一般CURD在MODEL做
S层做一些复杂的事情
单个实体的CRUD是放在DAO里做的,Service层再调用这些CRUD方法。
普通的就不需要业务层了,用 Rails 通用的做法就行了。
可以参考下InitPHP框架的分层说明:
http://initphp.com/3_2.htm
MVC分层是开发比较常用的分层方式,也是比较合理通用的方式.
MVC分层将Web分成三层: 模型层,控制层,视图层.
MVC分层将PHP代码和HTML进行了分离,使项目更加整洁和清晰.
InitPHP默认采用DSCV的分层方式,同样也支持MVC分层,DSCV方式将MVC分层的M层分成DAO和Service层.
使用MVC分层,只需要在Controller中直接调用InitPHP::getDao()的类就能实现.
DSCV分层: Dao(数据层),Service(业务服务层),Controller(控制层),View(视图层)
DSCV分层最大的特点是将MVC的模型层Model分离成Dao数据层和Service服务层.
DSCV分层的好处是让各个层次的职责更加明确,数据层更加专注数据操作(SQL操作,缓存操作),业务服务层更加专注提供控制层通用的函数接口.
Service一般是针对业务的,例如用户类UserService,将提供用户注册,用户信息修改等接口,Service可以让Controller来调用.
Service中获取数据通过Dao来实现,一个复杂的Service会对应多个Dao.

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i.

Java Made Simple: A Beginner's Guide to Programming Power Introduction Java is a powerful programming language used in everything from mobile applications to enterprise-level systems. For beginners, Java's syntax is simple and easy to understand, making it an ideal choice for learning programming. Basic Syntax Java uses a class-based object-oriented programming paradigm. Classes are templates that organize related data and behavior together. Here is a simple Java class example: publicclassPerson{privateStringname;privateintage;

Java is a popular programming language that can be learned by both beginners and experienced developers. This tutorial starts with basic concepts and progresses through advanced topics. After installing the Java Development Kit, you can practice programming by creating a simple "Hello, World!" program. After you understand the code, use the command prompt to compile and run the program, and "Hello, World!" will be output on the console. Learning Java starts your programming journey, and as your mastery deepens, you can create more complex applications.

Capsules are three-dimensional geometric figures, composed of a cylinder and a hemisphere at both ends. The volume of the capsule can be calculated by adding the volume of the cylinder and the volume of the hemisphere at both ends. This tutorial will discuss how to calculate the volume of a given capsule in Java using different methods. Capsule volume formula The formula for capsule volume is as follows: Capsule volume = Cylindrical volume Volume Two hemisphere volume in, r: The radius of the hemisphere. h: The height of the cylinder (excluding the hemisphere). Example 1 enter Radius = 5 units Height = 10 units Output Volume = 1570.8 cubic units explain Calculate volume using formula: Volume = π × r2 × h (4
