实例：

服务接口:

package com.webservice.service;

/**
 * Created by oracle on 2016/8/3.
 */
public interface XmlWebservice {
    public String getXmlResponse(String reqXml);
}

服务接口实现类：

package com.webservice.service.impl;

import com.webservice.service.XmlWebservice;

import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

/**
 * Created by oracle on 2016/8/3.
 */
@Path("/service")
public class XmlWebserviceImpl implements XmlWebservice {

    @POST
    @Path("/getXmlResponse")
    @Produces("text/xml")
    public String getXmlResponse(String reqXml) {
        System.out.println(reqXml);
        return reqXml;
    }
}

客户端调用：

package com.webservice.client;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;
import org.junit.Test;

import java.io.IOException;

/**
 * Created by oracle on 2016/8/3.
 */
public class Client {

    @Test
    public void testWebservice(){
        HttpClient client=new HttpClient();
        String url="http://localhost:8080/webservice/RESTWebService/service/getXmlResponse";
        PostMethod method=new PostMethod(url);
        method.addParameter("param","6");
        try {
            int responseCode=client.executeMethod(method);
            if(responseCode==200){
                String response=method.getResponseBodyAsString();
                System.out.println(response);
            }else{
                System.out.println("无法访问服务接口");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
