一、权限配置
1. 思路
- 初始化所有权限，显示页面
- 共三级，若上级id为0并且下级权限数组长度为0，添加增删改查菜单
- 若存在上级并且下级权限数组长度为0，添加增删改查菜单
2. 代码

二、权限配置好之后，页面加载
1. 思路
- 前台获取列表页面时，controller中获取权限列表，将数据写入model中前台获取列表页面时，controller中获取权限列表，将数据写入model中
- 前台jsp页面加载时判断是否有权限，若有权限显示，无权限，不显示
2. 代码
controller
/**
* 卡清单列表
* @param
* @param model
* @return
*/
@RequestMapping("cardList")
public String cardList(ToyCardVo toyCardVo, Model model){
SysDictionaryVo sysDictionaryVo = new SysDictionaryVo();
sysDictionaryVo.setName("提货卡类型");
List<SysDictionaryVo> typeList = sysDictionaryService.findByNameGetList(sysDictionaryVo);
model.addAttribute("typeList",typeList);
//菜单权限
model.addAttribute("auth", getAuthority(45L));//
return "/toy/card/cardList";
}
/**
* 获得当前用户菜单权限
* @param menuid 菜单id
* @return long
*/
public SysAuthorityVo getAuthority(Long menuid){
Long roleId=(Long)(getRequest().getSession().getAttribute("roleId"));
SysAuthorityVo sysAuthorityVo = new SysAuthorityVo();
sysAuthorityVo.setRoleId(roleId);
sysAuthorityVo.setMenuId(menuid);
sysAuthorityVo=sysAuthorityService.findById(sysAuthorityVo);
return sysAuthorityVo;
}
实体类
public class SysAuthority implements java.io.Serializable {
// Fields
private Long id;
private Long roleId;
private Long menuId;
private Short isadd;
private Short isupdate;
private Short isdelete;
private Short isquery;
Vo类
@Alias("SysAuthority")
public class SysAuthorityVo extends SysAuthority {
private String menuIds;
列表展现jsp方式一
var isdelete=${auth.isdelete};
if(isupdate==1){
if(data.isact==1 || data.isact==2){
html+= "<a class='green' href='/manage/card/toCardAdd?id="+data.id+"'>"+
"编辑"+
"</a>"
}
}
列表展现jsp方式二
<c:if test="${auth.isadd == 1}">
<button class="btn btn-success icon-plus" id="add"> 新增 </button>
</c:if>
