DB2配置SSL访问-3、WEB配置JDBC支持DB2-SSL

DB2配置SSL访问-3、WEB配置JDBC支持DB2-SSL 配置 Java 运行时环境以使用 SSL

• 1.将证书从数据库服务器导入客户端上的 Java 信任库。
  使用 Java keytool实用程序将证书导入信任库。

示例：假设服务器证书存储在名为 mydbserver.arm 的文件中。发出以下keytool实用程序语句以从文件 mydbserver.arm 读取证书，并将其存储在名为 mynewdbclient.jks 的信任库中。

keytool -import -trustcacerts -alias myalias -file mydbserver.arm -keystore mynewdbclient.jks
输入密钥库口令:myClientPwd00
再次输入新口令:myClientPwd00

是否信任此证书? [否]:  是
证书已添加到密钥库中

• 2.java 代码：测试SSL方式连接DB2

import java.sql.*;
import java.util.Properties;

public class TestDb2SSL {
	public static void main(String[] args) {
		testSSLByUrl();
		testSSLByProperties();
	}

	
	private static void testSSLByProperties() {
		try {
			Class.forName("com.ibm.db2.jcc.DB2Driver").newInstance();

			String url = "jdbc:db2://192.168.5.131:60000/test";
			Properties prop = new Properties();
			prop.put("user", "db2inst1");
			prop.put("password", "DB2_2021");
			prop.put("sslConnection", "true");
			prop.put("sslTrustStoreLocation", "D:\DB2\ssl\mynewdbclient.jks");
			prop.put("sslTrustStorePassword", "myClientPwd00");

			System.out.println("测试通过属性参数连接数据库");
			Connection conn = DriverManager.getConnection(url, prop);
			System.out.println("连接正常! ");

			PreparedStatement ps = conn.prepareStatement("SELECt current timestamp AS T from sysibm.dual");
			ResultSet rs = ps.executeQuery();
			rs.next();
			System.out.println("T=" + rs.getObject(1));
			conn.close();
		} catch (Exception e) {
			System.out.print(e);
		}

	}

	
	private static void testSSLByUrl() {

		try {
			Class.forName("com.ibm.db2.jcc.DB2Driver").newInstance();

			String url = "jdbc:db2://192.168.5.131:60000/test:sslTrustStorePassword=myClientPwd00;sslTrustStoreLocation=D:\DB2\ssl\mynewdbclient.jks;sslConnection=true;";
			String user = "db2inst1";
