我的ｘｍｌ配置如下：

<property name="driverClassName"
value="com.mysql.jdbc.Driver">

<property name="url" value="jdbc:mysql://127.0.0.1:3306/fan"></property>
<property name="username" value="root"></property>
<property name="password" value="19861005"></property>
</bean>
<bean id="usersdao" class="com.loginsystem.dao.jdbc.usersdaoimpl">
<property name="dataSource">
<ref bean="dataSource" />
</property>
</bean>
<bean id="usersmanager"

singleton="true" lazy-init="default" autowire="default"
dependency-check="default">
<property name="usersdao">
<ref bean="usersdao" />
</property>
</bean>
我在class usersmanagerimpl里面写的ｓｅｔ方法
private usersdao dao;
public void setDao(usersdao usersdao) {
this.dao = usersdao;
}
哪位能帮我看看是什么问题呢？
