这是一个基于Servlet的Java Web应用程序中的ManageCourseController类。它处理/admin/managecoursesUrl的GET请求,通过CoursesService获取课程列表并将其作为属性添加到请求中,然后将请求转发到manage-course.jsp页面。POST请求也会被转发到相同的方法。

public class AddBookServlet extends HttpServlet { private static final long serialVersionUID = 1L
这是一个 Java 类,用于实现添加图书的 Servlet。Servlet 是 Java Web 应用程序中处理 HTTP 请求的组件,可以响应来自客户端的 GET、POST 等请求,并返回相应的响应结果。serialVersionUID 是一个序列化版本号,用于在反序列化时确保类的版本一致性。通常情况下,当类的结构发生变化时,serialVersionUID 也需要相应地进行更新,以保证反序列化时的正确性。
