Has always been, we have applied a lot of AOP framework, but for the low-level implementation of AOP is not too much depth, the saying is "know it, do not know why", with the sudden rise of AOP academic discussion, I also opened up their horizons, in-depth understanding of the colorful AOP of the world. Let's take a look at the public definition: Baidu Encyclopedia: In the software industry, AOP is the abbreviation of Aspect oriented programming, whi

configuring the knowledge of AOP.1) Configure the sessionfactory and let spring create the session. Add the following code to the Applicationcontext.xml:We used to create the session with Hibernatesessionfactory.java, now delete it and give it to spring to create. Here, a bean with the session factory class is created with the id "sessionfactory".2) Configure the transaction manager. Add the following code

The key component of the spring framework is the aspect-oriented programming (AOP) framework. Aspect-oriented programming not only breaks down the logic of the program into different parts called the so-called worry. The functionality of an application that spans multiple points is known as crosscutting concerns and these crosscutting concerns are distinguished f

Java EE (Java platform,enterprise Edition) is the enterprise application version of Sun Corporation (Oracle's acquisition of April 20, 2009). This version was formerly known as the Java EE. can help us develop and deploy portable, robust, scalable, and secure server-side Java applications. Built on the

First, elaborated:IoC: We used to write the framework although we have layered, web, business layer, persistence layer. But the relationships between the layers. The coupling is high, when the layer calls the other layer, the object of the class of the new corresponding layer is needed, so we need to change the call of each layer when we make the modification later.The coupling is relatively high and is not conducive to maintenance.And

Because of the test, recently had to touch the Java spring @Scheduled scheduled tasks, it was thought that the configuration of the expression and crontab is exactly the same, did not expect a bit different.in spring , a cron expression has at least 6 or 7 space-delimited time elements.As follows:Example:0 0/5 * * * is triggered every 5 minutes0 15 10 * *?

Similar to @enableasync, you need to set up @enabletransactionmanagement. But note: For method enhancements, we should use the same approach,

There has always been a recent exposure to programming principles or patterns such as the IoC (inversion of control, controlled inversion), DI (Dependency injection, Dependency injection), which is at the heart of the famous Java framework Spring, Struts, and so on. According to this check the Wikipedia entries, and from the library to borrow related books, read

In the near future, instead of doing. NET projects, but using Java as a development language, think about using SPRINGMVC development, because the previous years have used struts1/2+hibernate/ibatis+spring developed projects, so there are some foundation. After seeing some SPRINGMVC's introduction on the net, I made a demo.This demo will be divided into several to introduce, today, first of all, the most ba
