Shrio与Spring Security

Shrio是什么

官网的介绍：是一个Java安全框架，可执行身份验证授权、加密和会话管理，并可用于保护任何应用程序的安全—从命令行应用程序

Shrio 快速开始

10分钟快速开始

看到shrio github中有quickstart github地址：https://github.com/apache/shiro/tree/main/samples/quickstart

进入github

quickstart中有src目录和pom.xml

首先看需要导入的maven依赖：

 <dependencies>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
        </dependency>

        <!-- configure logging -->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>jcl-over-slf4j</artifactId>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-slf4j-impl</artifactId>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <scope>runtime</scope>
        </dependency>
    </dependencies>

导入依赖后：

查看src中的resources有什么文件：

可以看到有Log4j2的配置文件，和shiro的配置文件

log4j的配置文件可以网上找一个properties的日志配置文件

shiro的配置文件可以之间复制，毕竟首要是跑起来。

然后直接java目录中的QuickStart.java文件运行就行了（其中有一些类已经过时了）

正确的如下：

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.realm.text.IniRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;


/**
 * Simple Quickstart application showing how to use Shiro's API.
 *
 * @since 0.9 RC2
 */
public class Quickstart {

    private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);


    public static void main(String[] args) {
        DefaultSecurityManager securityManager = new DefaultSecurityManager();
        IniRealm iniRealm = new IniRealm("classpath:shiro.ini");
        securityManager.setRealm(iniRealm);
        SecurityUtils.setSecurityManager(securityManager);

        // Now that a simple Shiro environment is set up, let's see what you can do:

        // get the currently executing user:
            //获取当前的用户对象subject
        Subject currentUser = SecurityUtils.getSubject();

        // Do some stuff with a Session (no need for a web or EJB container!!!)

        //通过当前用户拿到session
        Session session = currentUser.getSession();
        session.setAttribute("someKey", "aValue");
        String value = (String) session.getAttribute("someKey");
        if (value.equals("aValue")) {
            log.info("Session=>" + value + "]");
        }

        // let's login the current user so we can check against roles and permissions:
        //判断当前用户是否登录
        if (!currentUser.isAuthenticated()) {
            //token令牌
            UsernamePasswordToken token = new UsernamePasswordToken("lonestarr22", "vespa");
            token.setRememberMe(true);//remember me
            try {
                currentUser.login(token);//执行登录
            } catch (UnknownAccountException uae) {
                log.info("There is no user with username of " + token.getPrincipal());
            } catch (IncorrectCredentialsException ice) {
                log.info("Password for account " + token.getPrincipal() + " was incorrect!");
            } catch (LockedAccountException lae) {
                log.info("The account for username " + token.getPrincipal() + " is locked.  " +
                        "Please contact your administrator to unlock it.");
            }
            // ... catch more exceptions here (maybe custom ones specific to your application?
            catch (AuthenticationException ae) {
                //unexpected condition?  error?
            }
        }

        //say who they are:
        //print their identifying principal (in this case, a username):
        log.info("User [" + currentUser.getPrincipal() + "] logged in successfully.");

        //test a role:
        if (currentUser.hasRole("schwartz")) {
            log.info("May the Schwartz be with you!");
        } else {
            log.info("Hello, mere mortal.");
        }

        //test a typed permission (not instance-level)
        if (currentUser.isPermitted("lightsaber:wield")) {
            log.info("You may use a lightsaber ring.  Use it wisely.");
        } else {
            log.info("Sorry, lightsaber rings are for schwartz masters only.");
        }

        //a (very powerful) Instance Level permission:
        if (currentUser.isPermitted("winnebago:drive:eagle5")) {
            log.info("You are permitted to 'drive' the winnebago with license plate (id) 'eagle5'.  " +
                    "Here are the keys - have fun!");
        } else {
            log.info("Sorry, you aren't allowed to drive the 'eagle5' winnebago!");
        }

        //all done - log out!
        currentUser.logout();

        System.exit(0);
    }
}

然后运行就行了。
