springboot加@EnableRedisHttpSession注解后namespace配置失效

配置和注解是配置的两种方式，加注解后，

  public void setRedisNamespace(String namespace) {
        this.redisNamespace = namespace;
    }

该方法得不到调用，不加注解则SpringBootRedisHttpSessionConfiguration类

package org.springframework.boot.autoconfigure.session;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnBean;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.autoconfigure.session.SessionProperties.Redis;
import org.springframework.context.annotation.Conditional;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.session.SessionRepository;
import org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration;

@Configuration
@ConditionalOnClass({RedisTemplate.class})
@ConditionalOnMissingBean({SessionRepository.class})
@ConditionalOnBean({RedisConnectionFactory.class})
@Conditional({SessionCondition.class})
class RedisSessionConfiguration {
    RedisSessionConfiguration() {
    }

    @Configuration
    public static class SpringBootRedisHttpSessionConfiguration extends RedisHttpSessionConfiguration {
        public SpringBootRedisHttpSessionConfiguration() {
        }

        @Autowired
        public void customize(SessionProperties sessionProperties) {
            Integer timeout = sessionProperties.getTimeout();
            if (timeout != null) {
                this.setMaxInactiveIntervalInSeconds(timeout);
            }

            Redis redis = sessionProperties.getRedis();
            this.setRedisNamespace(redis.getNamespace());
            this.setRedisFlushMode(redis.getFlushMode());
        }
    }
}

会触发setRedisNamespace，当符合上面几个condition的时候会触发，如果加注解，则上面的
RedisOperationsSessionRepository会import，所以不满足

@ConditionalOnMissingBean({SessionRepository.class})

条件，不会触发自定义操作，加注解只能在注解里面加
