MyBatis tostring() may result in the creation of a sqlsession

https://github.com/mybatis/mybatis-3/blob/master/src/main/java/org/apache/ibatis/session/SqlSessionManager.java#L346-L366

During ide breakpoint debugging, the tostring() method is called because the IDE will display the value of the method parameter proxy, which may lead to the creation of Sqlsession

Hello @brucelwl ,

Bad things happen if you use IDE incorrectly and we don't add extra code for that.

IDE wouldn't invoke toString() unless you click the variable or something. Please be careful. :)
