弹簧安全性自定义注销处理程序

以下解决方案对我有用，可能会有所帮助：

1. 扩展 SimpleUrlLogoutSuccessHandler 或实现 LogoutHandler：

   public class LogoutSuccessHandler extends SimpleUrlLogoutSuccessHandler {
   
      // Just for setting the default target URL
      public LogoutSuccessHandler(String defaultTargetURL) {
           this.setDefaultTargetUrl(defaultTargetURL);
      }
   
      @Override
      public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
   
           // do whatever you want
           super.onLogoutSuccess(request, response, authentication);
      }
   }
   

2. 添加到您的弹簧安全配置：

   <security:logout logout-url="/logout" success-handler-ref="logoutSuccessHandler" />
   <bean id="logoutSuccessHandler" class="your.package.name.LogoutSuccessHandler" >
       <constructor-arg value="/putInYourDefaultTargetURLhere" />
   </bean>
   

在Spring Security Forum上看到这篇文章的答案：

XML 定义：

<beans:bean id="logoutFilter" class="org.springframework.security.ui.logout.LogoutFilter">
    <custom-filter position="LOGOUT_FILTER"/>
    <beans:constructor-arg index="0" value="/logout.jsp"/>
    <beans:constructor-arg index="1">
        <beans:list>
            <beans:ref bean="securityContextLogoutHandler"/>
            <beans:ref bean="myLogoutHandler"/>
        </beans:list>
    </beans:constructor-arg>
</beans:bean>

<beans:bean id="securityContextLogoutHandler" class="org.springframework.security.ui.logout.SecurityContextLogoutHandler"/>

<beans:bean id="myLogoutHandler" class="com.whatever.CustomLogoutHandler">
    <beans:property name="userCache" ref="userCache"/>
</beans:bean>

注销处理程序类：

public class CustomLogoutHandler implements LogoutHandler {
    private UserCache userCache;

    public void logout(final HttpServletRequest request, final HttpServletResponse response, final Authentication authentication) {
        // ....
    }

    @Required
    public void setUserCache(final UserCache userCache) {
        this.userCache = userCache;
    }
}
