Jersey REST Web Service，Tomcat，Eclipse和404 [英] Jersey REST Web Service, Tomcat, Eclipse and 404's
问题描述
我已阅读了许多帖子，但似乎无法解决我的问题。你也会看到与这个帖子非常相似的帖子，甚至是同一个教程。甚至跟随他们，我似乎无法得到答案。
I've read through a number of posts, but just can't seem to solve my problem. You'll also see tons of posts very similar to this one, even the same tutorial. Even following them, I can't seem to get to the answer.
本质上，我试图按照简单的教程： http://www.vogella.com/articles/REST/
Essentially, I'm trying to follow the simple tutorial at: http://www.vogella.com/articles/REST/
我有做了一些修改，使其与Jersey 2.x兼容
I've made a few changes to make it compatible with Jersey 2.x
我正在使用：
Eclipse
Tomcat 6（部署/运行在内Eclipse）
jaxrs-ri-2.0
我已经在Eclipse中启用了JAX-RS Facet
I'm using: Eclipse Tomcat 6 (Deployed/Run as within Eclipse) jaxrs-ri-2.0 I've enabled the JAX-RS Facet in Eclipse
一切都构建好
Tomcat启动在Eclipse
内可以通过以下方式获取静态页面内容：
Everything builds fine Tomcat starts fine within Eclipse I can get to a static page content via:
http：// localhost：8080 / RestTEST2 / index。 html
但是，当我尝试通过以下方式访问我的服务时：
However, when I try to access my service via:
http：// localhost：8080 / RestTEST2 / jaxrs / hello
我收到一个404，没有找到和请求的资源（未找到）不可用。
I receive a 404 with "message not found" and "The requested resource (Not Found) is not available."
这是我的web.xml位于/ WebCo ntent / WEB-INF / web.xml
Here is my web.xml which is located at /WebContent/WEB-INF/web.xml

这是我的Java类：
package TestREST;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
// 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
@GET
@Produces(MediaType.TEXT_HTML)
public String sayHtmlHello() {
return "<html> " + "<title>" + "Hello Jersey" + "</title>"
+ "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
}
}
我还配置了一个JAX-RS用户库，引用它包括所有JAX-RS jar。
I also have a JAX-RS User Library configured and referenced that includes all the JAX-RS jars.
想知道什么会导致Web服务找不到？
Thoughts on what would cause the web service to not be found?
推荐答案
Jersey 2.0无法识别名称为的com.un.jersey.config.property.packages （web。 XML）。尝试将其更改为 jersey.config.server.provider.packages ，如ServerProperties.PROVIDER_PACKAGES 。
Jersey 2.0 does not recognize init-param with name com.sun.jersey.config.property.packages (web.xml). Try to change it to jersey.config.server.provider.packages as described in ServerProperties.PROVIDER_PACKAGES.
