拷贝HttpRequestBase对象

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>>

在实践性能测试框架第二版的过程中，我实现了一个单个HttpRequestBase对象的concurrent对象创建，单之前都是用使用唯一的HttpRequestBase对象进行多线程请求，目前来看是没有问题的，但为了防止以后出现意外BUG和统一concurrent的构造方法使用，故尝试拷贝了一个HttpRequestBase对象。原因是因为之前封装的深拷贝方法对于HttpRequestBase对象的实现类如：httpget和httppost并不适用，因为没有实现Serializable接口。所以单独写了一个HttpRequestBase对象的拷贝方法，供大家参考。

下面是FunRequest类的代码，深拷贝的静态方法在最后。

package com.fun.frame.httpclient

import com.fun.base.bean.RequestInfo
import com.fun.base.exception.RequestException
import com.fun.config.HttpClientConstant
import com.fun.config.RequestType
import net.sf.json.JSONObject
import org.apache.commons.lang3.StringUtils
import org.apache.http.Header
import org.apache.http.HttpEntity
import org.apache.http.client.methods.HttpPost
import org.apache.http.client.methods.HttpRequestBase
import org.apache.http.util.EntityUtils
import org.slf4j.Logger
import org.slf4j.LoggerFactory
