[最优解释]
要使用context.getBean()，前提是spring配置加载成功，显然你这因为Error creating bean with name 'productService' 这个错误，spring没有加载成功.
合理的办法是在ProductService类里面，不用context.getBean()获取实例，而是定义成ProductService类的私有成员，然后在spring当中配置注入
<bean id="productService"
class="com.sand.service.ProductService">
<property name="productDao" ref="productdaoSqls"></property>
</bean>
[其他解释]
ProductService 47行init方法 空指针
[其他解释]
既然用spring注入，为什么还要在类中context.getBean()
[其他解释]
不该context.getBean()获得实例吗
哪位大哥给个解决方案啊，我知道初始化错了
但是不知道怎么改啊
