我已执行以下步骤: 1-控制面板>管理工具>单击ODBC
2-转到用户DSN并单击添加按钮
3-选择相应的数据库(SQL Server Native Client)
4-将名称命名为DSN并保存
通过pom.xml将以下JDBC驱动程序添加到我的项目中:
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>6.5.2.jre9-preview</version>
<scope>test</scope>
</dependency>
&#13;
然后我从eclipse执行了以下简单代码:
的Class.forName(&#34; com.microsoft.sqlserver.jdbc.SQLServerDriver&#34);
连接conn = DriverManager.getConnection(&#34; wsyddbd10678,1433&#34;,&#34;用户名&#34;,&#34;密码&#34;);
Statement st = conn.createStatement();
String Sql =&#34;从miris.dimset中选择*其中setsk介于5499和5510之间&#34 ;;
ResultSet rs = st.executeQuery(Sql);
while(rs.next())
{ 的System.out.println(rs.getString(&#34; setsk&#34));
}
但它给我一个错误说:
Exception in thread "main" java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver.
请建议..

获取与DB的连接您需要首先设置一些依赖项,具体取决于您连接的内容(哪个DB)。
对于MSSQL:
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>6.1.0.jre8</version>
</dependency>
以下是几种可以连接到DB的方法:
最简单(直接连接)
private WebDriver driver;
private Connection con = null;
private Statement stmt = null;
String dataBaseName = "testDB";
String dbDriver = "jdbc:sqlserver://localhost:3306/";
String user = "user";
String pass = "pass";
String Query;
ResultSet res;
public void DBConnection() throws Exception {
try {
Class.forName(
"com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection con = DriverManager.getConnection(
dbDriver + dataBaseName, user, pass);
stmt = con.createStatement();
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
@Test
public void testDB() throws Exception {
try {
Query = "Select * from table";
res = stmt.executeQuery(Query);
driver = new FirefoxDriver(); //or whatever driver
driver.get("//some URL //");
while (res.next()) //move to the next row in result set,
//... do your stuff //
}
} catch(Exception e)
{
System.out.println(e.getMessage());
}
或您的示例(已更新);
连接语法(MS-SQL Server):
[URL] = jdbc:sqlserver:// [ipAddress]:portNumber / dbName
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection con = DriverManager.getConnection([URL], userName, password);
或试试这个:
Class.forName("net.sourceforge.jtds.jdbc.Driver");
Connection con = DriverManager.getConnection([URL],userName, password);
然后是代码的其余部分:
Statement st = conn.createStatement();
String Sql = "query";
ResultSet rs = st.executeQuery(Sql);
while (rs.next())
{
System.out.println(rs.getString("setsk"));
}
(或者我认为最好的)Hibernate
设置它几乎没有什么工作,但是当它启动并运行时,它确实令人满意。以下是关于它的教程:https://www.javatpoint.com/steps-to-create-first-hibernate-application
希望这有用。
