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：
<dependencies>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.7.0</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>2.0.0-alpha1</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>2.0.0-alpha1</version>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
</dependencies>- 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 <p>[roles] admin = <em> schwartz = lightsaber:</em> 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;</p><p>public class Quickstart {
private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);</p><pre class="brush:php;toolbar:false;"><code>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):
Factory<SecurityManager> 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：
<dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> <version>2.0.0-alpha1</version> <!-- <scope>test</scope> --> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>2.0.0-alpha1</version> <!-- <scope>test</scope> --> </dependency>
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;
}</p><pre class="brush:php;toolbar:false;"><code>//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;
}</p><pre class="brush:php;toolbar:false;"><code>//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。
