Shiro综述
graph LRA1("CacheManager")-->BA2("Realms")-->BA3("UserDao")-->CA4("CredentialsMatcher")-->CA1-->Csubgraph ShiroA("Subject(用户)")-->B("SecurityManager(安全管理器)")B-->C("Realm域")end
- Subject：主体，代表了当前 “用户”
- SecurityManager：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；是 Shiro 的核心
- Realm：域，Shiro 从从 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。
//获取用户,其会自动绑定到当前线程
Subject subject = SecurityUtils.getSubject();
//构建待认证token
UsernamePasswordToken token = new UsernamePasswordToken("zhang", "123");
//登录，即身份验证
subject.login(token);
//判断是否已经认证
subject.isAuthenticated()
//登出
subject.logout(token);

过滤器
认证拦截器
- anon 匿名拦截器，不需要认证即可访问，如 /static/**=anon，/login=anon
- authc 需要认证才可以访问，如/**=authc
- user 用户已经身份验证 / 记住我登录的都可；示例 /**=user
- logout 退出拦截器,如 /logout=logout
授权拦截器
- roles 角色授权拦截器，验证用户是否拥有角色；如：/admin/**=roles[admin]
- perms 权限授权拦截器，验证用户是否拥有所有权限；/user/**=perms["user:create"]
注解
- @RequiresPermissions 验证权限
- @RequiresRoles 验证角色
- @RequiresUser 验证用户是否登录（包含通过记住我登录的）
- @RequiresAuthentication 验证是否已认证（不含通过记住我登录的）
- @RequiresGuest 不需要认证即可访问
//拥有ADMIN角色同时还要有sys:role:info权限
@RequiresRoles(value={"ADMIN")
@RequiresPermissions("sys:role:info")
整合Shiro
1. 配置SecurityManager
@Bean("securityManager")
public org.apache.shiro.mgt.SecurityManager securityManager(ShrioRealm shrioRealm, PhoneRealm phoneRealm) {
DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
// //注入自定义myRealm
// defaultWebSecurityManager.setRealm(shrioRealm);
//设置多个realm,用户名密码登录realm,手机号短信验证码登录realm
List<Realm> realms = new ArrayList<>();
realms.add(shrioRealm);
realms.add(phoneRealm);
defaultWebSecurityManager.setRealms(realms);
return defaultWebSecurityManager;
}
2.实现Realm
/**
*
* 自定义realm
* @author yuxf
* @version 1.0
* @date 2020/12/21 16:10
*/
public class ShrioRealm extends AuthorizingRealm {
@Autowired
TestShiroUserService userService;
/**
* 获取授权信息
* @param principals
* @return
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
//从数据库取角色
Set<String> roles = userService.getRoles();
SimpleAuthorizationInfo simpleAuthorizationInfo=new SimpleAuthorizationInfo();//权限信息
simpleAuthorizationInfo.addRoles(roles);
simpleAuthorizationInfo.addStringPermission("user:create");
return simpleAuthorizationInfo;
}
/**
* 获取认证信息
* @param token
* @return
* @throws AuthenticationException
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
if(token.getPrincipal()==null)return null;
String userName=token.getPrincipal().toString();
//从数据库查询用户名
String dbUser = userService.loadUserByUserName(userName);
if(dbUser==null||"".equals(dbUser)) throw new UnknownAccountException();
//密码盐
ByteSource salt = ByteSource.Util.bytes(userName);
SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(userName, "123456", salt,getName());
return simpleAuthenticationInfo;
}
}
@Bean
public ShrioRealm shrioRealm() {
ShrioRealm shrioRealm = new ShrioRealm();
//设置密码加密规则
shrioRealm.setCredentialsMatcher(hashedCredentialsMatcher());
return shrioRealm;
}
/**
* 凭证匹配器
*
* @return
*/
@Bean
public HashedCredentialsMatcher hashedCredentialsMatcher() {
HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
hashedCredentialsMatcher.setHashAlgorithmName("md5");//散列算法:这里使用MD5算法;
hashedCredentialsMatcher.setHashIterations(2);//散列的次数，比如散列两次，相当于 md5(md5(""));
return hashedCredentialsMatcher;
}
/**
* 注册时需要生成密码和密码盐存入数据库
* @author yuxf
* @version 1.0
* @date 2020/12/22 17:01
*/
public class PasswordHelper {
