驱动程序无法通过使用 SSL 建立与 SQL Server 的安全连接

Question

我在连接到SQL数据库时遇到问题。每当我尝试连接到SQL server时，都会出现以下错误；

这是使用 com.microsoft.sqlserver.jdbc.SQLServerDriver

每当我使用JtDS驱动程序时（如本文所建议的），我仍然无法连接到SQL server，并出现以下错误。

我使用的连接字符串：（使用jtds）

jdbc： jtds：sqlserver://url.database.windows.net：[PORT]；数据库=名称；

或者不使用jtds时...

jdbc：sqlserver：//url.database.windows.net：[PORT];d atabase=name;

我还有一个服务器，它实际上能够使用这些配置运行并连接到数据库。我只是在本地连接数据库时不断遇到这些错误。

我正在运行macOS Sierra版本10.21

JTDS版本：

<dependency>
    <groupId>net.sourceforge.jtds</groupId>
    <artifactId>jtds</artifactId>
    <version>1.3.1</version>
</dependency>

sqlserver版本:

<dependency>
   <groupId>com.microsoft.sqlserver</groupId>
   <artifactId>sqljdbc4</artifactId>
   <version>4.0</version>
</dependency>

编辑：

我能够在不同的网络上使用相同的配置和相同的笔记本电脑连接到数据库。只有在我家里的网络上，我才会遇到这个错误

Answer 1

我怀疑，当您的笔记本电脑在“不同的网络”上时，防火墙内部也在保护您所连接的数据库服务器。因此，在这种情况下建立数据库连接没有问题。

我推测您的“家庭网络”位于防火墙之外，保护您尝试连接的数据库服务器。因此，由于防火墙保护，这种情况下的数据库连接尝试将被忽略。

如果这些假设正确，您将需要联系“不同网络”的网络管理员，以通过防火墙从您的家庭网络获得访问权限。

我希望这有所帮助。

Answer 2

你的问题类似于https://youtrack.jetbrains.com/issue/IDEA-163324

解决方案是：

• 打开终端
• run scutil --getHostName
• 如果主机名未设置或包含 .local，请运行 sudo scutil --set HostName ”

Answer 3

请将您的字符串url如下所示，并在项目中添加sqljdbc42.jar

url = "jdbc:sqlserver://" +serverName + ":1433;DatabaseName=" + dbName +";

encrypt = true;

trustServerCertificate=true;
