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;
方法:
Controller.java
@RequestMapping(params = "executeSearch")
    public String executeSearch(HttpServletRequest request) {
        //测试事物控制。
        infoService.test();
        return "info/search";
    }
    ServiceImpl.java
    public void test(){
        try {
            infoDAO.test();
            throw new Exception();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    Service.java
    @Transactional
    public void test();

    DaoImpl.java
    public void test() {
            WlOperationLog log=this.findEntity();
            log.setUsername("2");
            updateCommit(log);
    }

    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!

你想把事务控制在action层还是service层

satisfactorys
satisfactorys 控制在service层。

那你的controler为什么也有Transactional,而且你springmvc的配置文件中


/context:component-scan 这儿配置的是controler

satisfactorys
satisfactorys 现在去掉了controller上的Transactional还是不对,现在只有service上有Transactional其余地方没有。也开启了事务控制,但是还是不对。
