如何在python中测试jdbc连接？

import zxJDBC

# JDBC连接参数
driver = 'com.mysql.jdbc.Driver'
url = 'jdbc:mysql://localhost:3306/mydatabase'
username = 'myusername'
password = 'mypassword'

# 创建JDBC连接
conn = zxJDBC.connect(driver, url, username, password)

# 测试连接
if conn:
    print("JDBC连接成功！")
else:
    print("JDBC连接失败！")

# 关闭连接
conn.close()

pip install JayDeBeApi

import jaydebeapi

# JDBC连接参数
driver = 'com.mysql.jdbc.Driver'
url = 'jdbc:mysql://localhost:3306/mydatabase'
username = 'myusername'
password = 'mypassword'

# 创建JDBC连接
conn = jaydebeapi.connect(driver, url, [username, password])

# 测试连接
if conn:
    print("JDBC连接成功！")
else:
    print("JDBC连接失败！")

# 关闭连接
conn.close()
