左树右表的页面实际上也是对单独一张表进行增删改查,有点不同是,当点击左边的树节点时,需要查询表的数据,另外在增加时需要先选中树节点,然后增加的记录在这个节点类别下,比如类型为“计算机”,那么增加的一台电脑设备如thinkpad,就是属于这个“计算机”类别的,如下图所示:
同样省略前面的步骤
7、Service开发
/** * 产品,左树右表 * * @author xuqc * @date 2013-10-17 下午02:34:41 */ @Service public class T206Service extends AbsToftServiceImpl { private AggregatedValueObject billInfo; public AggregatedValueObject getBillInfo() { if(billInfo == null) { billInfo = new HYBillVO(); VOTableVO vo = new VOTableVO(); vo.setAttributeValue(VOTableVO.BILLVO, HYBillVO.class.getName()); vo.setAttributeValue(VOTableVO.HEADITEMVO, ProductDetailVO.class.getName()); vo.setAttributeValue(VOTableVO.PKFIELD, ProductDetailVO.PK_PRODUCT_DETAIL); billInfo.setParentVO(vo); } return billInfo; } }
8、Controller开发
/** * 左树右表 * * @author xuqc * @date 2013-10-17 下午02:55:09 */ @Controller @RequestMapping(value = "/busi/scene/t206") public class T206Controller extends AbsToftController { @Autowired private T206Service t206Service; @Override public T206Service getService() { return t206Service; } @Override public String getTreePkField() { return ProductDetailVO.PK_CATEGORY; } @RequestMapping(value = "/getItemTree.json") @ResponseBody public List<TreeVO> getTree() { String whereSql = " isnull(dr,0)=0 order by categorycode"; CategoryVO[] categorys = (CategoryVO[]) NWDao.getInstance().queryForSuperVOArrayByWhereClause(CategoryVO.class, whereSql); List<TreeVO> roots = new ArrayList<TreeVO>(); if(categorys == null || categorys.length == 0) { return roots; } HashMap<String, List<TreeVO>> allLeafs = new HashMap<String, List<TreeVO>>(); // 对子节点进行分组 for(CategoryVO category : categorys) { TreeVO vo = new TreeVO(); vo.setId(category.getPk_category()); vo.setCode(category.getCategorycode()); vo.setText(category.getCategorycode() + " " + category.getCategoryname());// 编码+名称显示 if(StringUtils.isBlank(category.getPk_parentclass())) { vo.setLeaf(false); roots.add(vo); continue; } if(allLeafs.get(category.getPk_parentclass()) == null) { ArrayList<TreeVO> list = new ArrayList<TreeVO>(); list.add(vo); allLeafs.put(category.getPk_parentclass(), list); } else { allLeafs.get(category.getPk_parentclass()).add(vo); } } return getTrunk(allLeafs, roots); } private List<TreeVO> getTrunk(HashMap<String, List<TreeVO>> leafs, List<TreeVO> trunks) { for(TreeVO trunk : trunks) { if(leafs.get(trunk.getId()) == null || leafs.get(trunk.getId()).size() == 0) { trunk.setLeaf(true); continue; } trunk.setChildren(getTrunk(leafs, leafs.get(trunk.getId()))); } return trunks; } }
9、对应的jsp文件
