JarCastingmicroBean™ Jackson CDI Integration
The microBean™ Jackson CDI Integration project provides a CDI portable extension that allows ObjectMapper instances to be injected in your CDI-based application.
Installation
Declare a dependency in your CDI-based Maven project:
<dependency>
<groupId>org.microbean</groupId>
<artifactId>microbean-jackson-cdi</artifactId>
<version>1.0.0</version>
</dependency>
Usage
Inject an ObjectMapper into a CDI bean:
import javax.enterprise.inject.Default;
import javax.inject.Inject;
import com.fasterxml.jackson.databind.ObjectMapper;
// This will be the default ObjectMapper.
@Inject
private ObjectMapper objectMapper;
// This will be the same ObjectMapper as above.
@Inject
@Default
private ObjectMapper defaultObjectMapper;
// This will be another ObjectMapper.
@Inject
@YourQualifierHere
private ObjectMapper specialObjectMapper;
Customization
To customize the ObjectMapper created by the portable extension furnished by this project, observe an ObjectMapper-typed CDI event:
private static final void onDefaultObjectMapperCreation(@Observes final ObjectMapper objectMapperBeingCreated) {
// The ObjectMapper received here is the default one and is in the process of
// being registered in application scope. You may customize it here, but do
// not retain a reference to it. Here is an arbitrary example.
objectMapperBeingCreated.setLocale(java.util.Locale.getDefault());
}
private static final void onQualifiedObjectMapperCreation(@Observes @YourQualifierHere final ObjectMapper yellowObjectManagerBeingCreated) {
// The ObjectMapper received here is the @YourQualifierHere-qualified one from
// the example above and is in the process of being registered in application
// scope. You may customize it here, but do not retain a reference to it.
// Here is an arbitrary example.
yellowObjectMapperBeingCreated.setTimeZone(java.util.TimeZone.getTimeZone("GMT-8"));
}
