下面我们将在springcloud微服务项目中,使用redis实现简单高效的session共享。
了解springcloud架构可以加求求:三五三六二四七二五九

Redis Session配置类
package com.carry.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
@Configuration
@EnableRedisHttpSession
public class RedisSessionConfig {
}
控制层Controller中添加测试方法
package com.carry.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RefreshScope
public class UserManagementController {
/**
* redis sesion共享
*
* @param request
* @return
*/
@GetMapping("/getUser")
public String getUser(HttpServletRequest request) {
HttpSession session = request.getSession();
String username = (String) session.getAttribute("username");
if (StringUtils.isEmpty(username)) {
username = "testSessionRedis|" + System.currentTimeMillis();
session.setAttribute("username", username);
}
System.out.println("访问端口:" + request.getServerPort());
return username;
}
}
