nacos与spring cloud gateway 一起的使用的时候uri: lb://server-name配置不起用

首先我们将uri配置成本地地址测试服务是否可以调通

yaml 复制代码

spring:
  cloud:
    nacos:
      discovery:
        server-addr: xxx.xxx.xxx.xxx:8848
    gateway:
      routes:
        - id: angular_app
          uri: http://localhost:8082
          predicates:
            - Path=/angular/**
          filters:
            - StripPrefix=1

xxx.xxx.xxx.xxx:8848 切换成你的nacos服务器地址

bash 复制代码

yanghaoyuan@yanghaoyuandeMacBook-Pro ~ % curl http://localhost:8080/angular/users
[{"id":1,"name":"张三","age":23,"email":"[email protected]","isDeleted":0,"createdDate":"2024-05-06T03:43:13","lastModifiedDate":null,"createdBy":"1","lastModifiedBy":null}]%

8080端口是本地gateway的服务端口，上面表明已经可以调通。

yaml 复制代码

spring:
  cloud:
    nacos:
      discovery:
        server-addr: xxx.xxx.xxx.xxx:8848
    gateway:
      routes:
        - id: angular_app
          uri: lb://user-service
          predicates:
            - Path=/angular/**
          filters:
            - StripPrefix=1

换成 lb负载均衡的方式调用调不通，初步判断应该是没有添加lb的依赖包，所以lb的方式无法获取服务列表从而无法转发。

java 复制代码

            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-loadbalancer</artifactId>
                <version>4.0.3</version>
            </dependency>

在pom中添加lb的依赖，重启服务测试

bash 复制代码

yanghaoyuan@yanghaoyuandeMacBook-Pro ~ % curl http://localhost:8080/angular/users
[{"id":1,"name":"张三","age":23,"email":"[email protected]","isDeleted":0,"createdDate":"2024-05-06T03:43:13","lastModifiedDate":null,"createdBy":"1","lastModifiedBy":null}]%

ok，👌已经可以调通，nacos与spring cloud gateway一起使用的时候要注意依赖包。
