return false;
}


}麻烦大家帮我看一下 这个错误是什么原因导致的

Answer 1

你的配置文件中没有UserInfoDao呀，把该文件关闭，然后重新打开问题也许就没了，编译一下看看是否仍然报错。其实显示红叉没什么，只要能运行、不出错就ＯＫ。你试试运行是否报错，如果出错，请把异常信息贴出来

Answer 3

 <bean id="userinfoservice"  class="com.test.service.UserInfoServiceImpl">
        <property name="userinfodaoimpl"> //这样提示红叉Invalid property name 'UserInfoDao' - not JavaBean compliant 
        <ref bean="userinfodaoimpl"/>
        </property>
    </bean>按Ctrl 点击下设置的属性，看看是否能够进入<property name="userinfodaoimpl"> <ref bean="userinfodaoimpl"/>
都点一下，假如是能注入肯定是能点击查找的，就跟java的类、方法一样
