Web Overview Overview Lightweight enterprise application development is increasingly popular with Java application developers, and the spring Framework is an outstanding representative of lightweight containers. Because of the growing use of spring, there are many applications based on WebSphere Application Server (was) that use the

Spring containerThe spring container helps you manage all bean objects, which are called IOC control reversals. In traditional programs, the generation of objects is done by the developer. In control reversal, the generation of the objects is all given to the framework to complete. The benefit of this is to reduce the dependency of the program.The Bean's life cyc

Spring framework study notes 7: Transaction Management and cases, spring Study Notes Spring provides a mechanism for managing transactions in projects. I have written a simple introduction to the transaction essay: http://www.cnblogs.com/xuyiqing/p/8430214.html There is another Hibernate Transaction Management: http://

The Spring framework is non-invasive, so your code can be completely POJO (plain old java object). You can directly use Junit to complete most unit tests. However, it is difficult to test the integration. At the unit test level, you can mock some dependent objects, but the actual dependent objects are required for integration testing, and these objects are under the control of the

First look at the Spring Framework Configuration example:The server's servlet container uses a Org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader class to read applicatio after the Web. xml file is loaded The Ncontext.xml file, when parsing an AOP tag, invokes the Parsecustomelement method parsing of the Beandefinitionparserdelegate instance, which will look for AOP The handler in nam

Spring is an open source, lightweight, one-stop framework.Spring Core two main parts AOP: Aspect-oriented programming, extended functionality is not a modification of source code implementation IOC: Control inversion, such as a class, there is a method in the class (not a static method), want to invoke the method inside the class, the general method is to create the object (new one), through the new object called method. When using the