private static String algorithmName = "md5";
private static final int hashIterations = 2;
/**
* 获取随机密码盐
* @return
*/
public static String getSalt()
{
RandomNumberGenerator randomNumberGenerator = new SecureRandomNumberGenerator();
String salt = randomNumberGenerator.nextBytes().toHex();
return salt;
}
/**
* 生成密码
* @param plainPassword 明文密码
* @param salt 密码盐
* @return
*/
public static String getPassowrd(String plainPassword,String salt)
{
String newPassword = new SimpleHash(algorithmName, plainPassword, salt, hashIterations).toHex();
return newPassword;
}
}
3.配置LifecycleBeanPostProcessor
/**
* 配置LifecycleBeanPostProcessor 可以自动调用配置在Spring IOC容器中 Shiro Bean的生命周期方法
* @return
*/
@Bean
public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
return new LifecycleBeanPostProcessor();
}
4.启动注解
/**
* 配置注解生效
*
* @return
*/
@Bean
public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
defaultAdvisorAutoProxyCreator.setProxyTargetClass(true);
return defaultAdvisorAutoProxyCreator;
}
/**
* 配置注解生效
*
* @return
*/
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(@Qualifier("securityManager") org.apache.shiro.mgt.SecurityManager securityManager) {
AuthorizationAttributeSourceAdvisor sourceAdvisor = new AuthorizationAttributeSourceAdvisor();
sourceAdvisor.setSecurityManager(securityManager);
return sourceAdvisor;
}
5.配置ShiroFilter
@Bean("shiroFilterFactoryBean")
public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier("securityManager") org.apache.shiro.mgt.SecurityManager securityManager) {
//shiro对象
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
bean.setSecurityManager(securityManager);
bean.setLoginUrl("/shiro/login");
bean.setSuccessUrl("/shrio/index");
LinkedHashMap<String, String> linkedHashMap = new LinkedHashMap<String, String>();
//认证顺序是从上往下执行。
linkedHashMap.put("/logout", "logout");//在这儿配置登出地址，不需要专门去写控制器。
linkedHashMap.put("/shiro/phoneLogin", "anon");
linkedHashMap.put("/demo/**", "anon");
linkedHashMap.put("/static/**", "anon");
linkedHashMap.put("/shiro/anon", "anon");
linkedHashMap.put("/**", "user");//需要进行权限验证
bean.setFilterChainDefinitionMap(linkedHashMap);
return bean;
}
SSM项目中web.xml中配置shiroFilter
<!-- shiro过虑器，DelegatingFilterProxy通过代理模式将spring容器中的bean和filter关联起来 -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<!-- 设置true由servlet容器控制filter的生命周期 -->
<init-param>
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
<!-- 设置spring容器filter的bean id，如果不设置则找与filter-name一致的bean -->
<init-param>
<param-name>targetBeanName</param-name>
<param-value>shiro</param-value>
</init-param>
</filter>

加密
https://www.cnblogs.com/cac2020/p/13850318.html
1. 注入HashedCredentialsMatcher实现(推荐)
@Bean
public ShrioRealm shrioRealm() {
ShrioRealm shrioRealm = new ShrioRealm();
//设置密码加密规则
shrioRealm.setCredentialsMatcher(hashedCredentialsMatcher());
return shrioRealm;
}
/**
* 凭证匹配器
*
* @return
*/
@Bean
public HashedCredentialsMatcher hashedCredentialsMatcher() {
HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
hashedCredentialsMatcher.setHashAlgorithmName("md5");//散列算法:这里使用MD5算法;
hashedCredentialsMatcher.setHashIterations(2);//散列的次数，比如散列两次，相当于 md5(md5(""));
return hashedCredentialsMatcher;
}
加密帮助类
/**
* 注册时需要生成密码和密码盐存入数据库
*
* @author yuxf
* @version 1.0
* @date 2020/12/22 17:01
*/
public class PasswordHelper {
private static String algorithmName = "md5";
private static final int hashIterations = 2;
/**
* 获取随机密码盐
*
