LettuceConnectionFactory was destroyed and cannot be used anymore

（可跳过，成功率低）file->Invalidate Caches->Clear VCS log->Incalidate and Restart，然后重启项目

若上述未解决，直接重启电脑再次进入项目后可正常运行。

原因：网上有说法是redis连接方案的问题。

清除缓存后项目一直卡在indexing......

打开C盘 -> 用户 -> 用户名 -> AppData -> Local -> JetBrains -> IntelliJIedaxxxx.x，在这个目录下删除caches和index两个文件夹，然后重启idea。我在这里执行一次没有效果，弄了三次恢复了。

RESP连接失败

虚拟机关闭防火墙：systemctl stop firewalld

No qualifying bean of type ' ' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

因为使用mp忘记为Service接口添加实现类

idea新建包不分层

点击左侧导航栏顶部与Project同行的设置按钮 -> TreeAppearance -> 取消Compact Middle Packages

com.intellij.util.io.PersistentEnumeratorBase$CorruptedException: PersistentEnumerator storage

(idea2021)C:\Users\当前用户\AppData\Local\JetBrains\IntelliJIdea2021.3\compile-server

打开上述路径，删除出现错误的项目文件夹后再次重启idea。

ps：重启报错，因为idea未构建完成重启，导致文件损失。

Cannot delete or update a parent row: a foreign key constraint fails 

关闭外键约束检查 => SET foreign_key_checks = 0;  
执行删除或更新命令 => detele from table where ;
开启外键约束检查 => SET foreign_key_checks = 1;

ps:数据或表拥有主外键关系

再次点击install即可

Host  192.168.163.1  is not allowed to connect to this MySQL server.

1.mysql -u root -p，进入mysql客户端

2. use mysql; 

3.输入 SELECT Host, User, authentication_string FROM mysql.user;

4.update user set authentication_string=PASSWORD('123456'),plugin='mysql_native_password' where user='root';

连接成功

mysql登录报错ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: YES)，忘记密码

1.输入打开vim /etc/my.cnf文件，在[mysqld]下一行添加：skip-grant-tables（登录时跳过权限检查）

2.重启MySQL服务：sudo systemctl restart mysqld

3.修改密码

输入mysql -u root -p；登录mysql

输入：set password for ‘root’@‘localhost’=password(‘xxxx’);

(出现：ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement  输入：flush privileges;  再次输入：set password for ‘root’@‘localhost’=password(‘xxxx’);)

4.exit退出

启动MySQL出现：Redirecting to /bin/systemctl start mysqld.service Failed to start mysqld.service: Unit not found.

虚拟机MySQL一直出现（注意：这里是循环出现这个问题，如果是第一次只用使用：docker rm 容器ID（那一串数字））：docker: Error response from daemon: Conflict. The container name "/mysql" is already in use by container "946e100d8cbf1825a36619dcc16c2c2b4e7bfd31781cd408ecf0e31e5d52a0dd". You have to remove (or rename) that container to be able to reuse that name.

经过一下午的rm，才查询到原因是MySQL开启了进程守护，就会一直占用，杀不完，根本杀不完，所以只用执行一句语句就好，关闭MySQL进程守护:

service mysqld stop

io.lettuce.core.RedisCommandExecutionException: ERR Client sent AUTH, but no password is set

Redis密码错误或者无密码，首先打开redis目录下redis.windows.conf找到requirepass去掉#并加入密码。保存后进入redis使用cmd命令redis-server.exe redis.windows.conf重启，再次运行成功。

错误: 不支持发行版本 17

确定Project Setting中Project、Modules和Settings中Bulieder下java Compiler、Maven中jdk的版本都是17

ERR Client sent AUTH, but no password is set

浏览器无法访问rabbitmq

宿主机无法访问VMware虚拟机中的Docker启动的RabbitMQ的15672端口_宿主机访问不到docker启动的mq服务 怎么办-优快云博客 先使用 docker ps 查看rabbitmq的容器是否开启

若未开启 docker start 容器id/名字 打开开启容器

如果遇到如下问题：

可参考下面解决，本人使用第三个开启docker守护程序解决：
