spring-boot - 为休眠二级缓存 RegionFactory 重用 RedissonClient bean

问题描述

我有一个使用休眠（5.4.15.Final）和spring-session-data-redis的spring boot（2.3.0.RELEASE）应用程序。会话使用redisson持久化到 redis 。Redisson 客户端以编程方式创建并作为 Bean 公开。

有没有办法重新使用上面的bean。

我试过的：

我创建了以下类，它尝试通过扩展 RedissonRegionFactory 来注入RedissonClient

@DependsOn("redis-client")
public class RedissonCachingConfiguration extends RedissonRegionFactory {
    private RedissonClient redissonClient;

    @Autowired
    public RedissonCachingConfiguration(RedissonClient redissonClient) {
        this.redissonClient = redissonClient;
    }

    @Override
    protected RedissonClient createRedissonClient(Map properties) {
        return redissonClient;
    }
}

但是RedissonClient在构造函数中为 null 并抛出以下堆栈跟踪。

它看起来正在尝试调用无参数构造函数，但没有。我尝试使用 setter 注入添加无参数构造函数，但未注入客户端。
