copied!<p>You want Jackson to always use your custom JsonSerializer or JsonDeserializer to serialize/deserialize a specific type?</p> <p>I ended up writing a custom Jackson module to let Jackson find serializers and deserializers that are Spring beans. I am using Spring 3.1.2 and Jackson 2.0.6</p> <p>Simplified version:</p> <pre><code>public class MyObjectMapper extends ObjectMapper { @Autowired public MyObjectMapper(ApplicationContext applicationContext) { SpringComponentModule sm = new SpringComponentModule(applicationContext); registerModule(sm); } } </code></pre> <p>Module: </p> <pre><code>public class SpringComponentModule extends Module { private ApplicationContext applicationContext; public SpringComponentModule(ApplicationContext applicationContext) { this.applicationContext = applicationContext; } @Override public String getModuleName() { return "jackson-spring-component"; } @Override public Version version() { return SpringComponentModuleVersion.instance.version(); } @Override public void setupModule(SetupContext context) { context.addSerializers(new SpringComponentSerializers(this.applicationContext)); context.addDeserializers(new SpringComponentDeserializers(this.applicationContext)); } } </code></pre> <p>ComponentSerializer class:</p> <pre><code>public class SpringComponentSerializers extends Serializers.Base { private ApplicationContext applicationContext; public SpringComponentSerializers(ApplicationContext applicationContext) { this.applicationContext = applicationContext; } @Override public JsonSerializer<?> findSerializer(SerializationConfig config, JavaType type, BeanDescription beanDesc) { Class<?> raw = type.getRawClass(); Map<String,JsonSerializer> beanSet = applicationContext.getBeansOfType(JsonSerializer.class); for(String beanName : beanSet.keySet()) { JsonSerializer<?> serializer = beanSet.get(beanName); if(serializer.handledType().isAssignableFrom(raw)) { return serializer; } } return null; } } </code></pre>
