一、前言
本文小編將基于 SpringBoot 集成 Shiro 實(shí)現(xiàn)動(dòng)態(tài)uri權(quán)限隧膏，由前端vue在頁(yè)面配置uri哗讥，Java后端動(dòng)態(tài)刷新權(quán)限，不用重啟項(xiàng)目私植，以及在頁(yè)面分配給用戶 角色 忌栅、 按鈕 、uri 權(quán)限后，后端動(dòng)態(tài)分配權(quán)限索绪，用戶無(wú)需在頁(yè)面重新登錄才能獲取最新權(quán)限湖员，一切權(quán)限動(dòng)態(tài)加載，靈活配置
基本環(huán)境
- spring-boot 2.1.7
- mybatis-plus 2.1.0
- mysql 5.7.24
- redis 5.0.5
溫馨小提示：案例demo源碼附文章末尾瑞驱，有需要的小伙伴們可參考哦 ~

三、shiro動(dòng)態(tài)加載權(quán)限處理方法
-
loadFilterChainDefinitionMap：初始化權(quán)限
ex: 在上面Shiro配置類ShiroConfig中的Shiro基礎(chǔ)配置shiroFilterFactory方法中我們就需要調(diào)用此方法將數(shù)據(jù)庫(kù)中配置的所有uri權(quán)限全部加載進(jìn)去岩梳，以及放行接口和配置權(quán)限過(guò)濾器等
【注：過(guò)濾器配置順序不能顛倒囊骤，多個(gè)過(guò)濾器用,分割】
ex:filterChainDefinitionMap.put("/api/system/user/list", "authc,token,zqPerms[user1]") -
updatePermission：動(dòng)態(tài)刷新加載數(shù)據(jù)庫(kù)中的uri權(quán)限 -> 頁(yè)面在新增uri路徑到數(shù)據(jù)庫(kù)中，也就是配置新的權(quán)限時(shí)就可以調(diào)用此方法實(shí)現(xiàn)動(dòng)態(tài)加載uri權(quán)限 -
updatePermissionByRoleId：shiro動(dòng)態(tài)權(quán)限加載 -> 即分配指定用戶權(quán)限時(shí)可調(diào)用此方法刪除shiro緩存蒋腮，重新執(zhí)行doGetAuthorizationInfo方法授權(quán)角色和權(quán)限
public interface ShiroService {
/**

四、shiro中自定義角色竭讳、權(quán)限過(guò)濾器
1创葡、自定義uri權(quán)限過(guò)濾器 zqPerms
@Slf4j
public class MyPermissionsAuthorizationFilter extends PermissionsAuthorizationFilter {
@Override
protected boolean onAccessDenied(ServletRequest request, ServletResponse response, Object mappedValue) throws Exception {
HttpServletRequest httpRequest = (HttpServletRequest) request;
HttpServletResponse httpResponse = (HttpServletResponse) response;
String requestUrl = httpRequest.getServletPath();
log.info("請(qǐng)求的url: " + requestUrl);
// 檢查是否擁有訪問(wèn)權(quán)限
Subject subject = this.getSubject(request, response);
if (subject.getPrincipal() == null) {
this.saveRequestAndRedirectToLogin(request, response);
} else {
// 轉(zhuǎn)換成http的請(qǐng)求和響應(yīng)
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse resp = (HttpServletResponse) response;
// 獲取請(qǐng)求頭的值
String header = req.getHeader("X-Requested-With");
// ajax 的請(qǐng)求頭里有X-Requested-With: XMLHttpRequest 正常請(qǐng)求沒(méi)有
if (header!=null && "XMLHttpRequest".equals(header)){
resp.setContentType("text/json,charset=UTF-8");
resp.getWriter().print("{\"success\":false,\"msg\":\"沒(méi)有權(quán)限操作！\"}");
}else { //正常請(qǐng)求
String unauthorizedUrl = this.getUnauthorizedUrl();
if (StringUtils.hasText(unauthorizedUrl)) {
WebUtils.issueRedirect(request, response, unauthorizedUrl);
} else {
WebUtils.toHttp(response).sendError(401);
}
}
}
return false;
}
}
2绢慢、自定義角色權(quán)限過(guò)濾器 zqRoles
shiro原生的角色過(guò)濾器RolesAuthorizationFilter 默認(rèn)是必須同時(shí)滿足roles[admin,guest]才有權(quán)限灿渴，而自定義的zqRoles 只滿足其中一個(gè)即可訪問(wèn)
ex: zqRoles[admin,guest]
public class MyRolesAuthorizationFilter extends AuthorizationFilter {
@Override
protected boolean isAccessAllowed(ServletRequest req, ServletResponse resp, Object mappedValue) throws Exception {
Subject subject = getSubject(req, resp);
String[] rolesArray = (String[]) mappedValue;
// 沒(méi)有角色限制，有權(quán)限訪問(wèn)
if (rolesArray == null || rolesArray.length == 0) {
return true;
}
for (int i = 0; i < rolesArray.length; i++) {
//若當(dāng)前用戶是rolesArray中的任何一個(gè)，則有權(quán)限訪問(wèn)
if (subject.hasRole(rolesArray[i])) {
return true;
}
}
return false;
}
}
3骚露、自定義token過(guò)濾器 token -> 判斷token是否過(guò)期失效等
@Slf4j
public class TokenCheckFilter extends UserFilter {
/**
* token過(guò)期蹬挤、失效
*/
private static final String TOKEN_EXPIRED_URL = "/api/auth/tokenExpired";
/**
* 判斷是否擁有權(quán)限 true:認(rèn)證成功 false:認(rèn)證失敗
* mappedValue 訪問(wèn)該url時(shí)需要的權(quán)限
* subject.isPermitted 判斷訪問(wèn)的用戶是否擁有mappedValue權(quán)限
*/
@Override
public boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) {
HttpServletRequest httpRequest = (HttpServletRequest) request;
HttpServletResponse httpResponse = (HttpServletResponse) response;
// 根據(jù)請(qǐng)求頭拿到token
String token = WebUtils.toHttp(request).getHeader(Constants.REQUEST_HEADER);
log.info("瀏覽器token：" + token );
User userInfo = ShiroUtils.getUserInfo();
String userToken = userInfo.getToken();
// 檢查token是否過(guò)期
if ( !token.equals(userToken) ){
return false;
}
return true;
}
/**
* 認(rèn)證失敗回調(diào)的方法: 如果登錄實(shí)體為null就保存請(qǐng)求和跳轉(zhuǎn)登錄頁(yè)面,否則就跳轉(zhuǎn)無(wú)權(quán)限配置頁(yè)面
*/
@Override
protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws IOException {
User userInfo = ShiroUtils.getUserInfo();
// 重定向錯(cuò)誤提示處理 - 前后端分離情況下
WebUtils.issueRedirect(request, response, TOKEN_EXPIRED_URL);
return false;
}
}

2蹋嵌、Redis常量類
public interface RedisConstant {
/**
* TOKEN前綴
*/
String REDIS_PREFIX_LOGIN = "code-generator_token_%s";
}
3育瓜、Spring上下文工具類
@Component
public class SpringUtil implements ApplicationContextAware {
private static ApplicationContext context;
/**
* Spring在bean初始化后會(huì)判斷是不是ApplicationContextAware的子類
* 如果該類是,setApplicationContext()方法,會(huì)將容器中ApplicationContext作為參數(shù)傳入進(jìn)去
*/
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
context = applicationContext;
}
/**
* 通過(guò)Name返回指定的Bean
*/
public static <T> T getBean(Class<T> beanClass) {
return context.getBean(beanClass);
}
}
