我的@Transactionnal注释似乎被忽略了。我对Spring容器的初始化没有错误。看起来我的方法还没有被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是持久的。堆栈跟踪不显示应该包装我的服务方法的任何代理符号。
编辑：添加了控制器代码
编辑2：添加了服务的界面
这是我的服务界面。
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

>
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="DADataSource"/>
</bean>
<tx:annotation-driven />
</beans>
在执行createApplication期间，JDBCTemplate会启动RuntimeException，并且不会回滚事务。

答案 0 :(得分：10)
我的猜测是你将服务bean放在属于调度程序servlet的上下文中，其中只有控制器bean应该存在，然后你在根上下文中声明了你的事务bean。基于注释的事务自动代理仅适用于单个上下文，因此其他（错误）上下文中的服务bean不会受到影响。有关问题的更全面描述，请参阅my answer to "Why DispatcherServlet creates another application context?"。根本问题是您不了解Spring MVC应用程序中上下文的组织方式。
答案 1 :(得分：4)
您需要定义@Transactional注释的界面：
public interface ApplicationsService {
public void createApplication(Application application);
}
具体课程：
@Service
public class ApplicationsServiceImpl {
@Transactional
public void createApplication(Application application) {
// ...
}
}
或者，根据Kevin Welker的评论，如果不想要一个界面（尽管你可能应该编写一个界面），你可以配置使用proxy-target-class：
<tx:annotation-driven proxy-target-class="true" />
修改
来自SQLException的消息是：
Field 'status' doesn't have a default value
所以也许你在null传递你应该提供价值的地方？或者，检查this post是否存在与此错误相关的奇怪现象。
答案 2 :(得分：2)
经过三天的调试，我终于找到了我的注释被忽略的原因。
位于子上下文文件中的<tx:annotation-driven/>指令无权访问其父Spring上下文创建的bean。
我不得不将其移至我的请求调度员使用的myapp-servlet.xml。
现在，它正常运作。
