shiro权限项目中的简单应用

Posted 2022-11-24 @路痴

SpringMVC+maven

项目需要使用shiro，所以自学了几天，仅提供给新手，请根据文档查看…该项目仅是测试项目，并不完善，只实现了需要使用的基本功能，并且只提供了使用shiro模块的代码。楼主新人第一次写，如有问题希望能提出来，由衷的感谢。

首先是pom.xml：

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-core</artifactId>
    <version>1.2.0</version>
</dependency>
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-web</artifactId>
    <version>1.2.0</version>
</dependency>
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.2.0</version>
</dependency>
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-ehcache</artifactId>
    <version>1.2.0</version>
</dependency>

以下是web.xml配置：

<filter>
    <!-- filter-name需要和shiro的过滤器id一致 -->
    <filter-name>shiroFilter</filter-name>
    <filter-class>
        org.springframework.web.filter.DelegatingFilterProxy
    </filter-class>
    <init-param>
        <param-name>targetFilterLifecycle</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>shiroFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

以下是shiro的配置：

使用shiro的标签需要引用：

<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>

以下是按照登录时保存的权限显示按钮

<div class="tools">
    <ul class="toolbar">
        <shiro:hasPermission name="add">
