关于springboot异常处理

系统级错误：主要用于系统产生的错误

package com.xyy.config.exception;


public class SystemException extends RuntimeException{
	private static final long serialVersionUID = -601766030687951565L;
	
	public SystemException(String message) {
		super(message);
	}
	
	public SystemException(Throwable cause){
		super(cause);
	}
	
	public SystemException(String message, Throwable cause){
		super(message, cause);
	}
	

}

全局异常处理

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;

import com.config.web.mvc.AjaxResult;
import com.config.web.mvc.BaseController;

@RestControllerAdvice
public class GlobalExceptionHandler extends BaseController{
	
	private Logger logger = LoggerFactory.getLogger(GlobalExceptionHandler.class);

	@ExceptionHandler(value={RuntimeException.class,SystemException.class,Exception.class})
	public AjaxResult unauthorized(Exception exception, HttpServletRequest request){
		logger.error("全局异常捕捉通知 ",exception); 
		if(exception instanceof BusinessException){
			return ajaxResult(Status.ERROR,exception.getMessage());
		} 
		return ajaxResult(Status.ERROR, "请求失败，请重试");
	}
}
