getText

public static String getText(String key,
                             String defaultMessage,
                             List<Object> args,
                             com.opensymphony.xwork2.util.ValueStack stack)

Get a message from the first TextProvider encountered in the stack. If the first TextProvider doesn't provide the message the default message is returned.

The stack is searched if if no TextProvider is found, or the message is not found.

参数：

key - the message key in the resource bundle

defaultMessage - the message to return if not found (evaluated for OGNL)

args - an array args to be used in a MessageFormat message

stack - the value stack to use for finding the text

返回：

the message if found, otherwise the defaultMessage

getText

public static String getText(String key,
                             String defaultMessage,
                             List<Object> args,
                             com.opensymphony.xwork2.util.ValueStack stack,
                             boolean searchStack)

Get a message from the first TextProvider encountered in the stack. If the first TextProvider doesn't provide the message the default message is returned.

The search for a TextProvider is iterative from the root of the stack.

This method was refactored from Text to use a consistent implementation across UIBean components.

参数：

key - the message key in the resource bundle

defaultMessage - the message to return if not found (evaluated for OGNL)

args - an array args to be used in a MessageFormat message

stack - the value stack to use for finding the text

searchStack - search stack for the key

返回：

the message if found, otherwise the defaultMessage
