SQL Server JDBC的“NoClassDefFoundError:javax / xml / bind / DatatypeConverter”
作者:互联网
我最近切换到intellij,但我发现很难连接到我的localDB.相同的代码适用于eclipse.此外,我已经添加了sqljdbc42.jar作为模块依赖项.
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;
}
}
出错:

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.
解决方法:
正如微软在GitHub所述:
Currently none of our driver released Jars are compatible with JDK9.
您可以切换到使用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.
