eclipse用jdbc连接mysql数据库时，url是填什么？怎样找出地址？

1、首先登陆mysql，查看mysql的数据情况，select * from test_data1 t

2、新建java类，测试jdbc功能

3、编写java的jdbc代码，

String driver = "com.mysql.cj.jdbc.Driver"

String url = "jdbc:mysql://localhost:3306/testdb?characterEncoding=utf8&useSSL=false"

String user = "root"

String pwd = "123456"

4、代码中查询mysql数据表，并执行查出表中内容；select * from test_data1

mysql5.0

driver-class-name: com.mysql.jdbc.Driver

url: jdbc:mysql://localhost:3306/testspringboot?useSSL=false

mysql8.0

driver-class-name: com.mysql.cj.jdbc.Driver

url: jdbc:mysql://localhost:3306/testspringboot?useSSL=false&serverTimezone=UTC
