Review Comment:
**Optimization Issue**: Simplification of codec creation logic by directly
initializing GrpcCompositeCodec with necessary parameters instead of managing
separate codec instances. <br> **Fix**: Refactor the codec creation to use a
single GrpcCompositeCodec instance, simplifying the overall design and
improving maintainability. <br> **Code Suggestion**:
```
public class GrpcCompositeCodec implements HttpMessageCodec {
private final URL url;
private final FrameworkModel frameworkModel;
private final String mediaType;
private PackableMethod packableMethod;
public GrpcCompositeCodec(URL url, FrameworkModel frameworkModel,
String mediaType) {
this.url = url;
this.frameworkModel = frameworkModel;
this.mediaType = mediaType;
initialize();
}
private void initialize() {
// Initialization logic here
}
@Override
public void encode(OutputStream outputStream, Object data, Charset
charset) throws EncodeException {
...
}
@Override
public Object decode(InputStream inputStream, Class<?> targetType,
Charset charset) throws DecodeException {
...
}
...
}
```

Review Comment:
**Suggestion**: Remove unused import to clean up the code. <br> **Code
Suggestion**:
```
(Removal, no replacement needed)
