java使用idea搭建ssm+maven框架项目，单model，精简配置

最近跟着Gerry老师学习了使用idea搭建ssm+maven框架项目，学完后才发现以前自己使用eclipse搭建的ssm+maven框架有多么乱，至于配置等等更不用说，大都不怎么理解，只知道在网上百度复制粘贴，至于为啥这么配不知道，所以这次重新学习了搭建这个框架感觉收获挺大的，整个配置都是老师手敲的，原理也大都说明了，高手就是不一样。。

package com.gx.common.base.exception;

/**
 * 各个模块中所有自定义业务异常的父类
 */
public class baseBusinessException extends RuntimeException {
    public baseBusinessException（） {
        super（）;
    }

    public baseBusinessException（String message） {
        super（message）;
    }

    public baseBusinessException（String message Throwable cause） {
        super（message cause）;
    }

    public baseBusinessException（Throwable cause） {
        super（cause）;
    }

    protected baseBusinessException（String message Throwable cause boolean enableSuppression boolean writableStackTrace） {
        super（message cause enableSuppression writableStackTrace）;
    }
}
