一：先從登錄開始，直接看代碼
@RequestMapping(value="dologin",method = {RequestMethod.GET, RequestMethod.POST},produces="text/html;charset=UTF-8")
@ResponseBody
public ResultJson systemUserdologin(XXX xxx,HttpServletRequest request,HttpServletResponse response, Model model) {
logger.info("=================dologin==============");
response.setHeader("Access-Control-Allow-Origin","*");//跨域
String msg=null ;
Subject currentuser = SecurityUtils.getSubject();
CustomizedToken token = new CustomizedToken(user.getUsername(),user.getUserpassword(),ADMIN_LOGIN_TYPE);//設置多realm驗證的type
try {
if(!currentuser.isAuthenticated()){
// 指明登錄類型為管理員登錄(在授權時使用)
currentuser.getSession().setAttribute("loginType", ADMIN_LOGIN_TYPE);
//將管理員姓名保存到session中，方便在前台使用
currentuser.getSession().setAttribute("userName",xxx.getname());
token.setRememberMe(xxx.isRememberMe());
currentuser.login(token);//開始認證
if (currentuser.isAuthenticated()) {
logger.info("=================認證成功==============");
request.getSession().setAttribute("xxx",xxx);
user.setUserstatus(2);//設置用戶登錄狀態為已登錄
SavedRequest savedRequest = WebUtils.getSavedRequest(request);
// 獲取保存的URL
if (savedRequest == null || savedRequest.getRequestUrl() == null) {
return new ResultJson(true, "身份認證成功,跳轉到主頁面", "");
} else {
return new ResultJson(true, "身份認證成功,跳轉到主頁面", "");
}
} else {
logger.info("=================認證失敗==============");
return new ResultJson(false, "身份認證失敗,跳轉到登錄頁面", "");
}
}else{
return new ResultJson(true, "已認證,跳轉到主頁面", "");
}
} catch (IncorrectCredentialsException e) {
msg = "登錄密碼錯誤. Password for account " + token.getPrincipal() + " was incorrect.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (ExcessiveAttemptsException e) {
msg = "登錄失敗次數過多";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (LockedAccountException e) {
msg = "帳號已被鎖定. The account for username " + token.getPrincipal() + " was locked.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (DisabledAccountException e) {
msg = "帳號已被禁用. The account for username " + token.getPrincipal() + " was disabled.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (ExpiredCredentialsException e) {
msg = "帳號已過期. the account for username " + token.getPrincipal() + " was expired.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (UnknownAccountException e) {
msg = "帳號不存在. There is no user with username of " + token.getPrincipal();
model.addAttribute("message", msg);
System.out.println(msg);
} catch (UnauthorizedException e) {
msg = "您沒有得到相應的授權！" + e.getMessage();
model.addAttribute("message", msg);
System.out.println(msg);
}
return new ResultJson(false, "身份認證失敗,跳轉到登錄頁面", "");
}
二、在realm中進行驗證
/** * 首先執行這個登錄驗證，身份認證 * @param token * @return * @throws AuthenticationException */ @SuppressWarnings("unused") @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("----->doGetAuthenticationInfo-->身份認證"+22222); //1.把AuthenticationToken轉換為UsernamePasswordToken,token中儲存着輸入的用戶名和密碼 ,用戶名用來確定賬號是否存在,密碼用來鹽值加密 CustomizedToken userToken = (CustomizedToken) token; //2.獲取系統管理員賬號 String username = userToken.getUsername() ; //3.根據系統管理員賬號獲取系統管理員信息 SystemUser user = userMapper.findUserByUsername(username) ; System.out.println("user---------->"+user.toString()); //4.系統管理員存在則進行密碼校驗，否則，拋出異常：系統管理員不存在; if (user!= null){ String roleName = userMapper.findRoles(username); //將前台需要的值放到session中去，方便使用 SecurityUtils.getSubject().getSession().setAttribute("roleName",roleName); SecurityUtils.getSubject().getSession().setAttribute("id",user.getId()); System.out.println("從數據看中獲取UserName為"+user.getUsername()+"所對應的信息。"); //1)principal：認證的實體信息，可以是username，也可以是數據庫表對應的用戶的實體對象 Object principal = user.getUsername(); //2)credentials：數據庫中的密碼 Object credentials = user.getUserpassword(); //3)realmName：當前realm對象的name，調用父類的getName()方法即可 String realmName = getName(); //4)credentialsSalt鹽值 ByteSource credentialsSalt = ByteSource.Util.bytes(username);//使用賬號作為鹽值 //根據用戶的情況，來構建AuthenticationInfo對象,通常使用的實現類為SimpleAuthenticationInfo //5)與數據庫中用戶名和密碼進行比對，密碼鹽值加密，第4個參數傳入realName。 SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(principal, credentials, credentialsSalt, realmName); return info; }else{ //6.若用戶不存在，可以拋出UnknownAccountException System.out.println("======不存在該用戶=========>"); throw new UnknownAccountException("不存在該用戶");//沒找到帳號 } }
