Spring中的事务错误

Question

我有一个项目 https://github.com/ivartanian/onlinecontrol  在Spring MVC + JPA中，最初通过XML使用Spring配置。现在我试图通过JAVA Config（没有XML）设置项目。项目启动，但是当我创建新用户（实体用户）时，出现错误事务。但是，如果我创建另一个实体，则不会发生此错误。如果不发生此XML配置错误。

请告诉我错误的原因。 我很乐意提供任何帮助

我的XML配置是：

    <context:component-scan
            base-package="com.vizaco.onlinecontrol.service"/>

    <!-- enables scanning for @Transactional annotations -->
    <tx:annotation-driven/>

    <!-- Configurer that replaces ${...} placeholders with values from a properties file -->
    <!-- (in this case, JDBC-related settings for the dataSource definition below) -->

    <!-- Database initializer. If any of the script fails, the initialization stops. -->

Answer 1

在堆栈跟踪中，这两行之间没有列出Spring AOP类：

   at com.vizaco.onlinecontrol.service.impl.UserServiceImpl.saveUser(UserServiceImpl.java:51)
    at com.vizaco.onlinecontrol.controller.UserController.createUser(UserController.java:112)

您的依赖注入设置不正确.. Controller应该获得UserService的Spring Bean
