我正在尝试使用JDBC驱动程序建立与Sybase ASE 16.0的SSL连接。在服务器上,通过交互式SQL,我可以使用SSL访问ASE服务器。我正在将Jconnect 4(jconn4.jar)和JDK 8与以下连接字符串一起使用:jdbc:sybase:Tds:host:port / dbname?ENABLE_SSL = true。使用keytool将服务器证书导入到Java应用程序信任库中。我已经完成了operator precedence的操作,但这无助于我纠正此问题。测试代码如下。
public IActionResult GeStudents(GraduationStatus selectedGraduationStatus)
{
var graduates = db.Graduated_Students.Where(t=> t.GraduationStatus == selectedGraduationStatus);
return View(graduates.ToList());
}
我的JDBC代码抛出以下异常。 应该通过安全网络建立连接,但是面临以下错误。
try {
Class.forName("com.sybase.jdbc4.jdbc.SybDriver");
Connection con = DriverManager.getConnection(
"jdbc:sybase:Tds:host:5000/master?ENABLE_SSL=TRUE", "sa",
"password");
System.out.println("*********Connected**********");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("select @@ssl_ciphersuite");
int i = 1;
while (rs.next()) {
System.out.println("Row: " + i);
System.out.println("ID: " + rs.getString(1).trim());
System.out.println(" ");
i = i + 1;
}
con.close();
} catch (Exception e) {
e.printStackTrace();
}
我检查了Sybase日志,看到以下错误:
java.sql.SQLException: JZ00L: Login failed. Examine the SQLWarnings chained to this exception for the reason(s).

我浏览了多个Sybase文档,但是没有运气。任何帮助都感激不尽。在此先感谢!
