Spring Java-based container configuration Over the years, a large number of XML configurations and complex dependency management in Spring have been criticized. To implement XML-free development experience, Spring adds new Configuration annotations to support the Java Config

The IOC (inverse of control) can be translated as "controlling reversal," but most people are accustomed to calling it "dependency injection". In spring, the IOC can configure the implementation class, parameter information, and so on in its corresponding configuration file, so that if you need to change the implementation class or parameter information, you only need to modify the configuration file, which further reduces the coupling between classes

Spring MVC: Java template engine Thymeleaf (2) This article was originally designed to directly introduce Thymeleaf's view parsing, but considering the convenience of learning, we decided to build a spring-mvc first. All the following processes require only one notepad and JDK. Step 1: Use maven to build a web app. mvn archetype:generate -DgroupId=org.nwpu.chen

runtime dynamic proxies. AOP is actually a continuation of the GOF design pattern, the design pattern pursues the decoupling between the caller and the callee, improves the flexibility and scalability of the code, and AOP can be said to be an implementation of this goal. Provides rich support for aspect-oriented programming in spring, allowing for cohesive development through separation of application business logic and system-level services such as

This year I have been thinking about the problem of the separation of the front and back of web development, and now there is a lot of snacks, with this problem in depth, and now the company many Web project control layer of the technical framework moved from STRUTS2 to Springmvc, I suddenly have a new question can not get the correct explanation , why do we do Java Web Development now, would choose a framework such as struts2 or SPRINGMVC, rather tha

The rapidly evolving developer community, support for a variety of backend technologies (including JMS, JTA, JDO, Hibernate, Ibatis, and so on), and (more importantly) non-intrusive lightweight IOC containers and built-in AOP runtimes, these factors make spring The framework is very attractive for Java EE application development. Spring-Hosted components (POJO) c

After the release of Java 8 with many new features and libraries, Spring 4.x already supports most of them. Some of the new features of Java 8 have no effect on spring and can be used directly, but some new features require spring support. This article will take you through

Write a method in this class that deals with the same effect in the core business.We also need to know two keyword:　connection point (Joinpoint), a simple understanding is the method defined in the tangent module.

1. Releasing POJOs EnergyTraditional development is how to bind POJOs, if you have developed Java for a long time, then you must have been exposed to the development of EJB. At the time, developing a small function would extend the framework's class or implement its interface. So it's easy to see the skeleton code that hacked into your app in the early Struts,webwork,taperstry framework.Spring as much as possible to avoid filling in your app with its

QuoteTo learn the spring framework of the technical insider, you must master some basic Java knowledge, is the so-called "ascend will inferiority, involved in the far must from you." The following Java knowledge is closely related to the spring framework, and it's important to learn (I'll introduce these

unconsciously use these two objects in actual development. And I do front-end development very like to use Ajax, when using AJAX technology I hate Struts2 's custom tags, I prefer to use JavaScript technology in the page to deal with a variety of information, the final struts2 in my eyes is a servlet variant, So there was a time when I often wondered if I could abandon struts2 and use servlets directly, because struts2 used too many reflection mechanisms, especially with annotations (annotation

Absrtact: This article is about Java in the use of the spring cache decoupling business, although the previous implementation of caching, is defined by the cache operation interface, can flexibly implement different caching, but after all, the energy is limited, to complete a different cache implementation is also a problem. What's more, code that has a lot of caching in the business code is too coupling to
