Jackson serialization with ObjectMapper in java

Question

I want to serialize the different types of lists by using object mapper, but I do not know how to pass the different types of list objects into object Mapper at a time. T

Answer 1

Simply try:

ObjectMapper objMapper = new ObjectMapper();
String jsonString = objMapper.writeValueAsString(simpleUomList);

Edit according to the comment:

You need to create a class wrapping your two lists and then write it:

public class MyLists {
    private List<TaxCategory> taxCategoryList;
    private List<SimpleUom> simpleUomList;
    // + constructor, getters and setters
}

ObjectMapper objMapper = new ObjectMapper();
MyLists myLists = new MyLists(taxCategoryList, simpleUomList);
String jsonString = objMapper.writeValueAsString(myLists);
