Spring学习之声明式事物管理

1     public List<Student> selectStudent() {
2         Student s = new Student();
3         s.setName("zhengbin");
4         s.setScore(109);
5         sqlSession.insert("com.zhengbin.entity.studentMapper.addStudent",s);
6         sqlSession.delete("com.zhengbin.entity.studentMapper.delStudent",6);
7         return sqlSession.selectList("com.zhengbin.entity.studentMapper.getStudent");
8     }

　　代码运行的前提是数据库不存在id为6的数据

　　1.如果不加入事物管理，则运行的结果是，第五行成功执行，向数据库插入了新数据

　　2.如果加入事物管理，则运行的结果是，虽然第五行可以执行成功，但第六行不能成功执行，则第五行的操作会回滚，不会将记录写入数据库

声明式事物管理在Spring配置文件beans.xml中的配置：

事务的几种传播特性
1. PROPAGATION_REQUIRED: 如果存在一个事务，则支持当前事务。如果没有事务则开启
2. PROPAGATION_SUPPORTS: 如果存在一个事务，支持当前事务。如果没有事务，则非事务的执行
3. PROPAGATION_MANDATORY: 如果已经存在一个事务，支持当前事务。如果没有一个活动的事务，则抛出异常。
4. PROPAGATION_REQUIRES_NEW: 总是开启一个新的事务。如果一个事务已经存在，则将这个存在的事务挂起。
5. PROPAGATION_NOT_SUPPORTED: 总是非事务地执行，并挂起任何存在的事务。
6. PROPAGATION_NEVER: 总是非事务地执行，如果存在一个活动事务，则抛出异常
7. PROPAGATION_NESTED：如果一个活动的事务存在，则运行在一个嵌套的事务中. 如果没有活动事务,
