Question

我正在使用Struts 2和Springs 4.0.0.M1，应用程序正在部署。没有提到应用程序的范围，因此它被实例化为“Singleton”。所有的bean都是预先实例化和定义的但是我没有收到消息： - “创建单例bean的共享实例”。

所以我猜这些bean没有被使用，使得应用程序在生产中变慢。我正在使用接口，我的类在bean中定义，如某些论坛中所建议的那样。

请指导。

我的application-context.xml就像

<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:context="http://www.springframework.org/schema/context"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd">

 <context:component-scan base-package="com.javahash.spring.controller" />

<bean id="login" class ="syntel.arch.action.SKBLoginAction">
        <property name="skbLoginService">
            <ref bean="skbLoginService"/>
        </property> 
    </bean>

    <bean id="skbLoginService" class="syntel.arch.service.impl.SKBLoginServiceImpl">
        <property name="skbLoginDAO">
            <ref bean="skbLoginDAO"/>
        </property>
    </bean>

</beans>

和web.xml

<?xml version="1.0"?>
    <web-app xmlns="http://java.sun.com/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
