Spring Security 是一个非常流行的安全框架,可以用来实现很多不同的安全需求,包括单点登录。下面是一个基于 Spring Security 的单点登录流程的简单示例:
1. 配置 Spring Security
在 Spring 配置文件中配置 Spring Security,包括定义用户、角色、权限等信息。例如:
```xml
<security:authentication-manager>
<security:authentication-provider>
<security:user-service>
<security:user name="user1" password="password1" authorities="ROLE_USER" />
<security:user name="user2" password="password2" authorities="ROLE_USER" />
</security:user-service>
</security:authentication-provider>
</security:authentication-manager>
<security:http auto-config="true" use-expressions="true">
<security:intercept-url pattern="/welcome*" access="hasRole('ROLE_USER')" />
<security:form-login login-page="/login.jsp" default-target-url="/welcome" authentication-failure-url="/login.jsp?error=true" />
<security:logout logout-success-url="/login.jsp" />
<security:csrf disabled="true" />
</security:http>
```
2. 配置单点登录服务器
在单点登录服务器上配置 Spring Security,实现单点登录逻辑。例如:
```xml
<security:http pattern="/sso/**" create-session="stateless"
entry-point-ref="ssoEntryPoint" authentication-manager-ref="ssoAuthenticationManager">
<security:intercept-url pattern="/sso/login" access="permitAll"/>
<security:intercept-url pattern="/sso/logout" access="permitAll"/>
<security:intercept-url pattern="/sso/**" access="isAuthenticated()"/>
<security:custom-filter ref="ssoFilter" before="FILTER_SECURITY_INTERCEPTOR"/>
</security:http>
<bean id="ssoFilter" class="org.springframework.security.sso.SsoFilter">
<property name="authenticationManager" ref="ssoAuthenticationManager"/>
<property name="authenticationSuccessHandler" ref="ssoAuthenticationSuccessHandler"/>
<property name="authenticationFailureHandler" ref="ssoAuthenticationFailureHandler"/>
<property name="logoutSuccessHandler" ref="ssoLogoutSuccessHandler"/>
</bean>
<bean id="ssoAuthenticationManager" class="org.springframework.security.sso.SsoAuthenticationManager">
<property name="ssoService" ref="ssoService"/>
</bean>
<bean id="ssoEntryPoint" class="org.springframework.security.sso.SsoAuthenticationEntryPoint">
<property name="ssoService" ref="ssoService"/>
</bean>
<bean id="ssoAuthenticationSuccessHandler" class="org.springframework.security.sso.SsoAuthenticationSuccessHandler">
<property name="ssoService" ref="ssoService"/>
<property name="defaultTargetUrl" value="http://localhost:8080/welcome"/>
</bean>
<bean id="ssoAuthenticationFailureHandler" class="org.springframework.security.sso.SsoAuthenticationFailureHandler">
<property name="ssoService" ref="ssoService"/>
<property name="defaultFailureUrl" value="http://localhost:8080/login.jsp?error=true"/>
</bean>
<bean id="ssoLogoutSuccessHandler" class="org.springframework.security.sso.SsoLogoutSuccessHandler">
<property name="ssoService" ref="ssoService"/>
<property name="defaultTargetUrl" value="http://localhost:8080/login.jsp"/>
</bean>
<bean id="ssoService" class="org.springframework.security.sso.InMemorySsoService">
<property name="ssoUrls">
<map>
<entry key="http://localhost:8080/**" value="http://localhost:8081/sso/login"/>
</map>
</property>
</bean>
```
3. 配置客户端
在客户端应用程序上配置 Spring Security,以便它可以与单点登录服务器交互,并从服务器获取用户认证信息。例如:
```xml
<security:http auto-config="true">
<security:intercept-url pattern="/welcome*" access="hasRole('ROLE_USER')" />
<security:custom-filter ref="ssoFilter" position="FIRST" />
</security:http>
<bean id="ssoFilter" class="org.springframework.security.sso.SsoClientFilter">
<property name="ssoService" ref="ssoService" />
<property name="authenticationSuccessHandler" ref="ssoClientAuthenticationSuccessHandler" />
<property name="authenticationFailureHandler" ref="ssoClientAuthenticationFailureHandler" />
</bean>
<bean id="ssoService" class="org.springframework.security.sso.InMemorySsoService">
<property name="ssoUrls">
<map>
<entry key="http://localhost:8081/**" value="http://localhost:8080/sso/login" />
</map>
</property>
</bean>
<bean id="ssoClientAuthenticationSuccessHandler" class="org.springframework.security.sso.SsoClientAuthenticationSuccessHandler">
<property name="defaultTargetUrl" value="/welcome" />
</bean>
<bean id="ssoClientAuthenticationFailureHandler" class="org.springframework.security.sso.SsoClientAuthenticationFailureHandler">
<property name="defaultFailureUrl" value="/login.jsp?error=true" />
</bean>
```
这些示例代码只是一个简单的示例,实际实现中可能需要更多的配置和定制。但是,它们提供了一个基本的框架,可以用于实现一个基于 Spring Security 的单点登录系统。
