springboot-shiro:hello world

1 创建一个普通的maven项目

2 引入依赖

pom.xml

<!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-core -->
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-core</artifactId>
    <version>1.8.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.slf4j/jcl-over-slf4j -->
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jcl-over-slf4j</artifactId>
    <version>1.7.36</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-log4j12 -->
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.7.36</version>
</dependency>
<!-- https://mvnrepository.com/artifact/log4j/log4j -->
<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>

3 在resources目录下编写shiro.ini文件

src/main/resources/shiro.ini

[users]
# user 'root' with password 'secret' and the 'admin' role
root = secret, admin
# user 'guest' with the password 'guest' and the 'guest' role
guest = guest, guest
# user 'presidentskroob' with password '12345' ("That's the same combination on
# my luggage!!!" ;)), and role 'president'
presidentskroob = 12345, president
# user 'darkhelmet' with password 'ludicrousspeed' and roles 'darklord' and 'schwartz'
darkhelmet = ludicrousspeed, darklord, schwartz
# user 'lonestarr' with password 'vespa' and roles 'goodguy' and 'schwartz'
lonestarr = vespa, goodguy, schwartz

# -----------------------------------------------------------------------------
# Roles with assigned permissions
#
# Each line conforms to the format defined in the
# org.apache.shiro.realm.text.TextConfigurationRealm#setRoleDefinitions JavaDoc
# -----------------------------------------------------------------------------
[roles]
# 'admin' role has all permissions, indicated by the wildcard '*'
admin = *
# The 'schwartz' role can do anything (*) with any lightsaber:
schwartz = lightsaber:*
# The 'goodguy' role is allowed to 'drive' (action) the winnebago (type) with
# license plate 'eagle5' (instance specific id)
goodguy = winnebago:drive:eagle5

4 在resources目录下编写log4j.properties文件

src/main/resources/log4j.properties

log4j.rootLogger=INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m %n
# General Apache libraries
log4j.logger.org.apache=WARN
# Spring
log4j.logger.org.springframework=WARN
# Default Shiro logging
log4j.logger.org.apache.shiro=INFO
# Disable verbose logging
log4j.logger.org.apache.shiro.util.ThreadContext=WARN
log4j.logger.org.apache.shiro.cache.ehcache.EhCache=WARN

5 编写一个Quickstart

src/main/java/Quickstart.java

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.config.IniSecurityManagerFactory;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.Factory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
 * 类的描述:
 * Simple Quickstart application showing how to use Shiro's API.
 * 简单的快速启动应用程序,演示如何使用Shiro的API。
 */
public class Quickstart {
    //使用log日志输出
    private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);
    public static void main(String[] args) {
        //通过工厂模式读取shiro.ini配置文件,创建SecurityManager的实例对象
        Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
        SecurityManager securityManager = factory.getInstance();
        SecurityUtils.setSecurityManager(securityManager);

        //获取当前的用户对象Subject
        Subject currentUser = SecurityUtils.getSubject();

        //通过当前用户拿到session
        Session session = currentUser.getSession();
        //在session中存值
        session.setAttribute("someKey", "aValue");
        //从session中取值
        String value = (String) session.getAttribute("someKey");
        //输入在session中取出的值
        if (value.equals("aValue")){
            log.info("Subject=>session[" + value + "]");
        }

        //判断当前的用户是否被认证~
        if (!currentUser.isAuthenticated()){
            //Token : 令牌,没有获取,随机
            UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
            token.setRememberMe(true);//设置记住我
            try {
                currentUser.login(token);//执行了登录操作~可以登录成功的情况
            } catch (UnknownAccountException uae) {//用户名不存在的异常
                log.info("There is no user with username of " + token.getPrincipal());
            } catch (IncorrectCredentialsException ice) {//密码错误的异常
                log.info("Password for account " + token.getPrincipal() + " was incorrect!");
            } catch (LockedAccountException lae) {//用户被锁定的异常
                log.info("The account for username " + token.getPrincipal() + " is locked. " + "Please contact your administrator to unlock it.");
            } catch (AuthenticationException ae) { //身份验证异常,上面的异常都是它的子类

            }
        }

        //存储当前用户信息的
        log.info("User [" + currentUser.getPrincipal() + "] logged in successfully.");

        //角色检查,是否存在某一个角色
        if (currentUser.hasRole("schwartz")) {//是否存在某一个角色
            log.info("May the Schwartz be with you!");
        } else {
            log.info("Hello, mere mortal.");
        }

        //粗粒度权限检查:测试用户是否具有某一个权限,行为
        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.");
        }

        //细粒度 权限检查:测试用户是否具有某一个权限,行为,比上面更加的具体
        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!");
        }

        //执行注销操作
        currentUser.logout();

        //退出系统
        System.exit(0);
    }
}

6 运行项目.查看控制台
