JEST Client is not working - elasticsearch

Question

I have been stuck with this from a couple of days, any help will be highly appreciable.
How actually we retrieve the documents from the result object of Jest client
I am using the following below code
List<Hit<Part,Void>> hits = searchresult.getHits(Part.class);
for (SearchResult.Hit<Part,Void> hit : hits) {
Here in Part PPOJO class I have a variable attributes
private Object attributes;
Here is the mapping of the attributes field, it is of object type.
"attributes": {
"properties": {
"AttrCatgId": {
"type": "long"
},
"AttrCatgText": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"AttrText": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"AttributeId": {
"type": "long"
}
}
}
Now when I'm retrieving the documents from the result object, it's giving me the values in double format ( .0 is appending by default)
{AttrText=3/4 TON, AttrCatgText=LOAD RATING, AttrCatgId=3.0, AttributeId=11.0}
How to get the AttrText=3/4 TON, AttrCatgText=LOAD RATING, AttrCatgId=3, AttributeId=11 Values in this format.
Thanks for your help in advance.
