pom依赖（快照版）：

　　　　　　　　　　<dependency>
		    <groupId>org.springframework.session</groupId>
		    <artifactId>spring-session</artifactId>
		</dependency>
		<dependency>
		    <groupId>org.springframework.data</groupId>
		    <artifactId>spring-data-redis</artifactId>
		</dependency>
		<dependency>
		    <groupId>biz.paluch.redis</groupId>
		    <artifactId>lettuce</artifactId>
		    <version>5.0.0.Beta1</version>
		</dependency>
		<dependency>
		    <groupId>io.projectreactor</groupId>
		    <artifactId>reactor-core</artifactId>
		    <version>3.0.6.RELEASE</version>
		</dependency>

　　RedisSession.java

@EnableRedisHttpSession
@EnableConfigurationProperties(RedisProperties.class)
public class RedisConfiguration {

	@Resource
	private RedisProperties redisProperties;

	@Bean
	public LettuceConnectionFactory connectionFactory() {
		LettuceConnectionFactory factory = new LettuceConnectionFactory();
		factory.setHostName("localhost");
		factory.setPassword("redispassword");
		factory.setDatabase("0");
		factory.setTimeout(5000);
		factory.setPort(6379);
		return factory;
	}

}

　　然后在把值放入到HttpSession里面就会被自动放入到redis里面了。在集群下自动达到共享session的功能。

如：

　　public ResponseEntity<Object> browseCunAction(@RequestParam("key")String key,@RequestParam("value")String value,HttpSession session) throws Exception {
		session.setAttribute(key, value);
		return ResponseEntity.ok(Collections.singletonMap(key, value));
	}
