Given an list of user defined objects or POJO and object may contains the empty values (e.g. null values or collection of size=0), so while converting list of objects to json we do not want to serialize the empty values. We have already discussed about not serializing empty values using setSerializationInclusion. We will use the JsonInclude annotation… Read More »
Given a list of user defined objects or POJO and object may contains the null values. When we are converting list of objects to JSON, we do not want to serialize the null values. We have already discussed about serialization of non-null values using setSerializationInclusion . We will use the JsonInclude annotation Jackson’s ObjectMapper to block serialization of nulls.… Read More »

Given the user defined object or POJO having date field, we would like to serialize the POJO to JSON. During serialization, we would like save date as a timestamp or ISO format. We will use the Jackson’s ObjectMapper to achieve the conversion. We will create Person class and we will perform the following operations with Person class. Convert Person… Read More »
