我正在使用注释来动态创建Bean,我收到以下错误.

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;
    }
}

web.xml中

 <!-- 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

我对Jquery比较熟悉,但我正在使用Google Closure.我想知道在Google Closure中是否有任何函数或库,比如jQuery中的.is(),所以我可以检查目标元素是否与css选择器匹配.我找到了一个插件goog.dom.query,但这不是我需要的,因为它用于查找元素.
