Add configuration in the configuration file

#NACOS Configuration Center
nacos.config.server-addr=119.22.91.21:8848

Directly injected

Then add annotations to the startup class

@NacosPropertySources(value = {
        @NacosPropertySource(dataId = "consumer-server",autoRefreshed = true),
        @NacosPropertySource(dataId = "provider-dubbo",autoRefreshed = true),
        @NacosPropertySource(dataId = "email",autoRefreshed = true),
        @NacosPropertySource(dataId = "system",autoRefreshed = true),
})

Then inject the parameters directly in the place where the parameters need to be injected;

@NacosValue(value = "${server.port}",autoRefreshed = true)
private String port;

Add the configuration file to the injection of POJO

Configuration sample

port=[email protected]
host=1467
key=aoiZ9812LA82*l1
useAuth=true
user=[email protected]
from=[email protected]

@NacosConfigurationPropertiesannotation

@Data
@Configuration
@NacosConfigurationProperties(dataId = "email",autoRefreshed = true)
public class EmailConfig {
   private String port;
   private String host;
   private String key;
   private boolean useAuth;
   private String user;
   private String from;

   // This kind of configuration can only be said to create a singles bean. In fact, even if the cloud is updated, it will not be updated. There are only many cases that really take effect.
   @Bean(name = "emailConf")
   public EmailConf getConf(){
     return BeanUtil.copyProperties(this,EmailConf.class);
   }

   // So you get newly generated every time, of course you can return this directly to
   public EmailConf getConfs(){
      return BeanUtil.copyProperties(this,EmailConf.class);
   }
}

POJO injection with prefix

@NacosConfigurationProperties+Annotation

email.port=huatian@163.com
email.host=1467
email.key=aoiZ9812LA82*l1
