用Windows身份验证连接查询数据库
Java eclipse → SQL Server 2016
0.0 如果没有下载sqljdbc,则先下载噢!链接如下(Microsoft官网滴!):Download Microsoft SQL Server JDBC 驱动程序 6.0 from Official Microsoft Download Centerhttps://www.microsoft.com/zh-cn/download//confirm/iation.aspx?id=11774
一般选第三个下载噢:
1.问题: 2.原因:没有为集成身份验证配置驱动程序
3.解决:找到下载的sqljdbc压缩包:
注意:x64表示64位,x86表示32位,根据自己电脑实际情况选择(我的电脑是Win10---64位)——如果电脑是64位 *** 作系统则复制auth下的x64文件夹的文件,如果电脑是32位 *** 作系统则复制auth下的x86文件夹的文件
注意:绝对路径是"C:WindowsSystem32sqljdbc_auth.dll"
4.解决啦: 5.附上完整代码供借鉴参考:java(eclipse)中连接java和SQL server的代码:
package test_jdbc;
import java.sql.*;
public class Test_connectURL {
public static void main(String[] args) {
// Create a variable for the connection string.
String connectionUrl = "jdbc:sqlserver://localhost:1433;DatabaseName=LibraryDB;integratedSecurity=true;"; //DatabaseName=自己的数据库名称;integratedSecurity=true表示使用Windows身份验证
// Declare the JDBC objects.
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
try {
// Establish the connection.
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con = DriverManager.getConnection(connectionUrl);
// Create and execute an SQL statement that returns some data.
String SQL = "SELECt * FROM Student"; //写自己需要的查询语句噢
stmt = con.createStatement();
rs = stmt.executeQuery(SQL);
System.out.println("学号t姓名t信用度"); //写自己需要的标题噢
// Iterate through the data in the result set and display it.
while (rs.next()) {
System.out.println(rs.getString("Sno") + "t" + rs.getString("Sname") + "t" + rs.getString("Credit")); //根据自己查询的内容结果写打印内容噢
}
}
// Handle any errors that may have occurred.
catch (Exception e) {
e.printStackTrace();
}
finally {
if (rs != null)
try {
rs.close();
} catch (Exception e) {
}
if (stmt != null)
try {
stmt.close();
} catch (Exception e) {
}
if (con != null)
try {
con.close();
} catch (Exception e) {
}
}
}
}
SQL server中建立数据库建表录数据的代码:
CREATE DATAbase LibraryDB
ON PRIMARY (
NAME = 'LibraryDB',
FILENAME = 'F:SQL ServerMSSQL13.MSSQLSERVERMSSQLDATALibraryDB.mdf',
SIZE = 5MB,
FILEGROWTH = 1MB,
MAXSIZE = UNLIMITED
)
LOG ON (
NAME = 'LibraryDB_log',
FILENAME = 'F:SQL ServerMSSQL13.MSSQLSERVERMSSQLDATALibraryDB_log.lof',
SIZE = 3MB,
FILEGROWTH = 1MB,
MAXSIZE = 100MB
);
USE LibraryDB;
DROp TABLE IF EXISTS Student;
CREATE TABLE Student( Sno char(6),
Sname varchar(30) DEFAULT NULL,
Password char(6) DEFAULT '111111',
Credit int DEFAULT 100,
PRIMARY KEY(Sno));
INSERT INTO Student(Sno,Sname) VALUES ('000001','张三'),('000002','李四'),('000003','王五'),('000004','钱六');
INSERT INTO Student(Sno,Sname) VALUES ('000005','小明'),('000006','小红'),('000007','小刚'),('000008','小蓝');
SELECT * FROM Student;
