关于spring配置的问题，请教一下

<!-- 定义多视图控制器 -->
<bean id="userMethodResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
<property name="paramName"><value>action</value></property>
</bean>
<bean id="usersAction" class="com.page.action.UsersAction">
<property name="methodNameResolver"><ref bean="userMethodResolver"/></property>
</bean>
<bean id="regusersAction" class="com.page.action.RegUsersAction">
<property name="methodNameResolver"><ref bean="userMethodResolver"/></property>
</bean>
我有二个class；UsersAction和RegUsersAction，里面有多个方法，我现在想用多视图控制器来实现控制。

如果是实现一个class下边这样写没有问题
<bean id="userMethodResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
<property name="paramName"><value>action</value></property>
</bean>
<bean id="usersAction" class="com.page.action.UsersAction">
<property name="methodNameResolver"><ref bean="userMethodResolver"/></property>
</bean>

当我加入第二个class时就出问题了
<bean id="regusersAction" class="com.page.action.RegUsersAction">
<property name="methodNameResolver"><ref bean="userMethodResolver"/></property>
</bean>
请问这样的问题怎么解决呢？

<bean id="regusersAction" class="com.page.action.RegUsersAction"> <property name="methodNameResolver"><ref bean="userMethodResolver"/></property> </bean> id 重复了，在一个Spring的Container里，ID是唯一的，不能重复。

<bean id="regusersAction" class="com.page.action.RegUsersAction"> <property name="methodNameResolver"><ref bean="userMethodResolver"/></property> </bean> id 重复了，在一个Spring的Container里，ID是唯一的，不能重复。

请问大大，怎么改呢？

你把第二个property 的name改成与上面不一样

我改了之后要报错org.springframework.beans.NotWritablePropertyException: Invalid property 'methodNameResolver123' of bean class [com.page.action.RegUsersAction]: Bean property 'methodNameResolver123' is not writable or has an invalid setter method.

<bean id="userMethodResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver"> <property name="paramName"><value>action</value></property> </bean> <bean id="userMethodResolver1" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver"> <property name="paramName"><value>action</value></property> </bean> <bean id="usersAction" class="com.page.action.UsersAction"> <property name="methodNameResolver"><ref bean="userMethodResolver"/></property> </bean> <bean id="regusersAction" class="com.page.action.RegUsersAction"> <property name="methodNameResolver"><ref bean="userMethodResolver1"/></property> </bean> 这样改是没有问题的，不过养配置也太怪了吧，我要加入一个class就要创建一个多视图控制器吗？

[lucky_love123]

而且你可以把class写在同一个控制器里面吧

[jsp_rookie]

问题就是卡在不知道多个class怎么写在同一个控制器里面？
