SpringBoot项目中，异常拦截

Posted 2021-02-06 寻找梦想的大熊

SpringBoot自带异常拦截@ControllerAdvice

1.创建一个SellerExceptionHandler类打上@ControllerAdvice标签

@ControllerAdvice
public class SellExceptionHandler {
}

2.创建异常处理程序@ExceptionHandler(value = SellerAuthorizeException.class)表示拦截的异常为SellerAuthorizeException异常

    /**
     * 拦截登录异常
     * @return
     */
    @ExceptionHandler(value = SellerAuthorizeException.class)
    public ModelAndView handlerAuthorizeException(){
        return new ModelAndView("redirect:" + projectUrlConfig.getSell() + "/sell/seller/toLogin");
    }
