- org.springframework.context.support.MessageSourceSupport
- - org.springframework.context.support.DelegatingMessageSource

所有已实现的接口:
HierarchicalMessageSource, MessageSource
```
public class DelegatingMessageSource
extends MessageSourceSupport
implements HierarchicalMessageSource
```
Empty MessageSource that delegates all calls to the parent MessageSource. If no parent is available, it simply won't resolve any message.
Used as placeholder by AbstractApplicationContext, if the context doesn't define its own MessageSource. Not intended for direct use in applications.

    从接口复制的说明: HierarchicalMessageSource
    Set the parent that will be used to try to resolve messages that this object can't resolve.
    指定者:
    setParentMessageSource 在接口中 HierarchicalMessageSource
    参数:
    parent - the parent MessageSource that will be used to resolve messages that this object can't resolve. May be null, in which case no further resolution is possible.
  - getParentMessageSource
```
public MessageSource getParentMessageSource()
```
    从接口复制的说明: HierarchicalMessageSource
    Return the parent of this MessageSource, or null if none.
    指定者:
    getParentMessageSource 在接口中 HierarchicalMessageSource
  - getMessage
```
public String getMessage(String code,
                         Object[] args,
                         String defaultMessage,
                         Locale locale)
```
    从接口复制的说明: MessageSource
    Try to resolve the message. Return default message if no message was found.
    指定者:
    getMessage 在接口中 MessageSource
    参数:
    code - the message code to look up, e.g. 'calculator.noRateSet'. MessageSource users are encouraged to base message names on qualified class or package names, avoiding potential conflicts and ensuring maximum clarity.
    args - an array of arguments that will be filled in for params within the message (params look like "{0}", "{1,date}", "{2,time}" within a message), or null if none
    defaultMessage - a default message to return if the lookup fails
    locale - the locale in which to do the lookup
    返回:
    the resolved message if the lookup was successful, otherwise the default message passed as a parameter (which may be null)

                  throws NoSuchMessageException
```
    从接口复制的说明: MessageSource
    Try to resolve the message. Treat as an error if the message can't be found.
    指定者:
    getMessage 在接口中 MessageSource
    参数:
    code - the message code to look up, e.g. 'calculator.noRateSet'. MessageSource users are encouraged to base message names on qualified class or package names, avoiding potential conflicts and ensuring maximum clarity.
    args - an array of arguments that will be filled in for params within the message (params look like "{0}", "{1,date}", "{2,time}" within a message), or null if none
    locale - the locale in which to do the lookup
    返回:
    the resolved message (never null)
    抛出:
    NoSuchMessageException - if no corresponding message was found
    另请参阅:
    MessageSource.getMessage(MessageSourceResolvable, Locale), MessageFormat
  - getMessage
```
public String getMessage(MessageSourceResolvable resolvable,
                         Locale locale)
                  throws NoSuchMessageException
```
    从接口复制的说明: MessageSource
    Try to resolve the message using all the attributes contained within the MessageSourceResolvable argument that was passed in.
    NOTE: We must throw a NoSuchMessageException on this method since at the time of calling this method we aren't able to determine if the defaultMessage property of the resolvable is null or not.
    指定者:
    getMessage 在接口中 MessageSource
    参数:
    resolvable - the value object storing attributes required to resolve a message (may include a default message)
    locale - the locale in which to do the lookup
    返回:
    the resolved message (never null since even a MessageSourceResolvable-provided default message needs to be non-null)
    抛出:
    NoSuchMessageException - if no corresponding message was found (and no default message was provided by the MessageSourceResolvable)
