JPA事务问题Executing an updatedelete query

问题代码

///删除操作 @RequestMapping("/delete") public String delete(){ Pmarea p = new Pmarea(); //p.setName("葫芦岛吴奇隆"); p.setId(10); textDao.delete(p); return "delete ok"; }

报出异常： There was an unexpected error (type=Internal Server Error, status=500). Executing an update/delete query 因为jpa没有事务不能进行删除和修改操作 所以加上**@Transactional**事务注解就好了

///删除操作 @RequestMapping("/delete") @Transactional public String delete(){ Pmarea p = new Pmarea(); //p.setName("葫芦岛吴奇隆"); p.setId(10); textDao.delete(p); return "delete ok"; }
