Question

我使用Jersey 2.0 REST API创建了一个Web应用程序。它在我的本地计算机上工作得很好但是当我在AWS上部署我的应用程序时，RESTFul服务没有被调用。

以下是情景：

以下服务网址在我的本地计算机上运行正常。我的应用的上下文路径是/ testrest。

http://localhost:8080/testrest/test/rest

在AWS（Tomcat 8 Java 8）上部署时，下面的代码不起作用，并且给出了404错误：

http://testrest.wm5zqpd6m2.ap-southeast-1.elasticbeanstalk.com/testrest/rest/test

但有趣的是，如果我删除了testrest这个词，并点击下面的url就会返回成功的回复。 Plz尝试点击链接并查看结果。我附加了我的pom.xml，web.xml和我的资源类。

http://testrest.wm5zqpd6m2.ap-southeast-1.elasticbeanstalk.com/rest/test

的pom.xml

资源类：

package com.testing;

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

@Path("/")
public class TestRest {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("/test")
    public Response testRest(){

        return Response.ok("Success Again and Again", MediaType.APPLICATION_JSON).build();
    }

}

休息服务在本地而不是在aws上调用
