新手参考 /** * 举例net.sf.json.JSONObject.fromObject(obj)生成json报文方式 * 创建请求报文对应demo类 */ public class UnderwritingCustomer extends CustomerBaseInfo{ // 客户联系方式节点 private PartyContactTrans partyContact; public PartyContactTrans getPartyContact() { return partyContact; } public void setPartyContact(PartyContactTrans partyContact) { this.partyContact = partyContact; } /** * （内部类）请求报文 - 客户联系方式节点 * @author caisq */ public static class PartyContactTrans { // 邮箱 private String email;

} return ""; }PS: 1. java内部类详解链接 >>> 2. 例子比较简单，可按示例多重拓展 2. 使用静态内部类，不然实例化时候会报错。 3. 对于特殊格式报文，可单独对内部类toJson，然后合成报文体。 报文模版示例： "customers": [ { "partyId": 1, "person": { "@typeName": "PersonInputFounder", "certiCode": "1231411232", "certiType": 1, "certiEndDate": "9999-12-31", } }, { "partyId": 2, "partyContact": { "email": "[email protected]", "mobile": "18616318161" }, "bankAccounts": [ { "@typeName": "BankAccountInput", "bankAccount": "124241212212", "partyId": 2, "bankCode": "011" } ] } ]—————————————————————加长版分割线—————————————————————————– import net.sf.json.JSONObject;
