public class TestexResourceConfig extends ResourceConfig { 
    public TestexResourceConfig() { 
     super(); 
     registerClasses(TestexService.class); 
    } 
} 

我的服务如下：我一直在使用下面给出@ApplicationPath资源配置中配置的服务

package com.testex.service; 

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

import com.testex.config.Config; 
import com.testex.config.ConfigLoader; 
import com.testex.provider.ProjectDetailsProvider; 
import com.testex.provider.VersionsProvider; 
import com.testex.provider.bean.Project; 
import com.google.gson.Gson; 

@Path("/rest") 
public class TestexService { 
    private final Config config; 

    public TestexService() { 
     super(); 
     config = ConfigLoader.getConfig(); 
    } 

    @GET 
    @Path("getDefaultProjectId") 
    @Produces(MediaType.APPLICATION_JSON) 
    public Response getDefaultProjectId() { 
     return Response.status(200).entity(new Gson().toJson(new Project(String.valueOf(config.getProjectId())))) 
       .build(); 
    } 

    @GET 
    @Path("getProjectDetails") 
    @Produces(MediaType.APPLICATION_JSON) 
    public Response getProjectDetails(@QueryParam("projectId") int projectId) { 
     return Response.status(200).entity(new Gson().toJson(new ProjectDetailsProvider().getProjectDetails(projectId))) 
       .build(); 
    } 

    @GET 
    @Path("getProjectVersionDetails") 
    @Produces(MediaType.APPLICATION_JSON) 
    public Response getProjectVersionDetails(@QueryParam("projectId") int projectId) { 
     return Response.status(200).entity(new Gson().toJson(new VersionsProvider().getVersionsForProject(projectId))) 
       .build(); 
    } 
} 

在上下文根 “TESTEX” 它部署到Tomcat 8，我打了以下网址：

http://localhost:8080/testex/resources/rest/getDefaultProjectId 

但我得到一个404 Not Found错误。请帮忙。

嗯，我想通了。我所需要做的就是将下面的依赖关系添加到我的pom中，并且所有作品都像魅力一样：

<dependency> 
     <groupId>org.glassfish.jersey.containers</groupId> 
     <artifactId>jersey-container-servlet</artifactId> 
     <version>2.22.2</version> 
    </dependency>
