"通向架构师的道路：探索万能框架Spring(四)"

The journey to becoming an architect (Day 22) - The versatile framework Spring (Part 4) In this segment, we will be exploring the transition of our Struts layer from version 1.3 to Struts 2.x. This switch to Struts 2.0 brings about significant changes to our code and framework, which we will dissect in this discussion. 1. Introduction With our SSH framework established, the focus now shifts towards the replacement of our Struts layer from 1.3 to Struts 2.x. This enhancement involves the incorporation of Struts 2.0, which brings about noticeable modifications to our code and framework. 2. Advantages of Struts 2 The integration of Struts 2 presents several benefits that contribute to the efficiency and robustness of our system. i) Thread Safety: In Struts 2, all variables within methods are inherently thread-safe, unlike the previous Struts 1 framework. ii) Simplified Data Handling: With Struts 2, the need to use "request.setAttribute" to carry values to the page is eliminated. Declaring and setting a variable, such as "studentName" as shown in the code snippet, streamlines the process and reduces the necessity for repetitive operations involving "setAttribute" and "getAttribute" within the request. In summary, the shift to Struts 2.x brings about a heightened level of security and efficiency, enabling smoother data handling and reduced complexities in the framework. As we continue to navigate the path towards becoming an architect, it is essential to embrace and understand the updates and advancements in frameworks such as Struts 2.0. These enhancements not only improve the functionality of our system but also equip us with the knowledge and skills required to drive architectural excellence.
