Caused by: java.lang.ClassNotFoundException: entity.Red
这个实体有吗？

Answer 2

有<bean name="Red" class="entity.Red">
</bean>
这样写对吗？

这个是spring的配置 
你这个文件在spring.xml里引用了没?

报的错是：
 Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name '/user' defined in ServletContext resource [/WEB-INF/classes/spring.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/objectweb/asm/Type

Answer 6

entity.Red这个实体的hbm文件没在Hibernate.xml中映射吧

Answer 7

struts的配置文件中配置的action是否和spring中的一致！！！
