, because it does not involve compilation, where one bean only needs to declare ' ref= ' Somebean "', leaving the rest to spring to be processed during container initialization. Of course, when using the @configuration class, the Java compiler has some limitations on configuration patterns, and references to other beans must be legitimate Java syntax.Fortunately,

New lightweight Java Open source Framework---SpringEggWeibo : Http://weibo.com/xtfggefSource:http://blog.csdn.net/zhangerqingSpring is a lightweight Java framework whose core idea is Di (Dependency injection, which is dependency injection) and IOC (inversion of control, that is, controlled inversion) because of its open source, low intrusion, It has now swept through a large segment of the market, its bigge

They are mainly used to optimize the processing operations on time and date before Java 8. However, when we use

Quote a passage from the SPRING2.0 Technical manual: The core of spring is a lightweight container that implements the IOC container and non-intrusive framework, provides a way to implement the AOP concept, provides support for persistence layers, transactions, provides implementations of the MVC Web Framework, and provides a consistent model encapsulation for some common enterprise service APIs, is a comprehensive application framework, and in addit

After JDK1.5, Java.lang.instrument.Instrumentation is provided, that is, the Java Agent mechanism can implement redefinition and retransform of classes.redefinition corresponds to instrumentation.redefineclasses () to enable hot substitution of classes, but unfortunately the function is limited. 1 2 3 4 The redefinition change method bodies, the constant pool and attributes. The redefinition must not add, remove or rename fields o

The IOC (inverse of control) can be translated as "controlled inversion", but most people are accustomed to calling it "dependency injection". In spring, the implementation class, parameter information, etc. can be configured in the corresponding configuration file by IOC, so when the implementation class or parameter information needs to be changed, only the configuration file needs to be modified, and this method further reduces the coupling between

j2ee| Beginners First, the basic knowledge of Java Foundation, object-oriented Foundation and design pattern is essential. If even these basic knowledge is not solid enough, I suggest that the first to make up a lesson. About design Patterns I don't think I need to learn much, but the following three models are essential to learning Spring: Factory mode (including simple factory and abstract factory), stra

Spring 3 for beginners of Java ssh, sshspring In this article, I learned two ways of dependency injection: Set Value injection and construct injection. In our previous thinking, if we call a class, we need to manually instantiate it. When we create a called job that does not need to be completed, this is the control reversal, when the called instance process is completed by

Laravel makes many features easy, from security to scale and speed. This makes the Java framework awkward, such as spring MVC, which covers a lot of features, but is less developed than Laravel. What are the advantages of this kind of PHP framework compared to laravel like spring MVC? Reply content:First, SPRINGLEMVC is just a small module inside the

transaction management: @Transactional (propagation=propagation.not_supported) Note: If the exception is try{}catch{}, the transaction is not rolled back, and if you want the transaction to roll back, you must throw the Try{}catch{throw Exception} out.A unified exception hierarchy is required to provide a service abstraction. The most important thing is org.springframework.dao.DataAccessException and its subclasses. It is important to emphasize that spring's anomaly mechanism focuses on th
