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：添加了控制器的代码

编辑 2：添加了服务的接口

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 的执行过程中，JDBCTemplate 会启动一个 RuntimeException，并且不会回滚事务。

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。请参阅我对“为什么 DispatcherServlet 创建另一个应用程序上下文？”的回答。以获得更完整的问题描述。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。

您需要为@Transactional注释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，如果不需要接口（尽管您可能应该编写接口），您可以配置 use proxy-target-class：

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

你的消息SQLException是：

Field 'status' doesn't have a default value

所以也许你正在传递null你应该提供价值的地方？或者，检查这篇文章是否有一些与此错误相关的怪异之处。

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。

我不得不将它移到myapp-servlet.xml我的请求调度程序使用的地方。

现在，它工作正常。
