spring与shiro的集成

web.xml中的配置:

<!-- The filter-name matches name of a 'shiroFilter' bean inside applicationContext.xml -->

<filter>
    <filter-name>shiroFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    <init-param>
        <param-name>targetFilterLifecycle</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>


<!-- Make sure any request you want accessible to Shiro is filtered. /* catches all -->
<!-- requests.  Usually this filter mapping is defined first (before all others) to -->
<!-- ensure that Shiro works in subsequent filters in the filter chain:             -->
<filter-mapping>
    <filter-name>shiroFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

applicationContext.xml

你在applicationContext.xml文件，定义SecurityManager和“shirofilter的bean被引用web.xml。

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
    <property name="securityManager" ref="securityManager"/>
    <!-- override these for application-specific URLs if you like:
    <property name="loginUrl" value="/login.jsp"/>
    <property name="successUrl" value="/home.jsp"/>
    <property name="unauthorizedUrl" value="/unauthorized.jsp"/> -->
    <!-- The 'filters' property is not necessary since any declared javax.servlet.Filter bean  -->
    <!-- defined will be automatically acquired and available via its beanName in chain        -->
    <!-- definitions, but you can perform instance overrides or name aliases here if you like: -->
    <!-- <property name="filters">
        <util:map>
            <entry key="anAlias" value-ref="someFilter"/>
        </util:map>
    </property> -->
    <property name="filterChainDefinitions">
        <value>
            # some example chain definitions:
            /admin/** = authc, roles[admin]
            /docs/** = authc, perms[document:read]
            /** = authc
            # more URL-to-FilterChain definitions here
        </value>
    </property>
</bean>

<!-- Define any javax.servlet.Filter beans you want anywhere in this application context.   -->
<!-- They will automatically be acquired by the 'shiroFilter' bean above and made available -->
<!-- to the 'filterChainDefinitions' property.  Or you can manually/explicitly add them     -->
<!-- to the shiroFilter's 'filters' Map if desired. See its JavaDoc for more details.       -->
<bean id="someFilter" class="..."/>
<bean id="anotherFilter" class="..."> ... </bean>
...

<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
    <!-- Single realm app.  If you have multiple realms, use the 'realms' property instead. -->
    <property name="realm" ref="myRealm"/>
    <!-- By default the servlet container sessions will be used.  Uncomment this line
         to use shiro's native sessions (see the JavaDoc for more): -->
    <!-- <property name="sessionMode" value="native"/> -->
</bean>
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>

<!-- Define the Shiro Realm implementation you want to use to connect to your back-end -->
<!-- security datasource: -->
<bean id="myRealm" class="...">
...
</bean>

使用shiro的注解配置

在web运用中,你可能想用shiro的注解作安全检查(例如:@RequiresRoles, @RequiresPermissions,等等),这要求shiro的spring aop
整合能扫描那些带注解的类b并执行安全逻辑。下面是如何启用这些注解,仅仅增加下面两个bean的配置.

<!-- Enable Shiro Annotations for Spring-configured beans.  Only run after -->
<!-- the lifecycleBeanProcessor has run: -->
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/>
<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
    <property name="securityManager" ref="securityManager"/>
</bean>

shiro还支持远程调用的安全,详细配置请参考shiro官网:http://shiro.apache.org/spring.html#Spring-WebApplications

Shiro登录 filterChainDefinitions中过滤器说明:

Filter Name     Class
anon            org.apache.shiro.web.filter.authc.AnonymousFilter
authc           org.apache.shiro.web.filter.authc.FormAuthenticationFilter
authcBasic      org.apache.shiro.web.filter.authc.BasicHttpAuthenticationFilter
perms           org.apache.shiro.web.filter.authz.PermissionsAuthorizationFilter
port            org.apache.shiro.web.filter.authz.PortFilter
rest            org.apache.shiro.web.filter.authz.HttpMethodPermissionFilter
roles           org.apache.shiro.web.filter.authz.RolesAuthorizationFilter
ssl             org.apache.shiro.web.filter.authz.SslFilter
user            org.apache.shiro.web.filter.authc.UserFilter

logout         org.apache.shiro.web.filter.authc.LogoutFilter
注：anon，authcBasic，auchc，user是认证过滤器，
perms，roles，ssl，rest，port是授权过滤器

anon:例子/admins/**=anon 没有参数，表示可以匿名使用。
authc:例如/admins/user/**=authc表示需要认证(登录)才能使用，没有参数
roles：例子/admins/user/**=roles[admin],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，当有多个参数时，例如admins/user/**=roles["admin,guest"],每个参数通过才算通过，相当于hasAllRoles()方法。
perms：例子/admins/user/**=perms[user:add:*],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，例如/admins/user/**=perms["user:add:*,user:modify:*"]，当有多个参数时必须每个参数都通过才通过，想当于isPermitedAll()方法。
rest：例子/admins/user/**=rest[user],根据请求的方法，相当于/admins/user/**=perms[user:method] ,其中method为post，get，delete等。
port：例子/admins/user/**=port[8081],当请求的url的端口不是8081是跳转到schemal://serverName:8081?queryString,其中schmal是协议http或https等，serverName是你访问的host,8081是url配置里port的端口，queryString
是你访问的url里的？后面的参数。
authcBasic：例如/admins/user/**=authcBasic没有参数表示httpBasic认证
ssl:例子/admins/user/**=ssl没有参数，表示安全的url请求，协议为https
user:例如/admins/user/**=user没有参数表示必须存在用户，当登入操作时不做检查
