1.新增Maven依賴

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>2.5.0</version>
</dependency>

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
    <exclusions>
        <exclusion>
            <groupId>io.lettuce</groupId>
            <artifactId>lettuce-core</artifactId>
        </exclusion>
    </exclusions>
</dependency>

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
</dependency>
 

2.自定義RedisConfig

@Configuration
public class RedisConfig extends CachingConfigurerSupport {
    @Value("${spring.redis.host}")
    private String host;
    @Value("${spring.redis.port}")
    private int port;
    @Value("${spring.redis.password}")
    private String password;
    @Value("${spring.redis.timeout}")
    private int timeout;

    @Bean
    public JedisPool redisPoolFactory() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        return new JedisPool(jedisPoolConfig, host, port, timeout, password);
    }

    @Bean(name = "redisTemplate")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, Visibility.ANY);
        objectMapper.enableDefaultTyping(DefaultTyping.NON_FINAL);

        Jackson2JsonRedisSerializer<Object> jsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
        jsonRedisSerializer.setObjectMapper(objectMapper);
        redisTemplate.setDefaultSerializer(jsonRedisSerializer);

        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
}

application.properties關於Redis配置
spring.redis.host=182.92.234.232
spring.redis.port=6379
spring.redis.password=
spring.redis.timeout=2000
 

3.自定義RedisSessionConfig

@Configuration
@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 300)
public class RedisSessionConfig {
}

4.定義測試Controller

@RestController
public class TestController {

    @RequestMapping(value = "/sessionInfo", method = RequestMethod.GET)
    public Map<String, String> addSession (HttpServletRequest request){
        String sessionId = request.getSession().getId();
        String requestURI = request.getRequestURI();

        Map<String, String> sessionInfoMap = new HashMap<>(2);
        sessionInfoMap.put("sessionId", sessionId);
        sessionInfoMap.put("requestURI", requestURI);
        return sessionInfoMap;
    }
}
 

5.測試

開啟2臺tomcat(域名要相同 埠可以不同)，同一個瀏覽器session共享 具體可以看sessionId值
