Integrating Apache Shiro into Spring-based Applications

Shiro 的组件都是JavaBean/POJO 式的组件，所以非常容易使用Spring进行组件管理，可以非常方便的从ini配置迁移到Spring进行管理，且支持JavaSE应用及Web 应用的集成。

Web Applications

1、web.xml

<!-- 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>

2、applicationContext.xml

In your applicationContext.xml file, define the web-enabled SecurityManager and the ‘shiroFilter‘ bean that will be referenced from web.xml.

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


<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>

Enabling Shiro Annotations

In both standalone and web applications, you might want to use Shiro‘s Annotations for security checks (for example, @RequiresRoles,@RequiresPermissions, etc. This requires Shiro‘s Spring AOP integration to scan for the appropriate annotated classes and perform security logic as necessary.

Here is how to enable these annotations. Just add these two bean definitions to applicationContext.xml:

<!-- 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>
