Understanding the Difference Between Struts and Struts2

When it comes to Java web application frameworks, it's important to distinguish between Struts and Struts2. The key difference lies in the architecture and design approach:

• Focus Keyword: Struts vs Struts2
• Struts: Struts is an older version of the framework that follows the Model-View-Controller (MVC) architecture and relies heavily on XML configuration. It has a more complex structure and requires additional configuration for different components.
• Struts2: Struts2, on the other hand, is a newer and improved version that simplifies the framework by using annotations and convention over configuration principles. It offers greater flexibility, easier testing, and enhanced performance compared to its predecessor.

Therefore, if you are considering implementing a Java web application framework, choosing between Struts and Struts2 depends on your project requirements and preferences in terms of simplicity and efficiency.

Difference between Struts and Struts2

Struts and Struts2 are both web application frameworks for building Java-based applications. The main differences between Struts and Struts2 are:

1. Architecture: Struts is based on the Model-View-Controller (MVC) design pattern, while Struts2 is built on a more flexible and powerful architecture.
2. Actions: In Struts, actions are implemented as JavaBeans, whereas in Struts2, actions are simple POJOs (Plain Old Java Objects).
3. Interceptors: Struts2 introduces the concept of interceptors, allowing for more flexible and reusable pre-processing and post-processing of requests.
4. Tag Libraries: Struts2 provides its own tag libraries that offer more functionality and flexibility compared to Struts tag libraries.
5. Configuration: Struts2 configuration is simpler and more annotation-based, making it easier to configure and maintain compared to the XML-based configuration of Struts.

Overall, Struts2 improves upon the shortcomings of Struts and offers a more modern and efficient framework for developing web applications.
