通过反射批量修改属性值set，get方法 Field
需求说明：对接一个系统，对方系统要求每个字段value值加密，加密方法为WebAppAESUtil.encrypt，做之前就想做一个对属性统一操作的一个方法，反射完美的解决了这个问题，类似需求可以这样操作，下面是代码，反射是个好东西
反射工具类
import lombok.extern.slf4j.Slf4j;import java.lang.reflect.AccessibleObject;
import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.List;/*** 类 名: FieldReflection* 描 述:* 作 者: binglong180* 创 建: 2020-07-02 11:23* 邮 箱: binglong172@163.com*/
@Slf4j
public class ReflectionUtils {public static Object FieldReflection(Object oldObj) throws Exception{// 获取对象所有的实例域Field[] fields = oldObj.getClass().getDeclaredFields();// 获得访问私有实例域的权限AccessibleObject.setAccessible(fields, true);for (Field field : fields) {Class<?> type = field.getType();if ("String".equals(type.getSimpleName())) {Object obj = field.get(oldObj);if (obj != null) {String str = obj.toString();field.set(oldObj,WebAppAESUtil.encrypt(str));}}if ("CompanyDTO".equals(type.getSimpleName())){CompanyDTO companyDTO = (CompanyDTO) field.get(oldObj);if (companyDTO != null){companyDTO = (CompanyDTO) FieldReflection(companyDTO);field.set(oldObj,companyDTO);}}if ("List".equals(type.getSimpleName())){List<UserInfoDTO> userInfoDTOList = (List<UserInfoDTO>) field.get(oldObj);if (userInfoDTOList != null && userInfoDTOList.size()>0){List<UserInfoDTO> userInfoList = new ArrayList<>();for (UserInfoDTO item: userInfoDTOList ){if (item != null){item = (UserInfoDTO) FieldReflection(item);userInfoList.add(item);}}field.set(oldObj,userInfoList);}}}return oldObj;}}
1、ServiceDTO 实体类 有List 属性 及CompanyDTO 属性
import lombok.Data;
import org.springframework.beans.factory.annotation.Autowired;import java.util.List;/*** 服务申请接口请求参数字段*/
@Data
public class ServiceDTO {private CompanyDTO nytsydcompanyrequest;//用电企业 必选:trueprivate List<UserInfoDTO> nytsuserrequest;//用户 必选:true nytsuserrequest;//电站信息表 必选:trueprivate NytsPartnetDTO nytsPartnet;private String debUserId;//电e宝用户编号 必选:trueprivate String debSessionId;//会话id 必选:trueprivate String timeStamp;//当前时间的毫秒值 必选:trueprivate String discountType;//优惠类型 必选:true 1固定折扣金额 ，2无折扣（固定电价），3固定优惠金额 ，4先减再乘，5先乘再减。private String status;//状态 必选:true 1正常 2失效private String startTime;//合同开始日期 必选:true 取合同相关信息private String endTime;//合同结束日期 必选:true 取合同相关信息private String billDay;//账单日必选:trueprivate String pvTopPrice;//光伏支付工厂尖电价 必选:true 录入private String pvPeakPrice;//光伏支付工厂峰电价 必选:true 录入private String pvFlatPrice;//光伏支付工厂平电价 必选:true 录入private String pvBottomPrice;//光伏支付工谷尖电价 必选:true 录入private String factoryTopPrice;//工厂支付光伏尖电价 必选:true 无信息，不传递private String factoryPeakPrice;//工厂支付光伏尖电价 必选:true 无信息，不传递private String factoryFlatPrice;//工厂支付光伏尖电价 必选:true 无信息，不传递private String factoryBottomPrice;//工厂支付光伏尖电价 必选:true 无信息，不传递private String fdHouseNumber;//发电户号 必选:true 录入private String preferential;//优惠(减多少) 必选:true 默认初始值：0private String discount;//折扣（打几折乘以多少）private String signTime;//合同签订日期private String image;//合同附件 格式为png转base64private String remark;//合同说明private String lastUpdateTime;//上次更新时间private String ydHouseNumber;//用电户号录入public static ServiceDTO getInitModel(){ServiceDTO serviceVo = new ServiceDTO();serviceVo.setChannelType("03");serviceVo.setStatus("1");serviceVo.setDiscountType("2");serviceVo.setPreferential("0");long timeMillis = System.currentTimeMillis();serviceVo.setTimeStamp(String.valueOf(timeMillis));// String token = cacheStore.getTokenCache().get(current.getId());// serviceVo.setDebSessionId(token);return serviceVo;}
}
CompanyDTO 类
import lombok.Data;/*** 用电企业字段*/
@Data
public class CompanyDTO {private String companyType;//公司类型 必选:true 1发电企业 2用电企业private String companyName;//公司名称 必选:true 取业主名称（录入或合同）private String groupCompany;//集团公司 必选:true 1隶属集团公司，2不是集团公司private String bankName;//开户行名称 必选:trueprivate String orgCode;//组织信用代码(统一社会信用代码) 必选:true 取业主统一社会信用代码（录入或企业认证）private String bankAccount;//银行账户 必选:trueprivate String address;//公司地址private String legalPerson;//公司法人 取业主法人姓名（录入或企业认证）private String telPhone;//公司联系电话private String province;//省 取企业认证申请时录入的相关信息private String city;//市 取企业认证申请时录入的相关信息private String area;//区 取企业认证申请时录入的相关信息}运行后效果
