Java如何获取JDBC驱动程序属性信息?

下面的示例向您展示如何获取有关相应JDBC驱动程序可能的属性的信息。

package org.nhooo.example.jdbc;

import java.sql.*;

public class DriverPropertyInfoDemo {
    private static final String URL = "jdbc:mysql://localhost/nhooo";

    public static void main(String[] args) {
        try {
            // 获取有关此属性的信息
            // 司机。
            Driver driver = DriverManager.getDriver(URL);
            DriverPropertyInfo[] props = driver.getPropertyInfo(URL, null);

            for (DriverPropertyInfo info : props) {
                System.out.println("Name       : " + info.name);
                System.out.println("Description: " + info.description);
                System.out.println("Value      : " + info.value);
                System.out.println("-----------------------------------");

                String[] choices = info.choices;
                if (choices != null) {
                    StringBuilder sb = new StringBuilder("Choices    : ");
                    for (String choice : choices) {
                        sb.append(choice).append(",");
                    }

                    System.out.println(sb.toString());
                }
            }

        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

上面的代码片段的示例结果:

Name       : HOST
Description: Hostname of MySQL Server
Value      : localhost
-----------------------------------
Name       : PORT
Description: Port number of MySQL Server
Value      : 3306

Name       : DBNAME
Description: Database name
Value      : nhooo
-----------------------------------
Name       : allowLoadLocalInfile
Description: Should the driver allow use of 'LOAD DATA LOCAL INFILE...' (defaults to 'true').
Value      : true
