springboot中nacos动态路由
什么都不说了，springboot-nacos 不懂得的下面自行学习啦我直接贴下代码！！！！！！！！！！！！！！！！！！！！！！！！！
首先。。。
我自己有个服务器。在无聊之时写的代码，主要是通过网关来调用接口所以有了下面的代码。
1.作为一个动态路由维护管理的类
@Service
public class DynamicRouteServiceImpl implements ApplicationEventPublisherAware {
/**
*
*/
@Autowired
private RouteDefinitionWriter routeDefinitionWriter;
private ApplicationEventPublisher publisher;
/**
* 增加路由
* @param definition
* @return
*/
public String add(RouteDefinition definition) {
routeDefinitionWriter.save(Mono.just(definition)).subscribe();
this.publisher.publishEvent(new RefreshRoutesEvent(this));
return "success";
}
/**
* 更新路由
* @param definition
* @return
*/
public String update(RouteDefinition definition) {
try {
this.routeDefinitionWriter.delete(Mono.just(definition.getId()));
} catch (Exception e) {
return "update fail,not find route routeId: "+definition.getId();
}
try {
routeDefinitionWriter.save(Mono.just(definition)).subscribe();
this.publisher.publishEvent(new RefreshRoutesEvent(this));
return "success";
} catch (Exception e) {
return "update route fail";
}
}
/**
* 删除路由
* @param id
* @return
*/
public String delete(String id) {
try {
this.routeDefinitionWriter.delete(Mono.just(id));
return "delete success";
} catch (Exception e) {
e.printStackTrace();
return "delete fail";
}
}
@Override
public void setApplicationEventPublisher(ApplicationEventPublisher applicationEventPublisher) {
this.publisher = applicationEventPublisher;
}
2.基于Nacos动态配置路由服务
@Component
public class DynamicRouteServiceImplByNacos implements CommandLineRunner {
private static final Logger logger = LoggerFactory.getLogger(DynamicRouteServiceImplByNacos.class);
@Autowired
private DynamicRouteServiceImpl dynamicRouteService;
@Value("${spring.cloud.nacos.discovery.server-addr}")
private String address;
@Value("${config.dataId}")
private String dataId;
@Value("${config.groupId}")
private String groupId;
@Value("${config.timeout}")
private Long timeout;
/* @Value("${config.ignore}")
private String ignore;*/
/**
* 监听Nacos Server下发的动态路由配置
*/
public void dynamicRouteByNacosListener() {
try {
ConfigService configService = NacosFactory.createConfigService(address);
configService.addListener(dataId, groupId, new Listener() {
@Override
public void receiveConfigInfo(String configInfo) {
try {
logger.info("================Nacos 配置中心路由配置信息已修改================\n" + configInfo + "\n\n");
List<RouteDefinition> list = JSON.parseArray(configInfo, RouteDefinition.class);
list.forEach(definition -> {
dynamicRouteService.update(definition);
});
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public Executor getExecutor() {
return null;
}
});
/*configService.addListener(ignore, groupId, new Listener() {
@Override
public void receiveConfigInfo(String configInfo) {
try {
logger.info("================Nacos 配置中心忽略URL配置已修改================\n" + configInfo + "\n\n");
logger.info("\n" + configInfo + "\n\n");
List<String> ignoreList = JSON.parseArray(configInfo, String.class);
IgnoreRouteConfig.setIgnoreRouteArr(ignoreList);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public Executor getExecutor() {
return null;
}
});*/
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void run(String... args) throws Exception {
dynamicRouteByNacosListener();
}
}
3.yml配置
4. nacos网关配置
5.最后:我建的是父子工程两个服务发到服务器后
注意注意注意!!!：一定要开启防火墙，登上阿里云自己的服务增加端口,然后再linux中也要增加端口
linux防火墙相关命令
删除 firewall-cmd --zone= public --remove-port=80/tcp --permanent
开放 firewall-cmd --zone=public --add-port=1935/tcp --permanent
查看状态 systemctl status firewalld
启动 systemctl start firewalld
查看已开启端口 firewall-cmd --list-ports
重启 firewall-cmd --reload
yml配置文件中 有一个这个端口 这个也要在阿里云上面还有服务器开启
这个就是接口访问时的网关端口号
ok,这篇文章就到了，记录生活。记录技术，希望帮到各位，拜拜！
