[Solved] JAVA:java.lang.ClassNotFoundException: sun.jdbc.odbc.JdbcodbcDrive

The reason for this problem is that the class can not be found. The following code is normal. It can run in JDK1.6. Oracle has canceled the ODBC bridge after JDK1.6. The solution is to change another driver mode. The current SQL Server driver is com.microsoft.sqlserver.jdbc.sqlserverdriver, and the connection string is jdbc:sqlserver :// localhost:1433; Databasename = database name

/**
 * Author：C
 * Date: 03/15/2020
 * Demonstrate the use of jdbc-odbc bridge to operate the database
 * 1. Configure the data source
 * 2. Connect to the data source in the program
