GateWay实现负载均衡
通过GateWayThere are two ways to achieve load balancing
自动负载均衡
First look at the gateway service9999的yml配置:
gateway.discovery.locator.enabled: true #开启自动路由功能
routes中的uri其实最后是不需要服务名称的,这个位置其实只需要指定的localhost:9001即可
server:
port: 9999
spring:
application:
name: cloud-gateway-service
cloud:
nacos:
discovery:
server-addr: localhost:8848
gateway:
discovery:
locator:
enabled: true #开启自动路由功能,根据服务名称自动创建routes
routes: # 路由
- id: nacos-provider #路由ID,没有固定要求,但是要保证唯一,建议配合服务名
uri: http://localhost:9001/nacos-provider # 匹配提供服务的路由地址
predicates: # 断言
- Path=/th/** # 断言,路径相匹配进行路由
So this position can optimize the current configuration to the following situation,It can be started just as well,A test start is possible9001和网关9999,access through the gateway"localhost:9999/th/**"
server:
port: 9999
spring:
application:
name: cloud-gateway-service
cloud:
nacos:
discovery:
server-addr: localhost:8848
gateway:
routes: # 路由
- id: nacos-provider #路由ID,没有固定要求,但是要保证唯一,建议配合服务名
uri: http://localhost:9001 # 匹配提供服务的路由地址
predicates: # 断言
- Path=/th/** # 断言,路径相匹配进行路由
GateWay还提供了和Zuul类似的自动路由规则,具体配置如下:
discovery.locator.enabled: true #这个配置默认为false,但是如果为true,就是开启了通过serviceId转发到具体的服务实例.“localhost:9999/ServiceID/th/**”
在配置好这些以后,我们可以直接通过服务名称来进行访问Nacos中注册的服务和对应的接口
这个位置我们为了测试可以启动2个微服务9001、9002
GateWay在开启了自动路由以后,还自带负载均衡
server:
port: 9999
spring:
application:
name: cloud-gateway-service
cloud:
nacos:
discovery:
server-addr: localhost:8848
gateway:
discovery:
locator:
enabled: true #是否与服务发现组件进行结合,通过serviceId转发到具体的服务实例.默认为false,设为true便开启通过服务中心的自动根据 serviceId 创建路由的功能.
9002和9001保持一致,Controller保持一致,负载均衡测试
package com.tianhao.cloudalibabanacos9002.controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/th")
public class DemoController {
@Value("${server.port}")
private String serverPort;
@GetMapping(value = "/get")
public String getServerPort(){
return "库存-1:"+serverPort;
}
@GetMapping(value = "custom")
public String customTest(){
return "Test the gateway configuration class~~custom";
}
}
测试结果:


手动负载均衡
在以上的配置中,其实是有问题的,The problem is that the current service name is exposed,And too flexible,So if you want to solve it,In fact, manual configuration is possible.
具体配置如下:
server:
port: 9999
spring:
application:
name: cloud-gateway-service
cloud:
nacos:
discovery:
server-addr: localhost:8848
gateway:
discovery:
locator:
enabled: true #开启自动路由功能(此时可以关闭)
routes: # 路由
- id: nacos-provider #路由ID,没有固定要求,但是要保证唯一,建议配合服务名
uri: lb://nacos-provider # 匹配提供服务的路由地址
predicates: # 断言
- Path=/th/**
测试
我们现在开启9001/9002两个服务和9999网关服务,然后此时我们可以通过网关去访问:http://localhost:9999/th/get


先自我介绍一下,小编13年上师交大毕业,曾经在小公司待过,去过华为OPPO等大厂,18年进入阿里,直到现在.深知大多数初中级java工程师,想要升技能,往往是需要自己摸索成长或是报班学习,但对于培训机构动则近万元的学费,着实压力不小.自己不成体系的自学效率很低又漫长,而且容易碰到天花板技术停止不前.因此我收集了一份《java开发全套学习资料》送给大家,初衷也很简单,就是希望帮助到想自学又不知道该从何学起的朋友,同时减轻大家的负担.添加下方名片,即可获取全套学习资料哦
