如何捕获从oracle到java的自定义异常

CREATE OR REPLACE EXCEPTION custom_exception
    FOR MY_CUSTOM_ERROR_CODE
    'This is a custom exception';

import java.sql.*;

public class OracleExceptionExample {
    public static void main(String[] args) {
        String url = "jdbc:oracle:thin:@localhost:1521:xe";
        String username = "your_username";
        String password = "your_password";

        try {
            Connection connection = DriverManager.getConnection(url, username, password);
            Statement statement = connection.createStatement();

            // Execute SQL query
            ResultSet resultSet = statement.executeQuery("SELECT * FROM your_table");

            while (resultSet.next()) {
                // Process the results
            }

            resultSet.close();
            statement.close();
            connection.close();
        } catch (SQLException e) {
            if (e.getErrorCode() == MY_CUSTOM_ERROR_CODE) {
                // Handle custom exception
                System.out.println("Custom exception caught: " + e.getMessage());
            } else {
                // Handle other exceptions
                e.printStackTrace();
            }
        }
    }
}
