Class HibernateProxySerializer

java.lang.Object

com.fasterxml.jackson.databind.JsonSerializer<org.hibernate.proxy.HibernateProxy>

com.fasterxml.jackson.datatype.hibernate5.HibernateProxySerializer

All Implemented Interfaces:

com.fasterxml.jackson.databind.jsonFormatVisitors.JsonFormatVisitable, com.fasterxml.jackson.databind.ser.ContextualSerializer

public class HibernateProxySerializer
extends com.fasterxml.jackson.databind.JsonSerializer<org.hibernate.proxy.HibernateProxy>
implements com.fasterxml.jackson.databind.ser.ContextualSerializer

Serializer to use for values proxied using HibernateProxy.

TODO: should try to make this work more like Jackson BeanPropertyWriter, possibly sub-classing it -- it handles much of functionality we need, and has access to more information than value serializers (like this one) have.

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
protected static class	HibernateProxySerializer.ProxyReader Inspects a Hibernate proxy to try and determine the name of the identifier property (Hibernate proxies know the getter of the identifier property because it receives special treatment in the invocation handler).
protected static class	HibernateProxySerializer.ProxySessionReader Hibernate 5.2 broke abi compatibility of org.hibernate.proxy.LazyInitializer.getSession() The api contract changed from org.hibernate.proxy.LazyInitializer.getSession()Lorg.hibernate.engine.spi.SessionImplementor; to org.hibernate.proxy.LazyInitializer.getSession()Lorg.hibernate.engine.spi.SharedSessionContractImplementor On hibernate 5.2 the interface SessionImplementor extends SharedSessionContractImplementor.
