注釈を使用して Bean を動的に作成していますが、次のエラーが発生します。

package demoproject;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class ProductFactory {

    public ProductFactory() {
        // TODO Auto-generated constructor stub
    }

    @Bean   
    public Product josh(){
        Product josh = new Battery();
        josh.setId("cdrw");
        josh.setPrice(100);
        return josh;
    }
}

web.xml

 <!-- Bean for JavaConfig -->
   <bean  class='demoproject.ProductFactory' />
   <!-- be sure to include the JavaConfig bean post-processor -->
   <bean class="org.springframework.config.java.process.ConfigurationPostProcessor"/>

spring-core実行時のクラスパスがありません。Simon が提案するように Maven POM に追加するなど、プロジェクト レイアウトに適した手法を使用して追加する必要があります。
