标题: 《深入明白Mybatis原理》MyBatis事务管理机制
概述

对数据库的事务而言，应该具有以下几点：创建（create）、提交（commit）、回滚（rollback）、关闭（close）。对应地，MyBatis将事务抽象成了Transaction接口：

MyBatis的事务管理分为两种形式：
这两者的类图如下所示：

官网关于事务配置的内容

在 MyBatis 中有两种类型的事务管理器（也就是 type="[JDBC|MANAGED]"）：
  1. <transactionManager type="MANAGED">
  2.   <property name="closeConnection" value="false"/>
  3. </transactionManager>
复制代码
如果你正在使用 Spring + MyBatis，则没有须要配置事务管理器，因为 Spring 模块会使用自带的管理器来覆盖前面的配置。
这两种事务管理器类型都不需要设置任何属性。它们其实是类型别名，换句话说，你可以用 TransactionFactory 接口实现类的全限定名或类型别名代替它们。
  1. public interface TransactionFactory {<transactionManager type="MANAGED">
  2.   <property name="closeConnection" value="false"/>
  3. </transactionManager>default void setProperties(Properties props) { // 从 3.5.2 开始，该方法为默认方法<transactionManager type="MANAGED">
  4.   <property name="closeConnection" value="false"/>
  5. </transactionManager><transactionManager type="MANAGED">
  6.   <property name="closeConnection" value="false"/>
  7. </transactionManager>// 空实现<transactionManager type="MANAGED">
  8.   <property name="closeConnection" value="false"/>
  9. </transactionManager>}<transactionManager type="MANAGED">
  10.   <property name="closeConnection" value="false"/>
  11. </transactionManager>Transaction newTransaction(Connection conn);<transactionManager type="MANAGED">
  12.   <property name="closeConnection" value="false"/>
  13. </transactionManager>Transaction newTransaction(DataSource dataSource, TransactionIsolationLevel level, boolean autoCommit);}
复制代码
在事务管理器实例化后，所有在 XML 中配置的属性将会被传递给 setProperties() 方法。你的实现还需要创建一个 Transaction 接口的实现类，这个接口也很简朴：
  1. public interface Transaction {<transactionManager type="MANAGED">
  2.   <property name="closeConnection" value="false"/>
  3. </transactionManager>Connection getConnection() throws SQLException;<transactionManager type="MANAGED">
  4.   <property name="closeConnection" value="false"/>
  5. </transactionManager>void commit() throws SQLException;<transactionManager type="MANAGED">
  6.   <property name="closeConnection" value="false"/>
  7. </transactionManager>void rollback() throws SQLException;<transactionManager type="MANAGED">
  8.   <property name="closeConnection" value="false"/>
  9. </transactionManager>void close() throws SQLException;<transactionManager type="MANAGED">
  10.   <property name="closeConnection" value="false"/>
  11. </transactionManager>Integer getTimeout() throws SQLException;}
复制代码
使用这两个接口，你可以完全自定义 MyBatis 对事务的处理。
事务的配置、创建和使用

事务的配置

我们在使用MyBatis时，一般会在MyBatisXML配置文件中定义类似如下的信息：

节点定义了毗连某个数据库的信息，其子节点 的type 会决定我们用什么类型的事务管理机制。
事务工厂的创建

MyBatis事务的创建是交给TransactionFactory 事务工厂来创建的，如果我们将的type 配置为"JDBC",那么，在MyBatis初始化解析 节点时，会根据type="JDBC"创建一个JdbcTransactionFactory工厂，其源码如下：
  1. /**<transactionManager type="MANAGED">
  2.   <property name="closeConnection" value="false"/>
  3. </transactionManager>* 解析节点，创建对应的TransactionFactory<transactionManager type="MANAGED">
  4.   <property name="closeConnection" value="false"/>
  5. </transactionManager>* @param context<transactionManager type="MANAGED">
  6.   <property name="closeConnection" value="false"/>
  7. </transactionManager>* @return<transactionManager type="MANAGED">
  8.   <property name="closeConnection" value="false"/>
  9. </transactionManager>* @throws Exception<transactionManager type="MANAGED">
  10.   <property name="closeConnection" value="false"/>
  11. </transactionManager>*/<transactionManager type="MANAGED">
  12.   <property name="closeConnection" value="false"/>
  13. </transactionManager>private TransactionFactory transactionManagerElement(XNode context) throws Exception {<transactionManager type="MANAGED">
  14.   <property name="closeConnection" value="false"/>

