结构不多说，bean的封装很简单，直接上核心代码吧，自己根据需要把不要的属性自己过滤掉：
public List<MenuBo> getMenuByUserId(Long user_id,Long company_id) {
//获取所有的菜单
List<MenuBo> rootMenu = new ArrayList<>();
rootMenu = companyFuncInfoMapper.getMenuByUserId(user_id);
List<Long> func_list = companyFuncInfoMapper.getFuncCompanyIdShipByCompanyId(company_id);
Iterator<MenuBo> it=rootMenu.iterator();
while(it.hasNext()){
MenuBo menuBoIt=it.next();
if(!func_list.contains(menuBoIt.getId())){
it.remove();
}
}
//最后的结果
List<MenuBo> menuList = new ArrayList<>();
// 先找到所有的一级菜单
for (int i = 0; i < rootMenu .size(); i++) {
// 一级菜单没有parentId
if (rootMenu .get(i).getPid()==0L) {
// 一级菜单没有parentId
menuList.add(rootMenu.get(i));
}
}
// 为一级菜单设置子菜单，getChild是递归调用的
for (MenuBo menu : menuList) {
Meta meta = new Meta();
meta.setBreadName(menu.getBreadName());
meta.setBreadIcon(menu.getBreadIcon());
meta.setTitle(menu.getBreadName());
menu.setComponent(menu.getComponent());
menu.setMeta(meta);
menu.setChildren(getChild(menu.getId(), rootMenu));
}
return menuList;
}
获取子菜单的方法：
private static List<MenuBo> getChild(Long id, List<MenuBo> rootMenu) {
// 子菜单
List<MenuBo> childList = new ArrayList<>();
for (MenuBo menu : rootMenu) {
// 遍历所有节点，将父菜单id与传过来的id比较
if (menu.getPid()!=null) {
if (menu.getPid().intValue()==id.intValue()) {
Meta meta = new Meta();
meta.setBreadName(menu.getBreadName());
meta.setBreadIcon(menu.getBreadIcon());
meta.setTitle(menu.getBreadName());
menu.setMeta(meta);
menu.setComponent(menu.getComponent());
menu.setTitle(menu.getBreadName());
childList.add(menu);
}
}
}
// 把子菜单的子菜单再循环一遍
for (MenuBo children : childList) {// 没有url子菜单还有子菜单
if (StringUtils.isBlank(children.getPath())) {
// 递归
children.setChildren(getChild(children.getId(), rootMenu));
}
} // 递归退出条件
if (childList.size() == 0) {
return null;
}
return childList;
}
最终结果：

大家看json结构自己写一下实体类就行了。
