在Spring Security中,实现访问控制或权限控制是很是容易实现的,请看下面的代码片断:html

<
http
auto-config
=
"true"
>
<
intercept-url
pattern
=
"/admin*"
access
=
"ROLE_ADMIN"
/>
</
http
>
|
它的意思是,只有“ROLE_ADMIN”权限的用户能够容许访问“ /admin*”路径,若是没有权限的用户访问则会提示“http 403 access denied page”错误。java
本次教程中,咱们像你展现只有“ROLE_ADMIN”权限的用户能够访问“/admin*”web
访问控制须要Spring Security的核心包,请参考Spring+Spring Security+Maven 实现的一个Hello World例子 列出的jarspring
Spring MVC作控制器并返回一个“hello”视图,这个你应该能够理解的。app
WelcomeController.javaeclipse

http://localhost:8080/SpringMVC/adminui
1.默认的登录页面以下所示:url
2.若是用“it161”登录时,就会提示“http 403 is access denied page”,由于it161是“ROLE_USER”权限
3.若是用“eclipse”登录的话,“hello.jsp”就会展现,由于“eclipse”是“ROLE_ADMIN“权限。
默认的403页面很是丑陋,请能够阅读本人自定义你的403页面:Spring Security教程-Spring Security实现访问控制
