nacos事件监控，监听配置变化

先这样，在这样，然后在那样，就好了~

直接上代码（pom引入）

<!-- https://mvnrepository.com/artifact/com.purgeteam/dynamic-config-spring-boot-starter -->
        <dependency>
            <groupId>com.purgeteam</groupId>
            <artifactId>dynamic-config-spring-boot-starter</artifactId>
            <version>0.1.1.RELEASE</version>
        </dependency>

启动类添加注解

@EnableDynamicConfigEvent

监听类

 
import com.purgeteam.dynamic.config.starter.event.ActionConfigEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.stereotype.Component;
 
import java.util.HashMap;
import java.util.Map;
 
@Component
public class NacosListener implements ApplicationListener<ActionConfigEvent> {
    
    

/** 日志 */
    private static final Logger log = LogManager.getLogger(Nacoslistener.class);

    @Override
    public void onApplicationEvent(ActionConfigEvent environment) {
    
    
        Map<String, HashMap> map = environment.getPropertyMap();
        for (Map.Entry<String, HashMap> entry : map.entrySet()) {
    
    
            String key = entry.getKey();
            Map changeMap = entry.getValue();
            String before = String.valueOf(changeMap.get("before"));
            String after = String.valueOf(changeMap.get("after"));
            if(log.isInfoEnabled()){
    
    
                log.info("配置[key:{}]被改变，改变前before：{}，改变后after：{}",key,before,after);
            }
        }
    }
}

然后启动项目，去修改nacos配置信息就OK了！！！
