JAVA代码

if(StringUtil.isNotNull(businessId)){List<AppProjPropLink> linkList = projTypeService.getCusPropByProjTypeId(businessId, metaCode);Map<String, List<AppProjPropLink>> map = new HashMap<String, List<AppProjPropLink>>();for (AppProjPropLink appProjPropLink : linkList) {if(!StringUtil.isNotNull(appProjPropLink.getMetaProp().getDictSelfGroup())){if(!StringUtil.isNotNull(map.get("未分组"))){List<AppProjPropLink> tempList = new ArrayList<AppProjPropLink>();tempList.add(appProjPropLink);map.put("未分组", tempList);}else{List<AppProjPropLink> tempList = map.get("未分组");tempList.add(appProjPropLink);map.put("未分组", tempList);}}else{if(!StringUtil.isNotNull(map.get(appProjPropLink.getMetaProp().getDictSelfGroup().getName()))){List<AppProjPropLink> tempList = new ArrayList<AppProjPropLink>();tempList.add(appProjPropLink);map.put(appProjPropLink.getMetaProp().getDictSelfGroup().getName(), tempList);}else{List<AppProjPropLink> tempList = map.get(appProjPropLink.getMetaProp().getDictSelfGroup().getName());tempList.add(appProjPropLink);map.put(appProjPropLink.getMetaProp().getDictSelfGroup().getName(), tempList);}}}model.addAttribute("map", map);}
