方法详细资料

getCodes

@Nullable
String[] getCodes()

a String array of codes which are associated with this message

getArguments

The default implementation simply returns null.

getDefaultMessage

@Nullable
default String getDefaultMessage()

Return the default message to be used to resolve this message.

The default implementation simply returns null. Note that the default message may be identical to the primary message code (getCodes()), which effectively enforces AbstractMessageSource.setUseCodeAsDefaultMessage(boolean) for this particular message.

返回:

the default message, or null if no default
