从Spring 3起，JavaConfig功能已经包含在Spring核心模块，它允许开发者将bean定义和在Spring配置XML文件到Java类中。
interface:
package spring_config; /** * Created by luozhitao on 2017/8/10. */ public interface hello0810 { public void printMsg(String msg); }
imp:
package spring_config; /** * Created by luozhitao on 2017/8/10. */ public class hello0810imp implements hello0810{ public void printMsg(String msg) { System.out.println("0810"+msg); } }
使用 @Configuration 注释告诉 Spring，这是核心的 Spring 配置文件，并通过 @Bean 定义 bean。
package spring_config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; /** * Created by luozhitao on 2017/8/10. */ @Configuration public class APPconfig { @Bean(name = "hellobean") public hello0810 hello(){ return new hello0810imp(); } }
main:
package spring_config; import org.springframework.context.ApplicationContext; import org.springframework.context.annotation.AnnotationConfigApplicationContext; /** * Created by luozhitao on 2017/8/10. */ public class APP_main { public static void main(String [] args){ ApplicationContext context=new AnnotationConfigApplicationContext(APPconfig.class); hello0810 ho=(hello0810)context.getBean("hellobean"); ho.printMsg("spring_config"); } }
-----------------------
使用@Import加载多个配置文件。
package com.yiibai.config; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Import; @Configuration @Import({ CustomerConfig.class, SchedulerConfig.class }) public class AppConfig { }
