经过上几次的查找，笔者我就简单的说一下查找的思路，留给读者自己实践
同样找到sqlsession的实现类，----DefaltSqlSession,找它的close方法
public void close() { try { this.executor.close(this.isCommitOrRollbackRequired(false)); this.closeCursors(); this.dirty = false; } finally { ErrorContext.instance().reset(); } }
executor执行器的close方法里面的这个方法，传入false
private boolean isCommitOrRollbackRequired(boolean force) { return !this.autoCommit && this.dirty || force; }
根据上一篇博客写的，他们三个逻辑运算符的优先级 &&>||>!
得到值为true
看executor.close(boolean XXX)的方法，同样找他实现类BaseExecutor
public void close(boolean forceRollback) { try { try { this.rollback(forceRollback); } finally { if(this.transaction != null) { this.transaction.close(); } } } catch (SQLException var11) { log.warn("Unexpected exception on closing transaction. Cause: " + var11); } finally { this.transaction = null; this.deferredLoads = null; this.localCache = null; this.localOutputParameterCache = null; this.closed = true; } }
从头开始看，rollback(true)这一行
public void rollback(boolean required) throws SQLException { if(!this.closed) { try { this.clearLocalCache(); this.flushStatements(true); } finally { if(required) { this.transaction.rollback(); } } } }
finally中是什么事物的回滚啊，这就真相大白
SqlSession中的close在底层调用了事务的回滚的方法，当然会造成事务的回滚啊~~~~~~
