使用方式：
代码语言：javascript复制@Test
void testCopyProperties() {
LambdaExecutable source =
LambdaHelper.resolve(
(Serializable & Function<LambdaExecutable, String>) LambdaExecutable::getName);
LambdaExecutable target = BeanHelper.copyProperties(source, null);
Assertions.assertNotNull(target);
Assertions.assertEquals(source.getName(), target.getName());
}此处target为null会自动创建，只能copy到同类型，后续会支持不同类型的，尽请期待
目前的源码：
代码语言：javascript复制/**
* 拷贝属性
*
* @param source 源对象
* @param target 目标对象
* @param <T> 对象类型
*/
public static <T> T copyProperties(T source, T target) {
if (Objects.isNull(source)) {
return target;
}
Class<T> clazz = SerFunc.<Class<?>, Class<T>>cast().apply(source.getClass());
AtomicReference<T> targetRef = new AtomicReference<>(target);
if (Objects.isNull(targetRef.get())) {
SerFunc<Class<T>, Constructor<T>> getConstructor = Class::getConstructor;
Constructor<T> constructor = getConstructor.andThen(ReflectHelper::accessible).apply(clazz);
SerFunc<Constructor<T>, T> newInstance = Constructor::newInstance;
targetRef.set(newInstance.apply(constructor));
}
Map<SerFunc<T, Object>, SerBiCons<T, Object>> getterSetterMap =
LambdaHelper.getGetterSetterMap(clazz);
getterSetterMap.forEach(
(getter, setter) -> setter.accept(targetRef.get(), getter.apply(source)));
return targetRef.get();
}
