spring boot @controller @transactional 不起作用

I have @Transactional控制器类中的方法如下： 主要问题是每个服务调用根据日志在其自己的事务中运行。

控制器是否忽略了事务功能？

我希望学生记录不会被保存，因为我在使用另一个服务之后抛出异常，但更新仍然发生在数据库中。我什至有@EnableTransactionManagement在配置类上。你能帮我解决这个问题吗？

@RestController        
@RequestMapping("/api")        
public class Resource {        
@Transactional        
@RequestMapping(value="/test", method = RequestMethod.PUT, produces = "application/json")        
public StudentDTO updateRecord(@RequestBody StudentDTO DTO) throws ApplicationException{ 
    studentservice.find(1234); //jparepository.findone() runs in one transaction       
    studentservice.save(dto); //jparepository.save() runs in one transaction         
    testservice.throwException(); // this method throws application exception        
}        

@Configuration        
@ComponentScan(basePackages={"com.student.*"})        
@EnableAutoConfiguration(exclude = {MetricFilterAutoConfiguration.class, MetricRepositoryAutoConfiguration.class})        
@EnableConfigurationProperties        
@EnableTransactionManagement        
public class Application {        
}       

下面是日志：

[TRACE] org.springframework.transaction.interceptor.TransactionInterceptor -  Getting transaction for   [org.springframework.data.jpa.repository.support.SimpleJpaRepository.findOne]
[TRACE] org.springframework.transaction.interceptor.TransactionInterceptor - Completing transaction for [org.springframework.data.jpa.repository.support.SimpleJpaRepository.findOne]
[TRACE] org.springframework.transaction.interceptor.TransactionInterceptor - Getting transaction for [org.springframework.data.jpa.repository.support.SimpleJpaRepository.save]
[TRACE] org.springframework.transaction.interceptor.TransactionInterceptor - Completing transaction for [org.springframework.data.jpa.repository.support.SimpleJpaRepository.save]
[TRACE] org.springframework.transaction.interceptor.TransactionInterceptor -    Completing transaction for [updaterecord] after exception: xx.xx.ApplicationException
[TRACE]   org.springframework.transaction.interceptor.RuleBasedTransactionAttribute -   Applying rules to determine whether transaction should rollback on   xx.xx.ApplicationException
[TRACE]     org.springframework.transaction.interceptor.RuleBasedTransactionAttribute -    Winning rollback rule is: null
[TRACE]   org.springframework.transaction.interceptor.RuleBasedTransactionAttribute - No   relevant rollback rule found: applying default rules 

我正在使用 spring data jpa，studentservice.find(1234)调用//jparepository.findone()在 1 个事务中运行的方法studentservice.save(dto);调用//jparepository.save()运行在另一个事务中，我们可以从上面的日志中看出

很可能更建议您的事务边界应该在服务层而不是在控制器中声明。
