• ReloadableResourceBundleMessageSource

  public ReloadableResourceBundleMessageSource()

方法详细资料

• setFileEncodings

  public void setFileEncodings​(Properties fileEncodings)

  Set per-file charsets to use for parsing properties files.

  Only applies to classic properties files, not to XML files.

  参数:

  fileEncodings - a Properties with filenames as keys and charset names as values. Filenames have to match the basename syntax, with optional locale-specific components: e.g. "WEB-INF/messages" or "WEB-INF/messages_en".

• setConcurrentRefresh

  public void setConcurrentRefresh​(boolean concurrentRefresh)

  Specify whether to allow for concurrent refresh behavior, i.e. one thread locked in a refresh attempt for a specific cached properties file whereas other threads keep returning the old properties for the time being, until the refresh attempt has completed.

  Default is "true": this behavior is new as of Spring Framework 4.1, minimizing contention between threads. If you prefer the old behavior, i.e. to fully block on refresh, switch this flag to "false".

  从以下版本开始:

  4.1

• setPropertiesPersister

  public void setPropertiesPersister​(@Nullable
                                     PropertiesPersister propertiesPersister)

  Set the PropertiesPersister to use for parsing properties files.

  The default is a DefaultPropertiesPersister.

• setResourceLoader

  public void setResourceLoader​(@Nullable
                                ResourceLoader resourceLoader)

  Set the ResourceLoader to use for loading bundle properties files.

  The default is a DefaultResourceLoader. Will get overridden by the ApplicationContext if running in a context, as it implements the ResourceLoaderAware interface. Can be manually overridden when running outside of an ApplicationContext.

  指定者:

  setResourceLoader 在接口中 ResourceLoaderAware

  参数:

  resourceLoader - the ResourceLoader object to be used by this object

• resolveCodeWithoutArguments

  protected String resolveCodeWithoutArguments​(String code,
                                               Locale locale)

  Resolves the given message code as key in the retrieved bundle files, returning the value found in the bundle as-is (without MessageFormat parsing).

  覆盖:

  resolveCodeWithoutArguments 在类中 AbstractMessageSource

  参数:

  code - the code of the message to resolve

  locale - the locale to resolve the code for (subclasses are encouraged to support internationalization)

  返回:

  the message String, or null if not found

• resolveCode

  @Nullable
  protected MessageFormat resolveCode​(String code,
                                      Locale locale)

  Resolves the given message code as key in the retrieved bundle files, using a cached MessageFormat instance per message code.

  指定者:

  resolveCode 在类中 AbstractMessageSource

  参数:

  code - the code of the message to resolve

  locale - the locale to resolve the code for (subclasses are encouraged to support internationalization)

  返回:

  the MessageFormat for the message, or null if not found

• getMergedProperties

  protected ReloadableResourceBundleMessageSource.PropertiesHolder getMergedProperties​(Locale locale)

  Get a PropertiesHolder that contains the actually visible properties for a Locale, after merging all specified resource bundles. Either fetches the holder from the cache or freshly loads it.

  Only used when caching resource bundle contents forever, i.e. with cacheSeconds < 0. Therefore, merged properties are always cached forever.

• calculateAllFilenames

  protected List<String> calculateAllFilenames​(String basename,
                                               Locale locale)

  Calculate all filenames for the given bundle basename and Locale. Will calculate filenames for the given Locale, the system Locale (if applicable), and the default file.

  参数:

  basename - the basename of the bundle

  locale - the locale

  返回:

  the List of filenames to check

• calculateFilenamesForLocale

  protected List<String> calculateFilenamesForLocale​(String basename,
                                                     Locale locale)

  Calculate the filenames for the given bundle basename and Locale, appending language code, country code, and variant code. E.g.: basename "messages", Locale "de_AT_oo" -> "messages_de_AT_OO", "messages_de_AT", "messages_de".

  Follows the rules defined by Locale.toString().

  参数:

  basename - the basename of the bundle

  locale - the locale

  返回:

  the List of filenames to check

• getProperties

  protected ReloadableResourceBundleMessageSource.PropertiesHolder getProperties​(String filename)

  Get a PropertiesHolder for the given filename, either from the cache or freshly loaded.

  参数:

  filename - the bundle filename (basename + Locale)

  返回:

  the current PropertiesHolder for the bundle

• refreshProperties

  protected ReloadableResourceBundleMessageSource.PropertiesHolder refreshProperties​(String filename,
                                                                                     @Nullable

  Refresh the PropertiesHolder for the given bundle filename. The holder can be null if not cached before, or a timed-out cache entry (potentially getting re-validated against the current last-modified timestamp).

  参数:

  filename - the bundle filename (basename + Locale)

  propHolder - the current PropertiesHolder for the bundle

• loadProperties

  protected Properties loadProperties​(Resource resource,
                                      String filename)
                               throws IOException

  Load the properties from the given resource.

  参数:

  resource - the resource to load from

  filename - the original bundle filename (basename + Locale)

  返回:

  the populated Properties instance

  抛出:

  IOException - if properties loading failed

• newProperties

  protected Properties newProperties()

  Template method for creating a plain new Properties instance. The default implementation simply calls Properties().

  Allows for returning a custom Properties extension in subclasses. Overriding methods should just instantiate a custom Properties subclass, with no further initialization or population to be performed at that point.

  返回:

  a plain Properties instance

  从以下版本开始:

  4.2

• clearCache

  public void clearCache()

  Clear the resource bundle cache. Subsequent resolve calls will lead to reloading of the properties files.

• clearCacheIncludingAncestors

  public void clearCacheIncludingAncestors()

  Clear the resource bundle caches of this MessageSource and all its ancestors.
