java - Spring MVC Web 服务 GET (Rest) 调用 : 404

Question

我正在尝试实现简单的网络服务，该服务采用 userId 并在 HTML 网页上显示一些用户评分信息。

我尝试使用 spring mvc 编写一些基于 spring 注解的 web 服务

当我尝试运行以下程序时，出现 404 错误。

http://localhost:8080/EdgeStore/execute/user1

这是我编写的简单程序。 我在这个程序中遗漏了什么吗？

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

<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:context="http://www.springframework.org/schema/context"
 xmlns:mvc="http://www.springframework.org/schema/mvc" 
 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-4.2.xsd
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context-4.2.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">

        <context:component-scan base-package="EdgeStore"/>

        <mvc:annotation-driven/>

    </beans>

调度员是

  <?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/j2ee"  
    xmlns:web="http://xmlns.jcp.org/xml/ns/javaee"   
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee  
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" id="WebApp_ID"  
    version="2.4">

   <display-name>EdgeStore</display-name>
     <servlet>
          <servlet-name>EdgeStore</servlet-name>
    <servlet-class>
          org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
   <load-on-startup>1</load-on-startup>
  </servlet>

   <servlet-mapping>
     <servlet-name>EdgeStore</servlet-name>
     <url-pattern>/</url-pattern>
 </servlet-mapping> 
</web-app>

Controller 是

package EdgeStore;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.ResponseStatus;

@Controller
@RequestMapping("/execute")
    public class executeController {

    @RequestMapping(value="/{userId}", method = RequestMethod.GET)
    @ResponseBody
    public UserProfile getUserProfile(@PathVariable("userId") String userId) {
        UserProfile userProfile = new UserProfile();
        userProfile.setUserId(userId);
        userProfile.setSegmentId("defaultSegement");
        return userProfile;
    }
}

你能以这种格式更改你的调度程序并尝试:

 <display-name>EdgeStore</display-name>
     <servlet>
          <servlet-name>EdgeStore</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
        <param-name>contextConfigLocation</param-name>
// Give location for your config file.
        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
    </init-param>
   <load-on-startup>1</load-on-startup>
  </servlet>

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

如果这不起作用，请告诉我。我会删除我的答案。
