1、实体类中添加子菜单列表或集合
@TableField(exist = false)
private Set<SysMenu> childrenList = new HashSet<>();
2、定义一个方法递归的获取子菜单
public SysMenu getChildrenList(SysMenu sysMenu, List<SysMenu> sysMenuList) {
for (SysMenu menu : sysMenuList) {
if (menu.getMenuParentId().equals(sysMenu.getId())) {
sysMenu.getChildrenList().add(getChildrenList(menu, sysMenuList));
}
}
return sysMenu;
}
3、构建菜单树
public List<SysMenu> menuTree() {
//获取所有菜单
List<SysMenu> sysMenuList = list(new LambdaQueryWrapper<SysMenu>()
//::在java8中的作用就是获得方法
.eq(SysMenu::getMenuType, ResultConstant.MENU)
);
//stream().filter()作用：过滤一个List对象，查找符合条件的对象集合
List<SysMenu> firstMenuList = sysMenuList.stream().filter
//过滤出一级菜单
(s -> s.getMenuParentId().equals(ResultConstant.MENU_TOP))
// 返回list集合形式
.collect(Collectors.toList());
// 遍历一级菜单,构造菜单树
for (SysMenu menu : firstMenuList) {
getChildrenList(menu, sysMenuList);
}
return firstMenuList;
}
菜单表如下
CREATE TABLE `sys_menu` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`menu_name` varchar(255) COLLATE utf8mb4_bin DEFAULT NULL COMMENT '资源名称',
`menu_permission` varchar(255) COLLATE utf8mb4_bin DEFAULT NULL COMMENT '权限',
