This article describes what is restful and what is the implementation of restful. Simply put, REST refers to a set of schema constraints and principles. Applications or designs that meet these constraints and principles are RESTful.AD:What is rest?REST (Representation State

What is the difference between Mybatis # {}and $, Dynamic SQL is one of the powerful features of Mybatis and an important reason for its superiority over other ORM frameworks.

combination of information generated in Mac OS, Linux, and other platforms makes it easy to load XML data into a program, analyze it, and output results in XML format. To make SGML more user-friendly, XML redefined some of sgml's internal values and parameters, removing a large number of rarely used functions. These complex features complicate SGML when designing websites. XML retains the structured functions of SGML, so that website designers can define their own document types. xml also intro

represented by hyperlink. Another important rest principle is the hierarchical system, which means that the component cannot understand components other than the middle layer of its interaction with it. By limiting the system knowledge to a single layer, you can limit the complexity of the entire system and promote the independence of the underlying layer. When the constraints of the rest architecture are used as a whole application, an application
