Recently, this bug has bothered me for two days. I can’t find the answer on the Internet, and it keeps telling me that there is no suitable driver to load. At first I thought that my database version is too high, or whether to consider changing to a lower version. The error report is as follows:
Exception in thread "main" org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause: java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/mybatis?serverTimezone=UTC&characterEncoding=utf-8
### The error may exist in com/Dao/UserDao.xml
### The error may involve com.Dao.UserDao.findAll
### The error occurred while executing a query
### Cause: java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/mybatis?serverTimezone=UTC&characterEncoding=utf-8

The test to connect to the database under Database showed that it was normal. When there was no problem,
I checked the code one by one. Finally, I found that I was really crying by myself, and the error I found was because of a ":" Problem:
Wrong wording:
<property name="url" value="jdbc:mysql//localhost:3306/mybatis?serverTimezone=UTC&characterEncoding=utf-8"/>
Correct writing: ( 注意冒号)
<property name="url" value="jdbc:mysql://localhost:3306/mybatis?serverTimezone=UTC&characterEncoding=utf-8"/>
It is a lesson and a solution summary of a no suitable driver found for jdbc. It also makes me pay more attention to these details in the future.
