本文是接着上篇博客寫的:Spring boot 入門(三):SpringBoot 集成結合 AdminLTE(Freemarker),利用 generate 自動生成代碼,利用 DataTable 和 PageHelper 進行分頁顯示。按照前面的博客,已經能夠搭建一個簡單的 Spring Boot 系統,本篇博客繼續對此係統進行改造,主要集成了 Shiro 權限認證框架,關於 Shiro 部分,在本人以前的博客(認證與Shiro安全框架)有介紹到,這裏就不作累贅的介紹。html
此係列的博客爲實踐部分,以代碼和搭建系統的過程爲主,如遇到專業名詞,自行查找其含義。前端
系統搭建到目前爲止,主要用到了3個配置類,均與 Shiro 有關,後期隨着項目的擴大,配置文件也會隨之增多。java
,若是不設置此變量,FreeMarker 頁面將不能識別 Shiro 的標籤
,其主要代碼以下:1 configuration.setSharedVariable("shiro", new ShiroTags());
在每次請求裏面都作了 session 的讀取和更新訪問時間等操做,這樣在集羣部署 session 共享的狀況下,數量級的加大了處理量負載
。本項目後期將用到分佈式,所以這裏就直接將過濾器與 Config 配置文件分離,提升效率。1 private final class MSpringShiroFilter extends AbstractShiroFilter { 2 protected MSpringShiroFilter(WebSecurityManager webSecurityManager, FilterChainResolver resolver) { 3 super(); 4 if (webSecurityManager == null) { 5 throw new IllegalArgumentException("WebSecurityManager property cannot be null."); 6 } 7 setSecurityManager(webSecurityManager); 8 if (resolver != null) { 9 setFilterChainResolver(resolver); 10 } 11 } 12 13 @Override 14 protected void doFilterInternal(ServletRequest servletRequest, ServletResponse servletResponse, 15 FilterChain chain) throws ServletException, IOException { 16 HttpServletRequest request = (HttpServletRequest) servletRequest; 17 String str = request.getRequestURI().toLowerCase(); 18 boolean flag = true; 19 int idx = 0; 20 if ((idx = str.indexOf(".")) > 0) { 21 str = str.substring(idx); 22 if (ignoreExt.contains(str.toLowerCase())) 23 flag = false; 24 } 25 if (flag) { 26 super.doFilterInternal(servletRequest, servletResponse, chain); 27 } else { 28 chain.doFilter(servletRequest, servletResponse); 29 } 30 } 31 32 }

主要重寫了 Realm域,完成權限認證和權限管理:web
1 protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { 2 //若是沒有作權限驗證,此處只須要return null便可 3 SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo(); 4 String userName = (String) principals.getPrimaryPrincipal(); 5 Result<TUser> list = userService.getUserByUsername(userName); 6 if(list.isStatus()) { 7 //獲取該用戶所屬的角色 8 Result<List<TRole>> resultRole = roleService.getRoleByUserId(list.getResultData().getUserId()); 9 if(resultRole.isStatus()) { 10 HashSet<String> role = new HashSet<String>(); 11 for(TRole tRole : resultRole.getResultData()) { 12 role.add(tRole.getRoleId()+""); 13 } 14 //獲取該角色擁有的權限 15 Result<List<TPermission>> resultPermission = permissionService.getPermissionsByRoleId(role); 16 if(resultPermission.isStatus()) { 17 HashSet<String> permissions = new HashSet<String>(); 18 for(TPermission tPermission : resultPermission.getResultData()) { 19 permissions.add(tPermission.getPermissionsValue()); 20 } 21 System.out.println("權限:"+permissions); 22 authorizationInfo.setStringPermissions(permissions); 23 } 24 } 25 } 26 //return null; 27 return authorizationInfo; 28 } 29 30 @Override 31 protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { 32 //認證登陸 33 String username = (String) authenticationToken.getPrincipal(); 34 //String password = new String((char[]) authenticationToken.getCredentials()); 35 Result<TUser> result = userService.getUserByUsername(username); 36 if (result.isStatus()) { 37 TUser user = result.getResultData(); 38 return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), getName()); 39 } 40 //return new SimpleAuthenticationInfo(user., "123456", getName()); 41 return null; 42 } 43 }
首先建立一個前端登陸界面,作一個簡單的登陸 Form 表單算法
點擊登陸即想後臺發送一個請求,必須是Post請求,不然Shiro不能識別
,認證部分主要在 Ream 中完成,新建一個類,繼承 AuthorizingRealm ,而後在重寫 doGetAuthenticationInfo 方法:數據庫
new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), getName())
),咱們能夠本身從新定義密碼比較器,密碼比較器的寫法較多,在認證與Shiro安全框架中,直接將密碼比較器寫入到Ream中,耦合度過高,本項目經過配置的方式重寫密碼比較器,具體代碼請參考參考ShiroConfiguration配置類:
1 @RequestMapping(value = "/login", method = RequestMethod.POST) 2 public String postLogin(RedirectAttributes redirectAttributes, HttpServletRequest request, HttpSession session) { 3 // 登陸失敗從request中獲取shiro處理的異常信息。 4 // shiroLoginFailure:就是shiro異常類的全類名. 5 String exception = (String) request.getAttribute("shiroLoginFailure"); 6 7 System.out.println("exception=" + exception); 8 String msg = ""; 9 if (exception != null) { 10 if (UnknownAccountException.class.getName().equals(exception)) { 11 System.out.println("UnknownAccountException -- > 帳號不存在:"); 12 msg = "用戶不存在!"; 13 } else if (IncorrectCredentialsException.class.getName().equals(exception)) { 14 System.out.println("IncorrectCredentialsException -- > 密碼不正確:"); 15 msg = "密碼不正確!"; 16 } else if ("kaptchaValidateFailed".equals(exception)) { 17 System.out.println("kaptchaValidateFailed -- > 驗證碼錯誤"); 18 msg = "驗證碼錯誤!"; 19 } else { 20 //msg = "else >> "+exception; 21 msg = "密碼不正確!"; 22 System.out.println("else -- >" + exception); 23 } 24 } 25 redirectAttributes.addFlashAttribute("msg", msg); 26 session.setAttribute("msg", msg); 27 //return redirect("/login"); 28 return "redirect:login"; 29 //return msg; 30 }
此時登陸認證部門已經完成:一個頁面+後臺2個函數(1個認證函數+1個Login函數)apache
整體來講,權限管理只須要在界面增長 Shiro 的權限標籤便可,可使用角色的標籤,也可使用權限的標籤,通常狀況下2種標籤配合使用,效果最好 <@shiro.hasPermission name="xtgl-yhgl:read">
<@shiro.hasRolen name="xtgl-yhgl:read">
緩存
authorizationInfo.setStringPermissions(permissions);
authorizationInfo.setRoles(role);
本項目也是經過此邏輯完成權限管理的安全
上面2張截圖表示的是一個函數。session
到此,Spring Boot集成Shiro框架的權限認證已經搭建完畢,能夠實現簡單的權限管理。
