public interface CodecConfigurer
```
Defines a common interface for configuring either client or server HTTP message readers and writers. This is used as follows:
- Use ClientCodecConfigurer.create() or ServerCodecConfigurer.create() to create an instance.
- Use defaultCodecs() to customize HTTP message readers or writers registered by default.
- Use customCodecs() to add custom HTTP message readers or writers.
- Use getReaders() and getWriters() to obtain the list of configured HTTP message readers and writers.
HTTP message readers and writers are divided into 3 categories that are ordered as follows:
1. Typed readers and writers that support specific types, e.g. byte[], String.
2. Object readers and writers, e.g. JSON, XML.
3. Catch-all readers or writers, e.g. String with any media type.
Typed and object readers are further sub-divided and ordered as follows:
1. Default HTTP reader and writer registrations.
2. Custom readers and writers.

- 方法详细资料
  - defaultCodecs
```
CodecConfigurer.DefaultCodecs defaultCodecs()
```
    Provides a way to customize or replace HTTP message readers and writers registered by default.
    另请参阅:
    registerDefaults(boolean)
  - customCodecs
```
CodecConfigurer.CustomCodecs customCodecs()
```
    Register custom HTTP message readers or writers in addition to the ones registered by default.
  - registerDefaults
```
void registerDefaults(boolean registerDefaults)
```
    Provides a way to completely turn off registration of default HTTP message readers and writers, and instead rely only on the ones provided via customCodecs().
    By default this is set to "true" in which case default registrations are made; setting this to false disables default registrations.
  - getReaders
```
List<HttpMessageReader<?>> getReaders()
```
    Obtain the configured HTTP message readers.
  - getWriters
```
List<HttpMessageWriter<?>> getWriters()
```
    Obtain the configured HTTP message writers.
  - clone
```
CodecConfigurer clone()
```
    Create a copy of this CodecConfigurer. The returned clone has its own lists of default and custom codecs and generally can be configured independently. Keep in mind however that codec instances (if any are configured) are themselves not cloned.
