一个关于spring的applicationcontext的问题

Question

我的代码如下
<?xml version="1.0" encoding="UTF-8"?>

</bean>

<bean id="ManagerLoginAction" class="com.air.action.ManagerLoginAction">
<property name="ManagerService" ref ="ManagerService"></property>
</bean>
//关键就是错在 managerservice 和managerloginaction两端 编译器说invalid property name‘ManagerinfoDAO’‘ManagerService’not javabean compliant
</beans>

Answer 1

在com.air.action.ManagerLoginAction里面有ManagerService属性吗？

Answer 2

在com.air.action.ManagerLoginAction里面有ManagerService属性，并且有相应的符合javabean命名规范的get、set方法吗

Answer 3

spring  注入用set或是构造,,,你看看你程序.

Answer 4

你没有在dao配置文件中定义配置 ManagerinfoDAO 的注入的实现类，所以才报错，定义的ManagerService找不到的<property name="ManagerinfoDAO" ref="ManagerinfoDAO"/> 对应的“ref="ManagerinfoDAO"”

Answer 5

ManagerinfoDAO 改为 managerinfoDAO 
再进行get set 看看

Answer 6

应该是属性命名错误，属性改成managerinfoDAO，再设置相应的get，set

Answer 7

ManagerService 在action中你也叫这个名字吗？set方法有吗？
