Class JsonMapperResolver

java.lang.Object

org.mule.config.transformer.AbstractAnnotatedTransformerArgumentResolver

org.mule.module.json.transformers.JsonMapperResolver

All Implemented Interfaces:

Disposable, TransformerArgumentResolver

public class JsonMapperResolver
extends AbstractAnnotatedTransformerArgumentResolver

This resolver is used by the transform engine to inject a ObjectMapper into a method that requires it. A shared ObjectMapper context can be created for the application and stored in the registry, this will get injected into any transform methods that add ObjectMapper to the method signature.

If there is no shared Object Mapper one will be created for the transformer using the return type as the Json root element.

Since:

3.0

Method Detail

getArgumentClass

protected Class<?> getArgumentClass()

The object type that this resolver will discover or create

Specified by:

getArgumentClass in class AbstractAnnotatedTransformerArgumentResolver

Returns:

The object type that this resolver will discover or create

createArgument

protected Object createArgument(Class<?> annotatedType,
                    MuleContext context)
                         throws Exception

If the resolver cannot locate the required object of type AbstractAnnotatedTransformerArgumentResolver.getArgumentClass() this method will be invoked an instance of the object.

Specified by:

createArgument in class AbstractAnnotatedTransformerArgumentResolver

Parameters:

annotatedType - the annotated object that was matched

context - the current Mule context.

Returns:

a new instance of the object being resolved. This method may also retain a shared instance and possible add configuration to the instance based on this invocation

Throws:

Exception - if the object cannot be created

getAnnotationsPackageName

protected String getAnnotationsPackageName()

This resolver scans a class for annotations in this package. Note this behaviour can be changed by overloading the AbstractAnnotatedTransformerArgumentResolver.findAnnotation(Class) method and search based on your own criteria

Specified by:

getAnnotationsPackageName in class AbstractAnnotatedTransformerArgumentResolver

Returns:

the package of the annotation(s) to scan for
