BLOB類型是mysql數據庫常用來存儲，但是通過getBlob()方法獲取值得時候會報錯：

name: user_certify_pic  java-type: [B  column-type: BLOB
實際上 user_certify_pic 對應的java類型並不是Blob的類型，[B 可以通過getString來獲取
java.lang.IllegalArgumentException: Can not set [B field yxm.zyf.love.entity.User.user_certify_pic to com.mysql.jdbc.Blob

jdbc，mysql 數據庫BLOB返回值 [B 的問題
