第二章、Srping入门

一、Maven配置

4.0.0
com.huangyian
firstmaven
1.0-SNAPSHOT
jar
    
        
            org.springframework
            spring-context
            4.3.5.RELEASE
            
    

二、一个简单的 Spring bean

1、Bean类

package tg.export;
public class GoodsExport {

    private Integer id;
    
    /**
   * 实现方法
   * @return
   */
    public Integer addGoods() {
        return this.id;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }
}

2、Spring bean 配置文件

3、执行代码

public class App {
    public static void main(String[] args) {
         ApplicationContext context = new ClassPathXmlApplicationContext(
            "config/applicationContext.xml");
         GoodsExport obj = (GoodsExport) context.getBean("GoodsExport");
         System.out.println(obj.addGoods());
    }
}
