Spring Session 和 redis 混合会话

Question

我们使用 redis 作为会话存储来配置 springsessions。随着更大的负载，它最终导致用户碰巧取回随机会话数据。

很遗憾，我们无法再次重现它，并且无法在测试环境中重现。

有没有人有类似的经历，或许可以指出看什么的方向？

我在我的项目中使用了redis session store的spring session如下，效果正常，分享一下，希望对你有帮助！

使用的 spring boot 启动器版本：1.4.3

Spring session redis 配置类：

package az.com.cybernet.aas.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.data.redis.connection.lettuce.
LettuceConnectionFactory;
import org.springframework.session.data.redis.config.annotation.web.http.
EnableRedisHt
tpSession;
import org.springframework.session.web.http.CookieHttpSessionStrategy;
import org.springframework.session.web.http.CookieSerializer;
import org.springframework.session.web.http.DefaultCookieSerializer;
import org.springframework.session.web.http.HttpSessionStrategy;



@EnableRedisHttpSession
public class RedisConfig {

@Value("${spring.redis.host}")
private String hostname;
@Value("${spring.redis.port}")
private String port;
// @Value("${spring.redis.password}")
// private String password;

@Bean
public LettuceConnectionFactory connectionFactory() {
    LettuceConnectionFactory connectionFactory = new LettuceConnectionFactory();
    connectionFactory.setHostName(hostname);
    // connectionFactory.setPassword(password);
    connectionFactory.setDatabase(2);
    connectionFactory.setPort(Integer.parseInt(port));
    return connectionFactory;
}

@Bean
public CookieSerializer cookieSerializer() {
    DefaultCookieSerializer serializer = new DefaultCookieSerializer();
    serializer.setCookieName("JSESSIONID");
    serializer.setCookiePath("/");
    serializer.setDomainNamePattern("^.+?\\.(\\w+\\.[a-z]+)$");
    return serializer;
}

@Bean
public HttpSessionStrategy strategy() {
    CookieHttpSessionStrategy cookieHttpSessionStrategy = new CookieHttpSessionStrategy();

    cookieHttpSessionStrategy.setCookieSerializer(cookieSerializer());
    return cookieHttpSessionStrategy;

}

}
