使用Restful与JBOSS运行时出错

时间：2016-05-06 14:12:39

标签： java eclipse rest maven jboss

我创建了一个maven webapp，我正在尝试使用restful服务和JBoss 7.0运行时。
我已经更改了web.xml以使用javax.ws.rs来调用restful服务，我已经将jar添加到了buildpath中。服务器启动完美，因此没有与web.xml文件相关的错误或失败，我可以成功调用第一页。
我写了一个名为RestService的类，当我调用另一个url（确切地说是localhost:8080/myPrj/rest/hello/first）时应该做某事，但当我调用url时，它在我的eclipse控制台上显示错误webbrowser 我做错了什么？
请帮助新手

这是我的web.xml 

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">

<servlet-mapping>
      <servlet-name>javax.ws.rs.core.Application</servlet-name>
      <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>
</web-app>

这是Restsservice类

import javax.ws.rs.*;
import javax.ws.rs.core.*;
import url_checker.*;


@Path("/hello")
public class RestService {


        @GET
        @Path("first")
        @Produces(MediaType.TEXT_PLAIN)
        public String hello(){
            System.out.println("here");
            return "Hi everyone";
        }
        @GET
        @Path("go")
        public String go(){
            runProgramMethod();
            return "<p1>Programm running</p1>";
        }
        private void runProgramMethod() {
            MainPauserMethod runner = new MainPauserMethod();


    }
}

这是浏览器上的错误消息：

  

输入状态报告

     

消息错误的参数传递给公众   RestService $ ServerService（RestService）（   org.jboss.resteasy.spi.BadRequestException：找不到消息   body类型的body reader：class内容类型的RestService： /

     

description服务器遇到内部错误（错误的参数   传递给公共RestService $ ServerService（RestService）（   org.jboss.resteasy.spi.BadRequestException：找不到消息   body读物的类型：class RestService的内容类型： / ）那个   阻止它履行这一要求。

这个在日食的控制台上：

由于JAX-RS的实现是RestEasy，您需要使用如下的web.xml：

<web-app id="WebApp_ID" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>Restful Web Application</display-name>

<context-param>
    <param-name>resteasy.scan</param-name>
    <param-value>true</param-value>
</context-param>

<context-param>
    <param-name>resteasy.servlet.mapping.prefix</param-name>
    <param-value>/rest</param-value>
</context-param>

<listener>
    <listener-class>
        org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap
    </listener-class>
</listener>

<servlet>
    <servlet-name>resteasy-servlet</servlet-name>
    <servlet-class>
        org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher
    </servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>resteasy-servlet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

</web-app>
