httpclient postはjson配列を送信しjson乱符号化問題を解決する

業務:クライアントはjsonデータを送信し、サービス側は解析を行う

client  json  ：
{"data":[{"name":"1;,a","id_no":"222,a","cellphone":"123141a","abode_detail":"213,a","emp_add":"werew3a","app_no":"111111111111a","create_time":"11a"},{"name":"  ","id_no":"null","cellphone":"null","abode_detail":"null","emp_add":"null","app_no":"null","create_time":"null"},{"name":"1;,","id_no":"222,","cellphone":"123141","abode_detail":"213,","emp_add":"werew3","app_no":"111111111111","create_time":"11"},{"name":"1;,ab","id_no":"222,ab","cellphone":"123141ab","abode_detail":"213,ab","emp_add":"werew3ab","app_no":"111111111111ab","create_time":"11ab"}],"sendtime":"20160503"}

くだらないことは言わないで、直接主要なコードclient端に行きます

サービス側は最も原始的なservletを採用する
