Spring-session+Redis解决Session共享

　　　1. 保证Redis启动
           2. 导入依赖
               SpringBoot+Spring-Session+Redis

<!--spring boot 与redis应用基本环境配置 -->

<dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-redis</artifactId></dependency> <!--spring session 与redis应用基本环境配置,需要开启redis后才可以使用，不然启动Spring boot会报错 --><dependency>    <groupId>org.springframework.session</groupId>    <artifactId>spring-session-data-redis</artifactId></dependency><dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-data-redis</artifactId></dependency>

            3. 配置大配置文件application.yml

server:　#port: 8080
  port: 8081

  #redis配置
  spring:
    redis:
      database: 0
      host: 127.0.0.1
      port: 6379
#      password: redis

controller

@RestController
public class SessionController {
    //存放Session值
    @RequestMapping("/setSession")
    public String setSession(HttpServletRequest request){
        request.getSession().setAttribute("username","zhangsan");
        return "success";
    }

    //获取Session值
    @RequestMapping("/getSession")
    public String getSession(HttpServletRequest request){
        return (String)request.getSession().getAttribute("username");
    }
}

在当前项目同时启动8080和8081端口

在8080端口set数据
