Hibernate @事务性（传播=传播。必需）是否自动提交

hibernate

Hibernate @事务性（传播=传播。必需）是否自动提交,hibernate,spring-4,Hibernate,Spring 4,实施计划如下： @Transactional(propagation = Propagation.REQUIRED) public Users updateUser(Users user); <?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSc

实施计划如下：

@Transactional(propagation = Propagation.REQUIRED)
public Users updateUser(Users user);

如果我使用session.beginTransaction（）.commit（）则仅更新我的数据。但我使用@Transactional，我知道ehich维护会话和事务。有人能告诉我为什么需要手动提交吗
