[jira] [Created] (CXF-6588) NPE in providers.getMessageBodyReader
David J. M. Karlsen created CXF-6588:
----------------------------------------
Summary: NPE in providers.getMessageBodyReader
Key: CXF-6588
URL: https://issues.apache.org/jira/browse/CXF-6588
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 3.1.2
Reporter: David J. M. Karlsen
I have this ParamConverter:
{code}
@Provider
@Component
public class JacksonParamConverterProvider
implements ParamConverterProvider
{
private final JsonMapperConfigurator jsonMapperConfigurator;
@Context
private Providers providers;
public JacksonParamConverterProvider()
{
ObjectMapper objectMapper = new ObjectMapper();
this.jsonMapperConfigurator =
new JsonMapperConfigurator( objectMapper, new Annotations[]{ Annotations.JAXB, Annotations.JACKSON } );
}
@Override
public <T> ParamConverter<T> getConverter( Class<T> rawType, Type genericType, Annotation[] annotations )
{
MessageBodyReader<T> messageBodyReader = providers.getMessageBodyReader( rawType,
genericType,
annotations,
MediaType.APPLICATION_JSON_TYPE );
if ( messageBodyReader == null || !messageBodyReader.isReadable( rawType, genericType, annotations, MediaType.APPLICATION_JSON_TYPE ) ) {
return null;
}
if ( canConvert( rawType ) )
{
return new ParamConverter<T>()
{
@Override
public T fromString( String value )
{
ObjectReader objectReader = getObjectMapper().readerFor( rawType );
try
{
return objectReader.readValue( value );
}
catch ( IOException e )
{
throw new ProcessingException( e );
}
}
@Override
public String toString( T value )
{
try
{
return getObjectMapper().writerFor( rawType ).writeValueAsString( value );
}
catch ( JsonProcessingException e )
{
throw new ProcessingException( e );
}
}
};
}
else
{
return null;
}
}
private ObjectMapper getObjectMapper()
{
return jsonMapperConfigurator.getConfiguredMapper();
}
private boolean isNotSimpleType( Class<?> rawType )
{
return ! ( rawType.getPackage().getName().startsWith( "java.lang" ) || ClassUtils.isPrimitiveOrWrapper( rawType ) );
}
private boolean canConvert( Class<?> rawType )
{
return isNotSimpleType( rawType ) && getObjectMapper().canSerialize( rawType );
}
{code}
which will get an NPE when calling getMessageBodyReader:
