No setter found for property 'userDAO' in class 'com.ssh.service.impl.User1Service'

造成此问题的原因是： 在applicationContext.xml中引用

<bean id="userService" class="com.ssh.service.impl.User1Service">

<property name="user1DAO">

<ref bean="User1DAO" />

</property>

</bean>

但是在User1Service中没有定义 成员变量的属性

private User1DAO user1DAO;

public User1DAO getUser1DAO() {

return user1DAO;

}

public void setUser1DAO(User1DAO user1dao) {

user1DAO = user1dao;

}

这样就可以了
