@Autowired
MongoTemplate mongoTemplate;

void renameFunction() {
    BasicDBObject searchQuery = new BasicDBObject();
    BasicDBObject updateQuery = new BasicDBObject();
    updateQuery.append("$rename",new BasicDBObject().append("field1", "field11").append("field2", "field22"));  
 mongoTemplate.getCollection("Collection_Name").updateMany(searchQuery,updateQuery);
         }
