스프링 + 최대 절전 모드로 응용 프로그램을 만들었지 만 항상이 오류가 발생합니다. 이것은 최대 절전 모드를 사용하는 첫 번째 응용 프로그램입니다. 일부 가이드를 읽었지만이 문제를 해결할 수 없습니다. 내가 어디에서 잘못하고 있습니까?

이것은 내 응용 프로그램의 코드입니다.

당신은 있어야합니다 수 있도록 트랜잭션 지원 ( <tx:annotation-driven>또는 @EnableTransactionManagement)와 선언 을 transactionManager하고 그것을 통해 작동합니다 SessionFactory.

당신은 @Transactional당신의@Repository

으로 @Transactional당신의 @Repository봄 저장소에 트랜잭션 지원을 적용 할 수 있습니다.

Your Student class has no the @javax.persistence.* annotations how @Entity, I am assuming the Mapping Configuration for that class has been defined through XML.

---

I have had the same issue, but in a class that was not a part of the service layer. In my case, the transaction manager was simply obtained from the context by the getBean() method, and the class belonged to the view layer - my project utilizes OpenSessionInView technique.

The sessionFactory.getCurrentSession() method, has been causing the same exception as the author's. The solution for me was rather simple.

Session session;

try {
    session = sessionFactory.getCurrentSession();
} catch (HibernateException e) {
    session = sessionFactory.openSession();
}

If the getCurrentSession() method fails, the openSession() should do the trick.

---

Add the annotation @Transactional of spring in the class service

---

In your xyz.DAOImpl.java

Do the following steps:

//Step-1: Set session factory

@Resource(name="sessionFactory")
private SessionFactory sessionFactory;

public void setSessionFactory(SessionFactory sf)
{
    this.sessionFactory = sf;
}

---

//Step-2: Try to get the current session, and catch the HibernateException exception.

---

//Step-3: If there are any HibernateException exception, then true to get openSession.

try 
{
    //Step-2: Implementation
    session = sessionFactory.getCurrentSession();
} 
catch (HibernateException e) 
{
    //Step-3: Implementation
    session = sessionFactory.openSession();
}

---

I added these configuration in web.xml and it works well for me!

<filter>
    <filter-name>OpenSessionInViewFilter</filter-name>
    <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>
    <init-param>
        <param-name>sessionFactoryBeanName</param-name>
        <param-value>sessionFactory</param-value>
    </init-param>
    <init-param>
        <param-name>flushMode</param-name>
        <param-value>AUTO</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>OpenSessionInViewFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Additionally, the most ranked answer give me clues to prevent application from panic at the first run.

@Transactional =javax.transaction.Transactional put it just beside @Repository

---

I had this error too because in the file where I used @Transactional annotation, I was importing the wrong class

import javax.transaction.Transactional; 

Instead of javax, use

import org.springframework.transaction.annotation.Transactional; 

---

You need to allow transaction to your DAO method. Add,

@Transactional(readOnly = true, propagation=Propagation.NOT_SUPPORTED)

over your dao methods. And @Transactional shoul be of package,

org.springframework.transaction.annotation.Transactional

---

I encountered the same problem and finally found out that the was not defined within the [dispatcher]-servlet.xml where component-scan element enabled @service annotated class.

Simply put with component-scan element together, the problem disappeared.

---

My similar issue got fixed with below 2 approaches.

1. Through manually handling transactions.

   Session session = sessionFactory.getCurrentSession();

   Transaction tx = session.beginTransaction();

   UserInfo user = (UserInfo) session.get(UserInfo.class, 1);

   tx.commit();

2. Tell Spring to open and manage transactions for you in your web.xml filters and Ensure to use @Repository @Transactional

   < filter > < filter-name >hibernateFilter< /filter-name > < filter-class >org.springframework.orm.hibernate5.support.OpenSessionInViewFilter< /filter-class > < init-param > < param-name>sessionFactory < param-value>session.factory < /init-param > < /filter > < filter-mapping > < filter-name>hibernateFilter< /filter-name > < url-pattern>/*< /url-pattern > < /filter-mapping >

Sorry for improper formatting.

My configuration was like this. I had a QuartzJob , a Service Bean , and Dao . as usual it was configured with LocalSessionFactoryBean (for hibernate) , and SchedulerFactoryBean for Quartz framework. while writing the Quartz job , I by mistake annotated it with @Service , I should not have done that because I was using another strategy to wire the QuartzBean using AutowiringSpringBeanJobFactory extending SpringBeanJobFactory.

So what actually was happening is that due to Quartz Autowire , TX was getting injected to the Job Bean and at the same time Tx Context was set by virtue of @Service annotation and hence the TX was falling out of sync !!

I hope it help to those for whom above solutions really didn't solved the issue. I was using Spring 4.2.5 and Hibernate 4.0.1 ,

I see that in this thread there is a unnecessary suggestion to add @Transactional annotation to the DAO(@Repository) , that is a useless suggestion cause @Repository has all what it needs to have don't have to specially set that @transactional on DAOs , as the DAOs are called from the services which have already being injected by @Trasancational . I hope this might be helpful people who are using Quartz , Spring and Hibernate together.

Add transaction-manager to your <annotation-driven/> in spring-servlet.xml:

<tx:annotation-driven transaction-manager="yourTransactionBeanID"/>

---

Check your dao class. It must be like this:

Session session = getCurrentSession();
Query query = session.createQuery(GET_ALL);

And annotations:

@Transactional
@Repository

---

My solution was (using Spring) putting the method that fails inside another method that creates and commits the transaction.

To do that I first injected the following:

@Autowired
private PlatformTransactionManager transactionManager;

And finally did this:

public void newMethod() {
    DefaultTransactionDefinition definition = new DefaultTransactionDefinition();
    TransactionStatus transaction = transactionManager.getTransaction(definition);

    oldMethod();

    transactionManager.commit(transaction);
}

---

In this class above @Repository just placed one more annotation @Transactional it will work.If it works reply back(Y/N)

@Repository

@Transactional

public class StudentDAOImpl implements StudentDAO
