对象内List数组为空处理成长度为0的list

public static void handlerNullList(Object object) {
try {
Class<? extends Object> clazz = object.getClass();
Method[] declaredMethods = clazz.getDeclaredMethods();
for(Method method : declaredMethods) {
String methodName = method.getName();
Class<?> type = method.getReturnType();
if(methodName.indexOf("get") == 0 && List.class.equals(type)) {
List getList = (List) method.invoke(object, null);
if(getList == null) {
String setMethodName = methodName.replaceFirst("g", "s");
//数组初始化(找到对应set方法，get返回值类型)
Method setMethod = clazz.getDeclaredMethod(setMethodName, List.class);
setMethod.invoke(object, Collections.emptyList());
} else {
if(getList.size() != 0) {
for(Object obj : getList) {
handlerNullList(obj);
}
}
}
}
}
} catch (Exception e) {
throw new RuntimeException(e);
}
