记录,动态获取Nacos配置文件的属性

注意:

首先是配置文件不要放在shared-configs,这个配置项的意思是公共配置，放在这个配置项里的配置文件都不会热更新.所有你获取的时候不会改变.需要热更新的配置文件都应该放在extension-configs

        extension-configs:
          - data-id: kaikeba-common-config.yaml
            refresh: true
#        shared-configs:
#          - data-id: kaikeba-common-config.yaml
#              refresh: true

然后再需要的类中使用:@RefreshScope和@value注解就可以了

@RefreshScope
//@ConfigurationProperties(prefix = "spring")
public class OrderController {

    //@Autowired
    //private RestTemplate restTemplate;

    //@Autowired
    //private DiscoveryClient discoveryClient;
    @Value("${cz.config}")
    private String value;

再讲一种方法:导入依赖

     <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <optional>true</optional>
        </dependency>

在类上使用

@ConfigurationProperties(prefix = "spring")表示以spring打头的下面所有属性动态更新

cz:
  config: false
//============================================================
@RestController
//@RefreshScope
@ConfigurationProperties(prefix = "cz")
public class OrderController {

    //@Autowired
    //private RestTemplate restTemplate;

    //@Autowired
    //private DiscoveryClient discoveryClient;

    public String getConfig() {
        return config;
    }

    public void setConfig(String config) {
        this.config = config;
    }

    private String config;
}
