Nacos常用的API和注解如下:
API:
1. 注册实例:
```
public boolean registerInstance(String serviceName, String ip, int port);
```
2. 更新实例:
```
public boolean updateInstance(String serviceName, String ip, int port, Map<String, String> metadata);
```
3. 删除实例:
```
public boolean removeInstance(String serviceName, String ip, int port);
```
4. 获取所有实例:
```
public List<Instance> getAllInstances(String serviceName);
```
5. 获取健康实例:
```
public List<Instance> getHealthyInstances(String serviceName);
```
6. 订阅服务:
```
public void subscribe(String serviceName, EventListener listener);
```
7. 取消订阅:
```
public void unsubscribe(String serviceName, EventListener listener);
```
8. 发布配置:
```
public boolean publishConfig(String dataId, String group, String content);
```
9. 获取配置:
```
public String getConfig(String dataId, String group, long timeoutMs);
```
10. 删除配置:
```
public boolean removeConfig(String dataId, String group);
```
注解:

String value() default "";
}
```
2. @NacosProperty:
```
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD})
@Documented
public @interface NacosProperty {
String value() default "";
String defaultValue() default "";
}
```
3. @NacosConfigListener:
```
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
@Documented
public @interface NacosConfigListener {
String dataId();
String group() default Constants.DEFAULT_GROUP;
}
```
4. @NacosService:
```
