整合shiro环境

先搭建好一个简单的boot项目这里不做说明了
导入shiro依赖

        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.7.1</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring-boot-web</artifactId>
        </dependency>

简单例子

编写自定义UserRealm类

package com.jie.config;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
//自定义UserRealm类需要继承该类
public class UserRealm extends AuthorizingRealm {
    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了授权方法");
        return null;
    }
    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("执行了认证方法");
        return null;
    }
}

编写shiro配置类(代码都是套路T-T)

package com.jie.config;


import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ShiroConfig {
    @Bean
    //如果我们在某个注入点需要另一个 bean，我们需要专门指出它。我们可以通过 @Qualifier 注解来做到这一点。
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean bean=new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);
        return bean;
    }
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager=new DefaultWebSecurityManager();
        //关联realm对象
        securityManager.setRealm(userRealm);
        return securityManager;
    }
    //创建realm对象 需要自定义类
    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }
}

编写一个主界面可以跳到测试用的add,update页面
用于后续权限测试管理

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<a th:href="@{/user/add}">add</a> | <a th:href="@{/user/update}">update</a>
</body>
</html>
