public class Department implements java.io.Serializable {
        private Integer departmentId;
private String departmentName;
private String departmentComment;

...ExtJS表单提交后,从firebug post参数是：
departmentID 39
departmentName 组织部
departmentEmployeeId 2
departmentPhone 12345678
departmentComment 这是组织部Actioin类:获取得的数据是：System.out.println打印：
System.out.println(department.getDepartmentId()+","+department.getDepartmentName()+","+
department.getDepartmentEmployeeId()+","+department.getDepartmentPhone()+","+
department.getDepartmentComment());打印结果是：
