“NoClassDefFoundError：javax / xml / bind / DatatypeConverter”使用SQL Server JDBC [英] "NoClassDefFoundError: javax/xml/bind/DatatypeConverter" with SQL Server JDBC

问题描述

我最近切换到了intellij，但我发现很难连接到我的localDB。相同的代码适用于eclipse。 此外，我已将sqljdbc42.jar添加为模块依赖项。

I recently switched to intellij but I'm finding it hard to connect to my localDB. The same code worked on eclipse fine. Also I have already added the sqljdbc42.jar as a module dependency.

package com.enter;
import java.sql.*;

public class SqlConnect {
    private String username, password, url;
    public Connection conn;

    public SqlConnect() {
        username = "user=admin;";
        password = "password=admin";
        url = "jdbc:sqlserver://Bossman-PC\\SQL2014TRAINING;databaseName=EnterDB;";
        Connect();
    }
    public SqlConnect(String user, String pass) {
        username = user;
        password = pass;
        url = "jdbc:sqlserver://Bossman-PC\\SQL2014TRAINING;databaseName=EnterDB;";
        Connect();
    }

    public void Connect() { //Loads sql driver and creates a connection object with local database
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            String connectionUrl = url + username + password;
            conn = DriverManager.getConnection(connectionUrl);
            System.out.println("Connected.");
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

    public Connection getConnection() {
        return conn;
    }


}

产生错误：

任何帮助将不胜感激。我也尝试过重载的DriverManager.getConnection（url，user，pass）方法和同样的错误。

Any help would be greatly appreciated. I've also tried the overloaded DriverManager.getConnection(url, user, pass) method and same error.

推荐答案

如前所述微软在 GitHub ：

目前我们的驱动程序发布的Jars都没有与JDK9兼容。

Currently none of our driver released Jars are compatible with JDK9.

你可以切换到使用Java 8 JDK，也可以将Microsoft的开发代码从他们的'JDBC4.3'分支合并到您的项目中，并将其与Java 9 JDK一起使用。

You can either switch to using the Java 8 JDK, or you can incorporate Microsoft's development code from their 'JDBC4.3' branch into your project and use that with the Java 9 JDK.
