本文主要研究一下nacos address的postCluster
nacos-1.1.3/address/src/main/java/com/alibaba/nacos/address/controller/AddressServerClusterController.java
@RestController
@RequestMapping({AddressServerConstants.ADDRESS_SERVER_REQUEST_URL + "/nodes"})
public class AddressServerClusterController {
@Autowired
private ServiceManager serviceManager;
@Autowired
private AddressServerManager addressServerManager;
@Autowired
private AddressServerGeneratorManager addressServerGeneratorManager;
/**
* @param product Ip list of products to be associated
* @param cluster Ip list of product cluster to be associated
* @param ips will post ip list.
* @return
*/
@RequestMapping(value = "", method = RequestMethod.POST)
public ResponseEntity postCluster(@RequestParam(required = false) String product,
@RequestParam(required = false) String cluster,
@RequestParam(name = "ips") String ips) {
//1. prepare the storage name for product and cluster
String productName = addressServerGeneratorManager.generateProductName(product);
String clusterName = addressServerManager.getDefaultClusterNameIfEmpty(cluster);
//2. prepare the response name for product and cluster to client
String rawProductName = addressServerManager.getRawProductName(product);
String rawClusterName = addressServerManager.getRawClusterName(cluster);
Loggers.addressLogger.info("put cluster node,the cluster name is " + cluster + "; the product name=" + product + "; the ip list=" + ips);
ResponseEntity responseEntity;
try {
String serviceName = addressServerGeneratorManager.generateNacosServiceName(productName);
Cluster clusterObj = new Cluster();
clusterObj.setName(clusterName);
clusterObj.setHealthChecker(new AbstractHealthChecker.None());
serviceManager.createServiceIfAbsent(Constants.DEFAULT_NAMESPACE_ID, serviceName, false, clusterObj);
String[] ipArray = addressServerManager.splitIps(ips);
String checkResult = AddressServerParamCheckUtil.checkIps(ipArray);
if (AddressServerParamCheckUtil.CHECK_OK.equals(checkResult)) {
List instanceList = addressServerGeneratorManager.generateInstancesByIps(serviceName, rawProductName, clusterName, ipArray);
for (Instance instance : instanceList) {
serviceManager.registerInstance(Constants.DEFAULT_NAMESPACE_ID, serviceName, instance);
}
responseEntity = ResponseEntity.ok("product=" + rawProductName + ",cluster=" + rawClusterName + "; put success with size=" + instanceList.size());
} else {
responseEntity = ResponseEntity.status(HttpStatus.BAD_REQUEST).body(checkResult);
}
} catch (Exception e) {
responseEntity = ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
}
return responseEntity;
}
//......
} postCluster方法接收product、cluster、ips参数；其中productName通过addressServerGeneratorManager.generateProductName(product)生成；clusterName通过addressServerManager.getDefaultClusterNameIfEmpty(cluster)生成
之后通过通过addressServerGeneratorManager.generateNacosServiceName(productName)生成serviceName，然后通过serviceManager.createServiceIfAbsent创建service
之后校验下ip地址，校验通过的话，会通过addressServerGeneratorManager.generateInstancesByIps(serviceName, rawProductName, clusterName, ipArray)生成instanceList，然后遍历instanceList执行naming模块中的serviceManager的registerInstance方法
nacos-1.1.3/address/src/main/java/com/alibaba/nacos/address/component/AddressServerGeneratorManager.java
@Component
public class AddressServerGeneratorManager {
public String generateProductName(String name) {
if (StringUtils.isBlank(name) || AddressServerConstants.DEFAULT_PRODUCT.equals(name)) {
return AddressServerConstants.ALIWARE_NACOS_DEFAULT_PRODUCT_NAME;
}
return String.format(AddressServerConstants.ALIWARE_NACOS_PRODUCT_DOM_TEMPLATE, name);
}
/**
* @param rawServiceName the raw service name will not contains the {@Constans.DEFAULT_GROUP}
* @return the nacos service name
*/
public String generateNacosServiceName(String rawServiceName) {
if (rawServiceName.indexOf(Constants.DEFAULT_GROUP) != -1) {
return rawServiceName;
}
return Constants.DEFAULT_GROUP + AddressServerConstants.GROUP_SERVICE_NAME_SEP + rawServiceName;
}
public List generateInstancesByIps(String serviceName, String rawProductName, String clusterName, String[] ipArray) {
if (StringUtils.isEmpty(serviceName)
|| StringUtils.isEmpty(clusterName)
|| ipArray == null || ipArray.length == 0) {
return Collections.emptyList();
}
List instanceList = new ArrayList<>(ipArray.length);
for (String ip : ipArray) {
String[] ipAndPort = generateIpAndPort(ip);
Instance instance = new Instance();
instance.setIp(ipAndPort[0]);
instance.setPort(Integer.valueOf(ipAndPort[1]));
instance.setClusterName(clusterName);
instance.setServiceName(serviceName);
instance.setTenant(Constants.DEFAULT_NAMESPACE_ID);
instance.setApp(rawProductName);
instance.setEphemeral(false);
instanceList.add(instance);
}
return instanceList;
}
//......
} AddressServerGeneratorManager的generateProductName方法对于name为空或者是nacos的，返回nacos.as.default，否则返回nacos.as.前缀加name
generateNacosServiceName会返回DEFAULT_GROUP@@加rawServiceName，默认rawServiceName是不包含DEFAULT_GROUP的
generateInstancesByIps方法遍历ipArray，挨个创建instance，注意这里设置了ephemeral为false
nacos-1.1.3/address/src/main/java/com/alibaba/nacos/address/component/AddressServerManager.java
@Component
public class AddressServerManager {
public String getRawProductName(String name) {
if (StringUtils.isBlank(name) || AddressServerConstants.DEFAULT_PRODUCT.equals(name)) {
return AddressServerConstants.DEFAULT_PRODUCT;
}
return name;
}
public String getRawClusterName(String name) {
return getDefaultClusterNameIfEmpty(name);
}
public String getDefaultClusterNameIfEmpty(String name) {
if (StringUtils.isEmpty(name) || AddressServerConstants.DEFAULT_GET_CLUSTER.equals(name)) {
return AddressServerConstants.DEFAULT_GET_CLUSTER;
}
return name;
}
public String[] splitIps(String ips) {
if (StringUtils.isBlank(ips)) {
return new String[0];
}
return ips.split(AddressServerConstants.MULTI_IPS_SEPARATOR);
}
//......
}getRawProductName方法对于name为空或者是name已经是nacos的返回nacos，否则返回原值；getRawClusterName内部调用的是getDefaultClusterNameIfEmpty方法，它对于name是空或者name已经是serverlist的返回serverlist，否则返回原值；splitIps方法根据AddressServerConstants.MULTI_IPS_SEPARATOR来分割字符串为数组
postCluster方法接收product、cluster、ips参数；其中productName通过addressServerGeneratorManager.generateProductName(product)生成；clusterName通过addressServerManager.getDefaultClusterNameIfEmpty(cluster)生成
之后通过通过addressServerGeneratorManager.generateNacosServiceName(productName)生成serviceName，然后通过serviceManager.createServiceIfAbsent创建service
之后校验下ip地址，校验通过的话，会通过addressServerGeneratorManager.generateInstancesByIps(serviceName, rawProductName, clusterName, ipArray)生成instanceList，然后遍历instanceList执行naming模块中的serviceManager的registerInstance方法
