我正在使用注解动态创建 Bean,但出现以下错误。

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;
}
}

网络.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"/>

错误日志

我怎么知道是什么导致了错误,我可以尝试解决这个问题吗?
