1、從儲存系統中獲取用於對應的許可權儲存到session中

session.setAttribute("authority", roleService.strAuthority(user.getRoleId()));

2、前端判斷是否應該擁有該許可權

<c:if test="${fn:contains(sessionScope.authority,30101)}">
	<span class="l">
		<a href="#" class="btn btn-primary radius">
			<i class="Hui-iconfont"></i> 新增介面
		</a>
	</span> 
</c:if>
