SpringBoot 處理全局的異常捕獲

我們在寫接口時,會出現一些不可避免的小錯誤,但是每個地方都拋出一個異常又有點耗時耗費精力,還比較繁瑣,所以我們可以定義一個全局的異常捕獲,來告知請求端

import com.qiqi.utils.ExceptionUtil;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.TypeMismatchException;
import org.springframework.web.HttpRequestMethodNotSupportedException;
import org.springframework.web.bind.MissingServletRequestParameterException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
 
/**
 * 全局異常捕獲處理
 */
@ControllerAdvice
public class GlobalExceptionHandler {
    private static final Logger logger = LoggerFactory.getLogger(GlobalExceptionHandler.class);
 
    /**
     * http請求的方法不正確
     */
    @ExceptionHandler(HttpRequestMethodNotSupportedException.class)
    @ResponseBody
    public String httpRequestMethodNotSupportedExceptionHandler(HttpRequestMethodNotSupportedException e) {
        logger.error("http請求的方法不正確:【"+e.getMessage()+"】");
        return ExceptionUtil.resultOf(ResultStatusCode.RequestMethodNotAllowed);
    }
 
    /**
     * 請求參數不全
     */
    @ExceptionHandler(MissingServletRequestParameterException.class)
    @ResponseBody
    public String missingServletRequestParameterExceptionHandler(MissingServletRequestParameterException e) {
        logger.error("請求參數不全:【"+e.getMessage()+"】");
        return ExceptionUtil.resultOf(ResultStatusCode.MissingServletRequestParameter);
    }
 
    /**
     * 請求參數類型不正確
     */
    @ExceptionHandler(TypeMismatchException.class)
    @ResponseBody
    public String typeMismatchExceptionHandler(TypeMismatchException e) {
        logger.error("請求參數類型不正確:【"+e.getMessage()+"】");
        return ExceptionUtil.resultOf(ResultStatusCode.TypeMismatchException);
    }
 
    /**
     * 數據格式不正確
     */
    @ExceptionHandler(DataFormatException.class)
    @ResponseBody
    public String dataFormatExceptionHandler(DataFormatException e) {
        logger.error("數據格式不正確:【"+e.getMessage()+"】");
        return ExceptionUtil.resultOf(ResultStatusCode.DataFormatException);
    }
 
    /**
     * 非法輸入
     */
    @ExceptionHandler(IllegalArgumentException.class)
    @ResponseBody
    public String illegalArgumentExceptionHandler(IllegalArgumentException e) {
        logger.error("非法輸入:【"+e.getMessage()+"】");
        return ExceptionUtil.resultOf(ResultStatusCode.IllegalArgumentException);
    }
 
 
    @ExceptionHandler  //處理其他異常
    @ResponseBody
    public String allExceptionHandler(Exception e){
        logger.error("具體錯誤信息:【"+ExceptionUtil.getErrorMessage(e)+"】"); //會記錄出錯的代碼行等具體信息
        int count = 0; //只打印15行的錯誤堆棧
        for (StackTraceElement stackTraceElement : e.getStackTrace()) {
            logger.error(stackTraceElement.toString());
            if(count++ > 13) break;
        }
        return ExceptionUtil.resultOf(ResultStatusCode.SystemException);
    }
 
}
