Spring Security提供了单点登出的功能,可以通过以下步骤实现:
1. 配置LogoutFilter
在Spring Security配置文件中添加LogoutFilter,并设置logoutUrl参数为/logout,例如:
```
<security:logout logout-url="/logout" />
```
2. 配置SingleSignOutFilter
在Spring Security配置文件中添加SingleSignOutFilter,例如:
```
<bean id="singleSignOutFilter" class="org.jasig.cas.client.session.SingleSignOutFilter">
<property name="casServerUrlPrefix" value="https://cas.example.com" />
</bean>
```
3. 配置SessionRegistry
在Spring Security配置文件中配置SessionRegistry,例如:
```
<bean id="sessionRegistry" class="org.springframework.security.core.session.SessionRegistryImpl" />
```
4. 配置ConcurrentSessionFilter
在Spring Security配置文件中添加ConcurrentSessionFilter,并设置sessionRegistry属性为上一步中配置的SessionRegistry,例如:
```
<security:concurrent-session-control session-registry-alias="sessionRegistry" />
```
5. 配置LogoutHandler
在Spring Security配置文件中配置LogoutHandler,例如:
```
<bean id="logoutHandler" class="org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler">
<property name="invalidateHttpSession" value="true" />
<property name="clearAuthentication" value="true" />
</bean>
```
6. 配置LogoutSuccessHandler
在Spring Security配置文件中配置LogoutSuccessHandler,例如:
```
<bean id="logoutSuccessHandler" class="org.springframework.security.web.authentication.logout.SimpleUrlLogoutSuccessHandler">
<property name="defaultTargetUrl" value="/" />
</bean>
```
7. 配置FilterChainProxy
在Spring Security配置文件中配置FilterChainProxy,例如:
```
<bean id="springSecurityFilterChain" class="org.springframework.security.web.FilterChainProxy">
<sec:filter-chain-map path-type="ant">
<sec:filter-chain pattern="/logout" filters="singleSignOutFilter,logoutFilter" />
<sec:filter-chain pattern="/**" filters="concurrencyFilter,securityFilterChain" />
</sec:filter-chain-map>
</bean>
```
以上步骤配置完成后,用户在访问/logout时会触发单点登出操作,即使用户在其他应用中也会被同时登出。
