直接在IDEA运行Jar包没问题，但用java -jar 的命令就报错是为什么？
对应代码：
@Bean
public RedissonClient getRedissonClient() {
// 1.创建配置对象
Config config = new Config();
// 添加单机Redisson配置
config.useSingleServer()
// 设置数据库
.setDatabase(database)
// 设置redis的地址
.setAddress("redis://" + host + ":" + port)
// 设置redis的密码(redis有密码才设置)
.setPassword(password);
// 2.创建Redisson实例
RedissonClient redisson = Redisson.create(config);
return redisson;
}报错原因如下，是在创建Redisson客户端的时候报错：

网上说是JDK9以上多模块的原因，但我是JDK8啊
java
就是你的依赖库有问题，或者运行环境配置毛病。我看AI比我说的还清楚，估计这也是没什么大佬来回答这个问题的原因吧。祝你顺利！
