Spring MVC的控制器映射不起作用(Spring MVC Controller mapping

我工作的弹簧MVC项目。多次尝试后，我无法在地图控制器在春天。其结果是，404没有找到下面的URL总是返回。

HTTP：//本地主机：8080 / EcommerceBookStore / REST /欢迎

这是在web.xml

 <?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"> <display-name>EcommerceBookStore</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/applicationContext.xml, /WEB-INF/Ecommerce-servlet.xml </param-value> </context-param> <servlet> <servlet-name>Ecommerce</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Ecommerce</servlet-name> <url-pattern>/rest/</url-pattern> </servlet-mapping> <!-- <servlet> <servlet-name>Ecommerce</servlet-name> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> <init-param> <param-name>com.java.Client</param-name> <param-value>com.java.Client</param-value> </init-param> <init-param> <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name> <param-value>true</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>--> </web-app>

这里是控制器的HelloWorld

    package com.webspider.Controller;


    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;

   /*
    * author: Crunchify.com
    * 
    */

@Controller
public class HelloWorld {

    @RequestMapping("/welcome")
    public ModelAndView helloWorld() {

        String message = "<br><div style='text-align:center;'>"
                + "<h3>********** Hello World, Spring MVC Tutorial</h3>This message is coming from CrunchifyHelloWorld.java **********</div><br><br>";
        return new ModelAndView("welcome", "message", message);
    }
}

我没有看到在Tomcat中产出的任何错误。我希望类似的东西出现

INFO：映射URL路径[/欢迎]到处理器的HelloWorld。

我不知道什么是错的。任何人都可以请指出我错过了什么？

提前致谢。

Answer 1:

我想你已经在这里混合：

如果你的项目名称是休息，而你对rest.war部署它，那么你就不需要在web.xml这一行

<url-pattern>/rest/</url-pattern>

将其更改为

<url-pattern>/</url-pattern>

但是，如果你是ROOT.war运行它，你想在URL /休息，那么你必须如下操作：

@Controller
@RequestMapping("/rest")
public class HelloWorld {

本地主机：然后用下面的URL访问8080 //休息/欢迎

Answer 2:

试试以下，

@RequestMapping("/welcome", method = RequestMethod.GET)
public ModelAndView helloWorld() {...

确保您的映射，

<servlet-mapping>
    <servlet-name>Ecommerce</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

自定义您的默认servlet名，

 <mvc:default-servlet-handler default-servlet-name="Ecommerce"/>

URL尝试：本地主机：8080 /电子商务/欢迎
