What are the steps to integrate Struts2 and Spring?

The steps for integrating Struts2 and Spring are as follows:

1. Add the relevant dependencies: Include Struts2 and Spring dependencies in the project’s pom.xml file.
2. Configure web.xml: Set up the Struts2 filter and listener in the web.xml file.
3. Setting up struts.xml: Configure Struts2 configurations in struts.xml, such as package scanning paths, interceptors, etc.
4. Create a Spring configuration file: Create a Spring configuration file (such as applicationContext.xml) and set up Spring-related configurations, such as data sources and transaction managers.
5. Set up the Struts2-Spring plugin: Configure the integration plugin for Struts2 and Spring in the Spring configuration file, such as setting up the scanning and injection of Action classes for Struts2 and Spring.
6. Configure Spring AOP proxy: Configure AOP proxy in the Spring configuration file so that Spring’s dependency injection and transaction management functionalities can be used in Struts2 Action classes.
7. Configure the Struts2 Action class: Use Spring annotations, such as @Autowired, to inject beans managed by Spring into the Struts2 Action class.
8. Start project: Begin project and verify successful integration of Struts2 and Spring.

It should be noted that the integration steps between Struts2 and Spring may vary, depending on the project’s requirements and architecture.
