  • SpringBoot中用shiro做单点登录

    实际项目中用shiro做权限与登录验证，并做单点登录，单点登录克服有浏览器cookie的sessionID的统一与redis缓存的sessionID统一  也就是所有的sessionID要一致。

    怕忘记并记录下，实际项目redis采用集群。

    DefaultWebSessionManager类    介绍  不是项目用到的

    DefaultWebSessionManager类
1.数据属性

private Cookie sessionIdCookie;//sessionId cookie
private boolean sessionIdCookieEnabled;//session是否可以被保存到cookie中

2.构造方法

public DefaultWebSessionManager() {
        Cookie cookie = new SimpleCookie(ShiroHttpSession.DEFAULT_SESSION_ID_NAME);
        cookie.setHttpOnly(true); //more secure, protects against XSS attacks
        this.sessionIdCookie = cookie;
        this.sessionIdCookieEnabled = true;
}

3.获取sessionIdCookie

public Cookie getSessionIdCookie() {
        return sessionIdCookie;
}

4.设置sessionIdCookie

public void setSessionIdCookie(Cookie sessionIdCookie) {
        this.sessionIdCookie = sessionIdCookie;
}

5.是否将sessionId存储到cookie中

public boolean isSessionIdCookieEnabled() {
        return sessionIdCookieEnabled;
}

6.设置是否将sessionId存储到cookie中

public void setSessionIdCookieEnabled(boolean sessionIdCookieEnabled) {
        this.sessionIdCookieEnabled = sessionIdCookieEnabled;
}

7.存储sessionId到cookie中

private void storeSessionId(Serializable currentId, HttpServletRequest request, HttpServletResponse response) {
        if (currentId == null) {
            String msg = "sessionId cannot be null when persisting for subsequent requests.";
            throw new IllegalArgumentException(msg);
        }
        Cookie template = getSessionIdCookie();
        Cookie cookie = new SimpleCookie(template);
        String idString = currentId.toString();
        cookie.setValue(idString);
        cookie.saveTo(request, response);
        log.trace("Set session ID cookie for session with id {}", idString);
    }

8.从cookie中移除session信息

private void removeSessionIdCookie(HttpServletRequest request, HttpServletResponse response) {
        getSessionIdCookie().removeFrom(request, response);
}

9.从cookie中读取sessionId信息

private String getSessionIdCookieValue(ServletRequest request, ServletResponse response) {
        if (!isSessionIdCookieEnabled()) {
            log.debug("Session ID cookie is disabled - session id will not be acquired from a request cookie.");
            return null;
        }
        if (!(request instanceof HttpServletRequest)) {
            log.debug("Current request is not an HttpServletRequest - cannot get session ID cookie.  Returning null.");
            return null;
        }
        HttpServletRequest httpRequest = (HttpServletRequest) request;
        return getSessionIdCookie().readValue(httpRequest, WebUtils.toHttp(response));
    }

10.检测sessionId关联源(如果可以从cookie中获取sessionId,则在request中设置sessionId的关联源为cookie；如果不可以读取，则从request访问路径中获取，如果不存在，则从request的parameter中获取，如果从request的访问路径中或者parameter中获取到的不为空，则设置关联源为url；并在将sessionId和合法信息存储到request中)

private Serializable getReferencedSessionId(ServletRequest request, ServletResponse response) {

        String id = getSessionIdCookieValue(request, response);
        if (id != null) {
            request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE,
                    ShiroHttpServletRequest.COOKIE_SESSION_ID_SOURCE);
        } else {
            //not in a cookie, or cookie is disabled - try the request URI as a fallback (i.e. due to URL rewriting):

            //try the URI path segment parameters first:
            id = getUriPathSegmentParamValue(request, ShiroHttpSession.DEFAULT_SESSION_ID_NAME);

            if (id == null) {
                //not a URI path segment parameter, try the query parameters:
                String name = getSessionIdName();
                id = request.getParameter(name);
                if (id == null) {
                    //try lowercase:
                    id = request.getParameter(name.toLowerCase());
                }
            }
            if (id != null) {
                request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE,
                        ShiroHttpServletRequest.URL_SESSION_ID_SOURCE);
            }
        }
        if (id != null) {
            request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, id);
            //automatically mark it valid here.  If it is invalid, the
            //onUnknownSession method below will be invoked and we'll remove the attribute at that time.
            request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE);
        }
        return id;
    }

11.从request路径中获取sessionId信息

private String getUriPathSegmentParamValue(ServletRequest servletRequest, String paramName) {

        if (!(servletRequest instanceof HttpServletRequest)) {
            return null;
        }
        HttpServletRequest request = (HttpServletRequest)servletRequest;
        String uri = request.getRequestURI();
        if (uri == null) {
            return null;
        }

        int queryStartIndex = uri.indexOf('?');
        if (queryStartIndex >= 0) { //get rid of the query string
            uri = uri.substring(0, queryStartIndex);
        }

        int index = uri.indexOf(';'); //now check for path segment parameters:
        if (index < 0) {
            //no path segment params - return:
            return null;
        }

