为了定时执行一项任务,设置了Quartz , 但是运行后异常" Failure obtaining db row lock: Table ‘hibernate.qrtz_locks’ doesn’t exist“,相信你肯定会感到困惑,甚至也许会奇怪为什么 SchedulerFactoryBean 和数据持久层有关。

原因:

事实上,这个异常是由于 Spring 的 autowire 属性引起的,SchedulerFactoryBean  类含有方法 : setDataSource. 因为autowire 属性使用了 autodetect , 并且也设置了 datasource 在项目中, spring 容器就自动将 dataSource 注入到SchedulerFactoryBean, 而SchedulerFactoryBean将从 dataSource 中查找计划任务。 但 dataSource 中并没有任务,因此抛出了异常。

幸运的是,当你知道了根本原因,就知道如何避免了。

解决方法:

不论 spring 的 default-autowire 设置为"autodetect " 还是 "byName" ,都会出现 *.QRTZ_LOCKS' doesn't exist

方法一: 不使用 default-autowire 属性;

方法二: 在不改变 spring default-autowire  属性的前提下, 给 SchedulerFactoryBean  设置 autowire="no"。

[xhtml] view plain copy
 
  1. <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean" autowire="no">  
  2.         <property name="triggers">  
  3.             <list>  
  4.                 <ref bean="simpleTriggerBean" />  
  5.             </list>  
  6.         </property>  
  7. </bean>  
 
 
  • 原理:
<bean id="scheduler" lazy-init="false"
      class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
此bean会试图访问数据库获取quartz的一些管理表信息,自然访问数据库时需要注入dataSource bean,当缺省autowire为no,则没有dataSource bean被注入,quartz会认为项目没连数据库,会BYPASS这个访问管理表的功能.
当你配置了default-autowire=byName时,dataSource bean被自动注入,这时quartz认为项目既然能连到数据库,就想当然的认为对应的那些表一定存在,没找到时就出异常.

  • 解决办法:
1.去掉default-autowire=byName即可
此法简单,但往往很难决定,因为缺省,谁也不会傻乎乎的显示配这么一条,配了它一定是有用到它的地方.你愿不愿意牺牲这部分byName注入的功能?

2.在库中建对应的表
此法不可取,因为非常麻烦,要建很多表
CREATE TABLE QRTZ_LOCKS
CREATE TABLE QRTZ_JOB_DETAILS
CREATE TABLE QRTZ_TRIGGERS
CREATE TABLE QRTZ_FIRED_TRIGGERS
CREATE TABLE QRTZ_JOB_LISTENERS
少一张,spring都报异常, 这是为大型调度功能准备的.你要有上百个任务,可能需要它.

3.bean里直接关掉autowired
推荐此法
