cn.taketoday.context.support.mail.javamail.ConfigurableMimeFileTypeMap
所有已实现的接口:
InitializingBean
public class ConfigurableMimeFileTypeMap extends jakarta.activation.FileTypeMap implements InitializingBean
Framework-configurable FileTypeMap implementation that will read MIME type to file extension mappings from a standard JavaMail MIME type mapping file, using a standard MimetypesFileTypeMap underneath.

The mapping file should be in the following format, as specified by the Java Activation Framework: 

 # map text/html to .htm and .html files
 text/html  html htm HTML HTM
Lines starting with # are treated as comments and are ignored. All other lines are treated as mappings. Each mapping line should contain the MIME type as the first entry and then each file extension to map to that MIME type as subsequent entries. Each entry is separated by spaces or tabs.

By default, the mappings in the mime.types file located in the same package as this class are used, which cover many common file extensions (in contrast to the out-of-the-box mappings in activation.jar). This can be overridden using the mappingLocation property.

Additional mappings can be added via the mappings bean property, as lines that follow the mime.types file format.

    • setMappingLocation

      public void setMappingLocation(cn.taketoday.core.io.Resource mappingLocation)
      Specify the Resource from which mappings are loaded.

      Needs to follow the mime.types file format, as specified by the Java Activation Framework, containing lines such as:
      text/html html htm HTML HTM

    • setMappings

      public void setMappings(String... mappings)
      Specify additional MIME type mappings as lines that follow the mime.types file format, as specified by the Java Activation Framework. For example:
      text/html html htm HTML HTM

    • afterPropertiesSet

      public void afterPropertiesSet()
      Creates the final merged mapping set.
      指定者:
      afterPropertiesSet 在接口中 InitializingBean

    • getFileTypeMap

      protected final jakarta.activation.FileTypeMap getFileTypeMap()
      Return the delegate FileTypeMap, compiled from the mappings in the mapping file and the entries in the mappings property.

    • createFileTypeMap

      protected jakarta.activation.FileTypeMap createFileTypeMap(@Nullable cn.taketoday.core.io.Resource mappingLocation, @Nullable String[] mappings) throws IOException
      Compile a FileTypeMap from the mappings in the given mapping file and the given mapping entries.

      The default implementation creates an Activation Framework MimetypesFileTypeMap, passing in an InputStream from the mapping resource (if any) and registering the mapping lines programmatically.

      参数:
      mappingLocation - a mime.types mapping resource (can be null)
      mappings - an array of MIME type mapping lines (can be null)
      返回:
      the compiled FileTypeMap
      抛出:
      IOException - if resource access failed
