InitializingBean
```
public class ConfigurableMimeFileTypeMap
extends FileTypeMap
implements InitializingBean
```
Spring-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.

修饰符和类型	方法	说明
`void`	`afterPropertiesSet()`	Creates the final merged mapping set.
`protected FileTypeMap`	`createFileTypeMap(Resource mappingLocation, String[] mappings)`	Compile a `FileTypeMap` from the mappings in the given mapping file and the given mapping entries.
`String`	`getContentType(File file)`	Delegates to the underlying FileTypeMap.
`String`	`getContentType(String fileName)`	Delegates to the underlying FileTypeMap.
`protected FileTypeMap`	`getFileTypeMap()`	Return the delegate FileTypeMap, compiled from the mappings in the mapping file and the entries in the `mappings` property.
`void`	`setMappingLocation(Resource mappingLocation)`	Specify the `Resource` from which mappings are loaded.
`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`

  - setMappingLocation
```
public void setMappingLocation(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 FileTypeMap getFileTypeMap()
```
    Return the delegate FileTypeMap, compiled from the mappings in the mapping file and the entries in the mappings property.

```
protected FileTypeMap createFileTypeMap(Resource mappingLocation,
                                        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 - MIME type mapping lines (can be null)
    返回:
    the compiled FileTypeMap
    抛出:
    IOException - if resource access failed
