springboot实现session共享(redis中保存)

模拟测试:建立两个模块,一个保存session到redis中,一个从redis中获取session的value值

模块相同部分:

1.pom

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--  引入springboot&redis整合场景  -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
        <!--  引入springboot&springsession整合场景  -->
        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
        </dependency>

2.yml

spring:
  redis:
    host: 127.0.0.1
  session:
    store-type: redis
server:
  port: ? (此处为唯一不同地方,模块需要不同的port)

模块一: 保存session到redis

@RestController
public class HelloHandler {
    @RequestMapping("/test/spring/session/save")
    public String testSession(HttpSession session) {

        session.setAttribute("king", "hello-king");

        return "数据存入Session域！";
    }
}

测试数据如下: 可以看出数据已经保存到redis里面了

127.0.0.1:6379> keys *
1) "spring:session:expirations:159815802
2) "spring:session:sessions:expires:f67d
3) "spring:session:sessions:f67d16f2-851
127.0.0.1:6379> type spring:session:sess
0
hash
127.0.0.1:6379> hgetall spring:session:s
2320
1) "lastAccessedTime"
2) "xacxedx00x05srx00x0ejava.lang.
01Jx00x05valuexrx00x10java.lang.Numb
00x00xpx00x00x01tx19x88x1dxb6"
3) "maxInactiveInterval"
4) "xacxedx00x05srx00x11java.lang.
x00x01Ix00x05valuexrx00x10java.lan
x02x00x00xpx00x00a"
5) "sessionAttr:king"
6) "xacxedx00x05tx00
hello-king"
7) "creationTime"
8) "xacxedx00x05srx00x0ejava.lang.
01Jx00x05valuexrx00x10java.lang.Numb
00x00xpx00x00x01tx19x88x1dxb6"

模块二: 从redis获取session

@RestController
public class HelloHandler {
    @RequestMapping("/test/spring/session/retrieve")
    public String testSession(HttpSession session) {

        String value = (String) session.getAttribute("king");

        return value;
    }
}

结果第一次报错:端口号不安全

更改后可以得到数据:
