目的为更好的理解MVC分层概念与Java代码设计的一些基本理念。场景描述投保流程信息已经保存到数据库，现在将投保信息查询出来交由DMS进行核保。执行步骤1、 将投保信息从数据查询出来。2、 将投保信息组装成DMS能够识别格式（Json）的数据。3、 将组装好的数据提交DMS（接口）。三个步骤关联设计请参考【图一】步骤1详细说明将订单、保单、保单信息、保单保障责任、投保人、被保人、被保人保障责任、配送地址（投保对象之间的关系请参考【图二】）这些对象从数据库查询出来比较简单，根据订单号（orderSerialNumber）去将所有内容都查询出来。首先定义接口_OrderService，将订单对象查询出来，然后从订单对象获取保单对象，依次的取出其它对象。接口代码（接口需实现）：public interface _OrderService()public Order findOrderByPropertiesMap(String orderNumber);步骤2详细说明将Java对象转换成Json格式的数据主要用到JSONObject、JSONArray、和Map、HashMap。部分代码如下：public class AssemblingUnderwritingJson private Order order;private InsurancePolicy insurancePolicy;private InsurancePolicyBasicInfo insurancePolicyBasicInfo;private InsuranceApplicant insuranceApplicant;private List insureds;private Addressee addressee;public AssemblingUnderwritingJson()/* * 有参构造函数，创建该类时将投保对象初始化 */public AssemblingUnderwritingJson(Order order, InsurancePolicy insurancePolicy,InsurancePolicyBasicInfo insurancePolicyBasicInfo,InsuranceApplicant insuranceApplicant,List insureds,Addressee addressee)this.order = order;this.insurancePolicy = insurancePolicy;this.insurancePolicyBasicInfo = insurancePolicyBasicInfo;this.insuranceApplicant = insuranceApplicant;this.insureds = insureds;this.addressee = addressee;public String getUnderwritingJsonstr()JSONObject JsonRes = new JSONObject();/组装基本信息JsonRes = assemblingBaseInfo(JsonRes);/组装投保人信息JsonRes = assemblingApplicant(JsonRes);/组装被保人信息JsonRes = assemblingInsured(JsonRes);/组装保障责任信息JsonRes = assemblingComponent(JsonRes);/组装指定分公司信息JsonRes = assemblingSellingChannel(JsonRes);return JsonRes.toString();private JSONObject assemblingSellingChannel(JSONObject jsonRes) / TODO Auto-generated method stubreturn null;private JSONObject assemblingComponent(JSONObject jsonRes) / TODO Auto-generated method stubreturn null;private JSONObject assemblingInsured(JSONObject jsonRes) / TODO Auto-generated method stubreturn null;private JSONObject assemblingApplicant(JSONObject jsonRes) / TODO Auto-generated method stubreturn null;private JSONObject assemblingBaseInfo(JSONObject jsonRes) / TODO Auto-generated method stubreturn nu
