Question

我有一个新的Java Jax-rs入门maven项目，可以从中创建一个war文件。当我尝试使用tomcat服务器启动它时，其显示的HTTP状态404 –未找到所有路由。遇到此问题的任何人都请帮助我，

我在Eclipse ID中遵循的步骤 1.创建一个新项目 2.选择其他 3.选择一个向导，Maven-> Maven Project 4.使用默认工作位置，请按下一步 5.原型我选择了 jersey-quickstart-webapp

然后创建项目。配置好tomcat服务器后，便能够在该tomcat服务器上运行该应用程序，但是对于所有路由，甚至是默认路由，它都会显示 找不到404页面

添加我的文件

MyResource.java

package com.testing.restapi;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

/**
 * Root resource (exposed at "myresource" path)
 */
@Path("myresource")
public class MyResource {

    /**
     * Method handling HTTP GET requests. The returned object will be sent
     * to the client as "text/plain" media type.
     *
     * @return String that will be returned as a text/plain response.
     */
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String getIt() {
        return "chal gaya madarchod";
    }
}
