1.创建普通maven项目，导入依赖。

    
        org.apache.shiro
        shiro-core
        1.4.1
    
    
    
        org.slf4j
        jcl-over-slf4j
        1.7.21
    
    
        org.slf4j
        slf4j-log4j12
        1.7.25
    
    
        log4j
        log4j
        1.2.17
    

2.导入log4j.properties和shrio.ini

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

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]
# '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

3、 直接复制官网上的Quickstart.java,运行

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;

public class Quickstart {

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


    public static void main(String[] args) {

        Factory factory = new IniSecurityManagerFactory("classpath:shiro.ini");
        SecurityManager securityManager = factory.getInstance();

      
        SecurityUtils.setSecurityManager(securityManager);

        Subject currentUser = SecurityUtils.getSubject();

        // Do some stuff with a Session (no need for a web or EJB container!!!)
        Session session = currentUser.getSession();
        session.setAttribute("someKey", "aValue");
        String value = (String) session.getAttribute("someKey");
        if (value.equals("aValue")) {
            log.info("Retrieved the correct value! [" + value + "]");
        }

        
        if (!currentUser.isAuthenticated()) {
            UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
            token.setRememberMe(true);
            try {
                currentUser.login(token);
            } 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);
    }
}

4.总结。

 获取subject对象：Subject currentUser = SecurityUtils.getSubject();
通过当前对象得到session：Session session = currentUser.getSession();
判断当前用户是否被认证：currentUser.isAuthenticated()
登录： currentUser.login(token);
登出： currentUser.logout(token);
获取当前用户的认证：currentUser.getPrincipal()
当前用户是否拥有指定角色：currentUser.hasRole(“schwartz”)
获取当前用户的权限：currentUser.isPermitted(“lightsaber:wield”

三、springboot集成Shiro

1.依赖导入pox.xml.

        集成Shiro的过程中整合了MyBatis、thymeleaf

        
        
            com.github.theborakompanioni
            thymeleaf-extras-shiro
            2.0.0
        

        
        
            com.alibaba
            druid
            1.2.6
        

        
            mysql
            mysql-connector-java
            runtime
        
        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            2.1.3
        
        
        
            log4j
            log4j
            1.2.17
        
        
        
        
            org.apache.shiro
            shiro-spring
            1.4.1
        
        
            org.springframework.boot
            spring-boot-starter-web
        
        
        
            org.springframework.boot
            spring-boot-starter-thymeleaf
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        
        
        
            org.projectlombok
            lombok
            1.18.12
            provided
        
    

2、编写配置类ShiroConfig

@Configuration
public class ShiroConfig {

    //ShiroFilterFactoryBean : Step3
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);
        //添加shiro的内置过滤器
        /*
            anno: 无需认证就可以访问
            authc: 必须认证了才可以访问
            user: 必须拥有 记住我 功能才能用
            perms: 拥有对某个资源的权限才能访问
            role: 拥有某个角色权限才能访问
        */
        //拦截
        Map filterMap = new LinkedHashMap<>();

        //授权
        filterMap.put("/user/add","perms[user:add]");
        filterMap.put("/user/update","perms[user:update]");

        filterMap.put("/user/*","authc");
        bean.setFilterChainDefinitionMap(filterMap);

        //设置登录请求
        bean.setLoginUrl("/toLogin");
        //设置未授权的请求
        bean.setUnauthorizedUrl("/noauth");

        return bean;

    }

    //DefaultWebSecurityManager : Step2
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(userRealm);
        return securityManager;
    }

    //创建 realm 对象  需要自定义:Step1

    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }

    //整合 ShiroDialect  用来整合thymeleaf shiro
    @Bean
    public ShiroDialect getShiroDialect(){
        return new ShiroDialect();
    }
}

3、 自定义realm继承AuthorizingRealm

        UserRealm 

//自定义的UserRealm
public class UserRealm extends AuthorizingRealm{
    @Autowired
    UserServiceImpl userService;

    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了 => 授权doGetAuthorizationInfo");
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        //info.addStringPermission("user:add");

        //拿到当前登录的对象
        Subject subject = SecurityUtils.getSubject();
        User user = (User) subject.getPrincipal();



        //设置当前用户权限
        info.addStringPermission(user.getPerms());



        return info;
    }

    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("执行了 => 认证doGetAuthenticationInfo");


        UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;

        //连接真是数据库
        User user = userService.queryByUserName(userToken.getUsername());

        if(user == null){//没有这个人
            return null;//报异常
        }
        // 登录成功 将用户信息存入session
        Subject currentSubject = SecurityUtils.getSubject();
        Session session = currentSubject.getSession();
        session.setAttribute("loginUser",user.getUsername());

        //密码认证，Shiro帮我们认证
        return new SimpleAuthenticationInfo(user,user.getPassword(),"");
    }
}

• controller

@Controller
public class MyController {

    @RequestMapping({"/","/index","/index,html"})
    public String toIndex(Model model){
        model.addAttribute("msg","
hello cvzhanshi
");
        return "index";
    }

    @RequestMapping("/user/add")
    public String add(){
        return "user/add";
    }

    @RequestMapping("/user/update")
    public String update(){
        return "user/update";
    }
    @RequestMapping("/toLogin")
    public String toLogin(){
        return "login";
    }

    @RequestMapping("/login")
    public String login(String username,String password,Model model){
        //获取当前用户
        Subject subject = SecurityUtils.getSubject();
        //封装用户的登录数据
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);

        try {
            subject.login(token);//执行登录的方法，如果没有异常就说明ok了
            return "index";
        }catch (UnknownAccountException accountException){
            // 用户名不存在
            model.addAttribute("msg","用户名错误");
            return "login";
        }catch (IncorrectCredentialsException e){
            // 密码错误
            model.addAttribute("msg","密码错误");
            return "login";
        }
    }

    @RequestMapping("/noauth")
    @ResponseBody
    public String unauthorized(){
        return "未经授权无法访问此页面！";
    }
}

• 实体类User

@Data
@NoArgsConstructor
@AllArgsConstructor
public class User {
    private Integer id;
    private String username;
    private String password;
    private String perms;
}

• index.html

    
    


首页
