找不到 jdbc:ucanaccess://C:\Users\Asim Iqbal\Documents\PersonInfo.accdb 的合适驱动程序

Question

我不得不面对这个错误：

No suitable driver found for jdbc:ucanaccess://C:\Users\Asim Iqbal\Documents\PersonInfo.accdb org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:555)

在我的 JSP 项目中。但是当我分别运行PersonDAO.java的时候，就正常了。但是，通过使用 Bean，我不得不面对这种类型的错误。这些文件如下。

PersonDAO.java

import java.util.*;

import java.sql.*;

import java.io.*;
public class PersonDAO implements Serializable  {
private PreparedStatement stmt;

public ArrayList pList;
String url="jdbc:ucanaccess://C:\Users\Asim Iqbal\Documents\PersonInfo.accdb";

Connection   conn = DriverManager.getConnection(url);

public PersonDAO() throws SQLException{

    establishConnection();
}
private void establishConnection() throws SQLException
{
    String url1="jdbc:ucanaccess://C:\Users\Asim Iqbal\Documents\PersonInfo.accdb";
    conn = DriverManager.getConnection(url1);
}

public ArrayList getPerson(String name) throws SQLException { 
    PersonInfo pInfo=new PersonInfo();

    pList=new ArrayList();

    String sql="SELECT * FROM Person WHERE name=?";

    stmt=conn.prepareStatement(sql);

    stmt.setString(1,name);

    ResultSet rs=stmt.executeQuery();
     String add,n;

     String p;

    while(rs.next()){

        n=rs.getString("Name");
        add=rs.getString("Address");

        p=rs.getString("PhoneNumber");

        pInfo.setName(n);

        pInfo.setAddress(add);

        pInfo.setpNumber(p);

        pList.add(pInfo);
    }
    return pList;

    }
 }

saveperson.jsp

</head>
    <jsp:useBean id="pDAO" class="Person.PersonDAO" scope = "request" /> 

    <jsp:useBean id="personBean" class="Person.PersonInfo" scope="request"/> 

    <jsp:setProperty name="personBean" property="name" param="name"/>

    <jsp:setProperty name="personBean" property="address" param="address"/>

    <jsp:setProperty name="personBean" property="pNumber" param="pNumber"/>
    <%
     pDAO.setPerson(personBean);
    %>
    <center>

    <h1>You have successfully add the record!</h1>
    <h4>  
          <a href="index.html" > Add another Person Record </a> <br>
          <br><br>
          <a href="searchperson.jsp" > Search Person </a>    
      </h4> 
    </center>

请告诉我哪里做错了..

您必须将 ucanaccess jar 添加到类路径并调用 Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");，然后再尝试打开连接（一次就足够），以便 DriverManager 找到具有该 url 的驱动程序，请参阅 here.
