樹形數據的遞歸

對於 樹形 數據的遞歸

1. 在model中添加 屬性   須要添加 Department 屬性，List<Department>

public class Department {

	private String NAME;			//名稱
	private String NAME_EN;			//英文名稱
	private String BIANMA;			//編碼
	private String PARENT_ID;		//上級ID
	private String HEADMAN;			//負責人
	private String TEL;				//電話
	private String FUNCTIONS;		//部門職能
	private String BZ;				//備註
	private	String ADDRESS;			//地址
	private String DEPARTMENT_ID;	//主鍵
	private String target;
	private Department department;
	private List<Department> subDepartment;
	private boolean hasDepartment = false;
	private String treeurl;
	private String icon;
}

2. 

/**
	 * 獲取全部數據並填充每條數據的子級列表(遞歸處理)
	 * @param MENU_ID
	 * @return
	 * @throws Exception
	 */
	public List<Department> listAllDepartment(String parentId) throws Exception {
		List<Department> departmentList = this.listSubDepartmentByParentId(parentId);
		for(Department depar : departmentList){
            //設置頁面顯示屬性
			depar.setTreeurl("department/list.do?DEPARTMENT_ID="+depar.getDEPARTMENT_ID());
            //設置子屬性
			depar.setSubDepartment(this.listAllDepartment(depar.getDEPARTMENT_ID()));
			depar.setTarget("treeFrame");
			depar.setIcon("static/images/user.gif");
		}
		return departmentList;
	}
