下面是applicationContext.xml的配置:

注意:事务是管理一系列动作的,其中任何一步操作失败都要回滚才合理。service平行调用事务不生效,建议: 不要在controller写逻辑处理。正确的次序为:controller>service>mapper
示例代码(只是引导方法取名):
@Autowired DBMapper mapper; public void insertDoSomething(){ try{ mappper.add("sssssssssssssssssssss");// 有序操作一 mapper.deleteAll();// 有序操作二 }catch(Exception e){ } }
