使用pyspark在数据库中实现FileNotFound异常

from pyspark.sql import SparkSession
from pyspark.sql import SQLContext

spark = SparkSession.builder \
    .appName("FileNotFound Exception") \
    .getOrCreate()

sqlContext = SQLContext(spark)

# 配置数据库连接信息
url = "jdbc:mysql://localhost:3306/database_name"
properties = {
    "user": "username",
    "password": "password",
    "driver": "com.mysql.jdbc.Driver"
}

# 执行SQL查询
try:
    df = sqlContext.read.jdbc(url=url, table="table_name", properties=properties)
except Exception as e:
    if "FileNotFound" in str(e):
        print("FileNotFound Exception occurred.")
    else:
        print("Other exception occurred.")
