最近项目中需要封装一套复杂的数据模型返回给前端,大致就是一个用户会有多笔订单,每个订单下可能会有多笔保单,
大致的数据模型如下:
为了方面描述,先看一下一个用户下有一条订单,一条订单下有一个保险订单的情况
data: {
" allCommunityTotalContribution ": "全社总盈余贡献单位数",
???
???????" mySumContributionNumber ": "我的保单盈余贡献",
???
???????" orderDetailModel ": [{
???????
“orderNumber”:“订单号”,
???????
" policyDetailModel ":{
???????
“orderNumber”:“订单号”,
“orderEffectiveTime”:“订单生效时间”,
“insuranceName”: 保险名称,
???????
“nameOfAssured”:“被保险人姓名”,
???????
“policyEffectiveState”:“保单生效状态”,
???????
“surplusContributionNumber”:“对应保单盈余贡献单位数”
},
},
]
??},
??
???success: true
此时,需要定义数据库对应的Model
订单层面的list<model>下还有保单层面的model
保单层面下的model定义了保单的相关属性
下面是mapperInterface和mapper.xml文件
自定义一个resultmap,将订单层面的ORDER_NUMBER和该订单号对应的保单号对应,因为是一对多,所以用标签<collection>,,因此在下面的<collection>中需要多定一个属性,用ORDER_NUMBER对应保单
mybati会自动根据自己定义的resultMap去封装参数到model中
返回的参数如下:
{
???"data": {
???????"allCommunityTotalContribution": 10383837.27,
???????"mySumContributionNumber": 404316.24,
"proportionValue":"占全社总数比例小于万分之0.1",
???????"orderDetailModel": [
