setAlwaysUseMessageFormat

public void setAlwaysUseMessageFormat(boolean alwaysUseMessageFormat)

Set whether to always apply the MessageFormat rules, parsing even messages without arguments.

Default is "false": Messages without arguments are by default returned as-is, without parsing them through MessageFormat. Set this to "true" to enforce MessageFormat for all messages, expecting all message texts to be written with MessageFormat escaping.

For example, MessageFormat expects a single quote to be escaped as "''". If your message texts are all written with such escaping, even when not defining argument placeholders, you need to set this flag to "true". Else, only message texts with actual arguments are supposed to be written with MessageFormat escaping.

isAlwaysUseMessageFormat

protected boolean isAlwaysUseMessageFormat()

Return whether to always apply the MessageFormat rules, parsing even messages without arguments.

formatMessage

protected java.lang.String formatMessage(java.lang.String msg,
                                         java.lang.Object[] args,
                                         java.util.Locale locale)

Format the given message String, using cached MessageFormats. By default invoked for passed-in default messages, to resolve any argument placeholders found in them.

参数:

msg - the message to format

args - array of arguments that will be filled in for params within the message, or null if none.

locale - the Locale used for formatting

返回:

the formatted message (with resolved arguments)

createMessageFormat

protected static java.text.MessageFormat createMessageFormat(java.lang.String msg,
                                                             java.util.Locale locale)

Create a MessageFormat for the given message and Locale.

参数:

msg - the message to create a MessageFormat for

locale - the Locale to create a MessageFormat for

返回:

the MessageFormat instance

resolveArguments

protected java.lang.Object[] resolveArguments(java.lang.Object[] args,
                                              java.util.Locale locale)

Template method for resolving argument objects.

The default implementation simply returns the given argument array as-is. Can be overridden in subclasses in order to resolve special argument types.

参数:

args - the original argument array

locale - the Locale to resolve against

返回:

the resolved argument array

renderDefaultMessage

protected java.lang.String renderDefaultMessage(java.lang.String defaultMessage,
                                                java.lang.Object[] args,
                                                java.util.Locale locale)

Render the given default message String. The default message is passed in as specified by the caller and can be rendered into a fully formatted default message shown to the user.

The default implementation passes the String to formatMessage, resolving any argument placeholders found in them. Subclasses may override this method to plug in custom processing of default messages.

参数:

defaultMessage - the passed-in default message String

args - array of arguments that will be filled in for params within the message, or null if none.

locale - the Locale used for formatting

返回:

the rendered default message (with resolved arguments)
