serviceA | groupA | groupA@@serviceA

nil | groupA | threw IllegalArgumentException

返回:

'groupName@@serviceName'

getServiceName

public static String getServiceName(String serviceNameWithGroup)

getGroupName

public static String getGroupName(String serviceNameWithGroup)

isServiceNameCompatibilityMode

public static boolean isServiceNameCompatibilityMode(String serviceName)

Check serviceName is compatibility mode or not.

参数:

serviceName - serviceName

if serviceName is compatibility mode, return true

checkServiceNameFormat

public static void checkServiceNameFormat(String combineServiceName)

nil | groupA | groupA@@

nil | nil | @@

返回:

'groupName@@serviceName'
