Question

我是JAX-RS的新手，我创建了一个Maven项目但是当我尝试调用我的服务时，我在Tomcat上获得了以下服务器状态

HTTP状态404：源服务器未找到当前目标资源的代表或不愿意披露那个存在。

的pom.xml

</web-app>

服务

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Postman使用以下URL测试服务： http://localhost:8080/RestService/rest/service/hello

所以我假设这是一个映射问题而且Tomcat找不到声明服务的类？

我希望这是显而易见的事情。任何帮助将不胜感激。感谢

您需要的不仅仅是jersey-server。你需要的主要是

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

JAX-RS Jersey Maven HTTP状态404原始服务器未找到目标资源的当前表示
