测试
public static void main(String[] args) {
User sourceS = new User(); // 第一个对象
User targetS = new User(); // 第二个User对象
sourceS.setSex("1");
sourceS.setcName("张三");
targetS.setSex("2");
targetS.setcName("李四");
targetS.setAge(24);
targetS.setSalary("18888");
System.out.pringln(CombineBeansUtil.combineSydwCore(sourceS, targetS));
