一、Shiro简介

1、基础概念

Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码和会话管理。作为一款安全框架Shiro的设计相当巧妙。Shiro的应用不依赖任何容器，它不仅可以在JavaEE下使用，还可以应用在JavaSE环境中。

2、核心角色

1）Subject：认证主体

代表当前系统的使用者，就是用户，在Shiro的认证中，认证主体通常就是userName和passWord，或者其他用户相关的唯一标识。

2）SecurityManager：安全管理器

Shiro架构中最核心的组件，通过它可以协调其他组件完成用户认证和授权。实际上，SecurityManager就是Shiro框架的控制器。

3）Realm：域对象

定义了访问数据的方式，用来连接不同的数据源，如：关系数据库，配置文件等等。

3、核心理念
Shiro自己不维护用户和权限，通过Subject用户主体和Realm域对象的注入，完成用户的认证和授权。

二、整合SpringBoot2框架

1、核心依赖


  org.apache.shiro
  shiro-core
  1.4.0


  org.apache.shiro
  shiro-spring
  1.4.0

2、Shiro核心配置

@Configuration
public class ShiroConfig {
  
  @Bean("sessionManager")
  public SessionManager sessionManager(){
    DefaultWebSessionManager sessionManager = new DefaultWebSessionManager();
    //设置session过期时间
    sessionManager.setGlobalSessionTimeout(60 * 60 * 1000);
    sessionManager.setSessionValidationSchedulerEnabled(true);
    // 去掉shiro登录时url里的JSESSIonID
    sessionManager.setSessionIdUrlRewritingEnabled(false);
    return sessionManager;
  }

  
  @Bean("securityManager")
  public SecurityManager securityManager(UserRealm userRealm, SessionManager sessionManager) {
    DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
    securityManager.setSessionManager(sessionManager);
    securityManager.setRealm(userRealm);
    return securityManager;
  }
  
  @Bean("shiroFilter")
  public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager) {
    ShiroFilterFactoryBean shiroFilter = new ShiroFilterFactoryBean();
    shiroFilter.setSecurityManager(securityManager);
    shiroFilter.setLoginUrl("/userLogin");
    shiroFilter.setUnauthorizedUrl("/");
    Map filterMap = new linkedHashMap<>();
    filterMap.put("/userLogin", "anon");
    shiroFilter.setFilterChainDefinitionMap(filterMap);
    return shiroFilter;
  }
  
  @Bean("lifecycleBeanPostProcessor")
  public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
    return new LifecycleBeanPostProcessor();
  }
  
  @Bean
  public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
    DefaultAdvisorAutoProxyCreator proxyCreator = new DefaultAdvisorAutoProxyCreator();
    proxyCreator.setProxyTargetClass(true);
    return proxyCreator;
  }
  
  @Bean
  public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
    AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor();
    advisor.setSecurityManager(securityManager);
    return advisor;
  }
}

3、域对象配置

@Component
public class UserRealm extends AuthorizingRealm {
  @Resource
  private SysUserMapper sysUserMapper ;
  @Resource
  private SysMenuMapper sysMenuMapper ;
  
  @Override
  public AuthorizationInfo doGetAuthorizationInfo
  (PrincipalCollection principals) {
    SysUserEntity user = (SysUserEntity)principals.getPrimaryPrincipal();
    if(user == null) {
      throw new UnknownAccountException("账号不存在");
    }
    List permsList;
    //默认用户拥有最高权限
    List menuList = sysMenuMapper.selectList();
    permsList = new ArrayList<>(menuList.size());
    for(SysMenuEntity menu : menuList){
      permsList.add(menu.getPerms());
    }
    //用户权限列表
    Set permsSet = new HashSet<>();
    for(String perms : permsList){
      if(StringUtils.isEmpty(perms)){
 continue;
      }
      permsSet.addAll(Arrays.asList(perms.trim().split(",")));
    }
    SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
    info.setStringPermissions(permsSet);
    return info;
  }
  
