Shiro自定义realm实现密码验证及登录、密码加密注册、修改密码的验证
一：先从登录开始，直接看代码
@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);//设置多realm验证的type
try {
if(!currentuser.isAuthenticated()){
// 指明登录类型为管理员登录(在授权时使用)
currentuser.getSession().setAttribute("loginType", ADMIN_LOGIN_TYPE);
//将管理员姓名保存到session中，方便在前台使用
currentuser.getSession().setAttribute("userName",xxx.getname());
token.setRememberMe(xxx.isRememberMe());
currentuser.login(token);//开始认证
if (currentuser.isAuthenticated()) {
logger.info("=================认证成功==============");
request.getSession().setAttribute("xxx",xxx);
user.setUserstatus(2);//设置用户登录状态为已登录
SavedRequest savedRequest = WebUtils.getSavedRequest(request);
// 获取保存的URL
if (savedRequest == null || savedRequest.getRequestUrl() == null) {
return new ResultJson(true, "身份认证成功,跳转到主页面", "");
} else {
return new ResultJson(true, "身份认证成功,跳转到主页面", "");
}
} else {
logger.info("=================认证失败==============");
return new ResultJson(false, "身份认证失败,跳转到登录页面", "");
}
}else{
return new ResultJson(true, "已认证,跳转到主页面", "");
}
} catch (IncorrectCredentialsException e) {
msg = "登录密码错误. Password for account " + token.getPrincipal() + " was incorrect.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (ExcessiveAttemptsException e) {
msg = "登录失败次数过多";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (LockedAccountException e) {
msg = "帐号已被锁定. The account for username " + token.getPrincipal() + " was locked.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (DisabledAccountException e) {
msg = "帐号已被禁用. The account for username " + token.getPrincipal() + " was disabled.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (ExpiredCredentialsException e) {
msg = "帐号已过期. the account for username " + token.getPrincipal() + " was expired.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (UnknownAccountException e) {
msg = "帐号不存在. There is no user with username of " + token.getPrincipal();
model.addAttribute("message", msg);
System.out.println(msg);
} catch (UnauthorizedException e) {
msg = "您没有得到相应的授权！" + e.getMessage();
model.addAttribute("message", msg);
System.out.println(msg);
}
return new ResultJson(false, "身份认证失败,跳转到登录页面", "");
}
二、在realm中进行验证
/** * 首先执行这个登录验证，身份认证 * @param token * @return * @throws AuthenticationException */ @SuppressWarnings("unused") @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("----->doGetAuthenticationInfo-->身份认证"+22222); //1.把AuthenticationToken转换为UsernamePasswordToken,token中储存着输入的用户名和密码 ,用户名用来确定账号是否存在,密码用来盐值加密 CustomizedToken userToken = (CustomizedToken) token; //2.获取系统管理员账号 String username = userToken.getUsername() ; //3.根据系统管理员账号获取系统管理员信息 SystemUser user = userMapper.findUserByUsername(username) ; System.out.println("user---------->"+user.toString()); //4.系统管理员存在则进行密码校验，否则，抛出异常：系统管理员不存在; if (user!= null){ String roleName = userMapper.findRoles(username); //将前台需要的值放到session中去，方便使用 SecurityUtils.getSubject().getSession().setAttribute("roleName",roleName); SecurityUtils.getSubject().getSession().setAttribute("id",user.getId()); System.out.println("从数据看中获取UserName为"+user.getUsername()+"所对应的信息。"); //1)principal：认证的实体信息，可以是username，也可以是数据库表对应的用户的实体对象 Object principal = user.getUsername(); //2)credentials：数据库中的密码 Object credentials = user.getUserpassword(); //3)realmName：当前realm对象的name，调用父类的getName()方法即可 String realmName = getName(); //4)credentialsSalt盐值 ByteSource credentialsSalt = ByteSource.Util.bytes(username);//使用账号作为盐值 //根据用户的情况，来构建AuthenticationInfo对象,通常使用的实现类为SimpleAuthenticationInfo //5)与数据库中用户名和密码进行比对，密码盐值加密，第4个参数传入realName。 SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(principal, credentials, credentialsSalt, realmName); return info; }else{ //6.若用户不存在，可以抛出UnknownAccountException System.out.println("======不存在该用户=========>"); throw new UnknownAccountException("不存在该用户");//没找到帐号 } }
