Entity class

 /*
 MySQL Supports a large number of column types , It can be divided into 3 class ： Numeric type 、 Date and time types and strings ( character ) type .Mysql The solution for character type large object storage is Lob object .

@Lob  Annotation properties will be persisted as  Blog  or  Clob  type 
Clob（Character Large Ojects） Type is a long string type , Concrete java.sql.Clob, Character[], char[]  and  java.lang.String  Will be persisted  Clob  type .
Blob（Binary Large Objects） Type is byte type , Concrete java.sql.Blob, Byte[], byte[]  and  serializable type  Will be persisted  Blob  type .
@Lob  Persist to Blob perhaps Clob type , according to get Method returns different values , Automatically Clob and Blob Transformation .
 Because these two types of data generally occupy a large memory space , So we usually use the method of delayed loading , And @Basic Marks are used at the same time , Set the loading method to FetchType.LAZY.
