  public String edit(){

     Integer id =Integer.parseInt(org.apache.struts2.ServletActionContext.getRequest().getParameter("id"));

  department = departmentService.findById(id);

  return "editSuccess";

  }

  把获取id值得方法修改一下

  试试能不能解决问题，注意粗体字

  //驱动模型

  private Department department ;

  @Override

  public Department getModel() {

  return department;

  }

  改为：

  private Department department = new Department() ;

  @Override

  public Department getModel() {

  return department;

  }

  有可能是department没有正常接收到页面传来的数据吧！
