Question

我正在尝试在wildfly上实现一个java JSON webservice并且悲惨地失败......

好的，这就是我现在所拥有的：

我的web.xml：

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>ReportBuilderBack</display-name>  
</web-app>

我的configapp.java：

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("/rest")
public class ConfigApp extends Application {
    //intentionally left blank

}

我的POJO课程：

import java.util.List;

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

import org.test.reportbuilderback.dao.UserDao;
import org.test.reportbuilderback.models.User;

@Path("/userwebservice")
public class UserWebService {

    @Path("/users")
    @GET
    @Produces("application/json")
    public Response listUsers(){
        List<User>allUsers=new UserDao().getAllUsers();
        return Response.status(200).entity(allUsers).build();               
    }

}

这一切都没有错误地部署到Wildfly 10.x. 但是，当转到http://localhost:8080/org.test.reportbuilderback/rest/userwebservice/users时，我只得到404。

我无法理解我在这里做错了什么。能不能就我做错了什么给出一些指示？

谢谢！

编辑：根据请求，添加了服务器日志输出。

19:43:57,775 INFO  [org.jboss.resteasy.resteasy_jaxrs.i18n] (ServerService Thread Pool -- 61) RESTEASY002225: Deploying javax.ws.rs.core.Application: class org.test.reportback.webservices.ConfigApp

在日志中，网络上下文为：/org.test.reportbuilderback-0.0.1-SNAPSHOT
你应该在你的网址中使用它：

 http://localhost:8080/org.test.reportbuilderback-0.0.1-SNAPSHOT/rest/userwebservice/users

或

 http://localhost:8080/org.test.reportbuilderback-0.0.1-SNAPSHOT/userwebservice/users

如果您的休息api因任何原因忽略@ApplicationPath("/rest")。

尝试用Java实现一个简单的JSON Web服务
