JSP OA Office Automation System Graduation Design

Spring framework was created to address the complexity of software development. Spring utilizes basic JavaBeans to accomplish tasks that were previously only possible with EJB. However, the use of Spring is not limited to server-side development. From the perspectives of simplicity, testability, and loose coupling, the majority of Java applications can benefit from Spring. JSP embeds Java code and dynamic content into static pages, allowing for the dynamic generation of specific content within a static template. JSP introduces XML tags called 'JSP actions' to invoke built-in functions. Additionally, JSP tag libraries can be created and used like standard HTML or XML tags, enhancing functionality and server performance without cross-platform limitations. During runtime, JSP files are converted by their compiler into more primitive Servlet code. The JSP compiler can either compile JSP files into Servlets written in Java code, which are then compiled by the Java compiler into fast-executing binary machine code, or directly compile them into binary code.
