SQL Server JDBC 連接:sqljdbc4.jar sqljdbc_auth.dll配置與windows方式登錄

• 下載對應版本的JDBC Driver，解壓並安裝
• 使用 System.out.println(System.getProperty("java.library.path")); 查看java.library.path:                                                將sqljdbc_auth.dll複製到其中一個目錄

代碼如下：

需要特別注意Windows身份驗證的連接URL寫法，官方文檔上有
//Use the JDBC driver  
import java.sql.*;  
import com.microsoft.sqlserver.jdbc.SQLServerDriver;

    public class Test {  

        // Connect to your database.  
        // Replace server name, user name, and password with your credentials  
        public static void main(String[] args) {  
            String connectionString = "jdbc:sqlserver://localhost;" +         
              "integratedSecurity=true;" + "databaseName=test;"; 

            // Declare the JDBC objects.  
            Connection connection = null;  
            Statement statement = null;   
            ResultSet resultSet = null;

                connection = DriverManager.getConnection(connectionString);

                String selectSql = "SELECT sname from student";  
                statement = connection.createStatement();  
                resultSet = statement.executeQuery(selectSql);  

                // Print results from select statement  
                while (resultSet.next())   
                {  
                    System.out.println(resultSet.getString(1));  
                }  

            }  
            catch (Exception e) {  
                e.printStackTrace();  
            }  
            finally {  
                if (connection != null) try { connection.close(); } catch(Exception e) {} 
                if (statement != null) try { statement.close(); } catch(Exception e) {}  
                if (connection != null) try { connection.close(); } catch(Exception e) {}   
            }  
        }
