Spring框架学习(三)

1.新建AnnotationConfig.java文件取代配置文件

package net.ty.spring.lesson03;

import org.springframework.beans.factory.annotation.Configurable;
import org.springframework.context.annotation.ComponentScan;

@Configurable
@ComponentScan("net.ty.spring.lesson03")
public class AnnotationConfig {
    
}

测试

package net.ty.spring.lesson03;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class TestKnight {

    private AnnotationConfigApplicationContext context; // 基于注解配置类的应用容器

    @Before
    public void init() {
        // 基于注解配置类创建应用容器
        context = new AnnotationConfigApplicationContext(AnnotationConfig.class);
    }

    @Test
    public void testBraveKnight() {
        // 根据名称从应用容器里获取勇敢骑士对象
        BraveKnight knight = (BraveKnight) context.getBean("Mike");
        // 勇敢骑士执行任务
        knight.embarkOnQuest();
    }

    @Test
    public void testDamselRescuingKnight() {
        // 根据名称从应用容器里获取救美骑士对象
        DamselRescuingKnight knight = (DamselRescuingKnight) context.getBean("damselRescuingKnight");
        // 救美骑士执行任务
        knight.embarkOnQuest();
    }

    @After
    public void destroy() {
        // 关闭应用容器
        context.close();
    }
}
