1.maven pom依赖
<dependency>
<groupId>com.alibaba.nacos</groupId>
<artifactId>nacos-spring-context</artifactId>
<version>1.1.1</version>
</dependency>
2.配置nacos初始化配置
@Configuration
@EnableNacosConfig(globalProperties = @NacosProperties(serverAddr = "http://127.0.0.1:8848", username="nacos",password = "nacos"))
@NacosPropertySources({
@NacosPropertySource(dataId = "example", autoRefreshed = true,properties =@NacosProperties(namespace = "") ),
@NacosPropertySource(dataId = "arthas",groupId = "sms-admin",autoRefreshed = true,properties =@NacosProperties(namespace = "015ae736-f567-4633-b6ce-62d2adf0970a") ),
@NacosPropertySource(dataId = "arthas",groupId = "sms-channel",autoRefreshed = true,properties =@NacosProperties(namespace = "f114336d-d549-44bc-bd57-4f41ba5a8347") )
})
public class NacosConfig {
}
3.@NacosValue读取
@NacosValue(value = "${useLocalCache:false}", autoRefreshed = true)
private boolean useLocalCache;
@NacosValue(value = "${testnumber:-1}", autoRefreshed = true)
private Integer testNumber;
4.@NacosConfigurationProperties
@Component
@NacosConfigurationProperties(prefix = "arthas",dataId = "arthas",groupId = "sms-admin",autoRefreshed = true,properties =@NacosProperties(namespace = "015ae736-f567-4633-b6ce-62d2adf0970a"),type = ConfigType.PROPERTIES)
public class DemoProperties {
private String home;
private String agentid;
private String configMap;
}
5.参数发布，动态刷新
@NacosInjected
private ConfigService configService;
@PostMapping
@ResponseBody
public ResponseEntity<String> publish(@RequestParam String dataId,
@RequestParam(defaultValue = "DEFAULT_GROUP") String group,
@RequestParam String content) throws NacosException {
boolean result = configService.publishConfig(dataId, group, content);
if (result) {
return new ResponseEntity<String>("Success", HttpStatus.OK);
}
return new ResponseEntity<String>("Fail", HttpStatus.INTERNAL_SERVER_ERROR);
}
6.本地冷启动
1)在本地缓存目录，手动根据namespace group dateid 的要求，写入指定数据，在程序中能够读取
2)用于一些特殊网络限制冷启动的情况
3)默认{home}/nacos/config/fixed-{host}_{port}-{namespace}_nacos/snapshot-tenant/{namespace}/{group}
/Users/xxx/nacos/config/fixed-127.0.0.1_8848-015ae736-f567-4633-b6ce-62d2adf0970a_nacos/snapshot-tenant/015ae736-f567-4633-b6ce-62d2adf0970a/sms-channel
