Shiro —— Spring 环境下的使用
一、使用
1.搭建基础环境
（1）导入 Spring 和 Shiro 的 Jar 包
- 正常导入 spring jar包
- 导入日志包
- log4j-1.2.15.jar
- slf4j-api-1.6.1.jar
- slf4j-log4j12-1.6.1.jar
- 导入 shiro 包
- shiro-core-1.2.2.jar
- shiro-ehcache-1.2.2.jar
- shiro-spring-1.2.2.jar
- shiro-web-1.2.2.jar
（2）配置文件
- web.xml
- 读取所有配置文件
- springmvc 的 DispatcherServlet 配置
- shiroFilter 的配置（该配置参考的是：shiro-root-1.2.2\samples\spring\src\main\webapp\WEB-INF\web.xml）
- 见文章末的两个 web.xml
- spring-shiro.xml
- 该配置参考：shiro-root-1.2.2\samples\spring\src\main\webapp\WEB-INF\applicationContext.xml
- 此次实验在 shiro.xml 文件中采用的缓存管理器是 ehcache 。需要额外导入ehcache jar包和配置文件。
- ehcache 使用的 Hibernate 下的。
- ehcache-core-2.4.3.jar（hibernate-release-4.2.4.Final\lib\optional\ehcache\） 和 ehcache.xml（hibernate-release-4.2.4.Final\project\etc\）
- 见文章末的两个 spring-shiro.xml
- 注意：（1）缓存的配置（2）自定义Realm
- spring.xml 正常配置即可。
- springmvc.xml 正常配置即可。
（3）检测
- 添加自定义 Realm，需要继承自 AuthorizingRealm（即包含认证，也包含授权的 Realm）
- 添加了一个空的自定义的 Realm ，没有添加认证和授权逻辑。
- 启动项目，检测能否正常启动，检测配置是否正确。
2.登录
（1）添加登录页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head> <title>Title</title></head><body> <h4> Login Page </h4> <form action="shiro-login" method="post"> <input name="userName" type="text"/> <input name="password" type="password"/> <input type="submit" value="submit"> </form></body></html>
（2）对应 Handler 方法
@RequestMapping("/shiro-login")public String login(String userName, String password) { System.out.println("userName:" + userName + ", password:" + password); Subject currentUser = SecurityUtils.getSubject(); if(!currentUser.isAuthenticated()) { UsernamePasswordToken token = new UsernamePasswordToken(userName, password); token.setRememberMe(true); try { currentUser.login(token); } catch(UnknownAccountException uae) { System.out.println("用户名不正确！"); } catch(IncorrectCredentialsException ice) { System.out.println("密码不匹配！"); } catch(LockedAccountException lae) { System.out.println("账户被锁定!"); } catch(AuthenticationException ae) { System.out.println("认证失败!"); } } return "success";}这里参考的是官方的 demo :shiro-root-1.2.2\samples\quickstart\src\main\java\Quickstart.java

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); }}
说明一下：
官方 demo 演示的是一个 java 项目，而不是一个 web 项目，不同点是：web 项目下，shiro 的大管家是由容器去创建的，而不需要我们手动去获取。
（3）检测能否正常运行，若能，则证明登录测试成功。
3.认证
（1）实现自定义 Realm 的 认证方法。
@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("开始认证！"); UsernamePasswordToken upToken = (UsernamePasswordToken) token; String username = upToken.getUsername(); Object credentials = "123456"; SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(username, credentials, this.getName()); return info;}
或
@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("开始认证！"); UsernamePasswordToken upToken = (UsernamePasswordToken) token; String username = upToken.getUsername(); User user = new User(); user.setId(1000); user.setUserName(username); user.setPassword("123456"); user.getRoleNames().add("admin"); return new SimpleAuthenticationInfo(user, user.getPassword(), this.getName());}
说明一下：
其中 username 是从页面获取到的，而密码是通过查询数据库获取的。注意标红加粗的地方。
实现的参考：org.apache.shiro.realm.jdbc.JdbcRealm
（2）测试，此时密码不为 "123456"能否登录。测试认证是否成功。
4.授权
（1）实现自定义 Realm 的授权方法。
@Overrideprotected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { System.out.println("开始授权!"); String username = (String)this.getAvailablePrincipal(principalCollection); System.out.println("userName:" + username); Set<String> roleNames = new HashSet<>(); roleNames.add("admin"); SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(roleNames); return info;}
或：User 对象已经包含角色信息，不需要再次查询数据库。
@Overrideprotected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { System.out.println("开始授权!"); User user = (User) principalCollection.getPrimaryPrincipal(); Set<String> roleNames = user.getRoleNames(); return new SimpleAuthorizationInfo(roleNames);}
实现的参考：org.apache.shiro.realm.jdbc.JdbcRealm
