Question

Spring Declarative Transaction無效（未提交）。

package com.store.web.front.dao;

    public interface TestDaoIF {
        public void insertTest(Test test);
    }

package com.store.web.front.dao;

    @Repository
    public class TestDaoImpl extends AbstractIBatisDao implements TestDaoIF {    

        Logger logger = Logger.getLogger(TestTxServiceImpl.class);

        @Override
        public void insertTest(Test test) {

            logger.info("# TestDao.insertTest()");

            template.insert("test.insertTest", test);
        }
    }

結果與問題

部署並發送請求“/test/tx.html”后，事務執行沒有問題，但數據庫記錄不會保留。 我想，交易沒有提交。 問題是什么？

Answer 1

我發現了這個問題的原因。 當DispatcherServlet加載事務聲明文件時，事務控制成功。 但是文件是由ContextLoaderListener加載的，事務控制並不好。 我不知道為什么會出現這種差異。 你能跟我解釋一下嗎？

Answer 2

豆子由BeanPostProcessor的“AOP東西”裝飾（在你的情況下可能由AspectJAwareAdvisorAutoProxyCreator ）。 這些后處理器bean是特定於上下文實例的 。

如果在servlet上下文中配置AOP並且在根上下文中有目標bean（反之亦然），那么這就是未應用切入點的原因。

通常的做法是在根上下文中使用較低級別的bean（服務和DAO）以及AOP配置，並在servlet上下文中僅保留UI bean（MVC內容）。
