enterprise resource planning application

As an enterprise-class Web application, the MVC framework is essential. Spring MVC is currently widely used, and this article describes how to implement the integration of the spring, MyBatis, and spring MVC frameworks in OSGi applications, where the integration of spring MVC is difficult because spring is integrated into OSGi, Each bundle has an isolated applicationcontext, which means that dependency inje

from which the design begins, that is, the layer that influences the layer. In fact, there are only a few reasonable combinations between the business logic layer design and the data access layer design patterns. Design your own data access layer First, it is not recommended that architects and developers write a data access layer from start to end. Many applications, even enterprise-level applications, often use a strong DataSet or activity record o

I recently learned the J2EE enterprise application testing practice book. I think I can still learn a lot. I uploaded the example in the last chapter to csdn to save it as a network hard disk address. The Java resource files used in this example can be downloaded online. The sample is developed using eclipse. If it is transferred to myeclipse, it seems that the J