（2）测试，添加对应的页面，然后在 Shiro 配置文件中配置访问对应的页面需要什么样的角色才能访问。
5.认证和授权的资源数据从数据库中获取
（1）受保护资源和需要角色权限间的关系存在在 shiro.xml 文件中。
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager"/> <property name="loginUrl" value="/login.jsp"/> <property name="unauthorizedUrl" value="/unauthorized.jsp"/> <property name="filterChainDefinitions"> <value> /user.jsp = authc /admin.jsp = roles[admin] /** = anon </value> </property></bean>
（2）要想改为从数据库中获取，思路就是：filterChainDefinitions 属性值能从 Java 文件中获取。
参看：filterChainDefinitions 属性的官方使用
public void setFilterChainDefinitions(String definitions) { Ini ini = new Ini(); ini.load(definitions); Section section = ini.getSection("urls"); if(CollectionUtils.isEmpty(section)) { section = ini.getSection(""); } this.setFilterChainDefinitionMap(section);}public void setFilterChainDefinitionMap(Map<String, String> filterChainDefinitionMap) { this.filterChainDefinitionMap = filterChainDefinitionMap;}
实际上放的是一个 Map。那么来看看具体的 Map 存放的是怎么的一些数据格式？在标红的代码处打个断点，可以看到如下内容：
可以看到, Map 内容的就是在 shiro.xml 通过属性 filterChainDefinitions 定义的值。
（3）具体操作
/** * @author solverpeng * @create 2016-09-21-18:59 */public class FilterChainDefinitionMapBuilder { public Map<String, String> getFilterChainDefinitionMap() { Map<String, String> filterChainDefinitionMap = new HashMap<>(); filterChainDefinitionMap.put("/admin.jsp", "roles[admin],authc"); filterChainDefinitionMap.put("/user.jsp", "authc"); filterChainDefinitionMap.put("/**", "anon"); return filterChainDefinitionMap; }}
更改配置：
<bean id="filterChainDefinitionMapBuilder" class="com.nucsoft.shiro.shiro.FilterChainDefinitionMapBuilder"/><bean id="filterChainDefinitionMap" factory-bean="filterChainDefinitionMapBuilder" factory-method="getFilterChainDefinitionMap"/><bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager"/> <property name="loginUrl" value="/login.jsp"/> <property name="unauthorizedUrl" value="/unauthorized.jsp"/> <property name="filterChainDefinitionMap" ref="filterChainDefinitionMap"/></bean>
此时，资源信息可以通过 Java 方法来处理，而此时，这些数据就可以从数据库中获取。
6.盐值加密
加密指的是对密码的加密，用户注册时，将密码使用一定的加密方式存放到数据库中，用户登录的时候，同样以相同的加密方式进行比对。
在什么地方进行的对比？
注意：不是在自定义认证的时候对比的。在 MyRealm 中
@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("开始认证！"); UsernamePasswordToken upToken = (UsernamePasswordToken) token; String username = upToken.getUsername(); User user = new User(); user.setId(1000); user.setUserName(username); user.setPassword("42e56621cf3adc9ecc261936188d31d7"); user.getRoleNames().add("admin"); String hashedCredentials = user.getPassword(); ByteSource credentialsSalt = ByteSource.Util.bytes("abcd"); String realmName = getName(); SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, hashedCredentials, credentialsSalt, realmName); return info;}
的这个方法的作用，只是根据传入的 Token 获取到 username，从而到数据库中查询对应的 User 对象，以及盐值信息，然后返回封装这些信息的 SimpleAuthenticationInfo 的对象。
密码的对比是在这之后对比的，来看返回后，返回到了 org.apache.shiro.realm.AuthenticatingRealm#getAuthenticationInfo 这个方法
public final AuthenticationInfo getAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { AuthenticationInfo info = getCachedAuthenticationInfo(token); if (info == null) { //otherwise not cached, perform the lookup: info = doGetAuthenticationInfo(token); log.debug("Looked up AuthenticationInfo [{}] from doGetAuthenticationInfo", info); if (token != null && info != null) { cacheAuthenticationInfoIfPossible(token, info); } } else { log.debug("Using cached authentication info [{}] to perform credentials matching.", info); } if (info != null) { assertCredentialsMatch(token, info); } else { log.debug("No AuthenticationInfo found for submitted AuthenticationToken [{}]. Returning null.", token); } return info;}
其中第一处标红的地方是调用我们自定义 Realm 的 doGetAuthenticationInfo() 方法以及返回值。
第二处标红的地方表示如果可以缓存的话，就把此登录账户进行缓存。
第三处才是真正进行比较的地方，看看方法名和参数，见名知意。 token 为表单提交过来的用户信息，而 info 是我们做认证时从数据库查询获取到的。
