Spring @Transactional 注释被忽略答案

【问题标题】：Spring @Transactional annotations ignoredSpring @Transactional 注释被忽略
【发布时间】：2012-05-19 06:46:07
【问题描述】：

我的@Transactionnal 注释似乎被忽略了。我对 Spring 容器的初始化没有错误。看起来我的方法没有被 Spring TX 框架代理。在执行我的服务方法期间，JDBCTemplate 会抛出预期的 RuntimeException。问题是 JDBC 连接没有回滚并且更改被保留。堆栈跟踪没有显示应该包装我的服务方法的代理的任何迹象。

编辑：添加控制器的代码

编辑 2：添加服务接口

这是我的服务接口。

public interface ApplicationsService {
    public Application getApplicationById(int id);

    public void createApplication(Application application);

    public void createInstance(Application application);

    public Map<Integer, Application> getUserApplications(String username);

    public Application newApplication(String email);
}

这是我的服务。

@Service
public class ApplicationsServiceImpl implements ApplicationsService {
    ...
    @Transactional
    public void createApplication(Application application){
        // Persisting the application.
        applicationDAO.createApplication(application);
        application.setId(
            applicationDAO.findApplicationId(application.getName(), application.getAccount().getEmail())
        );

        // Creating the physical instance.
        createInstance(application);
    }
    ...
}

Spring Controller 负责方法调用。

@Controller
@RequestMapping("/applications")
public class ApplicationsController {
    ...
    @Autowired
    private ApplicationsService applicationsService;
    ...

    @RequestMapping(method=RequestMethod.POST)
    public String saveApplication(
        @Valid Application application, 
        BindingResult bindingResult, 
        Principal principal
    ){  
        application.setAccount(this.accountService.getAccount(principal.getName()));
        this.applicationsService.createApplication(application);

        return "application/creatingApplication";
    }
    ...
}

这是我的 Spring 事务配置

<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="    http://www.springframework.org/schema/beans
                            http://www.springframework.org/schema/beans/spring-beans-3.1.xsd

                            http://www.springframework.org/schema/tx
                            http://www.springframework.org/schema/tx/spring-tx-3.1.xsd"
>
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="DADataSource"/>
    </bean>

    <tx:annotation-driven />
</beans>

在 createApplication 执行过程中，JDBCTemplate 会引发 RuntimeException 并且事务不会回滚。

【问题讨论】：

您的createApplication() 方法是否被同一类中的不同方法调用？还是从外部调用它，由另一个注入ApplicationService 的类？
没关系，我刚刚在您的堆栈跟踪中看到它正在被外部调用。
您的实体对象Application 是否有一个名为status 的字段。请检查数据库级别的约束。它是否需要任何默认值？您使用的是哪个数据库？如果您也发布您的实体代码会很好。
我很清楚我有 SQLException 的原因。事实上，我希望这个异常会触发我的事务回滚，这不会发生。
看起来其他人也有同样的问题：stackoverflow.com/q/9930965/1387094

标签： java spring jdbc transactions annotations

【解决方案1】：

我的猜测是您已经将服务 bean 放在属于调度程序 servlet 的上下文中，其中应该只有控制器 bean，然后您已经在根上下文中声明了事务 bean。基于注释的事务自动代理仅适用于单个上下文，因此您在另一个（错误）上下文中的服务 bean 不会受到影响。有关问题的更完整描述，请参阅 my answer to "Why DispatcherServlet creates another application context?"。根本问题是您不了解 Spring MVC 应用程序中的上下文是如何组织的。

【讨论】：

也许你可以指出好的文本来解释上下文是如何组织的？谢谢你:)

【解决方案2】：

您需要为@Transactional 注解定义一个接口才能工作：

public interface ApplicationsService {
    public void createApplication(Application application);
}

具体类：

@Service
public class ApplicationsServiceImpl {
    @Transactional
    public void createApplication(Application application) {
        // ...
    }
}

或者，根据 Kevin Welker 的评论，如果不想要接口（尽管您可能应该编写接口），您可以配置使用 proxy-target-class：

<tx:annotation-driven proxy-target-class="true" />

编辑

来自您SQLException 的消息是：

Field 'status' doesn't have a default value

所以也许你传入null 你应该在哪里提供一个值？或者，检查this post 以了解与此错误相关的一些奇怪之处。

【讨论】：

它不必是一个接口，如果你配置类代理。见this answer for more
我尝试使用界面，但仍然有相同的结果。我会更新我所做的更改。
如果和restlet一起使用，你不需要接口，也不需要配置任何东西，只需要从restlet调用的方法获得事务。

【解决方案3】：

经过三天的调试，终于找到了我的注解被忽略的原因。

位于子上下文文件中的<tx:annotation-driven/> 指令无权访问由其父 Spring 上下文创建的 bean。

我必须将它移动到我的请求调度程序使用的myapp-servlet.xml。

现在，它工作正常。

【讨论】：

这不是正确的解决方案。这充其量只是一种解决方法，并且您误解了哪个上下文是父级，哪个是子级。有关正确的解释/解决方案，请参阅my answer。
