本文介绍了在SpringCloud中如何实现Zuul的服务降级，通过配置pom.xml并实现ZuulFallbackProvider接口，当服务端关闭时，Zuul能够提供降级策略，保证系统的稳定性和用户体验。

1、pom.xml

<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-zuul</artifactId>
		</dependency>

2、实现ZuulFallbackProvider接口

package com.zemel.zuul.fallback;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;

import org.springframework.cloud.netflix.zuul.filters.route.ZuulFallbackProvider;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.client.ClientHttpResponse;
import org.springframework.stereotype.Component;

@Component
public class DeptProviderFallback implements ZuulFallbackProvider {

	@Override
	public ClientHttpResponse fallbackResponse() {
		
		return new ClientHttpResponse() {
			
			@Override
			public HttpHeaders getHeaders() {
