spring mvc3.0权限控制

新项目中用到了Spring mvc3.0，之后又升级到3.0.4，因为对静态资源处理有更好支持

<mvc:resources location="/css/" mapping="/css/**" />

spring mvc 3.0最大的特别即是对restful url很友好的支持。但也带来很多不便的地方，比如权限控制。
部分人提出思路例如：
https://jira.springframework.org/browse/SPR-5763
https://jira.springframework.org/browse/SPR-7451

花不少时间阅读源码，发现根本无法扩展对方法级别的控制，也就是使Controller层失去了面向对象的特征，惨！不知道作者是怎么想的，Juergen Hoeller！恨死你了，居然不留一点扩展的余地，要自己写过滤和匹配映射规则虽然能行，但没必要去repeat ，最后无耐Copy源码，修改一翻，想怎么控制就怎么控制了。

总结：
     在一个项目组中，如果要使用新技术，必须要有一个人精通，碰到任何问题都能解决，否则，千万不能用新技术。

spring 配置文件如下：

<bean class="com.jquickwork.extend.AnnotationMethodHandlerAdapter">
		<property name="permissionService">
			<bean class="com.******.manage.web.common.service.PermissionServiceImpl">
				<property name="rightService" ref="RightService"></property>
				<property name="test" value="false" />
			</bean>
		</property>
	</bean>

修改源码后的 AnnotationMethodHandlerAdapter类如下：

看不出什么，只看到老王在卖瓜，呵呵

3 楼 oakeye 2010-10-12  

贴了一大段代码  没看出有什么来

我也是在想这事情，如果都rest了  怎么去控制权限的问题
springsecurity能不能基于方法控制权限

2 楼 7454103 2010-10-12  

修改源码后的 AnnotationMethodHandlerAdapter类如下：
  ？？

1 楼 zhangzi 2010-10-12  

貌似在夸自己很精通？ O(∩_∩)O~!
希望能贡献自己的详细步骤，期待中...
