简单空指针问题问题，求指点啊

Question

测试用例可以运行！

import com.borosoft.testzzj.exercise.service.CardService;

CardService cs=(CardService)BeanRepository.getBean("cardServer");
System.out.println(cs.haveCard("4028b88154a81fbe0154a8261c240000"));

Controller类中,debug后cardService为null，另一个为userService可行

import com.borosoft.testzzj.exercise.service.CardService;
private CardService cardService;
System.out.println(this.cardService.findById(id).get(0).getCARD_CODE());

配置文件

 <bean id="userBeanDAO" class="com.borosoft.framework.dao.HibernateDAOImpl" p:entityClass="com.borosoft.testzzj.exercise.service.impl.UserServiceImpl" />
    <bean id="userService" class="com.borosoft.testzzj.exercise.service.impl.UserServiceImpl"/>

    <bean id="cardBeanDAO" class="com.borosoft.framework.dao.HibernateDAOImpl" p:entityClass="com.borosoft.testzzj.exercise.service.impl.CardServiceImpl" />
    <bean id="cardServer" class="com.borosoft.testzzj.exercise.service.impl.CardServiceImpl"/>

问题已经找到！！！！

配置文件下cardServer，改成cardService

    <bean id="cardServer" class="com.borosoft.testzzj.exercise.service.impl.CardServiceImpl"/>
