树形数据的递归

对于 树形 数据的递归

1. 在model中添加 属性   须要添加 Department 属性，List<Department>

public class Department {

	private String NAME;			//名称
	private String NAME_EN;			//英文名称
	private String BIANMA;			//编码
	private String PARENT_ID;		//上级ID
	private String HEADMAN;			//负责人
	private String TEL;				//电话
	private String FUNCTIONS;		//部门职能
	private String BZ;				//备注
	private	String ADDRESS;			//地址
	private String DEPARTMENT_ID;	//主键
	private String target;
	private Department department;
	private List<Department> subDepartment;
	private boolean hasDepartment = false;
	private String treeurl;
	private String icon;
}

2. 

/**
	 * 获取全部数据并填充每条数据的子级列表(递归处理)
	 * @param MENU_ID
	 * @return
	 * @throws Exception
	 */
	public List<Department> listAllDepartment(String parentId) throws Exception {
		List<Department> departmentList = this.listSubDepartmentByParentId(parentId);
		for(Department depar : departmentList){
            //设置页面显示属性
			depar.setTreeurl("department/list.do?DEPARTMENT_ID="+depar.getDEPARTMENT_ID());
            //设置子属性
			depar.setSubDepartment(this.listAllDepartment(depar.getDEPARTMENT_ID()));
			depar.setTarget("treeFrame");
			depar.setIcon("static/images/user.gif");
		}
		return departmentList;
	}
