二、网关入门案例
1.创建项目
1.1 添加坐标

1,2 修改配置文件
spring.application.name=zuul-gateway server.port=9020 #设置服务注册中心地址，向所有注册中心做注册 eureka.client.serviceUrl.defaultZone=http://user:123456@eureka1:8761/eureka/,http://user:123456@eureka2:8761/eureka/ 复制代码
1.3 修改启动类
//开启网关代理
@EnableZuulProxy
@SpringBootApplication
public class ZuulApplication {
public static void main(String[] args) {
SpringApplication.run(ZuulApplication.class, args);
}
}
复制代码
1.4 通过网关请求服务
访问： http://IP :网关端口号/请求的服务名/访问的url
三、路由器的4种路由规则方法
1.创建项目
2.采用URL指定路由方式
2.1 修改配置文件
spring.application.name=zuul-gateway-route server.port=9030 #设置服务注册中心地址，向所有注册中心做注册 eureka.client.serviceUrl.defaultZone=http://user:123456@eureka1:8761/eureka/,http://user:123456@eureka2:8761/eureka/ #1.路由指定:URL指定 #URL指定关键字，如果包含关键字就跳转到指定的URL中 zuul.routes.ego-product-provider.path=/ego-product-provider/** zuul.routes.ego-product-provider.url=http://127.0.0.1:9001/ 复制代码
2.2 通配符含义
?：匹配任意单个字符
*：匹配任意数量的任意字符，但是不能添加 /
**：匹配任意数量的任意字符
3.采用服务指定路由方式
#2.路由指定:服务指定1 #将路径的/suibian/引到 eureka的 ego-product-provider 服务上 #规则：zuul.routes.路径名.path #规则：zuul.routes.路径名.serviceId=eureka的服务名 #zuul.routes.ego-product-provider.path=/suibian/** #zuul.routes.ego-product-provider.service-id=ego-product-provider #3.路由指定:服务指定2 #zuul.routes后面跟着的是服务名，服务名后面跟着的是路径规则，这种配置方式更简单。 zuul.routes.ego-product-provider.path=/suibian/** 复制代码
4.路由的排除法
#4.路由排除:排除某几个服务 #排除后，这个地址将为空， http://127.0.0.1:9030/ego-product-provider/product/findAll #多个服务使用逗号分开 #zuul.ignored-services=ego-product-provider #5.路由排除:排除所有服务 #由于路由太多，不可能全部手动添加，故路由排除所有服务，然后针对要路由的服务进行手动添加 #zuul.ignored-services=* #zuul.routes.ego-product-provider=/ego-product-provider/** #6.路由排除:排除指定关键字的路径 #排除所有包括/list/的路径 #zuul.ignored-patterns=/**/findAll/** zuul.routes.ego-product-provider.path=/ego-product-provider/** 复制代码
5.路由的添加前缀方法
#7.路由添加前缀:为所有路径添加前缀 #http://127.0.0.1:9030/ego-product-provider/product/findAll #必须改成 #http://127.0.0.1:9030/api/suibian/product/findAll #zuul.prefix=/api zuul.routes.ego-product-provider.path=/suibian/** 复制代码
四、自定义网关过滤器
1.编写网关过滤器

1.4 编写filter
@Component
public class LogFilter extends ZuulFilter {
private static final Logger LOGGER = LoggerFactory.getLogger(LogFilter.class);
/**
* 过滤器类型，通过过滤器类型决定了过滤器执行的时机
* @return
*/
@Override
public String filterType() {
//在路由之前执行
return "pre";
}
/**
* 过滤器的执行顺序：通过返回的整数表示顺序，数值越小优先级越高
* @return
*/
@Override
public int filterOrder() {
return 0;
}
/**
* 是否开启过滤器，默认为false
* @return
*/
@Override
public boolean shouldFilter() {
return true;
}
/**
* 过滤内容：在run方法中编写过滤逻辑
* @return
*/
@Override
public Object run() {
//获取请求上下文
RequestContext requestContext = RequestContext.getCurrentContext();
//获取请求方式
HttpServletRequest request = requestContext.getRequest();
LOGGER.info("LogFilter...method={},url={}", request.getMethod(), request.getRequestURL().toString());
return null;
}
}
复制代码
1.5 修改启动类
//开启网关代理
@EnableZuulProxy
@SpringBootApplication
public class ZuulApplication {
public static void main(String[] args) {
SpringApplication.run(ZuulApplication.class, args);
}
}
复制代码
2.过滤器类型
3.Zuul请求的生命周期
4.采用网关过滤器实现权限验证
需求：在网关过滤器中通过Token判断用户是否登录

4.4 创建AccessFilter

@Component
public class AccessFilter extends ZuulFilter {
private static final Logger LOGGER = LoggerFactory.getLogger(AccessFilter.class);
/**

