java - 将 JDBC 驱动程序连接到 MSSQL 数据库时出现问题

标签 java sql eclipse jdbc jboss7.x

我们有一个 Java Web 应用程序，我遇到了一些 JDBC 问题。去年，在 Java 7 上，我们使用 sqljdbc4.jar 连接到同一网络上另一台服务器上的 SQL 数据库没有问题。今年我们将应用程序升级到了 Java 8，这就是问题出现的时候。我们将 JDBC 版本更新为 4.2 (sqljdbc42.jar)。 .jar 文件包含在我们的构建路径中，并且该文件在一年前有效。我们在 Eclipse-Luna IDE 中使用 JBOSS 7.0。

现在，当我们尝试使用 JDBC 时，我们会收到 java.lang.ClassNotFoundException。

Connection conn = null;
String db_hostname = "test.fake.com";
String db_portNumber = "1433";
String db_name = "db";
String db_userid = "user";
String db_password = "password";
String db_final_string = "jdbc:sqlserver://" + db_hostname + ":" + db_portNumber + ";databaseName=" + db_name;
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
conn = DriverManager.getConnection(_db_final_string, _db_userid, _db_password);

这是由于 Class.forName() 导致的错误:

如果任何人都可以提供有关如何正确配置此选项的任何见解，那将是最有帮助的，因为我们已经尝试了几种调整组合。

最佳答案

JBoss AS 7 与 Java 8 不兼容*。您需要更新到 WildFly 8/9 .
