【springboot】读取本地nacos配置

embedded/2025/1/17 12:35:53/

1.springboot读取服务器上nacos配置会在客户端本地缓存配置。
2.在没有服务器nacos配置的情况下，可以在本地新建一个目录，里面放入配置文件，也可以读到配置。
3.注意不同版本的nacos配置目录默认不一样。请注意nacos和springboot的版本号。
4.当远程连不上服务器的nacos时，可以在本地放个缓存来启动项目。

</project>

2.application.yaml

spring:cloud:nacos:config:# 本地没有这个nacos，随便写的server-addr: 127.0.0.1:8848group: DEFAULT_GROUPfile-extension: yaml

3.启动类

package com.learn;import com.alibaba.nacos.spring.context.annotation.config.NacosPropertySource;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;/*** @date 2024/12/11* @description*/
@SpringBootApplication
@NacosPropertySource(dataId = "application.yaml", autoRefreshed = true)
public class Application {public static void main(String[] args) {SpringApplication.run(Application.class, args);}
}

4.controller类

package com.learn.controller;import com.alibaba.nacos.api.config.annotation.NacosValue;
import org.springframework.web.bind.annotation.*;@RestController
@RequestMapping("/example")
public class ExampleController {@NacosValue("${test.name}")private String name;@GetMapping("/test")public String test() {return name;}
}
