标签: java web-services rest maven restful-url

我正在学习使用jax RS(jersey)实现的Restful webservices。我使用jersery快速启动Web应用程序创建了一个示例maven项目。 代码:

的index.jsp

<html>
<body>
<h2>Jersey RESTful Web Application!</h2>
<p><a href="webapi/myresource">Jersey resource</a>
<p>Visit <a href="http://jersey.java.net">Project Jersey website</a>
for more information on Jersey!

MyResource.java

 package org.restful.sumanth.RestfulSumanth;

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

/**
 * Root resource (exposed at "myresource" path)
 */
@Path("myresource")
public class MyResource {

/**
 * Method handling HTTP GET requests. The returned object will be sent
 * to the client as "text/plain" media type.
 *
 * @return String that will be returned as a text/plain response.
 */
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getIt() {
    return "Got it!";
}
}

WEB.XML

<?xml version="1.0" encoding="UTF-8"?>
<!-- This web.xml file is not required when using Servlet 3.0 container,
     see implementation details http://jersey.java.net/nonav/documentation    /latest/jax-rs.html -->

</servlet>
<servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/webapi/*</url-pattern>
</servlet-mapping>

当我运行项目时,我有输出:

Jersey RESTful Web Application!

[Jersey resource][1]

Visit [Project Jersey website][2] for more information on Jersey! 


  [1]: http://webapi/myresource
  [2]: https://jersey.java.net/

当我点击Jersey资源链接时,即使我有资源,它也会给予404。有人可以解释为什么myresource在被要求时无法找到?

我从另一个stackoverflow帖子得到了答案:404 error with Jersey REST Service on Tomcat

我已经取代了下面的依赖项,它使它工作: 的
