自定义提供程序中的redis错误，java。lang.NoClassDefFoundError:无法初始化类组织。雷迪森。配置。配置

Question

我已经创建了这个dropwizard项目，我正在尝试使用Config（）为其添加Redisson客户端。redis的版本是3.8.1。以下是创建redis对象的自定义代码：

@Provides
@Singleton
public RedissonClient getRedissonClient() {
    final RedisConfig redisConfig = configuration().getRedisConfig();
    return redisConfig.isRedisActive() ? Redisson.create(new RedisConnectionBuilder(redisConfig).build()) : null;
}

//RedisConnectionBuilder.java
public RedisConnectionBuilder(final RedisConfig configuration) {
   redisConfig = configuration;
}
public Config build() {
        return redisConfig.getEndpoints().length > 1
                ? getReplicatedServersConfig()
                : getSingleServerConfig();
    }  
private Config getSingleServerConfig() {
        final Config config = new Config();
        config.useSingleServer()
                .setAddress(redisConfig.getEndpoints()[0])
                .setTimeout(redisConfig.getTimeout())
                .setIdleConnectionTimeout(redisConfig.getMaxIdle())
                .setConnectionPoolSize(redisConfig.getMaxTotal());

        return config;
    }

在运行代码时，我得到以下错误：

Error in custom provider, java.lang.NoClassDefFoundError: Could not initialize class org.redisson.config.Config
