import org.springframework.web.bind.annotation.RestControllerAdvice;

import com.serlyf.server.pojo.Result;

@RestControllerAdvice
public class GlobalException {

public Result mySQLException(SQLException e){
    if (e instanceof SQLIntegrityConstraintViolationException){
        return Result.ERROR("该数据有关数据，操作失败！");
