如何在Spring Boot中拒绝请求中的3位时间？

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

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

public class TimeInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {
        String time = request.getParameter("time");
        if (time != null && time.length() == 3) {
            // 如果时间长度为3，则拒绝请求
            response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
            return false;
        }
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
            ModelAndView modelAndView) throws Exception {
        // 在请求处理之后调用，但是在视图被渲染之前（Controller方法调用之后）
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
            throws Exception {
        // 在整个请求结束之后被调用，也就是在DispatcherServlet渲染了对应的视图之后执行（主要是用于进行资源清理工作）
    }
}

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebConfig implements WebMvcConfigurer {

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new TimeInterceptor()).addPathPatterns("/**");
    }
}
