java发送消息体是xml等格式的http报文

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.InputStreamRequestEntity;
import org.apache.commons.httpclient.methods.PutMethod;
import org.apache.commons.httpclient.methods.RequestEntity;

//通过java发送http请求
//data可以是xml格式
private static String sendRequest(String url,String data){
