springboot使用redis管理session

源码地址

一 搭建工程

1. 添加依赖，贴上pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->

    <artifactId>redis-session</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>redis-session</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

2. 启动redis服务器，然后在项目配置文件添加以下内容

spring:
  redis:
    host: 127.0.0.1
    port: 6379
    password:

3. 贴上启动类

@SpringBootApplication
@EnableCaching
@EnableRedisHttpSession
@RestController
public class RedisSessionApplication {

    @Autowired
    private HttpSession session;

    public static void main(String[] args) {
        SpringApplication.run(RedisSessionApplication.class, args);
    }

    @GetMapping("/user/add")
    public String addUser() {
        session.setAttribute("user", "Jack");
        return "add Jack success !";
    }

    @GetMapping("/user/q")
    public String getUser() {
        Object user = session.getAttribute("user");
        return String.format("get %s from session success !",String.valueOf(user));
    }
}

二 测试

1. 启动项目，访问：http://localhost:8080/user/add
   
2. 访问：http://localhost:8080/user/q
   
3. 重启工程，直接访问：http://localhost:8080/user/q
   
   依然获取到了session结果，证明session是保存在redis中了
4. 贴上redis服务器保存session的截图
