分布式session之token解决方案实现
基于令牌（Token）方式实现Session解决方案，因为Session本身就是分布式共享连接
用token代替session
废话不多说，看项目：

token的封装
package com.toov5.service; import java.util.UUID; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import ch.qos.logback.core.subst.Token; @Service public class TokenService { @Autowired private RedisService redisService; // 1 使用token方式替代session功能 //存入和获取 public String put(Object value){ //判断您是否为空 if (value == null) { return null; } // 先生成对应的token（token 实际上等于key） String token = getToken(); //存入在redis中 redisService.setString(token, value); //直接返回对应的token return token; } public String get(String token){ return redisService.getString(token); } public String getToken(){ return UUID.randomUUID().toString(); } }
controller
package com.toov5.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import com.toov5.service.TokenService; @RestController public class TestTokenController { @Autowired private TokenService tokenService; //使用token方式替代session sessiong服务器端创session 返回sessionid @RequestMapping("/put") public String put(String value){ String string = tokenService.put(value); System.out.println(string); return string; } //生成好的token如何存放？ 移动端存放本地文件 浏览器cookie @RequestMapping("/get") public String get(String object){ return tokenService.get(object); } //http如何传递？ 放在请求头里面 最好建议请求头里面 }
运行访问
怎么刷新都能获取到哦
redis 在服务器集群的时候 分布式缓存可以共享