        //there are path segment params, let's get the last one that may exist:

        final String TOKEN = paramName + "=";

        uri = uri.substring(index+1); //uri now contains only the path segment params

        //we only care about the last JSESSIONID param:
        index = uri.lastIndexOf(TOKEN);
        if (index < 0) {
            //no segment param:
            return null;
        }

        uri = uri.substring(index + TOKEN.length());

        index = uri.indexOf(';'); //strip off any remaining segment params:
        if(index >= 0) {
            uri = uri.substring(0, index);
        }

        return uri; //what remains is the value
    }

12.获取sessionId名字

private String getSessionIdName() {
        String name = this.sessionIdCookie != null ? this.sessionIdCookie.getName() : null;
        if (name == null) {
            name = ShiroHttpSession.DEFAULT_SESSION_ID_NAME;
        }
        return name;
    }

13.创建session信息(它覆盖了AbstractNativeSessionManager接口的方法)

protected Session createExposedSession(Session session, SessionContext context) {
        if (!WebUtils.isWeb(context)) {
            return super.createExposedSession(session, context);
        }
        ServletRequest request = WebUtils.getRequest(context);
        ServletResponse response = WebUtils.getResponse(context);
        SessionKey key = new WebSessionKey(session.getId(), request, response);
        return new DelegatingSession(this, key);
    }

14.创建session信息(它覆盖了AbstractNativeSessionManager抽象类的方法)

protected Session createExposedSession(Session session, SessionKey key) {
        if (!WebUtils.isWeb(key)) {
            return super.createExposedSession(session, key);
        }

        ServletRequest request = WebUtils.getRequest(key);
        ServletResponse response = WebUtils.getResponse(key);
        SessionKey sessionKey = new WebSessionKey(session.getId(), request, response);
        return new DelegatingSession(this, sessionKey);
    }

15.启动session(将session存储到cookie中，并将cookie中移除session源，设置session是新的，它覆盖了AbstractNativeSessionManager抽象类的方法)

protected void onStart(Session session, SessionContext context) {
        super.onStart(session, context);

        if (!WebUtils.isHttp(context)) {
            log.debug("SessionContext argument is not HTTP compatible or does not have an HTTP request/response " +
                    "pair. No session ID cookie will be set.");
            return;

        }
        HttpServletRequest request = WebUtils.getHttpRequest(context);
        HttpServletResponse response = WebUtils.getHttpResponse(context);

        if (isSessionIdCookieEnabled()) {
            Serializable sessionId = session.getId();
            storeSessionId(sessionId, request, response);
        } else {
            log.debug("Session ID cookie is disabled.  No cookie has been set for new session with id {}", session.getId());
        }

        request.removeAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE);
        request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_IS_NEW, Boolean.TRUE);
    }

16.获取sessionId(先从sessionKey中获取，如果没有，则从cookie中获取，如果在没有，则从request请求路径或者parameter中获取，它覆盖了DefaultSessionManager类的方法)

public Serializable getSessionId(SessionKey key) {
        Serializable id = super.getSessionId(key);
        if (id == null && WebUtils.isWeb(key)) {
            ServletRequest request = WebUtils.getRequest(key);
            ServletResponse response = WebUtils.getResponse(key);
            id = getSessionId(request, response);
        }
        return id;
    }

17.从cookie或者request中获取sessionId信息

protected Serializable getSessionId(ServletRequest request, ServletResponse response) {
        return getReferencedSessionId(request, response);
}

18.session过期(它覆盖了AbstractValidatingSessionManager抽象类的方法)

protected void onExpiration(Session s, ExpiredSessionException ese, SessionKey key) {
        super.onExpiration(s, ese, key);
        onInvalidation(key);
}

19.session失效(它覆盖了AbstractValidatingSessionManager抽象类的方法)

protected void onInvalidation(Session session, InvalidSessionException ise, SessionKey key) {
        super.onInvalidation(session, ise, key);
        onInvalidation(key);
    }

20.移除request中属性(sessionId是合法的和从cookie中移除sessionId)

private void onInvalidation(SessionKey key) {
        ServletRequest request = WebUtils.getRequest(key);
        if (request != null) {
            request.removeAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID);
        }
        if (WebUtils.isHttp(key)) {
            log.debug("Referenced session was invalid.  Removing session ID cookie.");
            removeSessionIdCookie(WebUtils.getHttpRequest(key), WebUtils.getHttpResponse(key));
        } else {
            log.debug("SessionKey argument is not HTTP compatible or does not have an HTTP request/response " +
                    "pair. Session ID cookie will not be removed due to invalidated session.");
        }
    }
21.暂停session(设置session的暂停时间，并从cookie中移除session，它实现了AbstractNativeSessionManager抽象类的方法)

protected void onStop(Session session, SessionKey key) {
        super.onStop(session, key);
        if (WebUtils.isHttp(key)) {
            HttpServletRequest request = WebUtils.getHttpRequest(key);
            HttpServletResponse response = WebUtils.getHttpResponse(key);
            log.debug("Session has been stopped (subject logout or explicit stop).  Removing session ID cookie.");
            removeSessionIdCookie(request, response);
        } else {
            log.debug("SessionKey argument is not HTTP compatible or does not have an HTTP request/response " +
                    "pair. Session ID cookie will not be removed due to stopped session.");
        }
    }

