Order类：

package com.test.utilpojo;
    
    import lombok.Data;
    
    @Data
    public class Order {
    
        private String sender;//发信人
        private String addressee;//收信人邮箱,多个收信人之间;号间隔
        private String ccemail;//抄送人邮箱,多个抄送人之间;号间隔
        private String subject;//标题
        private String body;//正文
    //    private int orderid;
    //    private String ordertype;
    //    private int state;
    //    private String statedesc;
    //    private String optrid;
    //    private String createtime;
        //图片list
    //    private List<String> listimg = new ArrayList<String>();
    }
