一个统一将数据转换为JSON的方法

这是我得方法：

导包：

　　import net.sf.json.JSONArray;
　　import net.sf.json.JSONObject;

public void writeJson(Object obj) {
        HttpServletResponse response = ServletActionContext.getResponse();
        JSONArray jsonArray = JSONArray.fromObject(obj);
        response.setContentType("text/javascript; charset=utf-8"); 
        try {
            response.getWriter().write(jsonArray.toString());
            jsonArray = null;
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    public void writeJsonObject(Object obj) {
        HttpServletResponse response = ServletActionContext.getResponse();
        JSONObject jsonObject = JSONObject.fromObject(obj);
        response.setContentType("text/javascript; charset=utf-8"); 
        try {
            response.getWriter().write(jsonObject.toString());
            jsonObject = null;
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
 

别人的方法：

导包：
import net.sf.json.JSONArray;

public void sendToForwardByList( List<SupplierAchieve> list ) {
        JSONArray jobj = JSONArray.fromObject( list );
        response.setCharacterEncoding( "utf-8" );
        try {
            response.getWriter().write( jobj.toString() );
            jobj = null;
            list = null;
        } catch( IOException e ) {
            e.printStackTrace();
        }
    }
