최근에 intellij로 전환했지만 localDB에 연결하는 것이 어렵습니다. 같은 코드가 일식 잘 작동했습니다. 또한 모듈 종속성으로 sqljdbc42.jar를 이미 추가했습니다. 생산"NoClassDefFoundError : javax/xml/bind/DatatypeConverter"with SQL Server JDBC
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;
}
}

컴파일러가 Intellij를 사용 했습니까? Intellij로 전환하면 내 프로젝트 ** 언어 수준 **이 항상 1.5로 설정됩니다. ** 모듈 설정 **을 열고 올바른 언어 수준으로 변경하면 도움이됩니다. – haifzhan
예 모듈 종속성으로 Java 9 JDK 및 sqljdbc42가 있습니다. –
