我的一贯风格，代码说明一切。。
废话不多说了，直接给大家贴代码了，具体代码如下所示：
package Tools;

import java.io.IOException;

import entity.Student;
public class ConvertXMSToSQL {
public static void main(String[] args) throws IllegalArgumentException,
IllegalAccessException {
// 得到表格中所有的数据
List listExcel = getAllByExcel("C:\Users\xxx\Desktop\zzz.xls");
try {
String path = "C:\Users\xxx\Desktop\convert.sql";// 文件保存路径、名字
File file = new File(path);
BufferedWriter ow = new BufferedWriter(new FileWriter(file));
for (Student c : listExcel) {
String sql = "insert into cfg_avatar values (" + outSql(c)
+ ")";
ow.write(sql + ";" + "n");
}// 写入内容
ow.close();
} catch (IOException e) {
e.printStackTrace();
}
}
public static List getAllByExcel(String file) {
List list = new ArrayList();
try {
Workbook rwb = Workbook.getWorkbook(new File(file));

int clos = rs.getColumns();// 得到所有的列

// 样例中，数据从第三列第一行开始
for (int i = 2; i < rows; i++) {
// 取得的每一行的所有数据存入listString

for (int j = 0; j < clos; j++) {

}

}
} catch (Exception e) {

}
return list;
}
public static Object newObject(Object obj, List list)
