阅读更多

  相信很多人都在为无法默认选中树节点而苦恼，弄出来了特意分享出来

 public Object Menu(String roleId, HttpServletRequest req) {
        List list = menuService.query(Cnd.orderBy().asc("location").asc("path"));
        List datas = roleService.getDatas();
        List menus = new ArrayList<>();
        List roleMenus = roleService.getMenusAndButtons(roleId);//当前角色的权限
        for (SysMenu menu : list) {
            NutMap map = new NutMap();
            for (SysMenu bt : datas) {
                if (menu.getPath().equals(bt.getPath().substring(0, bt.getPath().length() - 4))) {
                    menu.setHasChildren(true);
                    break;
                }
            }
            for(SysMenu rm:roleMenus){
                if (menu.getId().equals(rm.getId())){
                    map.put("state", new State(false,false,true));//是否允许编辑-是否展开-是否选中树节点
                    break;
                }
            }
            map.put("id", menu.getId());
            map.put("text", menu.getName());
            map.put("icon", Strings.sBlank(menu.getIcon()));
            map.put("parent", "".equals(Strings.sNull(menu.getParentId())) ? "#" : menu.getParentId());
            map.put("data", menu.getHref());
            menus.add(map);
        }
        req.setAttribute("menus", Json.toJson(menus));
        return Strings.isBlank(roleId) ? null : roleService.fetch(roleId);
    }

 

public class State {
    private boolean disabled;
    private boolean opened;
    private boolean selected;

    /**
     * 树节点勾选
     * @param disabled  编辑
     * @param opened  是否展开

     */
    public State(boolean disabled,boolean opened,boolean selected){
        this.disabled=disabled;
        this.opened=opened;
        this.selected=selected;

    }

    public boolean isDisabled() {
        return disabled;
    }

    public void setDisabled(boolean disabled) {
        this.disabled = disabled;
    }

    public boolean isOpened() {
        return opened;
    }

    public void setOpened(boolean opened) {
        this.opened = opened;
    }

    public boolean isSelected() {
        return selected;
    }

    public void setSelected(boolean selected) {
