Apache Shiro是一个强大且易用的Java安全框架,用来进行身份验证、授权、密码和会话管理。使用Shiro的易于理解API,你可以快速、轻松地获取任何应用程序,从最小的移动应用程序到最大的网络和企业应用程序
shiro架构图:官网架构图
api | 说明 |
---|---|
Subject | 主体,应用代码直接交互的对象是 Subject,也就是说 Shiro 的对外 API 核心就是 Subject , 代表了当前“用户”,这个用户不一定是一个具体的人,与当前应用交互的任何东西都是Subject,如网络爬虫,机器人等;即一个抽象概念;所有Subject都绑定到SecurityManager,与Subject的所有交互都会委托给SecurityManager;可以把Subject认为是一个门面;SecurityManager才是实际的执行者; |
ShiroSecurityManager | 安全管理器,即所有与安全有关的操作都会与SecurityManager交互且它管理着所有Subject;可以看出它是Shiro的核心,它负责与后面介绍的其它组件进行交互,可以把它看成DispathcherServlet前端控制器 |
Realm | 域,Shiro从Realm获取安全数据(如用户、角色、权限),就是说SecurityManager要验证用户身份,那么它需要从Realm获取相应的用户进行比较以确定用户身份是否合法;也需要从Realm得到用户相应的角色/权限进行验证用户是否能进行操作;可以把Realm看成DataSource,即安全数据源 |
也就是说最简单的一个Shiro应用:
1、应用代码通过Subject来进行认证和授权,而Subject又委托给SecurityManager;
2、我们需要给Shiro的SecurityManager注入Realm,从而让SecurityManager能得到合法的用户及其权限进行判断。
从以上也可以看出,Shiro不提供维护用户/权限,而是通过Realm让开发人员自己注入。
组件 | 说明 |
---|---|
Subject | 主体,主体可以是任何可以与应用交互的“用户” |
SecurityManager | 相当于SpringMVC中的DispatcherServlet或者Struts2中的FilterDispatcher;是Shiro的心脏;所有具体的交互都通过SecurityManager进行控制;它管理着所有Subject、且负责进行认证和授权、及会话、缓存的管理 |
Authenticator | 认证器,负责主体认证的,这是一个扩展点,如果用户觉得Shiro默认的不好,可以自定义实现;其需要认证策略(Authentication Strategy),即什么情况下算用户认证通过了 |
Authrizer | 授权器或者访问控制器,用来决定主体是否有权限进行相应的操作;即控制着用户能访问应用中的哪些功能 |
Realm | 可以有1个或多个Realm,可以认为是安全实体数据源,即用于获取安全实体的;可以是JDBC实现,也可以是LDAP实现,或者内存实现等等;由用户提供;注意:Shiro不知道你的用户/权限存储在哪及以何种格式存储;所以我们一般在应用中都需要实现自己的Realm; |
SessionManager | 如果写过Servlet就应该知道Session的概念,Session呢需要有人去管理它的生命周期,这个组件就是SessionManager;而Shiro并不仅仅可以用在Web环境,也可以用在如普通的JavaSE环境、EJB等环境;所有呢,Shiro就抽象了一个自己的Session来管理主体与应用之间交互的数据;这样的话,比如我们在Web环境用,刚开始是一台Web服务器;接着又上了台EJB服务器;这时想把两台服务器的会话数据放到一个地方,这个时候就可以实现自己的分布式会话(如把数据放到Memcached服务器) |
SessionDAO | DAO大家都用过,数据访问对象,用于会话的CRUD,比如我们想把Session保存到数据库,那么可以实现自己的SessionDAO,通过如JDBC写到数据库;比如想把Session放到Memcached中,可以实现自己的Memcached SessionDAO;另外SessionDAO中可以使用Cache进行缓存,以提高性能 |
CacheManager | 缓存控制器,来管理如用户、角色、权限等的缓存的;因为这些数据基本上很少去改变,放到缓存中后可以提高访问的性能 |
Cryptography | 密码模块,Shiro提高了一些常见的加密组件用于如密码加密/解密的 |
当 Shiro 被运用到 web 项目时,Shiro 会自动创建一些默认的过滤器对客户端请求进行过滤。比如身份验证、授权等相关的操作。
过滤器 | 对应的 Java 类 |
---|---|
anon | org.apache.shiro.web.filter.authc.AnonymousFilter |
authc | org.apache.shiro.web.filter.authc.FormAuthenticationFilter |
authcBasic | org.apache.shiro.web.filter.authc.BasicHttpAuthenticationFilter |
perms | org.apache.shiro.web.filter.authz.PermissionsAuthorizationFilter |
port | org.apache.shiro.web.filter.authz.PortFilter |
rest | org.apache.shiro.web.filter.authz.HttpMethodPermissionFilter |
roles | org.apache.shiro.web.filter.authz.RolesAuthorizationFilter |
ssl | org.apache.shiro.web.filter.authz.SslFilter |
user | org.apache.shiro.web.filter.authc.UserFilter |
logout | org.apache.shiro.web.filter.authc.LogoutFilter |
noSessionCreation | org.apache.shiro.web.filter.session.NoSessionCreationFilter |
注意:
anon,authcBasic,auchc,user 是认证过滤器。
perms,roles,ssl,rest,port 是授权过滤器
shiro全局异常 :org.apache.shiro.ShiroException
shiro常见异常分为两大类:
AuthenticationException 异常是Shiro在登录认证过程中,认证失败需要抛出的异常。 AuthenticationException包含以下子类:
IncorrectCredentialsException 不正确的凭证
ExpiredCredentialsException 凭证过期
ConcurrentAccessException 并发访问异常(多个用户同时登录时抛出)
UnknownAccountException 未知的账号
ExcessiveAttemptsException 认证次数超过限制
DisabledAccountException 禁用的账号
LockedAccountException 账号被锁定
UnauthorizedException:抛出对请求的操作或对请求的资源的访问是不允许的
UnanthenticatedException:当未完成成功认证时,执行授权操作时引发异常

