今天使用Quartz+Spring测试定时任务时，发现报异常：Error creating bean with name ‘org.springframework.scheduling.quartz.SchedulerFactoryBean#0‘ defined in class path resource [applicationContext-quartz.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/transaction/TransactionException

Quartz异常-Error creating bean with name 'org.springframework.scheduling.quartz.SchedulerFactoryBean「建议收藏」

二、问题分析

从异常信息最后我们可以看到org/springframework/transaction/TransactionException，居然报的是事务异常，原来Quartz需要事务支持也就是spring-tx包，而我恰好没有导入这个包，所以导致实例化错误

三、问题解决

在Maven中加入spring-tx包，然后重新启动服务器即可

四、工程源码
