mysql隔离级别及事务传播
TRANSACTION(事务隔离级别)
1. ISOLATION_DEFAULT:这是一个PlatfromTransactionManager默认的隔离级别,使用数据库默认的事务隔离级别。
每种数据库的默认隔离级别是不同的,例如SQL Server、Oracle默认Read Commited,MySQL默认Repeatable Read。
另外四个与JDBC的隔离级别相对应,不同的隔离级别采用不同的锁类型来实现,在四种隔离级别中,Serializable的
隔离级别最高,Read Uncommited的隔离级别最低。
2. ISOLATION_READ_UNCOMMITTED:读未提交数据,这是事务最低的隔离级别,在并发的事务中,它充许一个事务可以
读到另一个事务未提交的更新数据。(会出现脏读,不可重复读和幻读)
3. ISOLATION_READ_COMMITTED:读已提交数据,保证在并发的事务中,一个事务修改的数据提交后才能被另外一个事