多Realm认证策略: AuthenticationStrategy
• AuthenticationStrategy 接口的默认实现:
• FirstSuccessfulStrategy:只要有一个 Realm 验证成功即可,只返回第 一个 Realm 身份验证成功的认证信息,其他的忽略;
• AtLeastOneSuccessfulStrategy:只要有一个Realm验证成功即可,和 FirstSuccessfulStrategy 不同,将返回所有Realm身份验证成功的认证信 息;
• AllSuccessfulStrategy:所有Realm验证成功才算成功,且返回所有 Realm身份验证成功的认证信息,如果有一个失败就失败了。 • ModularRealmAuthenticator 默认是 AtLeastOneSuccessfulStrategy 策略

• 1、首先调用 Subject.login(token) 进行登录,其会自动委托给 SecurityManager
• 2、SecurityManager 负责真正的身份验证逻辑;它会委托给 Authenticator 进行身份验证;
• 3、Authenticator 才是真正的身份验证者,Shiro API 中核心的身份 认证入口点,此处可以自定义插入自己的实现;
• 4、Authenticator 可能会委托给相应的 AuthenticationStrategy 进 行多 Realm 身份验证,默认 ModularRealmAuthenticator 会调用 AuthenticationStrategy 进行多 Realm 身份验证;
• 5、Authenticator 会把相应的 token 传入 Realm,从 Realm 获取 身份验证信息,如果没有返回/抛出异常表示身份验证失败了。此处 可以配置多个Realm,将按照相应的顺序及策略进行访问。

使用注解时shiroFilterFactoryBean.setUnauthorizedUrl无效,无权限或者没登录时页面不跳转,展示不友好页面。
Shiro注解模式下,访问权限注解管理的接口时,没有登录、登录失败与没有权限都是通过抛出异常的,需要用springboot统一异常处理来捕获处理