详细来看：org.apache.shiro.realm.AuthenticatingRealm#assertCredentialsMatch
protected void assertCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) throws AuthenticationException { CredentialsMatcher cm = getCredentialsMatcher(); if (cm != null) { if (!cm.doCredentialsMatch(token, info)) { //not successful - throw an exception to indicate this: String msg = "Submitted credentials for token [" + token + "] did not match the expected credentials."; throw new IncorrectCredentialsException(msg); } } else { throw new AuthenticationException("A CredentialsMatcher must be configured in order to verify " + "credentials during authentication. If you do not wish for credentials to be examined, you " + "can configure an " + AllowAllCredentialsMatcher.class.getName() + " instance."); }}
两个核心的地方：
第一处标红是：获取凭证的匹配器（密码的匹配器），来看这个接口中封装了一下什么信息。
public interface CredentialsMatcher { boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info);}
只有一个 doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) 的方法。
来看它的体系：
看到了 Md5CredentialsMatcher, 然后发现它是一个过期的类，HashedCredentialsMatcher 作为对它的一个替代，需要 setHashAlgorithmName() 来指定加密方式。
这里直接对 HashedCredentialsMatcher 给出说明：
（1）加密方式：setHashAlgorithmName(String hashAlgorithmName)
（2）加密次数：setHashIterations(int hashIterations)
说了这么多，如何由我们自己指定 CreaentialsMatcher ？
我自定义的 MyRealm 是 AuthenticatingRealm 它的子类，所以想法是，在 AuthenticatingRealm 调用 getCredentialsMatcher() 之前，就将 CreaentialsMatcher set到 Realm 中。
来看具体操作：
在 MyRealm 中定义一个初始化方法：
public void initCredentialsMatcher() { HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher(); credentialsMatcher.setHashAlgorithmName("MD5"); credentialsMatcher.setHashIterations(1000); setCredentialsMatcher(credentialsMatcher);}
指定了加密方式，然后加密次数，然后设置到了 Realm 中。
为了保证在在 AuthenticatingRealm 调用 getCredentialsMatcher() 之前，就将 CreaentialsMatcher set到 Realm 中，在容器初始化的时候就设置。
applicationContext-shiro.xml 的配置：
<bean id="realm" class="com.nucsoft.shiro.shiro.MyRealm" init-method="initCredentialsMatcher"/>
第二处标红进行的真正的密码匹配：cm.doCredentialsMatch(token, info)
详细来看：org.apache.shiro.authc.credential.HashedCredentialsMatcher#doCredentialsMatch
public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) { Object tokenHashedCredentials = hashProvidedCredentials(token, info); Object accountCredentials = getCredentials(info); return equals(tokenHashedCredentials, accountCredentials);}
其中 tokenHashedCredentials 是从表单提交过来的密码经同样的加密方式处理后的凭证；accountCredentials 是从数据库中取出来的凭证信息。
关注点：是怎么对表单密码进行加密处理的
详细来看：
org.apache.shiro.authc.credential.HashedCredentialsMatcher#hashProvidedCredentials(org.apache.shiro.authc.AuthenticationToken, org.apache.shiro.authc.AuthenticationInfo)
protected Object hashProvidedCredentials(AuthenticationToken token, AuthenticationInfo info) { Object salt = null; if (info instanceof SaltedAuthenticationInfo) { salt = ((SaltedAuthenticationInfo) info).getCredentialsSalt(); } else { //retain 1.0 backwards compatibility: if (isHashSalted()) { salt = getSalt(token); } } return hashProvidedCredentials(token.getCredentials(), salt, getHashIterations());}
org.apache.shiro.authc.credential.HashedCredentialsMatcher#hashProvidedCredentials(java.lang.Object, java.lang.Object, int)
protected Hash hashProvidedCredentials(Object credentials, Object salt, int hashIterations) { String hashAlgorithmName = assertHashAlgorithmName(); return new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations);}
hashAlgorithmName：这个就是在凭证匹配器中定义的加密方式。
核心：进行加密的就是这个：
new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations)
hashAlgorithmName: 加密方式
credentials:表单提交的密码
salt:盐值
hashIterations:加密次数
用户注册的时候，向数据库存入密码的时候，可以使用此种方式对密码进行加密。
来看一个测试：
public static void main(String[] args) { String hashAlgorithmName = "MD5"; Object credentials = "123456"; ByteSource salt = ByteSource.Util.bytes("abcd"); int hashIterations = 1000; SimpleHash simpleHash = new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations); System.out.println(simpleHash);}
