nacos通过@Value动态刷新配置

@Value获取最新值

引入jar包：

<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId><version>2.2.1.RELEASE</version>
</dependency>

引入配置：

spring:application:name: examplecloud:nacos:config:extension-configs[0]:dataId: test.ymlgroup: testrefresh: trueserver-addr:  127.0.0.1:8848namespace: c845e96f-4423-4618-8c26-5e4d510f566aenabled: truerefresh-enabled: true

编写测试类：

@RestController
@RefreshScope
public class TestController {@NacosValue(value = "${test.data}", autoRefreshed = true)private String data;@Value(value = "${test.data}")private String datas;@GetMapping("test")public String test() {return "data ：" + data + ",datas="+datas;}
}
