【已解决】黑马点评启动 Redisson报错

1. 解决

原因是你的Redis虽然正确启动了，但是你的Redis有密码，所以在Redisson实例化的时候需要配置，在黑马点评项目里的config/RedissonConfig.java中增加setPassword("密码")进行配置。

@Bean
public RedissonClient redissonClient() {
	Config config = new Config();// 创建一个新的 Config 对象，用于配置 Redisson。
	// 根据配置创建并返回 RedissonClient 实例。
	//        config.useSingleServer()：指定使用单节点模式连接 Redis。
	//        Redisson 支持多种模式，包括单节点、集群、哨兵等模式。这里选择单节点模式。
	config.useSingleServer()// 说明当前用的是单节点的redis
		.setAddress("redis://localhost:6379").setPassword("123456");
	// 根据配置创建并返回 RedissonClient 实例。
	return Redisson.create(config);
}