  @Override
  protected AuthenticationInfo doGetAuthenticationInfo(
      AuthenticationToken authToken) throws AuthenticationException {
    UsernamePasswordToken token = (UsernamePasswordToken)authToken;
    //查询用户信息
    SysUserEntity user = sysUserMapper.selectOne(token.getUsername());
    //账号不存在
    if(user == null) {
      throw new UnknownAccountException("账号或密码不正确");
    }
    //账号锁定
    if(user.getStatus() == 0){
      throw new LockedAccountException("账号已被锁定,请联系管理员");
    }
    SimpleAuthenticationInfo info = new SimpleAuthenticationInfo
 (user, user.getPassword(),
     ByteSource.Util.bytes(user.getSalt()),
     getName());
    return info;
  }
  @Override
  public void setCredentialsMatcher(CredentialsMatcher credentialsMatcher) {
    HashedCredentialsMatcher shaCredentialsMatcher = new HashedCredentialsMatcher();
    shaCredentialsMatcher.setHashAlgorithmName(ShiroUtils.hashAlgorithmName);
    shaCredentialsMatcher.setHashIterations(ShiroUtils.hashIterations);
    super.setCredentialsMatcher(shaCredentialsMatcher);
  }
}

4、核心工具类

public class ShiroUtils {
  
  public final static String hashAlgorithmName = "SHA-256";
  
  public final static int hashIterations = 16;
  public static String sha256(String password, String salt) {
    return new SimpleHash(hashAlgorithmName, password, salt, hashIterations).toString();
  }
  // 获取一个测试账号 admin
  public static void main(String[] args) {
    // 3743a4c09a17e6f2829febd09ca54e627810001cf255ddcae9dabd288a949c4a
    System.out.println(sha256("admin","123")) ;
  }
  
  public static Session getSession() {
    return SecurityUtils.getSubject().getSession();
  }
  
  public static Subject getSubject() {
    return SecurityUtils.getSubject();
  }
  public static SysUserEntity getUserEntity() {
    return (SysUserEntity)SecurityUtils.getSubject().getPrincipal();
  }
  public static Long getUserId() {
    return getUserEntity().getUserId();
  }
  public static void setSessionAttribute(Object key, Object value) {
    getSession().setAttribute(key, value);
  }
  public static Object getSessionAttribute(Object key) {
    return getSession().getAttribute(key);
  }
  public static boolean isLogin() {
    return SecurityUtils.getSubject().getPrincipal() != null;
  }
  public static void logout() {
    SecurityUtils.getSubject().logout();
  }
}
5、自定义权限异常提示
@RestControllerAdvice
public class ShiroException {
  @ExceptionHandler(AuthorizationException.class)
  public String authorizationException (){
    return "抱歉您没有权限访问该内容!";
  }
  @ExceptionHandler(Exception.class)
  public String handleException(Exception e){
    return "系统异常!";
  }
}

三、案例演示代码

1、测试接口

@RestController
public class ShiroController {
  private static Logger LOGGER = LoggerFactory.getLogger(ShiroController.class) ;
  @Resource
  private SysMenuMapper sysMenuMapper ;
  
  @RequestMapping("/userLogin")
  public void userLogin (
      @RequestParam(value = "userName") String userName,
      @RequestParam(value = "passWord") String passWord){
    try{
      Subject subject = ShiroUtils.getSubject();
      UsernamePasswordToken token = new UsernamePasswordToken(userName, passWord);
      subject.login(token);
      LOGGER.info("登录成功");
    }catch (Exception e) {
      e.printStackTrace();
    }
  }
  
  @RequestMapping("/menu/list")
  @RequiresPermissions("sys:user:shiro")
  public List list(){
    return sysMenuMapper.selectList() ;
  }
  
  @RequestMapping("/menu/list2")
  @RequiresPermissions("ccc:ddd:bbb")
  public List list2(){
    return sysMenuMapper.selectList() ;
  }
  
  @RequestMapping("/userLogOut")
  public String logout (){
    ShiroUtils.logout();
    return "success" ;
  }
}

2、测试流程

1)、登录后取得权限
http://localhost:7011/userLogin?userName=admin&passWord=admin
2)、访问有权限接口
http://localhost:7011/menu/list
3)、访问无权限接口
http://localhost:7011/menu/list2
4)、退出登录
http://localhost:7011/userLogOut
