Step 1: Let's do the environmental preparations before the connection
1. First download the driver on the MySQL official website: (The download address blogger has sorted it out for everyone and uses it directly)
https://dev.mysql.com/downloads/file/?id=498587
down like this
2. Create a new project in eclipse
3. Add the driver to eclipse
Step 3: Select the jar file you just installed
Step Four: Success Stories
Step 5: Create a new class for testing
Click Finish
If successful, it will display:
I have written the specific code and can use it directly (the uploaded resources are self-collected for free)
Finished product:
pass: You will report an error when you copy it. The reason for the error is that the class is not exported
Solution: Click ctrl+shift+o to select the third
third step:
Open cmd and run as administrator:
Enter net start mysql to start the service. Here everyone’s service name is not uniform. Some people changed it later, but basically it is either mysql or mysql57. You can use services.msc to press Enter to check the specific name of the mysql service and start it again. If u root -p cannot be executed, it means that the environment variable is not configured properly. You can edit the environment variable and click the environment variable by yourself.
Environment variable method one:
Click path:
Paste the above address of your mysql installation bin and click OK
Method 2: Enter in the administrator cmd
MySQL Server Instance Config Wizard
In this way, it is more convenient to automatically configure environment variables locally (recommended)
Step 4: After the configuration is complete, you can use mysql -u root -p to enter the root user password and enter the mysql page
After that, you can execute mysql operations in cmd
Here I use the st database and the stu data table to give you a demonstration
Step 5: Go back to eclipse and follow the steps to start the code
Result: Finally, the data on mysql can be displayed on eclipse, and eclipse is also correctly connected to mysql at this time
The blogger here also uploads the eclipse installation package to the appendix for everyone to use for free. I wish you a happy experiment. If there is anything you don’t know, leave a message below, and I will reply when I see it