复制代码
AccessFilter2
/**
* 执行顺序演示
*/
@Component
public class AccessFilter2 extends ZuulFilter {
private static final Logger LOGGER = LoggerFactory.getLogger(AccessFilter2.class);
/**
* 过滤器类型，通过过滤器类型决定了过滤器执行的时机
* @return
*/
@Override
public String filterType() {
//在路由之前执行
return "pre";

return 1;
}
/**

@Component
public class PostFilter extends ZuulFilter {
private static final Logger LOGGER = LoggerFactory.getLogger(PostFilter.class);
/**

*/
@Override
public String filterType() {
return "post";
}
/**

@Override
public int filterOrder() {
return 0;
}
/**

//获取请求上下文
RequestContext requestContext = RequestContext.getCurrentContext();
//获取请求方式
HttpServletRequest request = requestContext.getRequest();
LOGGER.info("------------------post------------------------");
return null;
}
}
复制代码
6.采用网关过滤器对异常进行统一处理
6.1 创建 ErrorFilter
/**
* error类型演示
*/
@Component
public class ErrorFilter extends ZuulFilter {
private static final Logger LOGGER = LoggerFactory.getLogger(ErrorFilter.class);
/**
* 过滤器类型，通过过滤器类型决定了过滤器执行的时机
* @return
*/
@Override
public String filterType() {
return "error";
}
/**
* 过滤器的执行顺序：通过返回的整数表示顺序，数值越小优先级越高
* @return
*/
@Override
public int filterOrder() {
return 1;
}
/**
* 是否开启过滤器，默认为false
* @return
*/
@Override
public boolean shouldFilter() {
return true;
}
/**
* 过滤内容：在run方法中编写过滤逻辑
* @return
*/
@Override
public Object run() {
//获取请求上下文
RequestContext requestContext = RequestContext.getCurrentContext();
//获取请求方式
HttpServletRequest request = requestContext.getRequest();
LOGGER.info("------------------error------------------------");
return null;
}
}
复制代码
6.2 创建ExceptionHandler
/**
* 对异常响应内容处理
*/
@RestController
public class ExceptionHandler implements ErrorController {
@Override
public String getErrorPath() {
return "/error";
}
@RequestMapping(value = "error")
public String error(){
return "{'result':'500 error'}";
}
}
复制代码
五、网关容错
1.zuul和hystrix无缝结合
在zuul的jar包中包含了hystrix的jar包。所以我们不需要在项目中添加hystrix的坐标。
2.访问网关服务的数据监控流
3.启动dashboard-view服务监控健康状况
4.在网关中实现对服务的降级处理
4.1 创建项目
4.2 添加坐标

4.4 添加ProductFallbackProvider类
/**
* 对Product-Provider做降级处理
*/
@Component
public class ProductFallbackProvider implements ZuulFallbackProvider {
/**
* 给定对哪个服务做降级处理
* @return
*/
@Override
public String getRoute() {
//指定做降级的服务名

return HttpStatus.OK;

@Override
public HttpHeaders getHeaders() {
HttpHeaders httpHeaders = new HttpHeaders();
MediaType mediaType = new MediaType("application", "json", Charset.forName("utf-8"));
httpHeaders.setContentType(mediaType);
return httpHeaders;
}
};
}
}

3.修改配置文件
3.1 全局限流
spring.application.name=zuul-gateway-ratelimit server.port=9020 #设置服务注册中心地址，向所有注册中心做注册 eureka.client.serviceUrl.defaultZone=http://user:123456@eureka1:8761/eureka/,http://user:123456@eureka2:8761/eureka/ zuul.routes.ego-product-provider.path=/product/** zuul.routes.ego-product-provider.service-id=ego-product-provider #全局配置限流 zuul.ratelimit.enabled=true #60s内超过3次请求服务端就抛出异常，60s后可以恢复正常请求 zuul.ratelimit.default-policy.limit=3 zuul.ratelimit.default-policy.refresh-interval=60 #针对IP进行限流，不影响其他IP zuul.ratelimit.default-policy.type=origin 复制代码
3.2 测试
3.3 局部限流

4.网关限流参数
七、zuul性能调优：网关的2层超时调优
1.创建项目
2.添加坐标

spring.application.name=zuul-gateway-timeout server.port=9020 #设置服务注册中心地址，向所有注册中心做注册 eureka.client.serviceUrl.defaultZone=http://user:123456@eureka1:8761/eureka/,http://user:123456@eureka2:8761/eureka/ #第一层hystrix超时时间设置 hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=8000 #第二层ribbon超时时间设置，设置的比第一层小 #连接超时时间，默认5s ribbon.ConnectTimeout=5000 #请求处理的超时时间，默认5s ribbon.ReadTimeout=5000 复制代码
