EasyXLS

利用jxl-2.6.12.jar快速解析excel文件，并支持在JavaBean中添加注解的方式读写文件（因jxl只支持excel2003以下版本，所以目前只限于xls格式的文件）

功能

1. 读取文件数据序列化为JavaBean
2. 反序列化JavaBean写入文件
3. 创建、读取、写入、删除excel
4. 可以在JavaBean上利用注解的方式标记属性，方便的读写excel

使用方法

  //创建并写入文件
  List<Employee> employees = new ArrayList<Employee>();
  employees.add(new Employee(1000, "Jones", 40, "Manager", 2975));
  employees.add(new Employee(1001, "Blake", 40, "Manager", 2850));
  employees.add(new Employee(1002, "Clark", 40, "Manager", 2450));
  employees.add(new Employee(1003, "Scott", 30, "Analyst", 3000));
  employees.add(new Employee(1004, "King", 50, "President", 5000));
  String[] titles = new String[] { "工号", "姓名", "年龄", "职称", "薪资" };
  String[] fieldNames = new String[] { "id", "name", "age", "job","salery" };

  try {
    XLSUtils xlsUtils = XLSUtils.getInstance(file);
    xlsUtils.writeExcel(Employee.class, employees, fieldNames, titles,"员工登记表"); //创建及写入excel
    xlsUtils.writeExcelByAnnotation(Employee.class, employees,	"员工登记表"); //注解方式写入excel
  } catch (Exception e) {
   e.printStackTrace();
  }  
  //读取文件
  String[] fieldNames = new String[] { "id", "name", "age", "job","salery" };
  List<Employee> employees = new ArrayList<Employee>();
  try {
   employees = xlsUtils.readExcel(Employee.class, fieldNames, 0,true); //按sheet编号读取excel
   employees = xlsUtils.readExcel(Employee.class, fieldNames,"员工登记表", true); //按sheet名称读取excel
   employees = xlsUtils.readExcelByAnnotation(Employee.class, 0,true); //注解方式读取excel
  } catch (Exception e) {
   e.printStackTrace();
  }
  //删除文件
  xlsUtils.deleteExcel(file);
  
  //带注解的bean
  public class Employee {
   //column 名称及在表格中的序号
   @ColumnTitle(columnTitle = "工号", columnIndex = 0)
   private long id;

   @ColumnTitle(columnTitle = "姓名", columnIndex = 1)
   private String name;

   @ColumnTitle(columnTitle = "年龄", columnIndex = 2)
   private int age;

   @ColumnTitle(columnTitle = "职位", columnIndex = 3)
   private String job;

   @ColumnTitle(columnTitle = "薪资", columnIndex = 4)
   private double salery;  
  }
