HttpClientUtils工具类，用于java调用其他接口工具类

以下代码是POST请求的，get请求没有封装，比较简单

package com.hxkj.fsslr.core.utils;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;

public class HttpClientUtils {

	private static CloseableHttpClient httpclient;
	
	private static RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(connectTime).setConnectTimeout(connectTime).build();
