spring-boot 分佈式session

• 父級pom配置

<!--Spring Cloud 相關依賴-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-dependencies</artifactId>
        <version>${spring-cloud.version}</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>

• pom配置

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

• yml配置文件

redis:
    host: 192.168.232.198
    port: 6379
    password: # Redis服務器地址
    timeout: 5000ms
    lettuce:
      pool:
        max-active: 8
        max-wait: -1ms
        max-idle: 8
        min-idle: 0
  session:
    store-type: redis

• 代碼使用

public class BaseController {

    public HttpServletRequest getRequest(){
        return ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
    }

    public HttpServletResponse getResponse(){
        return ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getResponse();
    }

    public HttpSession getHttpSession(){
        return getRequest().getSession();
    }

}

//登陸接口設置session
getHttpSession().setAttribute("member", member);

//攔截器獲取session 
request.getSession().getAttribute("member")

• redis 配置

@Configuration
public class RedisConfiguration {

    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory){
        RedisTemplate<String,Object> template = new RedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
        /*
         * 序列化後會產生java類型說明，如果不需要用“Jackson2JsonRedisSerializer”
         * 和“ObjectMapper ”配合效果更好
         */
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(Object.class);

        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);

        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        template.setKeySerializer(stringRedisSerializer);
        template.setValueSerializer(jackson2JsonRedisSerializer);

        template.setHashKeySerializer(stringRedisSerializer);
        template.setHashValueSerializer(jackson2JsonRedisSerializer);

        template.afterPropertiesSet();
        return template;
    }

}

• RedisHttpSessionConfiguration

@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 3600)
public class RedisHttpSessionConfiguration {
    /**
     * 引入分佈式會話體系,會話內容存儲在Redis當中,原理請閱讀源碼
     */

}
