事。当我访问这个基地址为http://localhost:8080/chatapplication的项目时，我得到了404错误。我尝试使用url http://localhost:8080/chatapplication/chat也得到了同样的结果。我的代码如下： -

的web.xml

<!DOCTYPE web-app PUBLIC 
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
"http://java.sun.com/dtd/web-app_2_3.dtd" >

    </context-param> 

    <listener> 
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 

</web-app> 

调度-servlet.xml中

<beans xmlns="http://www.springframework.org/schema/beans"

    </bean> 
    <bean id="tilesConfigurer"

      <list> 
       <value>/WEB-INF/tiles.xml</value> 
      </list> 
     </property> 
    </bean> 

    </beans> 

tiles.xml

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

     <put-attribute name="body" value="/WEB-INF/jsp/chat.jsp" /> 
    </definition> 
    </tiles-definitions> 

Controller类如下： -

package com.abhishek.controllers; 

import org.springframework.web.bind.annotation.RequestMapping; 

/** 
* Created by CAN14 on 6/21/2016. 
*/ 
public class HelloWorldController { 
    @RequestMapping(value="/chat") 
    public String index() 
    { 
     System.out.println("**************"); 
     return "home"; 
    } 
} 

个

提前请help..thanks ..

Answer 1

缺少HelloWorldController类@Controller注解。

Answer 2

为您指定瓷砖视图解析器因此，您可以定义其他视图解析器，以便在您从控制器返回未映射的任何视图时使用。您的控制器中的 您将返回“主页”。其中没有映射到tiles.xml中。 将其更改为“聊天”，您将看到chat.jsp带有页眉和页脚，因为它被映射到tiles.xml中。

<bean id="viewResolver" 
      class="org.springframework.web.servlet.view.UrlBasedViewResolver"> 
     <property name="viewClass"> 
      <value> 
       org.springframework.web.servlet.view.tiles3.TilesView 
      </value> 
     </property> 
     <property name="order" value="0" /> 
    </bean> 

您还应该添加下面没有瓦片地图只有一个JSP

<bean id="jspViewResolver" 
     class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <property name="prefix"> 
     <value>/WEB-INF/views/</value> 
    </property> 
    <property name="suffix"> 
     <value>.jsp</value> 
    </property> 

    <property name="order" value="1"/> 
</bean>