出现这种情况是因为:SimpleByteSource没有是实现Serializable接口
解决办法:
public class SimpleByteSource extends org.apache.shiro.util.SimpleByteSource implements Serializable {
private static final long serialVersionUID = 7220896367594761367L;
public SimpleByteSource(byte[] bytes) {
super(bytes);
}
}
创建工具类ByteSourceUtils
public class ByteSourceUtils {
public static ByteSource bytes(byte[] bytes){
return new SimpleByteSource(bytes);
}
public static ByteSource bytes(String arg0){
return new SimpleByteSource(arg0.getBytes());
}
}
最后在Realm认证方法中
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
log.info("=====================enter method UserRealm-doGetAuthenticationInfo进行登陆验证");
UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;
LoginUserProfile profile = new LoginUserProfile();
//查询用户
User user = userMapper.getUserByUsername(userToken.getUsername());
if(null == user){
throw new UnknownAccountException("账号不存在,请重试");
}
profile.setUser(user);
SecurityUtils.getSubject().getSession().setAttribute("loginUser",profile);
//加salt返回
//ByteSource salt = ByteSource.Util.bytes(Constants.SALT);
ByteSource salt = ByteSourceUtils.bytes(Constants.SALT);
return new SimpleAuthenticationInfo(profile,user.getPassword(),salt,getName());
}
public class MyByteSource implements ByteSource,Serializable {
private byte[] bytes;
private String cachedHex;
private String cachedBase64;
public MyByteSource() {
}
public MyByteSource(byte[] bytes) {
this.bytes = bytes;
}
public MyByteSource(char[] chars) {
this.bytes = CodecSupport.toBytes(chars);
}
public MyByteSource(String string) {
this.bytes = CodecSupport.toBytes(string);
}
public MyByteSource(ByteSource source) {
this.bytes = source.getBytes();
}
public MyByteSource(File file) {
this.bytes = new MyByteSource.BytesHelper().getBytes(file);
}
public MyByteSource(InputStream stream) {
this.bytes = new MyByteSource.BytesHelper().getBytes(stream);
}
public static boolean isCompatible(Object o) {
return o instanceof byte[] || o instanceof char[] || o instanceof String ||
o instanceof ByteSource || o instanceof File || o instanceof InputStream;
}
@Override
public byte[] getBytes() {
return this.bytes;
}
@Override
public boolean isEmpty() {
return this.bytes == null || this.bytes.length == 0;
}
@Override
public String toHex() {
if ( this.cachedHex == null ) {
this.cachedHex = Hex.encodeToString(getBytes());
}
return this.cachedHex;
}
@Override
public String toBase64() {
if ( this.cachedBase64 == null ) {
this.cachedBase64 = Base64.encodeToString(getBytes());
}
return this.cachedBase64;
}
@Override
public String toString() {
return toBase64();
}
@Override
public int hashCode() {
if (this.bytes == null || this.bytes.length == 0) {
return 0;
}
return Arrays.hashCode(this.bytes);
}
@Override
public boolean equals(Object o) {
if (o == this) {
return true;
}
if (o instanceof ByteSource) {
ByteSource bs = (ByteSource) o;
return Arrays.equals(getBytes(), bs.getBytes());
}
return false;
}
//will probably be removed in Shiro 2.0. See SHIRO-203:
//https://issues.apache.org/jira/browse/SHIRO-203
private static final class BytesHelper extends CodecSupport {
/**
* 嵌套类也需要提供无参构造器
*/
private BytesHelper() {
}
public byte[] getBytes(File file) {
return toBytes(file);
}
public byte[] getBytes(InputStream stream) {

}
}
}
原因:formAuthenticationFilter 在shiroFilterFactoryBean前面加载,而后使用
SecurityUtils.getSubject()时会报这个错,应该放后面去加载;
注意:自定义filter也应该在shiroFilter之后加载;如果将自定义的Filter在ShiroFitler之前加载,ShiroFilter 是整个 Shiro 的入口点,用于拦截需要安全控制的请求进行处理,当自定义的filter先于shiroFilter加载,而shiroFilter里又使用到该自定义filter时,就会导致调用该自定义filter进行预处理时访问不到SecurityManager
UserInfo实体类必须实现序列化接口,否则报序列化异常。因为RememberMe会将用户信息加密然后以Cookie保存
在使用shiro时,ShiroFilterFactoryBean 会依赖注入 securityManager 然后 securityManager 会注入自定义 Realm ,然后自定义Realm类里面会注入业务的service类,而那些service类包含事务,都是动态代理类。因此无法注入,大致异常为:xxxx is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)
解决方法:
import org.springframework.context.annotation.Lazy;
import org.apache.shiro.realm.AuthorizingRealm;
public class DatabaseRealm extends AuthorizingRealm {
@Lazy
@Autowired
private UserService userService;
import org.springframework.context.annotation.Lazy;
import org.apache.shiro.realm.AuthorizingRealm;
public class DatabaseRealm extends AuthorizingRealm {
private UserService userService;
public DatabaseRealm(@Lazy @Autowired UserService userService){
this.userService = userService;
}
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;
**MUserService userService = SpringUtil.getBean(MUserService.class);**
MUser user = userService.getOneUser(userToken.getUsername());
if(user == null){
throw new UnknownAccountException("账户不存在");
}
return new SimpleAuthenticationInfo(user,user.getPassword(),getName());
}
由于shiro的bean先于Spring事务将userService实例化了,结果导致spring事务初始化时好无法扫描到该bean,导致这个bean上没有绑定事务,导致事务无效,报错如下:
import org.springframework.context.annotation.Lazy;
import org.apache.shiro.realm.AuthorizingRealm;
public class DatabaseRealm extends AuthorizingRealm {
@Lazy
@Autowired
private UserService userService;
public class UserRealm extends AuthorizingRealm {
@Autowired
private SysUserMapper sysUserMapper;
@Autowired
private SysPermissionMapper sysPermissionMapper;
}
