Spring注解

spring,maven相关

bean

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
    <bean id="helloBean" class="com.yiibai.hello.impl.HelloWorldImpl">
</beans>

等效于以下JavaConfig的配置：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.yiibai.hello.HelloWorld;
import com.yiibai.hello.impl.HelloWorldImpl;
/* http://www.manongjc.com/article/1603.html */
@Configuration
public class AppConfig {
    @Bean(name="helloBean")
    public HelloWorld helloWorld() {
        return new HelloWorldImpl();
    }
}

context这样写

 ApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);
