Saya sedang mengerjakan SpringMVC, Hibernate& JSONtetapi saya mendapatkan kesalahan ini.
HTTP Status 500 - Could not write JSON: No serializer found for class org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationConfig.SerializationFeature.FAIL_ON_EMPTY_BEANS) )
Silakan periksa Entitas saya di bawah
