JSON字串解析成物件

• JSON字串

{
  "mailNo": "12345678",
  "orgCode": "315005"
}

• NameReq 程式碼

public class NameReq {
    private String mailNo; //運單號
    private String orgCode; //機構程式碼

    public String getMailNo() {
        return mailNo;
    }
    public void setMailNo(String mailNo) {
        this.mailNo = mailNo;
    }
    public
 
 String getOrgCode() {
        return orgCode;
    }
    public void setOrgCode(String orgCode) {
        this.orgCode = orgCode;
    }

}

NameReq nameReq = gson.fromJson(body, NameReq.class);

JSON字串解析成集合

• JSON字串

[{
    "monthStartDay": "2018-04-01 00:00:00",
