spring 事务管理 随笔

今天看了下我们系统框架使用的SPRING 事务管理 方式 ，也顺便翻了翻SPRING原代码，把看到的东西记下！

spring 代码 DefaultTransactionDefinition类

private int propagationBehavior = PROPAGATION_REQUIRED;<br />private int isolationLevel = ISOLATION_DEFAULT;<br />private int timeout = TIMEOUT_DEFAULT;<br />private boolean readOnly = false;<br />private String name;</p> <p>/**<br />* Create a new DefaultTransactionDefinition, with default settings.<br />* Can be modified through bean property setters.<br />* @see #setPropagationBehavior<br />* @see #setIsolationLevel<br />* @see #setTimeout<br />* @see #setReadOnly<br />* @see #setName<br />*/<br />public DefaultTransactionDefinition() {<br />}<br /> 

SPRING 代码 AbstractPlatformTransactionManager类

//———————————————————————<br /> // Implementation of PlatformTransactionManager<br /> //———————————————————————<br /> /**<br /> * This implementation handles propagation behavior. Delegates to<br /> * <code>doGetTransaction</code>, <code>isExistingTransaction</code><br /> * and <code>doBegin</code>.<br /> * @see #doGetTransaction<br /> * @see #isExistingTransaction<br /> * @see #doBegin<br /> */<br /> public final TransactionStatus getTransaction(TransactionDefinition definition) throws TransactionException {<br /> Object transaction = doGetTransaction();<br /> // Cache debug flag to avoid repeated checks.<br /> boolean debugEnabled = logger.isDebugEnabled();<br /> if (definition == null) {<br /> // Use defaults if no transaction definition given.<br /> definition = new DefaultTransactionDefinition();<br /> }
