錯誤404：未找到錯誤，顯示Jeresy靜態服務

Question

我創建了Web動態項目，上下文名稱為“ restJeresy”。 並在本地使用Websphere自由服務器。

當我點擊url http：// localhost：9080 / restJeresy / TestRestService / callService以下錯誤顯示

Error 404: Not Found 

誰能幫我我所缺少的嗎？

這是我的代碼，

package com.demo;

import javax.ws.rs.GET;
import javax.ws.rs.Path;

@Path("/TestRestService")
public class HelloWorldService {

     @Path("/callService")
     @GET
    public String getMsg() {
        return "Hello World !! - Jersey 2";
    }
}

Answer 1

web.xml中的servlet映射問題。請檢查

 <?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>restJeresy</display-name>

      <servlet>
          <servlet-name>Jersey RESTful Application</servlet-name>
          <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
               <init-param>
                <param-name>jersey.config.server.provider.packages</param-name>
                <param-value>com.demo</param-value>
            </init-param>
             <load-on-startup>1</load-on-startup>
          </servlet>    
<servlet-mapping>    
<servlet-name>Jersey RESTful Application</servlet-name>
          <url-pattern>/restf/*</url-pattern>    
</servlet-mapping>   
</web-app>

然后嘗試訪問http：// localhost：9080 / restJersey / restf / TestRestService / callService
