核心业务:点击系统首页中的菜单管理, 在对应的一个div中异步加载菜单页面.
- 业务描述
- 定义controller对象处理客户端菜单访问请求
- 定义相关方法处理列表页面加载需求
- 业务实现
创建一个SysMenuController类,基于Controller类定义页面响应方法
- 代码实现

@Controller
@RequestMapping("/menu/")
public class SysMenuController {
@RequestMapping("doMenuListUI")
public String doMenuListUI() {
return "sys/menu_list";
}
}在WEB-INF/pages/sys目录下定义menu_list.html页面.
- 业务描述

核心业务
- 查询此菜单有没有对应的子菜单,有则不允许删除
- 删除菜单(市场有两种业务)
- 有角色菜单关系数据,则不允许删除
- 有角色菜单关系数据,将关系数据一起删除.(本次策略)
- 业务实现
SysMenuDao
- 基于菜单id查询是否有子菜单(有子菜单则不能删除)
/**
* 根据菜单id统计子菜单的个数
* @param id 菜单id
* @return 子菜单个数
*/
int getChildCount(Integer id);- 根据菜单id删除菜单自身信息.
/**
* 根据菜单id删除菜单
* @param id
* @return
*/
int deleteObject(Integer id);SysRoleMenuDao
- 根据菜单id删除角色菜单关系数据
public interface SysRoleMenuDao {
/**
* 根据删除的菜单id删除关联的角色信息
* @param menuId
* @return
*/
int deleteObjectsByMenuId(@Param("menuId") Integer menuId);
