本篇博客主要讲述的是两者的集成。不涉及到各自的详细细节和功能。

因为官方给出的文档不够具体,对新手而言通过官方文档还不可以非常快的搭建出SpringShiro的webproject。本博客将通过实际的案例提供具体的教程。

案例分析:

项目名称:假期系统

组织机构:部门 > 小组

角色:Admin, SeniorManager,TeamLeader,Developer

资源:假期Leave

权限:申请Apply,审核Review, 复核ReReview。查看View

角色级别:Admin > Senior Manager >Team Leader > Developer

角色权限:

 

Admin

Senior Manager

Team Leader

Developer

Apply

Review

特殊需求:

1. 角色能够绑定到不同的组织机构级别,比方SeniorManager 是基于部门的,TeamLeader则是基于小组的

2. 角色的级别关系仅仅能在同样的部门中,不同部门之间的角色没有关联

3. 审核仅仅能是自己上级角色审核,复核必须是审核者的上级角色复核,即Developer提出的请假申请仅仅能TeamLeader来审核,而且由SeniorManager复核。

项目搭建

Maven Project: pom.xml

新建一个maven项目,packaging设定为war,设定Spring和Shiro的版本号为3.1.4.RELEASE和1.2.3。并加入必要的依赖。

从配置文件能够看出我们要实现两个重要的模块。一个是CredentialsMatcher, 另外一个叫做Realm。CredentialsMatcher是用来验证password的正确性,Realm则是来获取用户授权和认证的信息。

<!-- 凭证匹配器 -->
<bean id="credentialsMatcher" class="com.xx.shiro.demo.credentials.DemoCredentialsMatcher">
<property name="retry" value="3"/>
<property name="hashAlgorithmName" value="md5"/>
<property name="hashIterations" value="2"/>
<property name="storedCredentialsHexEncoded" value="true"/>
</bean><!-- Realm实现 -->
<bean id="xxDemoRealm" class="com.xx.shiro.demo.realm.XxDemoRealm">
<property name="credentialsMatcher" ref="credentialsMatcher"/>
<property name="userService" ref="userService" />
</bean>

首先来看一下自己定义的Realm,

它继承了抽象类AuthorizingRealm,同一时候AuthorizingRealm又继承了抽象类AuthenticatingRealm,所以自己定义的Realm中要实现两个抽象方法。一个是获取认证信息。另外一个是获取授权信息。详细例如以下:

public class XxDemoRealm extends AuthorizingRealm {  UserService userService;
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
if (principals == null) {
throw new AuthorizationException("PrincipalCollection method argument cannot be null.");
} String username = (String)principals.getPrimaryPrincipal(); SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
authorizationInfo.setRoles(userService.findRoles(username));
authorizationInfo.setStringPermissions(userService.findPermissions(username));
return authorizationInfo;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token)
throws AuthenticationException {
UsernamePasswordToken upToken = (UsernamePasswordToken) token;
String username = upToken.getUsername(); if (username == null) {
throw new AccountException("Null usernames are not allowed by this realm.");
} String[] pwdSalt = userService.getUserPasswordAndSalt(username);
if (pwdSalt == null) {
throw new AccountException("No account found for user [" + username + "]");
} return new SimpleAuthenticationInfo(username, pwdSalt[0].toCharArray(),
ByteSource.Util.bytes(username + pwdSalt[1]), getName()); }
public void setUserService(UserService userService) {
this.userService = userService;
}
}

这里我们分别返回SimpleAuthenticationInfo和SimpleAuthorizationInfo。SimpleAuthenticationInfo是由username,登录password,password盐以及realm名称组成,而SimpleAuthorizationInfo继承与SimpleAuthenticationInfo。同一时候又包括了角色和权限的集合。

在spring的配置中我们定义自己定义realm的时候指定了凭证匹配器:

<bean id="xxDemoRealm" class="com.xx.shiro.demo.realm.XxDemoRealm">
<property name="credentialsMatcher" ref="credentialsMatcher"/>
<property name="userService" ref="userService" />
</bean>

凭证匹配器就是用来验证用户输入的帐号password和数据库中的password是否匹配。

public class DemoCredentialsMatcher extends HashedCredentialsMatcher {  // 这里应该用cache来做, 不要用Map
private static Map<String, AtomicInteger> cache = new HashMap<String, AtomicInteger>(); private int retry = 5; @Override
public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
String username = (String) token.getPrincipal();
AtomicInteger retryCount = cache.get(username);
if (retryCount == null) {
retryCount = new AtomicInteger(0);
cache.put(username, retryCount);
}
if (retryCount.incrementAndGet() > retry) {
throw new ExcessiveAttemptsException();
}
boolean matches = super.doCredentialsMatch(token, info);
if (matches) {
cache.remove(username);
}
return matches;
} public void setRetry(int retry) {
this.retry = retry;
}}

我们这里使用的是HashedCredentialsMatcher,另外加入了重试最大次数的机制。失败几次之后就不能登录了,解锁这里没有涉及到。
