Running REST with Java(JAX-RS) with Jersey on IntelliJ / Tomcat
提问by Philip
I'm trying to do the following tutorial in IntelliJ on OSX:
我正在尝试在 OSX 上的 IntelliJ 中执行以下教程：
http://www.vogella.com/tutorials/REST/article.html
http://www.vogella.com/tutorials/REST/article.html
While running the code in Eclipse everything works fine. But running the code in IntelliJ delivers 404s for the same URI.
在 Eclipse 中运行代码时一切正常。但是在 IntelliJ 中运行代码会为相同的 URI 提供 404。
The program should run on a Apache Tomcat Server 8.0.20.
该程序应该在 Apache Tomcat Server 8.0.20 上运行。
I've done exactly what was written in the Tutorial but i can't figure out why it won't work in IntelliJ. I've searched for days now, finding a solution.
我已经完全完成了教程中写的内容，但我不明白为什么它在 IntelliJ 中不起作用。我已经搜索了几天，找到了解决方案。
It looks like something with the deployment is wrong, because the index.jsp is working fine.
看起来部署有问题，因为 index.jsp 工作正常。
Hope somebody can help me.
希望有人可以帮助我。

你好：

// Plain old Java Object it does not extend as class or implements
// an interface
// The class registers its methods for the HTTP GET request using the @GET annotation.
// Using the @Produces annotation, it defines that it can deliver several MIME types,
// text, XML and HTML.
// The browser requests per default the HTML MIME type.
//Sets the path to base URL + /hello
@Path("/hello")
public class Hello {
// This method is called if TEXT_PLAIN is request
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayPlainTextHello() {
return "Hello Jersey";
}
// This method is called if XML is request
@GET
@Produces(MediaType.TEXT_XML)
public String sayXMLHello() {
return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
}
// This method is called if HTML is request