如上述代码所示，如果type = "JDBC",则MyBatis会创建一个JdbcTransactionFactory.class 实例；如果type="MANAGED"，则MyBatis会创建一个MangedTransactionFactory.class实例。
MyBatis对节点的解析会生成TransactionFactory实例；而对解析会生成datasouce实例，作为节点，会根据TransactionFactory和DataSource实例创建一个Environment对象，代码如下所示：
  1. private void environmentsElement(XNode context) throws Exception {<transactionManager type="MANAGED">
  2.   <property name="closeConnection" value="false"/>
  3. </transactionManager><transactionManager type="MANAGED">
  4.   <property name="closeConnection" value="false"/>
  5. </transactionManager><transactionManager type="MANAGED">
  6.   <property name="closeConnection" value="false"/>
  7. </transactionManager>if (context != null) {<transactionManager type="MANAGED">
  8.   <property name="closeConnection" value="false"/>
  9. </transactionManager><transactionManager type="MANAGED">

Environment表示着一个数据库的毗连，生成后的Environment对象会被设置到Configuration实例中，以供后续的使用。

上述一直在讲事务工厂TransactionFactory来创建的Transaction，现在让我们看一下MyBatis中的TransactionFactory的定义吧。
事务工厂TransactionFactory

事务工厂Transaction定义了创建Transaction的两个方法：一个是通过指定的Connection对象创建Transaction，另外是通过数据源DataSource来创建Transaction。与JDBC 和MANAGED两种Transaction相对应，TransactionFactory有两个对应的实现的子类：

事务Transaction的创建

通过事务工厂TransactionFactory很容易获取到Transaction对象实例。我们以JdbcTransaction为例，看一下JdbcTransactionFactory是怎样生成JdbcTransaction的，代码如下：

如上说是，JdbcTransactionFactory会创建JDBC类型的Transaction，即JdbcTransaction。类似地，ManagedTransactionFactory也会创建ManagedTransaction。下面我们会分别深入JdbcTranaction 和ManagedTransaction，看它们到底是怎样实现事务管理的。
JdbcTransaction

JdbcTransaction直接使用JDBC的提交和回滚事务管理机制。它依靠与从dataSource中取得的毗连connection 来管理transaction 的作用域，connection对象的获取被延迟到调用getConnection()方法。如果autocommit设置为on，开启状态的话，它会忽略commit和rollback。
直观地讲，就是JdbcTransaction是使用的java.sql.Connection 上的commit和rollback功能，JdbcTransaction只是相当于对java.sql.Connection事务处理进行了一次包装（wrapper），Transaction的事务管理都是通过java.sql.Connection实现的。JdbcTransaction的代码实现如下：
  1. public class JdbcTransaction implements Transaction {<transactionManager type="MANAGED">
  2.   <property name="closeConnection" value="false"/>
  3. </transactionManager><transactionManager type="MANAGED">
  4.   <property name="closeConnection" value="false"/>
  5. </transactionManager><transactionManager type="MANAGED">
  6.   <property name="closeConnection" value="false"/>
  7. </transactionManager> private static final Log log = LogFactory.getLog(JdbcTransaction.class);<transactionManager type="MANAGED">
  8.   <property name="closeConnection" value="false"/>
  9. </transactionManager><transactionManager type="MANAGED">

ManagedTransaction

ManagedTransaction让容器来管理事务Transaction的整个生命周期，意思就是说，使用ManagedTransaction的commit和rollback功能不会对事务有任何的影响，它什么都不会做，它将事务管理的权利移交给了容器来实现。看如下Managed的实现代码大家就会一目了然：
  1. /**<transactionManager type="MANAGED">
  2.   <property name="closeConnection" value="false"/>
  3. </transactionManager>*<transactionManager type="MANAGED">
  4.   <property name="closeConnection" value="false"/>
  5. </transactionManager> * 让容器管理事务transaction的整个生命周期<transactionManager type="MANAGED">
  6.   <property name="closeConnection" value="false"/>
  7. </transactionManager>* connection的获取延迟到getConnection()方法的调用<transactionManager type="MANAGED">
  8.   <property name="closeConnection" value="false"/>
  9. </transactionManager>* 忽略所有的commit和rollback使用<transactionManager type="MANAGED">
  10.   <property name="closeConnection" value="false"/>
  11. </transactionManager>* 默认情况下，可以关闭一个毗连connection，也可以配置它不可以关闭一个毗连<transactionManager type="MANAGED">

注意：如果我们使用MyBatis构建当地程序，即不是WEB程序，若将type设置成"MANAGED"，那么，我们实行的任何update使用，即使我们最后实行了commit使用，数据也不会生存，不会对数据库造成任何影响。因为我们将MyBatis配置成了“MANAGED”，即MyBatis自己不管理事务，而我们又是运行的当地程序，没有事务管理功能，所以对数据库的update使用都是无效的。
