spring boot session

spring boot中如何使用session？

1、配置文件中引入相关jar包

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

2、添加配置class

@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 1800)
public class SessionConfig {
   @Value("${redis.hostname:localhost}")
   String HostName;
   @Value("${redis.port:6379}")
   int Port;
   @Bean
   public JedisConnectionFactory connectionFactory() {
      JedisConnectionFactory connection = new JedisConnectionFactory();
      connection.setPort(Port);
      connection.setHostName(HostName);
      return connection;
   }
}

3、使用session

public Map<String, Object> Logout(HttpServletRequest request) throws Exception {
   Map<String, Object> resultMap = new HashMap<>();
   try {
      HttpSession session = request.getSession();
      session.removeAttribute("userName");
      session.removeAttribute("id");
   } catch (Exception e) {
   }
   return resultMap;
}
