我正在使用注释动态创建一个 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

 <!-- 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

从 spring 3.0 开始，您不再需要org.springframework.config.java.process.ConfigurationPostProcessor，只需将 Java-config 类定义为 XML-config 中的 bean。

<bean class="demoproject.ProductFactory" />

尝试删除

<bean class="org.springframework.config.java.process.ConfigurationPostProcessor"/>

您spring-core的运行时类路径中没有。您需要使用适合您项目布局的技术来添加它，例如像 Simon 建议的那样将其添加到 Maven POM。
