springboot全局异常处理类

注：BusinessException.class 为自定义异常类，替换为需要处理的异常信息类即可

import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

    @ExceptionHandler(BusinessException.class)
    public Object handleException(BusinessException e, HttpServletRequest request){

        log.error("请求：{}发生异常", request.getRequestURI());
        log.error("异常信息：{}", e.getMessage());

        Result result = new Result();
        result.setSuccess(false);
        result.setCode(e.getExcpCode());
        result.setMsg(e.getMessage());

        log.error(result.toJsonString());
        return result;
    }

        result.setSuccess(false);
        if (e instanceof BusinessException) {
            result.setCode(((BusinessException) e).getExcpCode());
            result.setMsg(e.getMessage());
        } else {
