Spring Configures beans with annotationsConfiguring beans based on annotationsTo configure the Bean's properties based on annotationsScanning components in the ClasspathComponent scanning (component scanning): Spring is able to automatically scan, detect and instantiate components with specific annotations from the classpath.Specific components include the following:[Email protected]: basic annotations that

In spring, objects are not responsible for finding and creating other objects that they require. Creating an associated action between two application objects is a core feature of dependency injection, often referred to as assembly.It is spring's responsibility to create beans and build relationships between them, but it is the responsibility of the developer to tell spring which beans need to be created an

Lin Bingwen Evankaka Original works. Reprint please specify the source Http://blog.csdn.net/evankakaIn this paper, we mainly talk about the relationship between beans in spring, which are divided into three types: inheritance, dependency and reference. Examples and usage analysis are given in the article. first, inherit bean configuration Spring allows inheritance of the bean's configuration , the inherited Bean is called the parent bean, a

Xml Piecing together beans within the spring container is called assembly. When you assemble a bean, you are telling the container what beans are needed and how the container uses dependency injection to tie them together.In theory, the bean assembly can be obtained from any resource, including property files, relational databases, and so on, but XML is the most common spring application system configuratio

Three ways to instantiate a bean entityThere are three ways to instantiate a bean in spring:First, instantiate with a constructor; (usually a method used, focus)Second, the use of static factory method instantiation;Third, the use of example chemical plant method instantiationThe first, using the constructor instantiation;This instantiation may be the most used in our usual development, because it is simple to configure in an XML file and does not require additional factory classes to implement.

Reprinted from http://blog.csdn.net/legendj/article/details/9950963Today, when writing the spring AOP example, a red fork appears after adding the spring AOP schema in the Spring.xml file, and the spring configuration file is as follows: XML version= "1.0" encoding= "UTF-8"?> Beansxmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"Xmlns:context= "Http://www.springframework.org/schema/conte

Most of the work of the spring framework is the management of beans, including the management of the bean's life cycle and the use of the bean inheritance function.Abstract bean and child beanTo prevent too many very similar beans from appearing in XML, we use abstract beans to extract common information and mark it with the abstract attribute as true. It cannot

The Spring framework Bean supports the following five scopes:Here are two scopes, Singleton and ProtoypeSingleton scopeThe singleton scope is the default scope, and Getbean is the same bean within the same IOC container, and if you create an object instance that is defined by a singleton scope Bean, the instance is stored in the bean's cache, then all future targets for that Both the Bean's request and the reference return the cached object.Writing Helloworld.java1 Packagecom.example.spring;2 3
