Project Objective: To
build a prototype of the project architecture using the latest version of the three frameworks (i.e., Struts2, Spring4, and Hibernate4).
Project Architecture Prototype: Struts2 + spring4.0+ Hibernate4.2.4.
Project features: At the same time using Struts2, Spring4, Hibernate4, log4j and other libraries or frameworks, to build a most basic project prototype.

Join Spring

Add Spring required jar Package

Configure the Web. xml file

Join HibernateAdd the jar package required for hibernate

Join the Hibernate.cfg.xml file, where you configure the basic properties of Hibernate

<?xml version= "1.0" encoding= "UTF-8"?> <!

Integration with Spring
Join C3P0 and MySQL driver



New Db.properties

If successful, the test table is automatically generated in the database join Struts2

Add jar Package: If there are duplicate jar packages, you need to delete the lower version.
