使用 RDS 2019 CA 根证书的 RDS PostgreSQL 的 Jetty + HikariCP + JVM SSL 连接问题

Question

我无法尝试使用 Jetty (9.4.26) + JVM (java-1.8.0)

连接到 RDS PostgreSQL

我尝试了一些东西

1. 将 2019 RDS CA 导入 Java cacerts
2. 为 Java
设置单独的 TrustStore 文件
3. 在 start.ini 中为 Jetty 设置 TrustStore 文件

打开 -Djavax.net.debug=ssl 显示已将 2015 RDS CA 添加到信任中，但我无法确定它被告知要信任的位置。我怀疑 webapp 嵌入了 2015 RDS CA...

来自 Jetty 的日志

(-Djavax.net.debug=ssl)

有什么想法吗？

Answer 1

我将尝试回答这个问题，因为我有一个有效的修复方法

修复正在升级 PostgreSQL JDBC 驱动程序。当前版本是 42.2.1，升级时可用的版本是 42.2.9

现在查看 Psql JDBS 驱动程序 changelog, I found that from version 42.2.5 onwards there was code change，它改变了 sslmode 使用的

查看JDBCdriver source，特别是在42.2.1版本的驱动程序中的ssl/MakeSSL.java文件中，这段代码现在已经不存在了

   33     SSLSocketFactory factory;
   34 
   35     String sslmode = PGProperty.SSL_MODE.get(info);
   36     // Use the default factory if no specific factory is requested
   37     // unless sslmode is set
   38     String classname = PGProperty.SSL_FACTORY.get(info);
   39     if (classname == null) {
   40       // If sslmode is set, use the libp compatible factory
   41       if (sslmode != null) {
   42         factory = new LibPQFactory(info);
   43       } else {
   44         factory = (SSLSocketFactory) SSLSocketFactory.getDefault();
   45       }
   46     } else {
   47       try {
   48         factory = (SSLSocketFactory) instantiate(classname, info, true,
   49             PGProperty.SSL_FACTORY_ARG.get(info));
   50       } catch (Exception e) {
   51         throw new PSQLException(
   52             GT.tr("The SSLSocketFactory class provided {0} could not be instantiated.", classname),
   53             PSQLState.CONNECTION_FAILURE, e);
   54       }
   55     }
