我利用了 <controller> 标记来用 DelegatingRequestProcessor 覆盖默认的 Struts RequestProcessor。下一步是在我的 Spring 配置文件中注册该动作，如清单 3 所示：
清单 3. 在 Spring 配置文件中注册一个动作
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="bookService" class="ca.nexcel.books.business.BookServiceImpl"/>
<bean name="/searchSubmit"
class="ca.nexcel.books.actions.SearchSubmit"> |(1)
<property name="bookService">
<ref bean="bookService"/>
</property>
</bean>
</beans>
使用Spring更好地处理Struts动作(4)

注意：在 (1) 处，我使用名称属性注册了一个 bean，以匹配 struts-config 动作映射名称。SearchSubmit 动作揭示了一个 JavaBean 属性，允许 Spring 在运行时填充属性，如清单 4 所示：
