spring framework core

a lightweight framework or a weight framework? Whether an application is lightweight or heavyweight depends on how many services it uses. the more services you use, the more work containers need to do for common Java objects, which will inevitably affect the application release time or running performance. For spring containers, it provides many services, but t

Before learning framework has been watching the video tutorial, and in all supporting a project source code, followed by the video knocking codes is always very simple, now want to learn more, their own download from the official website manually set up, encountered a lot of problems recorded below.

I. Overview of SPRINGIOC containers IOC container and dependency reversal mode In object-oriented systems, objects encapsulate data and process data, and the dependencies of objects are often reflected in the dependence on data and methods. These dependencies can be done by giving the object's dependency injection to the framework IOC container. He can decouple the code and improve the testability of the code.The implementation of dependency control i

DAO layer uses the Spring JDBC framework, it does not employ the service layer caching technology, so you can use the DAO class to return data from the database. If ORM frameworks such as Hibernate are adopted, because they adopt the technology of service layer caching, in order to get the corresponding data in the database, we need to call the Hibernatetemplate.flush () method after the business method ex

To make JDBC easier to use, Spring defines an abstraction layer on the JDBC API to create a JDBC access framework. As the core of the Spring JDBC Framework, the JDBC template is designed to provide a template approach for different types of JDBC operations. Each template met

SpringFirst, it is an open-source and lightweight framework. The main component of its core container is the Bean Factory (beanfactory). The Bean factory uses the inversion of control (IOC) mode to reduce the coupling between program code and provides a facet-oriented programming (AOP) implementation.As it literally meant, it was the programmer's spring, which gr

However, struts1.x differs greatly from the action model of STRUTS2. The difference between Struts2 and struts1.x, the most obvious is that STRUTS2 is a PULL-MVC architecture.What does that mean? From the developer's point of
