1. 由spring框架自动化管理

public class ArticleAction {        @Autowired    private IArticleService articleService;    @Autowired    private IArticleClassService articleClassService;                @RequestMapping({
    "/jpatest1.htm"})    @Transactional(rollbackFor = Exception.class,propagation=Propagation.REQUIRED)    public ModelAndView jpatest1(HttpServletRequest request){        ModelAndView mv = new JModelAndView("jpatest.html");                ArticleClass articleClass = this.articleClassService.getObjById(CommUtil.null2Long(163843));        articleClass.setClassName("特色服务2222");        this.articleClassService.update(articleClass);                Article article = this.articleService.getObjByProperty("mark", "join111");        article.setTitle(article.getTitle()+"2222");        this.articleService.update(article);                mv.addObject("status","transaction success");        return mv;    }        @RequestMapping({
    "/jpatest2.htm"})    @Transactional    public ModelAndView jpatest2(HttpServletRequest request){        ModelAndView mv = new JModelAndView("jpatest.html");                ArticleClass articleClass = this.articleClassService.getObjById(CommUtil.null2Long(163843));        articleClass.setClassName("特色服务2222");        this.articleClassService.update(articleClass);                Article article = this.articleService.getObjByProperty("mark", "join111");        article.setTitle(article.getTitle()+"2222");        this.articleService.update(article);                mv.addObject("status","transaction success");        return mv;    }    }

 

 

2. 手动提交事务

public class ArticleAction {        @Autowired    private IArticleService articleService;    @Autowired    private IArticleClassService articleClassService;        /**     * JpaTransactionManager事务管理 .     */    @Resource(name = "transactionManager")    private JpaTransactionManager tm;        @RequestMapping({
    "/jpatest.htm"})    @Transactional(value="transactionManager", rollbackFor = Exception.class)    public ModelAndView jpatest(HttpServletRequest request){        ModelAndView mv = new JModelAndView("jpatest.html");        //事务开始        DefaultTransactionDefinition def = new DefaultTransactionDefinition();        def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);          def.setTimeout(30);        //事务状态        TransactionStatus status = tm.getTransaction(def);                         try {             //此处写持久层逻辑            ArticleClass articleClass = this.articleClassService.getObjById(CommUtil.null2Long(163843));            articleClass.setClassName("特色服务2222");            this.articleClassService.update(articleClass);                        Article article = this.articleService.getObjByProperty("mark", "join111");            article.setTitle(article.getTitle()+"2222");            this.articleService.update(article);                                    tm.commit(status);                        mv.addObject("status","transaction success");        } catch (Exception e) {            System.out.println("出现异常，开始回滚"+e);            if(!status.isCompleted()){                tm.rollback(status);            }            //throw e;        }                return mv;    }    }
