比如這個(gè)util每次調(diào)用doGet時(shí)生成一個(gè)httpClient實(shí)例publicstaticStringdoGet(Stringurl,Mapparam){//創(chuàng)建Httpclient對(duì)象CloseableHttpClienthttpClient=HttpClients.createDefault();難道不可以在這個(gè)util類中加httpClient的靜態(tài)實(shí)例成員嗎，所有doGET,doPost調(diào)用都用同一個(gè)httpClient的靜態(tài)實(shí)例成員,如下publicclassHttpClientUtil{privatestaticCloseableHttpClienthttpClient=HttpClients.createDefault();publicstaticStringdoGet(Stringurl,Mapparam){....response=httpClient.execute(httpGet);
