2023-05-27 22:24:50,130 ERROR [traceId=, spanId=] 2023-05-27 22:24:50 [main] [ERROR] - Application run failed
7.2 原因
Swagger2.9.2不支持WebFlux。
7.3 方案
使用Swagger3.0.0。
访问：

6 Win11安装WSL2及Ubuntu失败
Installing, this may take a few minutes…
WslRegisterDistribution failed with error: 0x80370114

方案
管理员执行终端：Win+X-》终端管理员

再次执行，安装成功。
查看版本：
wsl -l -v
5 git拥有者异常
commit时出现异常提示：
查看日志如下：
(fastapi-py310) PS D:\projects\py\python-tutorial> git log
fatal: detected dubious ownership in repository at ‘D:/projects/py/python-tutorial’
‘D:/projects/py/python-tutorial’ is owned by:
‘S-1-5-21-2994888592-1342716116-403010676-500’
but the current user is:
‘S-1-5-21-2994888592-1342716116-403010676-1001’
To add an exception for this directory, call:
git config --global --add safe.directory D:/projects/py/python-tutorial
(fastapi-py310) PS D:\projects\py\python-tutorial>
5.1 原因
笔记本无法联网，重装win11，
更换操作系统用户，git项目没有变更用户，导致用户前后不一致。
5.2 方案
修改git项目文件夹的用户。
找到项目文件夹，依次：右键->属性->安全->高级->更改等如下图操作。
注意：我配置的账户是个人账户，不是admin，因系统的当前用户而异。
4 Docker普通用户无权限
普通用户执行docker命令提示信息：
docker images
docker ps -a
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post “http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create?name=redis-module”: dial unix /var/run/docker.sock: connect: permission denied.
4.1 原因
当前用户不在Docker用户组。
4.2 方案
当前用户添加到用户组，由于只是个人操作的虚拟机，将当前用户添加到docker用户组。
$USER获取当前用户，如果是其他用户使用 $your-username。
# 添加用户组
sudo groupadd docker
# 主机用户添加到docker用户组
sudo gpasswd -a $USER docker
# 更新用户组
newgrp docker
3 Ubuntu22.04安装docker异常
Ubuntu22.04安装Docker出现如下异常，
因为，上次安装软件时使用了apt-get，中途中断安装。
sudo apt install docker.io
异常信息如下：
Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is hWaiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 1749 (unattended-upgr)
尝试删除文件：/var/lib/dpkg/lock-frontend
再次安装，异常信息如下：
E: Could not get lock /var/cache/apt/archives/lock. It is held by process 1749 (unattended-upgr)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to lock directory /var/cache/apt/archives/
再次删除相关文件：/var/cache/apt/archives/lock
即可正常安装。
3.1 原因
文件被中断的线程/服务占用，未被释放，无法读写。
3.2 方案
删除锁定的文件
sudo rm /var/lib/dpkg/lock-frontend
sudo rm /var/cache/apt/archives/lock

1.1 原因
缺少类：
1.2 方案
启动SpringBoot是排除该类。
@SpringBootApplication(exclude = SolrAutoConfiguration.class)
public class SearchApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(SearchApplication.class);
}