三、以上便是登錄和驗證，但是問題是，shiro如何知道我們的密碼時以什么方式加密的，加密了多少次呢？
具體配置如下：在配置realm的bean時，設置加密類型及加密的次數，這樣shiro就知道了該如何對用戶輸入的密碼進行驗證，如果正確就驗證通過，否則，驗證失敗
<!-- 注冊自定義的Realm--> <bean id="XXXRealm" class="com.shiro.XXXRealm"> <!-- 配置密碼匹配器 --> <property name="credentialsMatcher"> <bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher"> <!-- 加密算法為MD5 --> <property name="hashAlgorithmName" value="MD5"></property> <!-- 加密次數 --> <property name="hashIterations" value="1024"></property> </bean> </property> </bean> <bean id="YYYRealm" class="com.shiro.YYYRealm"> <!-- 配置密碼匹配器 --> <property name="credentialsMatcher"> <bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher"> <!-- 加密算法為MD5 --> <property name="hashAlgorithmName" value="MD5"></property> <!-- 加密次數 --> <property name="hashIterations" value="1024"></property> </bean> </property> </bean> <bean id="cacheManager" class="org.apache.shiro.cache.MemoryConstrainedCacheManager" /> <!-- 安全管理器 --> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="cacheManager" ref="cacheManager" /> <property name="authenticator" ref="authenticator"></property> <!-- 使用下面配置的緩存管理器 --> <property name="sessionManager" ref="sessionManager" /> <!-- 可以配置多個Realm，其實會把realms屬性賦值給ModularRealmAuthenticator的realms屬性 --> <property name="realms"> <list> <ref bean="XXXRealm"/> <ref bean="YYYRealm" /> </list> </property> </bean>
以上是登錄的密碼驗證；
四、那注冊加密如何實現呢？
首先一定要保證注冊時的加密方式和上面的shiro的加密方式和加密的次數一致，否則注冊成功也登陸不上去，這點一定要清楚！
/******************************添加用戶******************************************/ @RequestMapping("addUser") @ResponseBody public ResultJson addUser(XXX xxx,HttpServletRequest request){ System.out.println("======addUser======="); System.out.println(xxx.toString());
//密碼加密並set user.setUserpassword(ShiroMd5Util.SysMd5(xxx)); ResultJson rj = new ResultJson(); boolean addUser_bl = userService.add(user);//將用戶數據插入數據庫 if (addUser_bl) { rj.setSuccess(addUser_bl); rj.setMsg("注冊成功!"); }else{ rj.setSuccess(addUser_boolean); rj.setMsg("注冊失敗!"); } return rj; }
public class ShiroMd5Util { //添加user的密碼加密方法 public static String SysMd5(XXX xxx) { String hashAlgorithmName = "MD5";//加密方式 Object crdentials =xxx.getUserpassword();//密碼原值 ByteSource salt = ByteSource.Util.bytes(xxx.getUsername());//以賬號作為鹽值 int hashIterations = 1024;//加密1024次 SimpleHash hash = new SimpleHash(hashAlgorithmName,crdentials,salt,hashIterations); return hash.toString(); } }
注冊時密碼加密如上即可；
五、修改密碼時如下：
/******************************更新用戶******************************************/ @RequestMapping("updateUser") @ResponseBody public ResultJson updateUser(XXX xxx,HttpServletRequest request){ System.out.println("======updateUser======="); if(xxx.getId()==null){ return new ResultJson(false, "修改失敗", "不存在該用戶"); }//從數據哭獲取的密碼值 String dataBaseOldPassword = userService.selectSystemUserPassword(xxx.getId()); System.out.println("dataBaseOldPassword="+dataBaseOldPassword); //從頁面傳過來的舊密碼值 String pageReturnOldPassword =ShiroMd5Util.UpdateSysMd5(xxx);//這個方法和上面的SysMd5一樣，就是換了個馬甲 System.out.println("pageReturnOldPassword="+pageReturnOldPassword); if(!dataBaseOldPassword.equals(pageReturnOldPassword)){ return new ResultJson(false, "修改失敗", "舊密碼不正確"); } //如果輸入的舊密碼和數據庫一致，則將用戶傳進來的新密碼覆蓋舊密碼，修改密碼 user.setUserpassword(ShiroMd5Util.SysMd5(user)); ResultJson rj = new ResultJson(); //根據傳進來的xxx的值是否存在更新數據 boolean upbl = userService.updateByPrimaryKeySelective(xxx); if(upbl){ rj.setSuccess(upbl); rj.setMsg("修改成功"); rj.setObj("1"); }else{ rj.setSuccess(upbl); rj.setMsg("修改失敗"); rj.setObj("0"); } return rj; }
