Issue
I have a map, Map<String, Object> map = new HashMap<>(); I am storing multiple types of data in this map. 1.) Primitive types 2.) User-defined class's object as a value in this map. When I am casting any primitive type value as Object and store in Map, its working fine but not in case of user-defined. While storing user-defined types data in this map, I am getting below error:-
**ERROR [WebExceptionHandler] Error occurred while serving request. Response is as [Response(
description=Type definition error: [simple type, class com.yyz.util.Abc];
nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException:

Can anyone explain why I am getting this error and what is the solution?
@Setter
@Getter
@ToString
@JsonPropertyOrder({ "numRecordsFound", "rowViewCount", "buyingUnitRows" })
public class BuResponse extends Response implements Serializable {
private static final long serialVersionUID = -5269171275831114276L;
private final List<BuRow> buRows = new ArrayList<>();
private long numRecordsFound;
private long rowViewCount;
}
@Getter
@Setter
@ToString
@EqualsAndHashCode(callSuper = false)
@JsonPropertyOrder({ "properties", "children", "positionData" })
public class BuRow extends TreeRow {
private static final long serialVersionUID = -9087386484833636274L;
private List<BuRow> children;
private Map<String, Object> positionData = new HashMap<>();
private Map<String, Object> properties;
public Map<String, Object> getPositionData() {
return positionData;
}
@JsonAnyGetter
public Map<String, Object> getProperties() {
return properties;
}
}
Thanks in advance!
Solution
Make your field(s) / getter(s) -- public
The exception says your Abc class is an empty bean and SerializationFeature.FAIL_ON_EMPTY_BEANS is enabled (by default). For example, this class would be an empty bean for jackson serializer:
public class Abc {
boolean boo;
}
If you had at least one public field, or a public getter, that would avoid the exception:
public class Abc {
public boolean boo;
}
