第7步 统一全局数据处理

什么是全局数据处理

统一处理数据的封装和数据的返回

项目中新增加一个包

创建一个 exception 类 两个http 处理类。 我们在这里统一封装和数据的返回。

package com.bitgeek.core.exception;

/**
 * 全局Exception测试用例
 */
public class SpringException extends RuntimeException {
	private static final long serialVersionUID = 1L;
	
    private String msg;
    private int code = 500;
    
    public Spring_bootException(String msg) {
		super(msg);
		this.msg = msg;
	}
	
	public Spring_bootException(String msg, Throwable e) {
		super(msg, e);
		this.msg = msg;
	}
	
	public Spring_bootException(String msg, int code) {
		super(msg);
		this.msg = msg;
		this.code = code;
	}
	
	public Spring_bootException(String msg, int code, Throwable e) {
		super(msg, e);
		this.msg = msg;
		this.code = code;
	}

	public String getMsg() {
		return msg;
	}

	public void setMsg(String msg) {
		this.msg = msg;
	}

	public int getCode() {
		return code;
	}

	public void setCode(int code) {
		this.code = code;
	}
	
}
