让我们开始springboot-09 shiro的hello shiro教程。我们将从创建一个简单的maven项目开始，然后逐步搭建shiro环境。
- 创建一个简单的Maven项目
首先，我们需要创建一个最基本的Maven项目。
- 导入依赖
接下来，我们需要在pom.xml中添加以下依赖：
org.apache.shiro shiro-core 1.7.0 org.slf4j jcl-over-slf4j 2.0.0-alpha1 org.slf4j slf4j-log4j12 2.0.0-alpha1 log4j log4j 1.2.17
- 创建log4j.properties
为了配置日志，我们需要创建log4j.properties文件：
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
- 创建shiro.ini
创建shiro.ini文件来配置Shiro的用户和角色：
[users] root = secret, admin guest = guest, guest presidentskroob = 12345, president darkhelmet = ludicrousspeed, darklord, schwartz lonestarr = vespa, goodguy, schwartz[roles] admin = schwartz = lightsaber: goodguy = winnebago:drive:eagle5
- 创建Quickstart类
最后，我们创建一个Quickstart类来测试Shiro的功能：
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) { // The easiest way to create a Shiro SecurityManager with configured // realms, users, roles and permissions is to use the simple INI config. // We'll do that by using a factory that can ingest a .ini file and // return a SecurityManager instance: // Use the shiro.ini file at the root of the classpath // (file: and url: prefixes load from files and urls respectively): FactoryzuojiankuohaophpcnSecurityManageryoujiankuohaophpcn factory = new IniSecurityManagerFactory("classpath:shiro.ini"); SecurityManager securityManager = factory.getInstance(); // for this simple example quickstart, make the SecurityManager // accessible as a JVM singleton. Most applications wouldn't do this // and instead rely on their container configuration or web.xml for // webapps. That is outside the scope of this simple quickstart, so // we'll just do the bare minimum so you can continue to get a feel // for things. SecurityUtils.setSecurityManager(securityManager); // Now that a simple Shiro environment is set up, let's see what you can do: // get the currently executing user: 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 + "]"); } // let's login the current user so we can check against roles and permissions: 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); }}
- 启动测试
- 可能遇到错误
解决办法：
这是因为依赖中的问题。将以下依赖的
scope标签删除：org.slf4j jcl-over-slf4j 2.0.0-alpha1 org.slf4j slf4j-log4j12 2.0.0-alpha1 Shiro环境搭建
Shiro环境搭建需要三个要素：
- ShiroFilterFactoryBean
- DefaultWebSecurityManager
- Realm
我们需要倒着来创建。
创建config文件夹和ShiroConfig、UserRealm类
首先，创建
UserRealm类：public class UserRealm extends AuthorizingRealm { // 授权 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { return null; }//认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { return null; }}
然后，创建
ShiroConfig类：@Configuration public class ShiroConfig { //ShiroFilterFactoryBean @Bean public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier("defaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){ ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean(); //设置安全管理器 bean.setSecurityManager(defaultWebSecurityManager); return bean; }//DefaultWebSecurityManager @Bean public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){ DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); securityManager.setRealm(userRealm); return securityManager; } //创建 realm 对象 @Bean public UserRealm userRealm(){ return new UserRealm(); }}
这样，我们就完成了SpringBoot-09 Shiro的Hello Shiro教程的基本步骤。接下来，您可以根据需要进一步扩展和配置Shiro的功能。
