无法使用Spring data jpa存储库和JtaTransactionManager在数据库中持久化对象

Question

在我转移到JTAtransactionManager之前，我的代码一直工作得很好，但是在数据库中保存记录但获取记录却工作得很好，我试图找出代码出了什么问题，下面是我的示例TransactionConfig类和service类方法。

@Configuration
@ComponentScan
@EnableTransactionManagement
public class TransactionConfig {


    @Bean(name = "userTransaction")
    public UserTransaction userTransaction() throws Throwable {
        UserTransactionImp userTransactionImp = new UserTransactionImp();
        //userTransactionImp.setTransactionTimeout(10000);
        return userTransactionImp;
    }

    @Bean(name = "atomikosTransactionManager", initMethod = "init", destroyMethod = "close")
    public TransactionManager atomikosTransactionManager() throws Throwable {
        UserTransactionManager userTransactionManager = new UserTransactionManager();
        userTransactionManager.setForceShutdown(false);

        return userTransactionManager;
    }

    @Bean(name = "transactionManager")
    @DependsOn({ "userTransaction", "atomikosTransactionManager" })
    public PlatformTransactionManager transactionManager() throws Throwable {
        UserTransaction userTransaction = userTransaction();

        TransactionManager atomikosTransactionManager = atomikosTransactionManager();
        return new JtaTransactionManager(userTransaction, atomikosTransactionManager);
    }

}


---Employee Service Class Method---

@Transactional
public void appExample() {

    try {

        Employee emp = new Employee();

        emp.setFirstName("Veer");
        emp.setLastName("kumar");

        empRepo.save(emp);
    } catch (Exception e) {
        log.error(e);
    }

}

我认为问题在于emprepo.save()方法调用。由于您使用@Transactional进行事务管理，此调用未提交任何对数据库的更改。

请尝试使用emprepo.saveandflush()，它将立即将数据刷新到数据库中。您可以参考Spring data jpa中save和saveAndFlush之间的答案差异
