Spring Learning (+)---generic-based automatic assembly of Java class-based configuration beans (Spring4 new)

Example:

Defining a generic Store

Package Javabased;public interface Store<t> {}

Two implementation Classes Stringstore,integerstore

Package Javabased;public class Integerstore implements store<integer> {}

Package Javabased;public class Stringstore implements store<string> {}

Java Config implements bean configuration

Package Javabased;import Org.springframework.beans.factory.annotation.autowired;import Org.springframework.context.annotation.bean;import org.springframework.context.annotation.configuration;@ Configurationpublic class Storeconfig {@Autowiredprivate store<string> s1; @Autowiredprivate Store<integer > s2, @Beanpublic stringstore Stringstore () {return new Stringstore (); @Beanpublic Integerstore Integerstore () {return new Integerstore ();} @Bean (name= "test_generic") public String print () {    //test System.out.println ("S1:" +s1.getclass (). GetName ()); System.out.println ("S2:" +s2.getclass (). GetName ()); return "";}}

XML configuration:

<?xml version= "1.0" encoding= "UTF-8"?> <beans xmlns= "Http://www.springframework.org/schema/beans"        Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"        xmlns:context= "Http://www.springframework.org/schema /context "        xsi:schemalocation=" Http://www.springframework.org/schema/beans/            http Www.springframework.org/schema/beans/spring-beans-4.1.xsd            Http://www.springframework.org/schema/context            http://www.springframework.org/schema/context/spring-context-4.1.xsd ">                <context:component-scan Base-package= "javabased" >        </context:component-scan>         </beans>

Unit tests:

Package Javabased;import Org.junit.test;import Org.springframework.context.applicationcontext;import Org.springframework.context.support.classpathxmlapplicationcontext;public class UnitTest {@Testpublic void Test () { ApplicationContext context = new Classpathxmlapplicationcontext ("Classpath:spring-beanannotation.xml");  Context.getbean ("Test_generic");}}
