In the Java session, a bull named Rod Johnson found that the initial Java enterprise-level development was in a state of chaos. As a result, it is determined to write a common infrastructure that solves the problem. Because it is convinced that interface-oriented programming can control change to the minimum, but also conducive to expansion and change. As a result, it writes the following interface. In

, specifying the node of the target data through the distributed algorithm.Ehcache Pure Java implementation, slow in memory, can be persisted to the hard disk, the efficiency is higher than memcache, but the cache sharing trouble, the cluster distributed application is inconvenient. If it is a single application or a high-demand application for cache access, use Ehcache. Ehcache also has a cache sharing scheme, but the broadcast cache notification upd

Turn from: http://www.ibm.com/developerworks/cn/webservices/ws-springjava/ Overview As we all know, the Spring framework is a driving factor in the control reversal (IOC) or Dependency injection (DI) pattern, which is implemented through a container based configuration. In the past, Spring allows developers to use xml-based configurations to manage bean dependencies by leveraging application context XML fil

Spring for Java ssh Although I used the C #. NET Language for my internship before graduation, I decided to apply for Java after graduation. Although I do not have a deep understanding of Java as C #, I am only familiar with the basic knowledge, but I still have no worries ··· Although the application experience is rel

Brief introductionaspect-oriented programming (AOP) provides another way to think about the structure of a program, making up for the lack of object-oriented programming (OOP). In addition to classes (classes), AOP provides slices. Cut to the point of concern for modularity, such as transaction management across multiple types and objects. (These attention-point terms are often referred to as crosscutting (crosscutting) concerns.) ） One of the key components of

Spring IntroductionOne of the core issues that spring solves is to shift the dependencies between objects into a configuration file, which is implemented through spring's dependency injection mechanism.Spring Bean Assembly1. The IOC concept and how the IOC operates in the spring container.Ioc:inversion of control, inversion of controls. In

inherits or implements the corresponding classes or interfaces in a normal class, you can get the ApplicationContext object of spring. However, it is important to note that the normal Java class that inherits or implements these abstract classes or interfaces must be configured in the spring's configuration file (that is, the Application-context.xml file), otherwise the obtained ApplicationContext object w

are equivalent, but from the name of the annotation class it is easy to see that the 3 annotations correspond to the persistence layer, the business layer, and the control layer (the WEB layer), respectively. Although there is nothing new about these 3 annotations and @Component, Spring will add special features to them in future releases. Therefore, if a WEB application uses a classic three-tier hierarchy, it is best to annotate the classes in the h

Vs. NET + spring.net + nhib.pdf used in. net. On the Java platform, it naturally corresponds to eclipse + spring + hibernate. The previous article introduced how to use hibernate in eclipse. This article briefly introduces how to use spring in eclipse. (1) first, download spring from SourceForge, http://sourceforge.net
