无法通过 SSL 连接使用 JOOQ 和 MySQL 数据库生成代码

【问题标题】：Can't generate code with JOOQ and MySQL Database over SSL connection无法通过 SSL 连接使用 JOOQ 和 MySQL 数据库生成代码
【发布时间】：2014-08-01 11:37:41
【问题描述】：

我正在尝试从我通过 SSL 连接到的 MySQL 数据库生成代码。我从建立数据库的人那里得到了 3 个文件（client-cert.pem、client-key.pem、ca-cert.pem）

要使用 Java 连接到数据库，我首先必须解决证书的另一个问题。在http://bugs.mysql.com/bug.php?id=68957 的帮助和"[17 Apr 2013 9:04] Alexander Soklakov" 的帮助下，我设法让 JDBC 连接在我的 Java 代码中按预期工作。

但现在我不知道在 JOOQs library.xml 中的何处配置 SSL。我在哪里提供 *.pem 文件？还是我创建的信任和密钥库？没有配置 SSL 我得到了

当我查看http://www.jooq.org/xsd/jooq-codegen-2.5.0.xsd下的架构时，我也找不到任何提示

现在看来我不得不放弃使用 JOOQ :(

编辑：我使用 Eclipse 生成 JOOQ 代码，如“从 Eclipse 运行代码生成”下的http://www.jooq.org/doc/3.0/manual/code-generation/codegen-configuration/ 中解释的。

【问题讨论】：

  • 如果你从其他人那里得到了客户端密钥，你应该把它扔掉。这是不安全的。您应该生成自己的私钥。否则，它无法执行预期的功能。
  • 嗨，EJP。我的问题是，我有很大的时间限制，我不能过多地研究数据库主题——我真的不喜欢这样工作，但这次我被困住了。现在我只是想让它工作以保持我的最后期限......我从数据库所有者那里得到这些文件并认为，客户端密钥就像一个密码，我需要使用它。但我会尝试阅读更多关于 SSL 的内容 - 感谢您的提示，我使用错误并且理解错误。没有解决方案，但也是一个非常有价值的信息！

【解决方案1】：

如果您需要一种更特殊的方式来设置数据库连接，那么正确的前进方式可能是使用编程代码生成配置。这记录在这里：

http://www.jooq.org/doc/latest/manual/code-generation/codegen-programmatic/

我们（很遗憾）尚未明确记录这一点，但您可以通过调用 setConnection() 将 JDBC 连接明确传递给 GenerationTool

【讨论】：

  • 效果很好，谢谢 Lukas！我将使用现在对我有用的解决方案来扩展我的问题 - 供参考......
  • @Kai：很高兴看到它有帮助！请注意，在 Stack Overflow 上执行此操作的常用方法是为您的问题提供您自己的答案。这个问题的未来访问者将更容易理解您是如何实现您的解决方案的（顺便说一句，不错的解决方案）
  • 哦，我认为接受您的回答而不是我自己的回答会更好/更好，这将基于您的回答；）下次我会记住这一点。跨度>

【解决方案2】：

解决方案，基于 Lukas Eder 接受的答案

creating the truststore and keystore 之后（向下滚动到 [2013 年 4 月 17 日 9:04] Alexander Soklakov），我可以使用以下类生成代码，在其中我获得 SSL 数据库连接并将其用于 JOOQ 生成器：

import java.sql.Connection;

import org.jooq.util.GenerationTool;
import org.jooq.util.jaxb.Configuration;
import org.jooq.util.jaxb.Database;
import org.jooq.util.jaxb.Generator;
import org.jooq.util.jaxb.Target;

import com.mysql.jdbc.jdbc2.optional.MysqlDataSource;

public class JooqGenerator {

    public static void main(String[] args) throws Exception {

        MysqlDataSource mysqlDS = new MysqlDataSource();

        mysqlDS.setUseSSL(true);
        mysqlDS.setRequireSSL(true);

        mysqlDS.setClientCertificateKeyStoreUrl(".../keystore");
        mysqlDS.setClientCertificateKeyStorePassword("keystore-pw");

        mysqlDS.setTrustCertificateKeyStoreUrl(".../truststore");
        mysqlDS.setTrustCertificateKeyStorePassword("truststore-pw");

        mysqlDS.setServerName("server");
        mysqlDS.setPort(3306);
        mysqlDS.setDatabaseName("databasename");

        Connection connection = mysqlDS.getConnection("user", "password");

        Configuration configuration = new Configuration()
            .withGenerator(new Generator()
                .withName("org.jooq.util.DefaultGenerator")
                .withDatabase(new Database()
                    .withName("org.jooq.util.mysql.MySQLDatabase")
                    .withIncludes(".*")
                    .withExcludes("")
                     .withInputSchema("databasename"))
                .withTarget(new Target()
                    .withPackageName("my.package.name")
                    .withDirectory("./src")));

        GenerationTool tool = new GenerationTool();
        tool.setConnection(connection);
        tool.run(configuration);
    }
}
