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.BufferedWriter;import java.io.File;import java.io.FileWriter;import java.io.IOException;import java.lang.reflect.Field;import java.util.ArrayList;import java.util.List;import jxl.Sheet;import jxl.Workbook;import entity.Student;public class ConvertXMSToSQL {/*** 从xls表格中获取数据，生成可执行的sql文件，用以插入数据库，注意需要引入jxl包！支持int,Integer,long,Long,String* ,可自行扩展* * @param args* @throws IllegalArgumentException* @throws IllegalAccessException*/public static void main(String[] args) throws IllegalArgumentException,IllegalAccessException {// 得到表格中所有的数据List<Student> 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();}}/*** 从xls中获取数据* * @param file* @return*/public static List<Student> getAllByExcel(String file) {List<Student> list = new ArrayList<Student>();try {Workbook rwb = Workbook.getWorkbook(new File(file));Sheet rs = rwb.getSheet(0);int clos = rs.getColumns();// 得到所有的列int rows = rs.getRows();// 得到所有的行// 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listStringList<String> listString = new ArrayList<String>();for (int j = 0; j < clos; j++) {String str = rs.getCell(j, i).getContents();listString.add(str);}Student Student = (Student) newObject(new Student(), listString);list.add(Student);}} catch (Exception e) {e.printStackTrace();}return list;}/*** 使用反射设置数据。此例中可设置的数据类型有限，没有的请自己添加！！！* * @param obj* @param list* @return* @throws IllegalArgumentException* @throws IllegalAccessException*/public static Object newObject(Object obj, List<String> list)throws IllegalArgumentException, IllegalAccessException {Field[] field = obj.getClass().getDeclaredFields();for (int i = 0; i < field.length; i++) {Field f = field[i];f.setAccessible(true);if (f.getType() == String.class) {f.set(obj, list.get(i));}if (f.getType() == Integer.class) {f.set(obj, Integer.parseInt(list.get(i)));}if (f.getType() == int.class) {f.set(obj, Integer.parseInt(list.get(i)));}if (f.getType() == Long.class) {f.set(obj, Long.parseLong(list.get(i)));}if (f.getType() == long.class) {f.set(obj, Long.parseLong(list.get(i)));}}return obj;}/*** * @param obj* @return* @throws IllegalArgumentException* @throws IllegalAccessException*/public static String outSql(Object obj) throws IllegalArgumentException,IllegalAccessException {StringBuffer buffer = new StringBuffer();Field[] field = obj.getClass().getDeclaredFields();for (int i = 0; i < field.length; i++) {Field f = field[i];f.setAccessible(true);if (f.getType() == String.class) {buffer.append("'");}buffer.append(f.get(obj));if (f.getType() == String.class) {buffer.append("'");}if (i < field.length - 1) {buffer.append(",");}}return buffer.toString();}}
