Database-Connect to the database with IDEA

Database-Connect to the database with IDEA

Connection method: Use IDEA's own DATABASE plug-in

First open the database tool window from the menu View→Tool Windows→Database, as shown in the following figure: The subsequent operations are similar to Database Navigato

IDEA does not have its own DATABASE

1. Install the Database Navigato plugin

2. Connect to the database (take MySQL as an example)

3. After the connection is successful, Navigate will appear at the top, and DB Browser will appear on the left, and then click DB Browser on the left

4. Write SQL statements

Click the seventh button on the left, new consoles (note that the database to be operated is selected)

Solve the time zone problem when connecting (The server time zone)

Method 1: Add serverTimezone=GMT%2B8 to the properties configuration file

serverTimezone=GMT%2B8
url=jdbc:mysql://localhost:3306/jdbcstudy?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf8&useSSL=false

**方式二：打开命令行，设置MySQL时区为当前系统时区**
