服務

package com.lymedo; 

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

@Path("/service") 
public class Service { 

    @GET 
    @Path("/hello") 
    @Produces(MediaType.TEXT_PLAIN) 
    public String sayHello(){ 

     return "Hello!"; 

    } 

} 

我正在使用郵遞員測試以下URL的服務： http://localhost:8080/RestService/rest/service/hello

所以我假設這是一個映射問題，並且Tomcat找不到聲明該服務的類？

我希望這是明顯的東西。任何幫助將不勝感激。謝謝

您需要的不僅僅是jersey-server。您需要的主要是

<dependency> 
    <groupId>org.glassfish.jersey.containers</groupId> 
    <artifactId>jersey-container-servlet</artifactId> 
    <version>${jersey2.version}</version> 
</dependency>