* @return
*/
public static String getSalt() {
RandomNumberGenerator randomNumberGenerator = new SecureRandomNumberGenerator();
String salt = randomNumberGenerator.nextBytes().toHex();
return salt;
}
/**
* 生成密码
*
* @param plainPassword 明文密码
* @param salt 密码盐
* @return
*/
public static String getPassowrd(String plainPassword, String salt) {
String newPassword = new SimpleHash(algorithmName, plainPassword, salt, hashIterations).toHex();
return newPassword;
}
}
2. 注入PasswordMatcher实现
@Bean
public PhoneRealm phoneRealm() {
PhoneRealm phoneRealm = new PhoneRealm();
//PasswordMatcher
PasswordMatcher passwordMatcher = new PasswordMatcher();
passwordMatcher.setPasswordService(passwordService());
phoneRealm.setCredentialsMatcher(passwordMatcher);
return phoneRealm;
}
@Bean
public PasswordService passwordService()
{
DefaultHashService hashService = new DefaultHashService();
hashService.setHashIterations(3);
hashService.setHashAlgorithmName("MD5");
hashService.setGeneratePublicSalt(true);
//设置HashService
DefaultPasswordService passwordService = new DefaultPasswordService();
passwordService.setHashService(hashService);
// passwordService.setHashFormat(new HexFormat());
return passwordService;
}
多身份Realm认证
- ()自定义AuthenticationToken并重写Realm的supports方法，来明确Real支持的Token
public class PhoneVcodeToken implements AuthenticationToken {
private String phone;
private String vcode;
public PhoneVcodeToken(String phone,String vcode)
{
this.phone=phone;
this.vcode=vcode;
}
@Override
public Object getPrincipal() {
return phone;
}
@Override
public Object getCredentials() {
return vcode;
}
}
Realm
public class PhoneRealm extends AuthorizingRealm {
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
return null;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
String userName = token.getPrincipal().toString();
if (userName.equals("admin")) {
//123456a
return new SimpleAuthenticationInfo(userName, "$shiro1$MD5$3$j8X4VX1f6T6zGiGEFIW5yA==$ipG89XmDquh++g5xXmV1dQ==", getName());
} else {
//123456
return new SimpleAuthenticationInfo(userName, "$shiro1$MD5$3$QvLJZY8JiAJMnK9vRjlG6w==$jbNS0N/3fq2KUXufYwGwWA==", getName());
}
}
@Override
public boolean supports(AuthenticationToken token) {
return token instanceof PhoneVcodeToken;
}
}
- 自定义AuthenticationToken并加入类型参数，重写ModularRealmAuthenticator 在doAuthenticate()方法中根据类型来选择Realm
/**
* @author chenzhi
* @Description: 自定义当使用多realm时管理器
* @Date:Created: in 13:41 2018/8/13
* @Modified by:
*/
public class MyModularRealmAuthenticator extends ModularRealmAuthenticator {
@Override
protected AuthenticationInfo doAuthenticate(AuthenticationToken authenticationToken) {
//先判断Realm是否为空
assertRealmsConfigured();
//强转为自定义的Token
MyUsernamePasswordToken myUsernamePasswordToken = (MyUsernamePasswordToken) authenticationToken;
//拿到登录类型
String loginType = myUsernamePasswordToken.getLoginType();
//拿到所有Realm集合
Collection<Realm> realms = getRealms();
List<Realm> myrealms = new ArrayList<>();
//遍历每个realm 根据loginType将对应的Reaml加入到myrealms
for (Realm realm : realms) {
//拿到Realm的类名 ，所以在定义Realm时，类名要唯一标识并且包含枚举中loginType某一个Type
//注意：一个Realm的类名不能包含有两个不同的loginType
if (realm.getName().contains(loginType)) {
myrealms.add(realm);
}
}
//判断是单Reaml还是多Realm
if (myrealms.size() == 1) {
return doSingleRealmAuthentication(myrealms.iterator().next(), myUsernamePasswordToken);
} else {
return doMultiRealmAuthentication(myrealms, myUsernamePasswordToken);
}
}
}
