## 一、代码 ##

由于篇幅有限，代码见上一篇文章：

[https://blog.csdn.net/forest\_long/article/details/129287941][https_blog.csdn.net_forest_long_article_details_129287941]

分别启动Consul、Service-provider、Service-consumer

## 二、*服务提供者测试*  ##

#### 获取全部列表 ####

[http://localhost:8011/api/user/list][http_localhost_8011_api_user_list]

![198f2220cb13bd7caed6bf31557bec8a.png][]

#### 获取某一值 ####

[http://localhost:8011/api/user/get?id=1][http_localhost_8011_api_user_get_id_1]

![ab949c96704d0d6afe56d365720116e0.png][]

#### 获取服务端口 ####

[http://localhost:8011/api/user/port][http_localhost_8011_api_user_port]

## *二、服务消费者测试* ##

### 1)feign-client方式调用 ###

#### 获取全部列表 ####

[http://localhost:8001/feign-api/user/list][http_localhost_8001_feign-api_user_list]

![5e5e4a83b96c684e9e5f19466b06d759.png][]

#### 获取某一值 ####

[http://localhost:8001/feign-api/user/get?id=1][http_localhost_8001_feign-api_user_get_id_1]

![e21ee67eb3c434e7799c73d74adbffe8.png][]

#### 获取服务端口 ####

[http://localhost:8001/feign-api/user/port][http_localhost_8001_feign-api_user_port]

![fceeff66bc8f7d03aa353516e643c973.png][]

### 2)rest-template方式调用 ###

#### 获取全部列表 ####

[http://localhost:8001/rest-api/user/list][http_localhost_8001_rest-api_user_list]

![2daf1a8190274f0e633bb64c10c3280d.png][]

#### 获取某一值 ####

[http://localhost:8001/rest-api/user/get?id=1][http_localhost_8001_rest-api_user_get_id_1]

![1066b93cdf8a9f9f41f2760071fe60b4.png][]

#### 获取服务端口 ####

[http://localhost:8001/rest-api/user/port][http_localhost_8001_rest-api_user_port]

![712bb257e4433939212ed0e934b627e0.png][]

## *三、负载均衡测试* ##

### 1)多服务提供者启动 ###

java -jar service-provider/target/service-provider-1.0-SNAPSHOT.jar --server.port=8011 
    
    java -jar service-provider/target/service-provider-1.0-SNAPSHOT.jar --server.port=8012
    
    java -jar service-provider/target/service-provider-1.0-SNAPSHOT.jar --server.port=8013

启动后，查看Consul上已经注册了三个service-provider实例服务

### 2)单消费者启动 ###

java -jar service-consumer/target/service-consumer-1.0-SNAPSHOT.jar --server.port=8001

全部启动后，Consul服务列表如下：

### 3)测试负载均衡 ###

访问 [http://localhost:8001/rest-api/user/port][http_localhost_8001_rest-api_user_port]

刷新多次后，发现已经从不同的服务提供者端口提供服务：

第1次

第2次

第3次
