JDBCUtils 數據庫操作工具 及 mysql 時間插入問題

本次是數據庫重構，數據進行遷移時mysql數據關於時間的問題解決。異常爲

com.mysql.jdbc.MysqlDataTruncation: Data truncation: Incorrect datetime value: '1989' for column 'check_time' at row 1
	at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:4230)
	at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:4164)
	at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:2615)
	at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:2776)
	at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2838)
	at com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:2082)
	at com.mysql.jdbc.PreparedStatement.execute(PreparedStatement.java:1307)
	at com.jeeplus.common.utils.jdbc.JDBCUtils.main(JDBCUtils.java:126)

sql 語句如下

insert into biz_topic_result (id,patient_id,sample_id,title,check_time,code,photo_url,result_analyze,type,create_by,create_date,update_by,update_date,remarks,del_flag)values('5c2ef8545b724ce5955f3ca5dfc5dd9f','6d98b4b4188e40eda1482ac185071011','aecb6447b9084f6eae509ab8d1728bcb','測試',2018-08-21,'201808211624',null,'正常','topic_result_type_1',1,'2018-08-21',1,'2018-08-21','null',0);

 時間類型出錯。查閱百度後使用日期格式化工具處理

SimpleDateFormat simpleDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
user.setCreateTime(Timestamp.valueOf(simpleDate.format(nowdate)));

sql 語句如下

insert into biz_topic_result (id,patient_id,sample_id,title,check_time,code,photo_url,result_analyze,type,create_by,create_date,update_by,update_date,remarks,del_flag)values('5c2ef8545b724ce5955f3ca5dfc5dd9f','6d98b4b4188e40eda1482ac185071011','aecb6447b9084f6eae509ab8d1728bcb','測試',2018-08-21 00:00:00.0,'201808211624',null,'正常','topic_result_type_1',1,'2018-08-21 00:00:00.0',1,'2018-08-21 00:00:00.0','null',0);

刨錯異常如下

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '00:00:00.0,'201808211624',null,'正常','topic_result_type_1',1,'2018-08-21',1,'' at line 1

後來將其修改爲日期格式  2018-08-21,工具類操作不了數據庫。使用Navicat 可以插入數據，但是時間值全部爲 0000:00:00  00:00。也就是完全插入的空值。

最後通過使用 SimpleDateFormat格式化爲String類型。插入成功。

下面爲此次JDBCUtils工具以及使用
