功能说明
比如前端网页传递过来的数据是id=123&name=zhangsan&age=23
通过工具类，最终能够将键值对赋给User对象
</>复制代码
user{id:123,name:zhangsan,age:23}
实体类
</>复制代码
@Datapublic class User { /** * 昵称 */ private String nickname; /** * 登录名 */ private String account; /** * 电话 */ private String tel;}
工具类
</>复制代码
public class SearchConditionUtil { /** * 调用obj的set方法将searchCondition的值设置到obj中 * * @param obj * @param searchCondition 查询条件 * @param */ public static void initParam(T obj, SearchCondition searchCondition) { if (searchCondition != null) { String searchKey = searchCondition.getSearchKey(); String searchValue = searchCondition.getSearchValue(); if (searchKey != null && searchKey.length() > 0 && searchValue != null && searchValue.length() > 0) { try { Method method = obj.getClass().getMethod("set" + StringUtil.firstLatterUpper(searchKey), String.class); method.invoke(obj, searchValue); } catch (NoSuchMethodException | IllegalAccessException | InvocationTargetException e) { e.printStackTrace(); } } } }}
SearchCondition是用来封装查询数据（key和value）的实体类，具体代码如下：
</>复制代码
@Getter@Setter@ToString@Builder@AllArgsConstructor@NoArgsConstructorpublic class SearchCondition { /** * 条件查询的key */ private String searchKey; /** * 条件查询的value */ private String searchValue;}
测试代码
</>复制代码
public static void main(String[] args) throws Exception { User user = new User(); String searchKey = "tel"; String searchValue = "432423"; SearchCondition searchCondition = new SearchCondition(searchKey, searchValue); initParam(user, searchCondition); System.out.println(user);}
