Question

我尝试连接数据库只是尝试UcanAccess，就像我在这里找到的一个例子，但它不起作用，它有一个BIG_INT错误，我不知道如何解决它;我在java8上工作，我添加了commons-lag 2.6，commons-logging 1.1.1，hsqldb 2.1.4，jackaccess 2.1.6和ucanaccess 4.0.4，我在win10上工作代码：

<input type="text" class="input-sm "  uib-datepicker-popup="{{format}}"
       ng-model="requestDate" is-open="datepicker.opened1"    <--
       datepicker-options="dateOptions"  close-text="Close"  />
<span class=" input-sm" >
    <button type="button" class="btn btn-default"  ng-click="openCalendar($even, 'opened1')">   <--
      <i class="glyphicon glyphicon-calendar"></i>
    </button>
</span>

这些是错误：

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class MsAccessDatabaseConnectionInJava8 {

    public static void main(String[] args) {

        // variables
        Connection connection = null;
        Statement statement = null;
        ResultSet resultSet = null;

        // Step 1: Loading or registering Oracle JDBC driver class
        /*try {

            Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
        }
        catch(ClassNotFoundException cnfex) {

            System.out.println("Problem in loading or "
                    + "registering MS Access JDBC driver");
            cnfex.printStackTrace();
        }*/

        // Step 2: Opening database connection
        try {

            String msAccDB = "C:/Users/utente/Documents/Prova.accdb";
            String dbURL = "jdbc:ucanaccess://" +msAccDB; 

            // Step 2.A: Create and get connection using DriverManager class
            connection = DriverManager.getConnection(dbURL); 

            // Step 2.B: Creating JDBC Statement 
            statement = connection.createStatement();

            // Step 2.C: Executing SQL &amp; retrieve data into ResultSet
            resultSet = statement.executeQuery("SELECT * FROM PLAYER");

            System.out.println("ID\tName\t\t\tAge\tMatches");
            System.out.println("==\t================\t===\t=======");

            // processing returned data and printing into console
            while(resultSet.next()) {
                System.out.println(resultSet);
            }
        }
        catch(SQLException sqlex){
            sqlex.printStackTrace();
        }
        finally {

            // Step 3: Closing database connection
            try {
                if(null != connection) {

                    // cleanup resources, once after processing
                    resultSet.close();
                    statement.close();

                    // and then finally close connection
                    connection.close();
                }
            }
            catch (SQLException sqlex) {
                sqlex.printStackTrace();
            }
        }
    }
}

您没有使用UCanAccess 4.0.4的正确依赖项。他们是：

公地琅-2.6
共享记录-1.1.3
HSQLDB 2.3.1
jackcess-2.1.11

UcanAccess和Java出现BIG_INT错误
