Idea link to the mysql database, see the reference link 1 below. One thing to note, if the database does not set the global serverTimeZone, an error is reported here, and then go to which setting page Advanced where the item is written as Asia / Shanghai and it is ok. After idea is connected, it can be on the right see the results shown in Figure
and then try the connection does not solve the problem (this step is just awkward XD played a database connection tools, feel this function integrates some of the features of datagrip), find other ways
key is being given this sentence:
reference Link 2 also lists several possible errors. . . Nor is it
reference link 3 finally resolved, which is considered a very low-level error. . .
Wrong way of writing when writing SqlMapConfig.xml
<property name="url" value="jdbc:mysql//localhost:3306/mybatis_test"/>
Write it correctly and pay attention to the colon. . .
<property name="url" value="jdbc:mysql://localhost:3306/mybatis_test"/>
It is a lesson and a summary of no suitable driver found for jdbc
In addition, if the database does not set the global serverTimeZone, an error may be reported here. A simple solution is to add some parameters (including time zone) after the url?
<property name="url" value="jdbc:mysql://localhost:3306/mybatis_test?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT"/>
There is also a place to note that the & in the xml must be written as & otherwise an error
will be reported here and then changed:
<property name="url" value="jdbc:mysql://localhost:3306/mybatis_test?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT"/>
Here I have solved all the problems related to the idea database and mybatis database configuration. The summary is as follows:
- Mybatis appeared to solve the jdbc configuration problem and let users focus more on the problem itself, but the configuration process needs to be careful (also the reason why I am not familiar with the configuration, use it or lose it, slowly become familiar with)
- The url in the configuration file SqlMapConfig.xml needs to pay attention to "mysql:" of ":"
- ";" in the xml file needs to be replaced with "&"
