以上为配置文件:包路径分别为com.tb.action;com.tb.service;com.tb.model;com.tb.dao; 其中com.tb.service下面又分com.tb.service.impl;com.tb.dao包下又分com.tb.dao.impl; 但是现在测试事物一直控制不了,请大神帮忙原因。测试方法: Controller.java @RequestMapping(params = "executeSearch") @Transactional public String executeSearch(HttpServletRequest request) { //测试事物控制。 infoService.test(); return "info/search"; } ServiceImpl.java public void test(){ try { infoDAO.test(); } catch (Exception e) { e.printStackTrace(); } } Service.java @Transactional public void test(); DaoImpl.java @Transactional public void test() { try { String sql = "update operation_log set username='1' where id='1'"; List<Object> condition = new ArrayList<Object>(); this.executeUpdateBySql(sql, condition); String sql1 = "update operation_log set username=33, where id='1'"; this.executeUpdateBySql(sql1, condition); } catch (RuntimeException e) { e.printStackTrace(); } } DaoImpl.java继承HibernateDao HibernateDao.java /***************注入***********/ @Resource private SessionFactory sessionFactory; public SessionFactory getSessionFactory() { return sessionFactory; } public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } public Session getSession() { //事务配置后,可通过getCurrentSession方法获得session return sessionFactory.getCurrentSession(); } public int executeUpdateBySql(final String sql,final List<Object> conditions){ try { Query query = getSession().createSQLQuery(sql); if(conditions!=null && conditions.size()>0){ for(int i=0;i<conditions.size();i++){ if(conditions.get(i)!=null && !conditions.get(i).equals("")){ query.setParameter(i, conditions.get(i)); } } } return query.executeUpdate(); } catch (RuntimeException e) { throw e; }finally{ System.out.println(getSessionFactory().getCurrentSession().beginTransaction().isActive()); } } 整体代码是这样的,在运行daoImpl.java中test()方法的时候执行第一条SQL时会提交事物,直接修改数据库中的值,执行第二条SQL时会报错,理论上应该都不提交事物。但实际上第一条执行了之后就提交事物了,不知道是我框架问题还是我写的问题,求大神帮忙指出问题所在。万分感谢!
解决方案
问题呢?说一下问题是什么吧~
解决方案二:
@Transactional注解是默认遇到throw new RuntimeException("...");会回滚,你的test方法中运行的话有没有进入异常分支呢,如果没有的话,那么你描述的现象就是正常的啊。
解决方案三:
在controller-servlet.xml中添加:
解决方案四:
在controller-servlet.xml中添加:
解决方案五:
在controller-servlet.xml中添加:
<tx:annotation-driven transaction-manager="transactionManager" />
