j2EE編寫時易錯問題。

Does the parameter type of the setter match the return type of the getter?

意思就是在com.jixiang.service.impl.UserServiceImpl這個類中沒有找到recordDao,或者沒有recordDao的setter方法。

但是你在Spring的applicationContext.xml配置中又加入了這個配置

<bean id="managerTemplate" abstract="true" lazy-init="true"
      p:mangerDao-ref="managerDao"
      p:userDao-ref="userDao"
      p:recordDao-ref="recordDao"
      />
<bean id="user_service"
      class="com.jixiang.service.impl.UserServiceImpl"
      parent="managerTemplate"/><!--class的類名一定要對-->

。