说了这么多，还没有说 自定义认证方法的盐值是如何添加的：
com.nucsoft.shiro.shiro.MyRealm#doGetAuthenticationInfo
来看：
@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("开始认证！"); UsernamePasswordToken upToken = (UsernamePasswordToken) token; String username = upToken.getUsername(); User user = new User(); user.setId(1000); user.setUserName(username); user.setPassword("42e56621cf3adc9ecc261936188d31d7"); user.getRoleNames().add("admin"); String hashedCredentials = user.getPassword(); ByteSource credentialsSalt = ByteSource.Util.bytes("abcd"); String realmName = getName(); SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, hashedCredentials, credentialsSalt, realmName); return info;}
标红的地方就是加盐值后的处理方式。
在注册的时候，随机生成盐值，同用户信息存入数据库中。
7.关于细粒度的基于注解的授权和基于标签库的授权，本篇文章不进行说明。
二、总结
介绍了 Spring 环境下 shiro 的使用，包括环境的搭建，以及是如何配置的，自定义 Realm 可以完成自定义认证和自定义授权，也可以完成凭证匹配器的设置。
以及具体是怎么完成自定义认证和授权的，也将受保护的资源与访问的权限从xml文件中转到了 java 类中，为后续从数据库中读取提供了方便。
也介绍了加密的方式：加密类型，加密次数，加密盐值，以及具体是如何加密的。并没有讲明在真实项目中是如何使用的，以后有机会写文章来说明。

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="cacheManager" ref="cacheManager"/> <property name="realm" ref="realm"/> </bean> <bean id="realm" class="com.nucsoft.shiro.shiro.MyRealm"/> <bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager"> <property name="cacheManagerConfigFile" value="classpath:ehcache-shiro.xml"/> </bean> <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/> <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/> <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"> <property name="securityManager" ref="securityManager"/> </bean> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager"/> <property name="loginUrl" value="/login.jsp"/> <property name="unauthorizedUrl" value="/unauthorized.jsp"/> <property name="filterChainDefinitions"> <value> /user.jsp = authc /admin.jsp = roles[admin] /** = anon </value> </property> </bean></beans>
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="cacheManager" ref="cacheManager"/> <property name="realm" ref="realm"/> </bean> <bean id="realm" class="com.nucsoft.shiro.shiro.MyRealm"/> <bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager"> <property name="cacheManagerConfigFile" value="classpath:ehcache-shiro.xml"/> </bean> <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/> <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/> <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"> <property name="securityManager" ref="securityManager"/> </bean> <bean id="filterChainDefinitionMapBuilder" class="com.nucsoft.shiro.shiro.FilterChainDefinitionMapBuilder"/> <bean id="filterChainDefinitionMap" factory-bean="filterChainDefinitionMapBuilder" factory-method="getFilterChainDefinitionMap"/> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager"/> <property name="loginUrl" value="/login.jsp"/> <property name="unauthorizedUrl" value="/unauthorized.jsp"/> <property name="filterChainDefinitionMap" ref="filterChainDefinitionMap"/> </bean></beans>
3.springmvc.xml
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <context:component-scan base-package="com.nucsoft.shiro.handler"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/pages/"/> <property name="suffix" value=".jsp"/> </bean> <mvc:annotation-driven/> <mvc:default-servlet-handler/></beans>
四、shiro 中默认的过滤器名称以及使用
1.anno，匿名就可以访问，e:/admins/** = anno
2.authc，认证后可以访问，e:/user/** = authc
3.authcBasic，没有参数，表示需要通过 httpBasic 验证，如果不通过，跳转到登录页面。e:/user/** = authcBasic
4.logout
5.noSessionCreation，阻止在请求期间创建新的会话，以保证无状态的体验。
6.perms，e1:/admins/**=perms[user:add:*] ，e2:/admins/users/**=perms["user:add:*,user:modify:*"]
7.post，指定请求访问的端口，e:/admins/**=port[8080]
8.rest，根据请求的方法，e:/admins/user/**=perms[user.method]，其中mothod 为 post,get,delete 等。
9.roles，角色过滤器，判断当前用户是否拥有指定的角色。
10.ssl，没有参数，表示协议为 https。
11.user，表示必须存在用户。
