Bean工具类（可以在工具类中使用springboot的配置）

@Service
public class BeanUtil implements ApplicationContextAware {private static ApplicationContext context;@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {context = applicationContext;}public static <T> T getBean(Class<T> beanClass) {return context.getBean(beanClass);}
}

filter(用来进行后台接口请求的验证)

// 与redis的数据进行比较
if (SecurityUtils.getUserid() != null) {String userId = SecurityUtils.getUserid().toString();String key = RedisPreEnum.JWT_TOKEN_PRE.getPre() + userId + IpUtils.getIpAddr(request);RedisUtil redisUtil = BeanUtil.getBean(RedisUtil.class);if (redisUtil.hasKey(key)) {Object o = redisUtil.get(key);}
}
else {// do nothing.
}

redis枚举类

/*** redis key前缀*/
@AllArgsConstructor
@Getter
public enum RedisPreEnum {JWT_TOKEN_PRE("JWT_TOKEN_","token前缀",60*60*24);private String pre;private String desc;private Integer expired;
}

ip工具类

public class IpUtils {//客户端类型  手机、电脑、平板//UserAgent userAgent = UserAgent.parseUserAgentString(request.getHeader("user-agent"));//String clientType = userAgent.getOperatingSystem().getDeviceType().toString();//操作系统类型//String os = userAgent.getOperatingSystem().getName();//请求ip//String ip = IpUtils.getIpAddr(request);//浏览器类型//String browser = userAgent.getBrowser().toString();public static String getIpAddr(HttpServletRequest request) {String ip = request.getHeader("x-forwarded-for");if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("X-Real-IP");//LOGGER.error("X-Real-IP:"+ip);}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("http_client_ip");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getRemoteAddr();}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("WL-Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("HTTP_X_FORWARDED_FOR");}// 如果是多级代理，那么取第一个ip为客户ipif (ip != null && ip.contains(",")) {ip = ip.substring(ip.lastIndexOf(",") + 1, ip.length()).trim();}return ip;}
}

登录服务（独立微服务，调用工具类）

application.yml

 redis:# Redis数据库索引（默认为0）database: 0# Redis服务器地址host: 127.0.0.1# Redis服务器连接端口port: 6379# Redis服务器密码，可选.# password: 123456# jedis配置jedis:pool:# 连接池最大连接数（使用负值表示没有限制）max-active: 100# 连接池中的最大空闲连接max-idle: 10# 连接池中的最小空闲连接min-idle: 0# 连接池最大阻塞等待时间（使用负值表示没有限制）max-wait: 100000# 连接超时时间（毫秒）timeout: 5000

配置代码

此处会读取application.yml的配置信息

@Configuration
@ConditionalOnClass(RedisOperations.class)
@EnableConfigurationProperties(RedisProperties.class)
public class RedisConfig {@Bean@ConditionalOnMissingBean(name = "redisTemplate")public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {RedisTemplate<Object, Object> template = new RedisTemplate<>();//使用fastjson序列化FastJsonRedisSerializer fastJsonRedisSerializer = new FastJsonRedisSerializer(Object.class);// value值的序列化采用fastJsonRedisSerializertemplate.setValueSerializer(fastJsonRedisSerializer);template.setHashValueSerializer(fastJsonRedisSerializer);// key的序列化采用StringRedisSerializertemplate.setKeySerializer(new StringRedisSerializer());template.setHashKeySerializer(new StringRedisSerializer());template.setConnectionFactory(redisConnectionFactory);return template;}@Bean@ConditionalOnMissingBean(StringRedisTemplate.class)public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory redisConnectionFactory) {StringRedisTemplate template = new StringRedisTemplate();template.setConnectionFactory(redisConnectionFactory);return template;}
}

登录部分保存缓存的代码

// 存入redis缓存
String ipAddr = IpUtils.getIpAddr(request);
String key = RedisPreEnum.JWT_TOKEN_PRE.getPre() + user.getId().toString();
Set<String> keys = redisUtil.keys(key+"*");
if (CollectionUtils.isEmpty(keys)) {redisUtil.set(key+ipAddr,user,RedisPreEnum.JWT_TOKEN_PRE.getExpired());
}
else {//清空之前的keyfor (String k:keys) {redisUtil.del(k);}//重新设置keyredisUtil.set(key+ipAddr,user,RedisPreEnum.JWT_TOKEN_PRE.getExpired());
}
