springboot+nacos使用

依赖

nacos服务发现和注册的依赖

<dependency>
	<groupId>com.alibaba.cloud</groupId>
	<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>

</dependency>

配置

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/wddatabase?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf8&autoReconnect=true&allowMultiQueries=true
    username: root
    password: root
  application:
    name: wd-admin
  profiles:
    active: dev
  cloud:
    nacos:
      config:
        server-addr: 192.168.140.135:8848
        file-extension: properties
        # nacos注册中心地址，注意：结尾不能带斜杠/
      discovery:
         server-addr: 192.168.140.135:8848
         namespace: public

访问nacos地址

http://192.168.140.135:8848/

dataId是由配置信息里的application.name和profiles.active和文件类型组成的

group信息修改

代码示例

@Value("${user.id}")
private String id;
@Value("${user.name}")
private String name;
@Value("${user.age}")
private String age;

/**
 * 测试
 *
 * @return CommonResult
 */
@PostMapping("/")
public CommonResult<String> test() {
	System.out.println(id + name + age);
	return CommonResult.success();
}

修改配置信息

测试运行

自定义配置namespace和服务发现namespace

先把配置配置好

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/wddatabase?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf8&autoReconnect=true&allowMultiQueries=true
    username: root
    password: root
  application:
    name: wd-admin
  profiles:
    active: dev
  cloud:
    nacos:
      config:
        server-addr: 192.168.140.135:8848
        file-extension: properties
        # nacos注册中心地址，注意：结尾不能带斜杠/
        group: admin
        namespace: 7ca03771-8cda-43d1-8880-c4f66077ddf9
      discovery:
        server-addr: 192.168.140.135:8848
        group: admin
        namespace: 7ca03771-8cda-43d1-8880-c4f66077ddf9

命名空间新建  

新建配置，保存

dataId是由application.name和profiles.active组成

再次进行测试，修改成功
