我正在研究ejb + JPA（Hibernate）应用程序。当我将数据插入数据库时，它没有被插入。但是没有从sessionbean抛出错误。
以下是代码。
@PersistenceContext private EntityManager em;
@Override
public void insterCustomerDetails(Customer customer) {
// TODO Auto-generated method stub
try{
System.out.println("properties:::"+em.getProperties());
System.out.println("Model :::"+em.getMetamodel());
System.out.println("Name ::::" + customer.getName() + "::customer id ::"+customer.getCustomer_id()+"::email::"+customer.getEmail_id()+"::address::"+customer.getAddress()+
":::ph number::"+customer.getPhNumber());
em.persist(customer);
}catch(Exception e){
e.printStackTrace();
}
}

这是控制台输出：
INFO: Name ::::sdasdas::customer id ::0::email::sdasdasd::address::asdasdasd:::ph number::2323234
INFO: Hibernate:

into
CUSTOMER
(customer_id, addres, email_add, Name, ph_number)
values
(default, ?, ?, ?, ?)
INFO: Hibernate:

我使用derby数据库工具的命令行检查数据库是否插入。客户表中没有行。
现在得到例外：

答案 0 :(得分：0)
您正在使用容器管理的持久性，因此无法强制结束事务。
你想要做的是执行em.flush()。您还需要使用它的事务性来注释EJB方法。所以在其上加@Requires。
