Last time I mentioned learning Java programming, servlet is more important, the reasons are as follows: 1.Web uses the HTTP protocol to define a servlet package HTTP protocol for this Java. 2. JSP is also compiled as a servlet when running. 3. Servlet XML configuration file is the control center of the MVC programming mode of the web application. 4. This use XML definition configuration, describes the programming method of the class, is used in a wide field, such as EJB, STRUNT, Spring, Hibernet, and more. 5. Servlet Container is a framework for processing HTTP protocols in Java, which is also widely used in the framework implemented by containers. Such as EJB, Spring, etc.
