springMVC中过滤器抛出异常，自定义异常捕获

在过滤器中引入org.springframework.web.servlet.HandlerExceptionResolver

    @Autowired@Qualifier("handlerExceptionResolver")private HandlerExceptionResolver resolver;
// doFilter中处理if (条件1) {if (条件2) {resolver.resolveException(request, response, null, new Myself403ForbiddenException("403ForbiddenException"));return;}filterChain.doFilter(servletRequest, servletResponse);return;}

Spring Boot全局异常处理@RestControllerAdvice只会捕获所有Controller层抛出的异常，在filter当中抛出的异常GlobalExceptionHandler类是感知不到的，所以在filter当中抛出的异常最终会被Spring框架自带的全局异常处理类BasicErrorController捕获
