使用ztree展示树形菜单结构

@RequestMapping("/edit")

public String edit(Integer roleId, Model model) {

……

//树形菜单资源

List<Map<String, Object>> allResources = resourceService.getTreeMap();

//当前角色已有资源，设置checked和open属性

if (roleId != null) {

Set<CmsResource> roleResources = resourceService.findByRoleId(roleId);

if (roleResources != null && !roleResources.isEmpty()) {

for (Map<String, Object> resource : allResources) {

Integer id =(Integer)resource.get("id");

for (CmsResource roleResource : roleResources) {

if (roleResource.getResourceId().equals(id)) {

resource.put("checked", true);

resource.put("open", true);

break;

}

}

}

}

}

//转换为json字符串

String resourceJson = new Gson().toJson(allResources);

model.addAttribute("resourceJson", resourceJson);

return "/role/edit";

}
