java web results returned unified package type JsonResult

Ado, directly on the code, source code is a network between Mu class teacher shadow wind months to write, I used the direct use.

Package com.yb.entity; 

Import java.util.List; 

Import com.fasterxml.jackson.databind.JsonNode;
 Import com.fasterxml.jackson.databind.ObjectMapper;
