2. 解决：看traceback最终是在调用jdbc时出问题的，尝试修改pom中引入的ojdbc依赖

原依赖：

		
			com.oracle.ojdbc
			ojdbc8
			19.3.0.0
		

修改为：

		
			com.oracle
			ojdbc8
			12.2.0.1
		

 

3. 说明：

这个报错其实很奇怪，后端报错语句如下，很简单的一行，

并且当jobInfo.getJobDesc()为其他值时都正常，只有为某个值时会报错

XxlJobInfo existJobInfo = xxlJobInfoDao.loadByName(jobInfo.getJobDesc());
