尝试拨打休息服务

Question

我试图调用我的rest，在url http://localhost:8080/ProvaMaven/rest/getuser 获取服务，但我总是找不到

这是我的 web.xml

这是我的班级

package com;

import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;

@Path("/rest")
public class Rest
{
    @GET
    @Path("/getuser")
    @Produces(MediaType.APPLICATION_JSON)
    public User getUser()
    {
        User u = new User();
        u.setName("carmine");
        u.setSurname("armenante");
        
        
        return u;
    }
}

我试图找出配置错误可能是什么，但什么也没有，我向我的 web 和 pom 文件添加了一些东西，但遗憾的是没有任何改进。我还清理并安装了我的 Maven 项目，但什么也没有

Answer 1

pom 中的工件名称是

ProbaMaven

。我假设这是可部署的 war 文件的实际名称，因此它应该是 URL 中的应用程序名称，而不是

TestMaven

。
