公共的异常类、返回值

1、项目中的公共异常类

package com.cinc.permissionservice.exception;

import com.cinc.permissionservice.enums.BackResultEnum;
import lombok.Getter;
import lombok.Setter;

public class BasException extends RuntimeException {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	@Getter
	@Setter
	private String code;
	
	@Getter
	@Setter
	private String msg;
	
	@Getter
	@Setter
	private BackResultEnum backResultEnum;

	
	public BasException(BackResultEnum backResultEnum) {
		super();
		this.backResultEnum = backResultEnum;
		this.code = backResultEnum.getCode();
		this.msg = backResultEnum.getMessage();
	}

	public BasException(String code, String msg) {
		super();
		this.code = code;
		this.msg = msg;
	}

}

　　2、返回值工具类

package com.cinc.permissionservice.utils;

import com.cinc.permissionservice.enums.BackResultEnum;
import com.cinc.permissionservice.exception.BasException;
import com.cinc.permissionservice.vo.BackResult;
import lombok.extern.slf4j.Slf4j;

@Slf4j
public class BackResultUtils {

	public static BackResult success(Object data){
		BackResult result = new BackResult();
		result.setCode(BackResultEnum.SUCCESS.getCode());
		result.setMessage(BackResultEnum.SUCCESS.getMessage());
		result.setData(data);
		return result;
	} 
	
	public static BackResult success(){
		return success(null);
	} 
	
	public static BackResult error(Exception e){
		BackResult result = new BackResult();
		if(e instanceof BasException){
			result.setCode(((BasException) e).getCode());
			result.setMessage(((BasException) e).getMsg());
		}else{
			log.error("【系统错误】",e);
			result.setCode(BackResultEnum.ERROR.getCode());
			result.setMessage(BackResultEnum.ERROR.getMessage());
		}
		return result;
	} 
}

　　

package com.cinc.permissionservice.vo;

import java.io.Serializable;

public class BackResult<T> implements Serializable	{
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	public String code = "000000";
	public String message = "成功";
	public T data;
	
	
	public BackResult(String code, String message) {
		super();
		this.code = code;
		this.message = message;
	}
	
	
	public BackResult() {
		super();
	}


	public String getCode() {
		return code;
	}
	public void setCode(String code) {
		this.code = code;
	}
	public String getMessage() {
		return message;
	}
	public void setMessage(String message) {
		this.message = message;
	}
	public Object getData() {
		return data;
	}
	public void setData(T data) {
		this.data = data;
	}
}
