我正在尝试使用mkyoung教程学习RESTful Web服务。我试图执行我的第一个应用程序,但我得到“HTTP状态404.请求的资源不可用”错误。
以下是我的.java
文件内容:
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;
@Path("/message")
public class exeClass {
@GET
@Path("/{param}")
public Response printMessage(@PathParam("param") String msg) {
String result = "Restful example : " + msg;
return Response.status(200).entity(result).build();
}
}
我的web.xml
文件:
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >

<!-- Auto scan REST service -->

<param-value>true</param-value>
</context-param>
<!-- this need same with resteasy servlet url-pattern -->

<servlet-name>resteasy-servlet</servlet-name>
<servlet-class>

</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>resteasy-servlet</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
当我尝试输入&gt;&gt; http://localhost:8080/RestEasyExmp/rest/message/thank%20you
&lt;&lt;它给出了“请求的资源不可用”。错误
这是我的文件内容:
