注册singleSignOutFilter，注入RedisBackedSessionMappingStorage

```
@Configuration
@EnableRedisHttpSession
public class RedisSessionConfig {
    @Autowired
    RedisTemplate redisTemplate;
    @Autowired
    SessionRepository sessionRepository;

    /**
     * 注册单点登出filter
     *
     * @return
     */
    @Bean
    public FilterRegistrationBean singleSignOutFilter() {
        FilterRegistrationBean bean = new FilterRegistrationBean();
        bean.setName("singleSignOutFilter");
        SingleSignOutFilter singleSignOutFilter = new SingleSignOutFilter();
        singleSignOutFilter.setSessionMappingStorage(new RedisBackedSessionMappingStorage(redisTemplate,sessionRepository));
        bean.setFilter(singleSignOutFilter);
        bean.addUrlPatterns("/*");
        bean.setEnabled(true);
        //bean.setOrder(Ordered.HIGHEST_PRECEDENCE);
        return bean;
    }
}
```
