java - 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。现在我正在尝试通过 JAVA Config(无 XML)设置项目。项目启动，但是当我创建一个新用户(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。如果这个 XML 配置错误没有发生过。

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/>

    <!-- ========================= DATASOURCE DEFINITION ========================= -->

    <!-- Configurer that replaces ${...} placeholders with values from a properties file -->
    <!-- (in this case, JDBC-related settings for the dataSource definition below) -->
    <context:property-placeholder location="classpath:spring/data-access.properties" system-properties-mode="OVERRIDE"/>

    <!-- Database initializer. If any of the script fails, the initialization stops. -->
    <!-- As an alternative, for embedded databases see <jdbc:embedded-database/>. -->
    <jdbc:initialize-database data-source="dataSource">

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)

你的依赖注入(inject)设置不正确.. Controller 应该得到一个 UserService 的 Spring Bean
