我有一个
Spring Boot 1.3.0(
Java 8)应用程序,需要使用Excel作为数据源. (由于Excel文件的类型,POI和JXL不起作用.)应用程序需要在unix环境中运行.我将应用程序配置为通过yml文件设置数据源url和driver-class-name.
是否有可以使用Excel作为数据源的驱动程序(最好在maven仓库中可用)？我应该为网址指定什么值？

最佳答案 对于Excel文件c：/temp/test1.xlsx和’Table’abc.您必须完全以此形式编写驱动程序名称！
对于Java8,您需要将所有sun包类从jre7复制到新的jar文件,再从项目文件夹中的jre7 bin文件夹复制JdbcOdbc.dll.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class JDBCExcelConnection {
public static void main(String[] args) {
Connection connection = null;
Statement statement = null;
ResultSet resultSet = null;
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
connection = DriverManager
.getConnection("jdbc:odbc:Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};DBQ=c:\\Temp\\test1.xlsx;readOnly=false");
statement = connection.createStatement();
resultSet = statement.executeQuery("SELECT * FROM [abc$]");
} catch (ClassNotFoundException e) {
System.err.println("ClassNotFoundException by driver load - " + e);
} catch (SQLException e) {
System.err.println("SQLException by connect - " + e);
} finally {
if (connection != null) {
try {
connection.close();
} catch (Exception e) {
}
}
if (statement != null) {
try {
statement.close();
} catch (Exception e) {
}
}
if (resultSet != null) {
try {
resultSet.close();
} catch (Exception e) {
}
}
}
}
}
