Find first valid IP from local network card

返回:

first valid local IP

findNetworkInterface

public static NetworkInterface findNetworkInterface(NetUtils.NetworkInterfaceChecker networkInterfaceChecker)

Get the suitable NetworkInterface

返回:

If no NetworkInterface is available , return null

从以下版本开始:

first

public static <T> T first(Collection<T> values)

Take the first element from the specified collection

类型参数:

T - the type of element of collection

参数:

values - the collection object

返回:

if found, return the first one, or null

从以下版本开始:

isPreferredNetworkInterface

public static boolean isPreferredNetworkInterface(NetworkInterface networkInterface)

Is preferred NetworkInterface or not

参数:

networkInterface - NetworkInterface

返回:

if the name of the specified NetworkInterface matches the property value from PowerJobDKey.PREFERRED_NETWORK_INTERFACE, return true, or false

splitAddress2IpAndPort

public static org.apache.commons.lang3.tuple.Pair<String,Integer> splitAddress2IpAndPort(String address)
