错误提示:

Unsatisfied dependency expressed through field 'jobService';  nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sysJobServiceImpl': Invocation of init method failed;  nested exception is org.quartz.JobPersistenceException: Couldn't store job: Packet for query is too large (2,128 > 1,024).  You can change this value on the server by setting the 'max_allowed_packet' variable.  [See nested exception: sql.ptions.PacketTooBigException: Packet for query is too large (2,128 > 1,024).  You can change this value on the server by setting the 'max_allowed_packet' variable

mysql数据库中的这个这个东西小于加载数据

可以先输入语句查看:show VARIABLES like '%max_allowed_packet%'; 查询 value

解决方法: 

 第一种:

设置默认值为10M:set global max_allowed_packet = 5*1024*1024;

退出命令行,重启mysql服务,再进入。即可

第二种:

如果恢复默认设置:

修改my.ini  在[mysqld]段或者mysql的server配置段进行修改。(终极修改, 修改后重启数据库,永久生效)

  如下: max_allowed_packet = 5M
