sofaboot 集成nacos配置中心与注册中心
网上有很多文章关于集成nacos配置中心与注册中心，但是都是基于springboot版本与springcloudalibaba版本，几乎没有关于sofaboot版本的集成文章，所以这里我写一篇集成文章。
前置条件&环境
- springboot:3.4.3
- springcloud: 2023.0.3
- springcloud-alibaba: 2023.0.1.2
- sofaboot: 4.3.0
- nacos-server: 2.4.3
需要自行安装nacos-server，可参考文章：nacos-server
集成nacos配置中心
1.1 添加依赖
<!-- 配置中心 -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>
<!-- 注册中心 -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
<exclusions>
<exclusion>
<artifactId>jsr305</artifactId>
<groupId>com.google.code.findbugs</groupId>
</exclusion>
</exclusions>
</dependency>为了能使nacos-config生效，需要增加以下依赖并创建bootstrap-{active}.yaml
新增依赖
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>创建bootstrap-{active}.yaml文件，其中{active}为当前环境标识，比如dev、test、prod等
server:
port: 8082
spring:
application:
name: accumulate-admin
cloud:
nacos:
username: xxx
password: xxxxxx
# 注册中心
discovery:
server-addr: http://localhost:8848
# 配置中心
config:
server-addr: http://localhost:8848
config:
import:
- nacos:accumulate-admin.yaml?refreshEnabled=true
- nacos:accumulate-common.yaml?refreshEnabled=true
- nacos:accumulate-admin-common.yaml?refreshEnabled=true
- nacos:test-nacos-extension-config.properties?refreshEnabled=true配置文件根据自己的项目自行定义这里只是为了演示
启动项目
启动以后再nacos中动态的更新一下配置（任意配置），然后你会发现控制台一直循环输出：

如果对nacos源码比较了解应该很快的能定位问题，但是对nacos源码不熟悉的话，就需要耐心的查阅资料和debug才能解决这个问题。
下面是一些参考资料：

直接看日志：com.alibaba.nacos.client.Worker
应该是和nacos-client的com.alibaba.nacos.client.config.impl.ClientWorker有关,查看相关源码打断点
在构造器的地方通过一个定时任务去轮询nacos pull配置
public ClientWorker(final ConfigFilterChainManager configFilterChainManager, ServerListManager serverListManager,
final NacosClientProperties properties) throws NacosException {
this.configFilterChainManager = configFilterChainManager;
init(properties);
agent = new ConfigRpcTransportClient(properties, serverListManager);
ScheduledExecutorService executorService = Executors.newScheduledThreadPool(initWorkerThreadCount(properties),
new NameThreadFactory("com.alibaba.nacos.client.Worker"));
agent.setExecutor(executorService);
agent.start();
}
追踪源码发现通过判断MD5是否相同来判断是否需要更新配置，如果MD5相同则不更新配置，如果MD5不同则更新配置 com.alibaba.nacos.client.config.impl.CacheData#checkListenerMd5
void checkListenerMd5() {
for (ManagerListenerWrap wrap : listeners) {
if (!md5.equals(wrap.lastCallMd5)) {
safeNotifyListener(dataId, group, content, type, md5, encryptedDataKey, wrap);
}
}
}猜想一下，我们跟新配置以后，需要将新的MD5值赋值给 CacheData 的md5属性，所以我跟踪源码找到这个代码打上点断
两个catch语句块也要添加断点，然后启动项目更新配置，查看断点：
可以发现是类找不到，所以我们添加上依赖即可：
<!--解决sofa-boot类隔离导致的 classNotFound 的问题-->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
<version>2.12.0</version>
</dependency>启动以后重新测试，可以发现没有问题了。日志只打印一遍并且能走到 listenerWrap.lastCallMd5 = md5; 断点处
自此nacos集成完毕
未知问题：
LoggerFactory.getLogger(ClientWorker.class).info(“ClientWorker log”);
无法答应日志到控制台
