java - Java 运行时环境检测到 fatal error - Microsoft SQL Server

Question

我有一个java应用程序应该连接到Microsoft SQL Server..我使用JRE 1.8和sqljdbc4-2.0.jar..当我尝试运行时:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000006f41dd27, pid=8404, tid=8960

我在网上搜索了这个错误，但没有找到任何东西..

这是我使用的代码:

    try {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
        String connectionUrl = "jdbc:sqlserver://localhost:1433;instance=SQLEXPRESS;databaseName=Mydatabase;integratedSecurity=true";
        con = DriverManager.getConnection(connectionUrl);
        System.out.println("Connected");
    } catch (ClassNotFoundException e) {
        throw new Exception("Driver Not Found");
    }

Answer 1

根据此网站Building the Connection URL您的连接字符串可能有问题。

jdbc:sqlserver://localhost:1433;instance=SQLEXPRESS;databaseName=Mydatabase;integratedSecurity=true

应该是:

jdbc:sqlserver://localhost;instanceName=SQLEXPRESS;databaseName=Mydatabase;integratedSecurity=true

(注意实例名称，而不是实例)

还有......

为了获得最佳连接性能，您应该在连接到命名实例时设置端口号。这将避免往返服务器以确定端口号。 如果同时使用端口号和实例名，则端口号优先，实例名将被忽略。

希望有帮助
