提问by Ahmed Tawila
While trying to connect to MySQL database using Spring Boot, I am getting the following stacktrace:
在尝试使用 Spring Boot 连接到 MySQL 数据库时，我收到以下堆栈跟踪：

I tried all of the solutions for similar problems here but none of them seem to work.
我在这里尝试了所有类似问题的解决方案，但似乎没有一个有效。

You need to provide the port along with server IP.
您需要提供端口和服务器 IP。
Other parameters like autoReconnect & useSSL are optional.
其他参数如 autoReconnect 和 useSSL 是可选的。
You can use below connection string
您可以使用以下连接字符串
jdbc:mysql://localhost:3307/app
jdbc:mysql://localhost:3307/app
回答by Ahmed Tawila
I found that the connection string was messed up. Changing the connection string to jdbc:mysql://localhost:3307/app?autoReconnect=true&useSSL=falsefixed the issue
我发现连接字符串搞砸了。更改连接字符串以jdbc:mysql://localhost:3307/app?autoReconnect=true&useSSL=false解决问题
回答by Vinay
I had a similar issue. Following statement (after sudo mysql -p) alone did not work:
我有一个类似的问题。以下语句（在 sudo mysql -p 之后）单独不起作用：
mysql> create user 'user1'@'localhost' identified by '********';
Had to also add:
还必须补充：
mysql> create user 'user1'@'127.0.0.1' identified by '********';
Optionally one may consider executing this as well:
可选地，也可以考虑执行此操作：
mysql> grant all privileges on thisdb.* to 'user1'@'127.0.0.1' identified by '*********';
Then it worked.
然后它起作用了。
