springboot+shiro+thymeleaf页面级元素的权限控制
我用的springboot2.1版本。
学习了很多大神的总结,基本上都是一样的,shiro权限框架,前端验证是为jsp设计的,其中的tag只能用于jsp系列的模板引擎。
使用了thymeleaf作为前端模板引擎,使用HTML文件,没法引入shiro的tag lib,此时如果要使用shiro的话,可以引入 thymeleaf-extras-shiro.jar这个拓展包来曲线实现shiro的前端验证。
在pom.xml中加入如下依赖:
<dependency>
<groupId>com.github.theborakompanioni</groupId>
<artifactId>thymeleaf-extras-shiro</artifactId>
<version>1.2.1</version>
</dependency>
然后在配置shiro的configuration时,加入
@Bean
public ShiroDialect shiroDialect() {
return new ShiroDialect();
}
然后在需要控制的页面元素的页面头上加上xmlns:
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org"
xmlns:shiro="http://www.pollix.at/thymeleaf/shiro">
<head>
<meta charset="UTF-8">
<title>Add</title>
</head>
<body>
<h3>用户添加界面</h3>
<p shiro:hasRole="admin"> 有权限</p>
<p shiro:hasRole="test">无权限</p>
</body>
</html>
其他的配置,和shiro用于后台权限控制的配置一样,然后就可以了,事实上我也是这样做的,但是遇到一个问题,
一直报这个异常

这个异常是说找不到AbstractTextChildModifierAttrProcessor这个类,事实上是这个类是有的,只是在编译的时候能找到,所以没有异常,在运行的时候找不到这个类,所以就异常了,仔细检查了好多遍,最后我改了springboot的版本,然后就不报错了,开始我使用的是最新2.0版本,改到1.5就正常了
下面贴一下关于shiro用到的包
希望遇到同样问题的同学绕过个坑
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.4.0</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.2.5</version>
</dependency>
<dependency>

<artifactId>thymeleaf-extras-shiro</artifactId>
<version>1.2.1</version>
</dependency>
shiro整合thymeleaf常见权限控制标签使用
1、未认证并且未记住的用户
<!-- 当前用户是否为“游客”,如果是未认证,也未记住的用户,那么就显示该 p 标签中的内容 -->
<p shiro:guest="">Please <a href="login.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" >login</a></p>
2、未认证,已记住的用户
<!-- 未认证的用户但已记住,与下面的 authenticated 标签相对应。
与 guest 标签的区别是,该标签包含已记住用户。 -->
<p shiro:notAuthenticated="">
Please <a href="login.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" >login</a> in order to update your credit card information.
</p>
3、认证通过或已记住的用户
<!-- 认证通过或已记住的用户,则显示该 p 标签中的内容 -->
<p shiro:user="">
Welcome back John! Not John? Click <a href="login.html" rel="external nofollow" rel="external nofollow" rel="external nofollow" >here</a> to login.
</p>
4、认证通过,未记住的用户
<!-- 已认证通过,但未记住的用户。这是与 user 标签的区别所在。 -->
<p shiro:authenticated="">
Hello, <span shiro:principal=""></span>, how are you today?
</p>
<a shiro:authenticated="" href="updateAccount.html" rel="external nofollow" >Update your contact information</a>
5、当前用户信息
<!-- 输出当前用户信息,通常为登录帐号信息 -->
<p>Hello, <shiro:principal />, how are you today?</p>
6、验证当前用户是否具有该角色
<!-- 验证当前用户是否具有该 admin 角色,若拥有,则显示 a 标签的内容 -->
<a shiro:hasRole="admin" href="admin.html" rel="external nofollow" >Administer the system</a>
7、验证当前用户是否不具有该角色
<!-- 与 hasRole 标签逻辑相反,当用户不属于该 developer 角色时显示 -->
<p shiro:lacksRole="developer">
Sorry, you are not allowed to developer the system.
</p>
8、验证当前用户是否同时具有以下所有角色
<!-- 验证当前用户是否同时具有以下所有角色 -->
<p shiro:hasAllRoles="developer, product">
You are a developer and a admin.
</p>
9、验证当前用户是否具于以下任意一个角色
<!-- 验证当前用户是否具于以下任意一个角色 -->
<p shiro:hasAnyRoles="admin, vip, developer">
You are a admin, vip, or developer.
</p>
10、验证当前用户是否拥有指定权限
<!-- 验证当前用户是否拥有 update 权限 -->
<a shiro:hasPermission="update" href="createUser.html" rel="external nofollow" >添加用户</a>
11、验证当前用户是否不拥有指定权限
<!-- 与 hasPermission 标签逻辑相反,当前用户不拥有指定权限 delete -->
<p shiro:lacksPermission="delete">
Sorry, you are not allowed to delete user accounts.
</p>
12、验证当前用户是否同时拥有以下所有角色
<!-- 验证当前用户是否同时拥有以下所有角色 -->
<p shiro:hasAllPermissions="add, update">
You can see or add users.
</p>
13、验证当前用户是否拥有以下任意一个权限
<!-- 验证当前用户是否拥有以下任意一个权限 -->
<p shiro:hasAnyPermissions="add, update, delete">
You can see or delete users.
</p>
以上为个人经验,希望能给大家一个参考,也希望大家多多支持编程网。
