原因:在Spring Boot由于全局异常处理@RestControllerAdvice只会去捕获所有Controller层抛出的异常，所以在filter当中抛出的异常异常类是没有感知的

解决方案:添加CustomExceptionFilter过滤器

package com.zy.basy.common.core.filter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.lang.NonNull;

import org.springframework.web.servlet.HandlerExceptionResolver;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Component
public class CustomExceptionFilter extends OncePerRequestFilter {
    @Autowired
    @Qualifier("handlerExceptionResolver")
    private HandlerExceptionResolver resolver;
    @Override
    protected void doFilterInternal(@NonNull HttpServletRequest request, @NonNull HttpServletResponse response, @NonNull FilterChain filterChain) throws ServletException, IOException {
        try {
            filterChain.doFilter(request, response);
        } catch (Exception e) {
            resolver.resolveException(request, response, null, e);

OncePerRequestFilter是什么？
OncePerRequestFilter是SpringBoot提供的一种能够确保在一次请求只通过一次filter，一般情况下我们要自定义Filter都会继承这个类。
What！！！ 一次请求还会过滤多次吗？
Filter base class that...
