Error Handler ExamplesHere are some examples of handler declarations:If any error condition arises (other than a not FOUND), continue execution after setting L_error=1:DECLARE CONTINUE HANDLER for SQLEXCEPTIONSET l_error=1;If any error condition arises ("other than a not FOUND"), exit the current block or stored program after issuing a ROLLBACK Statement and issuing an error message:DECLARE EXIT HANDLER for SQLEXCEPTIONBEGINROLLBACK;SELECT ' Error occurred–terminating ';End;If MySQL Error 1062 (

Problems encountered in the project I. Spring transaction problems 1. Description: a in service1 calls B, B calls c in service2, and c calls d in service3 Expectation: When d throws an exception (the SQL exception is thrown in my real project), d and c will be rolled back, while a and B will not be rolled back. Test: Considering the self-tuning of Spring transactions and the spring transaction configuration under the cglib dynamic proxy. Added Demo: Custom exception:Public class MyException ext
