java - log4j 记录到 mysql 表

Question

我想将日志插入到日志表中。和设置操作 log4j.properties :

log4j.rootLogger = DEBUG, DB
log4j.appender.DB=org.apache.log4j.jdbc.JDBCAppender
log4j.appender.DB.URL=jdbc:mysql://localhost/test
log4j.appender.DB.driver=com.mysql.jdbc.Driver
log4j.appender.DB.user=admin
log4j.appender.DB.password=admin
log4j.appender.DB.sql=INSERT INTO logs_2 (log) VALUES('%t')
log4j.appender.DB.layout=org.apache.log4j.PatternLayout

我也试过了

INSERT INTO logs_2 (log) VALUES(''%t'')
INSERT INTO logs_2 (log) VALUES('this is an example log ')
INSERT INTO 'logs_2' (log) VALUES('this is an example log')

表定义:

 CREATE TABLE `logs_2` (
    `id` int(6) unsigned NOT NULL AUTO_INCREMENT,
    `log` varchar(200) DEFAULT NULL,
     PRIMARY KEY (`id`)
 ) ENGINE=InnoDB 

DEFAULT CHARSET=utf8 |

和结果:mysql>....命令行....

MariaDB [test]> select * from logs_2;
Empty set (0.00 sec)

脚本有什么问题？？
