- 方法详细资料
  - getCodes
```
@Nullable
String[] getCodes()
```
    Return the codes to be used to resolve this message, in the order that they should get tried. The last code will therefore be the default one.
    返回:
    a String array of codes which are associated with this message
  - getArguments
```
@Nullable
default Object[] getArguments()
```
    Return the array of arguments to be used to resolve this message.
    The default implementation simply returns null.
    返回:
    an array of objects to be used as parameters to replace placeholders within the message text

  - 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
