execute

public Object execute(Config config,
                      com.litongjava.model.db.ICallback callback)

Execute callback. It is useful when all the API can not satisfy your requirement.

Parameters:

config - the Config object

callback - the ICallback interface

tx

public boolean tx(Config config,
                  int transactionLevel,
                  com.litongjava.model.db.IAtom atom)

Parameters:

config - the Config object

transactionLevel - the transaction level

atom - the atom operation

Returns:

true if transaction executing succeed otherwise false

tx

txInNewThread

public Future<Boolean> txInNewThread(com.litongjava.model.db.IAtom atom)

主要用于嵌套事务场景

实例：https://jfinal.com/feedback/4008

默认情况下嵌套事务会被合并成为一个事务，那么内层与外层任何地方回滚事务 所有嵌套层都将回滚事务，也就是说嵌套事务无法独立提交与回滚

使用 txInNewThread(...) 方法可以实现层之间的事务控制的独立性 由于事务处理是将 Connection 绑定到线程上的，所以 txInNewThread(...) 通过建立新线程来实现嵌套事务的独立控制

txInNewThread

public Future<Boolean> txInNewThread(int transactionLevel,
                                     com.litongjava.model.db.IAtom atom)
