HTTP状态404时，使用Jersey在Java中运行简单的RESTful Web服务 [英] HTTP Status 404 when running simple RESTful web service in Java using Jersey

问题描述

当使用Jersey在Java中运行简单的RESTful Web服务时，我正在获得 HTTP状态404 。我正在使用教程

解决方案

我所犯的错误是不指定服务名称（由 @Path 注释指定）。做完之后就行了。

所以本质上，点击的URL应该是 http：// localhost：8080 / com.kj.rest.jersey.first / rest / path_from_rest_class ，之前我错过了 path_from_rest_class 。

I am getting HTTP Status 404 when running simple RESTful web service in Java using Jersey. I am following the tutorial REST with Java (JAX-RS) using Jersey. I have copied all the jars that I downloaded from Jersey download site to WEB-INF/lib folder of my project(please see the screenshot for jars).

When I run the application from eclipse development environment Eclipse Console shows that Tomcat was started successfully. My web-app is deployed and I can see index.html coming up. But hitting http://localhost:8080/com.kj.rest.jersey.first/ gives Http Status 404.

My Environment:

• Spring Tool Suite as my eclipse dev environment
• Jersey 2.22.2 jars
• Apache Tomcat v8.0

Please note I am not using Maven in my project and I also looked at other similar questions here but none of them solved my issue.

What am I missing, where should I look for the issue, which logs?

解决方案

The mistake that I was making was to not specify the service name(specified by @Path annotation) in the URL. After doing that it worked.

So essentially the URL to hit should be http://localhost:8080/com.kj.rest.jersey.first/rest/path_from_rest_class and I missed the path_from_rest_class earlier.
