Spring+SpirngMVC+Hibernate 配置问题答案

【问题标题】：Spring+SpirngMVC+Hibernate configuration issueSpring+SpirngMVC+Hibernate 配置问题
【发布时间】：2016-12-12 14:54:56
【问题描述】：

我的目的是通过注释使用事务。但是当我只在springmvc-servlet.xml 中使用上下文扫描时，注释事务不起作用。所以我想它应该使用spring框架来注释bean而不是spring-mvc。 spring-mvc 仅用于注释控制器。但是当我启动服务器时，它失败了。以下是错误信息。

或者我应该如何配置它以使其通过注释与事务一起使用？

【问题讨论】：

你能告诉我们你的 bean 定义吗？特别是此错误来自的 TblContactListDAOImpl
我使用注解来定义bean。
我使用注解来定义bean。并且只在 springmvc-servlet.xml 中使用 context-scan 时，没有错误。当我在 applicationContext.xml 和 springmvc-servlet.xml 中使用上下文扫描时，它会显示错误消息。

标签： spring spring-mvc transactions web.xml

【解决方案1】：

在您的 applicationContext.xml 上下文文件中，您正在扫描所有内容，包括您的控制器子包：

<context:component-scan base-package="com.syxing" />

明确排除控制器包：

<context:component-scan base-package="com.syxing">
   <context:exclude-filter type="regex" expression="com\.syxing\.controller\.*">
</context:component-scan>

在您的 servletmvc-servlet.xml 上下文中，您正在正确扫描 controller 包。

不要忘记：servletmvc-servlet.xml 是 servlet 上下文（子上下文），它可以看到您的应用程序上下文 applicationContext.xml（父上下文），但反之则不行。

【讨论】：

我试过了，启动服务器还是显示错误信息。
