publie Object getaddress(){

List<MemberAddress> memberAddressList = new ArrayList<MemberAddress>();
try {
// 通过memberId查询用户所有地址
memberAddressList = memberAddressService.getByMemberId(member.getId());
} catch (Exception e) {
return new APIResult(GlobalConstantsUtil.GENERAL_ERROR, "获取字段失败");
}
// 若memberAddressList集合为空，返回为空
if (memberAddressList == null || memberAddressList.size() == 0) {
return APIResult.createSuccess();
}
// 创建MemberAddressVO3集合
List<MemberAddressVO3> list = new ArrayList<MemberAddressVO3>();
// 遍历MemberAddress，将其值赋予MemberAddressVO3对象
for (int i = 0; i < memberAddressList.size(); i++) {
MemberAddress memberAddress = memberAddressList.get(i);
MemberAddressVO3 memberAddressVO3 = new MemberAddressVO3(); //新创建对象（在循环中）

memberAddressVO3.setMemberAddressId(memberAddress.getId());
memberAddressVO3.setAddressStatus(memberAddress.getAddressStatus());

}
// 将获得的MemberAddressVO3对象添加至MemberAddressVO3的list集合中
list.add(memberAddressVO3);
}