22.如果session被servlet container管理则返回true；如果被shiro管理，则返回false

public boolean isServletContainerSessions() {
        return false;
}

    二、登录，验证，并且双身份用户Realm （服务端）  ChildrenRealm是普通用户登录，UserRealm系统管理员用户登录   所以这个设计是有两个登录页面

    1、LoginController

    package com.sso.system.controller;

import com.sso.common.annotation.Log;
import com.sso.common.controller.BaseController;
import com.sso.common.domain.FileDO;

import org.apache.shiro.subject.Subject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;

@Controller
public class LoginController extends BaseController {
    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Autowired
    MenuService menuService;
    @Autowired
    FileService fileService;
    @GetMapping({ "/", "" })
    String welcome(Model model) {

        return "redirect:/login";
    }

    @Log("请求访问主页")
    @GetMapping({ "/index" })
    String index(Model model) {
        List<Tree<MenuDO>> menus = menuService.listMenuTree(getUserId());
        model.addAttribute("menus", menus);
        model.addAttribute("name", getUser().getName());
        FileDO fileDO = fileService.get(getUser().getPicId());
        if(fileDO!=null&&fileDO.getUrl()!=null){
            if(fileService.isExist(fileDO.getUrl())){
                model.addAttribute("picUrl",fileDO.getUrl());

        return "index_v1";
    }

    @GetMapping("/login")
    String login() {
        return "login";
    }

    @Log("登录")
    @PostMapping("/login")
    @ResponseBody
    R ajaxLogin(String username, String password) {

        password = MD5Utils.encrypt(username, password);
        UserToken token = new UserToken(username, password,"User");
        Subject subject = SecurityUtils.getSubject();
        try {
            subject.login(token);
            return R.ok();
        }catch (UnknownAccountException e) {

        }catch (IncorrectCredentialsException e) {
            return R.error("密码错误");
        }
    }

    @GetMapping("/logout")
    String logout() {
        ShiroUtils.logout();
        return "redirect:/login";
    }

    @GetMapping("/main")
    String main() {
        return "main";
    }

}

    2、ChildrenRealm  这个是客户登录   Realm提供了安全的访问应用的相关实体类，比如用户、角色、权限，对其中的访问应用相应的认证或者授权操作。其提供的主要的方法为AuthenticationInfo#getAuthenticationInfo，涉及的内容是关于信息的认证，这主要由AuthencatingRealm类实现

    package com.sso.system.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;

@Controller
public class LoginController extends BaseController {
    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Autowired
    MenuService menuService;
    @Autowired
    FileService fileService;
    @GetMapping({ "/", "" })
    String welcome(Model model) {

        return "redirect:/login";
    }

    @Log("请求访问主页")
    @GetMapping({ "/index" })
    String index(Model model) {
        List<Tree<MenuDO>> menus = menuService.listMenuTree(getUserId());
        model.addAttribute("menus", menus);
        model.addAttribute("name", getUser().getName());
        FileDO fileDO = fileService.get(getUser().getPicId());
        if(fileDO!=null&&fileDO.getUrl()!=null){
            if(fileService.isExist(fileDO.getUrl())){
                model.addAttribute("picUrl",fileDO.getUrl());
            }else {
                model.addAttribute("picUrl","/img/photo_s.jpg");
            }
        }else {
            model.addAttribute("picUrl","/img/photo_s.jpg");
        }
        model.addAttribute("username", getUser().getUsername());
        return "index_v1";
    }

    @GetMapping("/login")
    String login() {
        return "login";
    }

    @Log("登录")
    @PostMapping("/login")
    @ResponseBody
    R ajaxLogin(String username, String password) {

        password = MD5Utils.encrypt(username, password);
        UserToken token = new UserToken(username, password,"User");
        Subject subject = SecurityUtils.getSubject();

        }catch (IncorrectCredentialsException e) {
            return R.error("密码错误");
        }
    }

    @GetMapping("/logout")
    String logout() {
        ShiroUtils.logout();
        return "redirect:/login";
    }

    @GetMapping("/main")
    String main() {
        return "main";
    }

}

        Long userId = ShiroUtils.getUserId();
        MenuService menuService = ApplicationContextRegister.getBean(MenuService.class);
        Set<String> perms = menuService.listPerms(userId);
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();

        String username = (String) token.getPrincipal();
        Map<String, Object> map = new HashMap<>(16);
        map.put("username", username);
        String password = new String((char[]) token.getCredentials());

        UserDao userMapper = ApplicationContextRegister.getBean(UserDao.class);
        // 查询用户信息
        List<UserDO> userDOS = userMapper.list(map);
        UserDO user = null;
        if(userDOS.size()>0){
            user=userDOS.get(0);
        }

        // 账号不存在
        if (user == null) {
            throw new UnknownAccountException("账号或密码不正确");
        }

        // 密码错误
        if (!password.equals(user.getPassword())) {