三、以上便是登录和验证，但是问题是，shiro如何知道我们的密码时以什么方式加密的，加密了多少次呢？
具体配置如下：在配置realm的bean时，设置加密类型及加密的次数，这样shiro就知道了该如何对用户输入的密码进行验证，如果正确就验证通过，否则，验证失败
<!-- 注册自定义的Realm--> <bean id="XXXRealm" class="com.shiro.XXXRealm"> <!-- 配置密码匹配器 --> <property name="credentialsMatcher"> <bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher"> <!-- 加密算法为MD5 --> <property name="hashAlgorithmName" value="MD5"></property> <!-- 加密次数 --> <property name="hashIterations" value="1024"></property> </bean> </property> </bean> <bean id="YYYRealm" class="com.shiro.YYYRealm"> <!-- 配置密码匹配器 --> <property name="credentialsMatcher"> <bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher"> <!-- 加密算法为MD5 --> <property name="hashAlgorithmName" value="MD5"></property> <!-- 加密次数 --> <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> <!-- 使用下面配置的缓存管理器 --> <property name="sessionManager" ref="sessionManager" /> <!-- 可以配置多个Realm，其实会把realms属性赋值给ModularRealmAuthenticator的realms属性 --> <property name="realms"> <list> <ref bean="XXXRealm"/> <ref bean="YYYRealm" /> </list> </property> </bean>
以上是登录的密码验证；
四、那注册加密如何实现呢？
首先一定要保证注册时的加密方式和上面的shiro的加密方式和加密的次数一致，否则注册成功也登陆不上去，这点一定要清楚！
/******************************添加用户******************************************/ @RequestMapping("addUser") @ResponseBody public ResultJson addUser(XXX xxx,HttpServletRequest request){ System.out.println("======addUser======="); System.out.println(xxx.toString());
//密码加密并set user.setUserpassword(ShiroMd5Util.SysMd5(xxx)); ResultJson rj = new ResultJson(); boolean addUser_bl = userService.add(user);//将用户数据插入数据库 if (addUser_bl) { rj.setSuccess(addUser_bl); rj.setMsg("注册成功!"); }else{ rj.setSuccess(addUser_boolean); rj.setMsg("注册失败!"); } return rj; }
public class ShiroMd5Util { //添加user的密码加密方法 public static String SysMd5(XXX xxx) { String hashAlgorithmName = "MD5";//加密方式 Object crdentials =xxx.getUserpassword();//密码原值 ByteSource salt = ByteSource.Util.bytes(xxx.getUsername());//以账号作为盐值 int hashIterations = 1024;//加密1024次 SimpleHash hash = new SimpleHash(hashAlgorithmName,crdentials,salt,hashIterations); return hash.toString(); } }
注册时密码加密如上即可；
五、修改密码时如下：
/******************************更新用户******************************************/ @RequestMapping("updateUser") @ResponseBody public ResultJson updateUser(XXX xxx,HttpServletRequest request){ System.out.println("======updateUser======="); if(xxx.getId()==null){ return new ResultJson(false, "修改失败", "不存在该用户"); }//从数据哭获取的密码值 String dataBaseOldPassword = userService.selectSystemUserPassword(xxx.getId()); System.out.println("dataBaseOldPassword="+dataBaseOldPassword); //从页面传过来的旧密码值 String pageReturnOldPassword =ShiroMd5Util.UpdateSysMd5(xxx);//这个方法和上面的SysMd5一样，就是换了个马甲 System.out.println("pageReturnOldPassword="+pageReturnOldPassword); if(!dataBaseOldPassword.equals(pageReturnOldPassword)){ return new ResultJson(false, "修改失败", "旧密码不正确"); } //如果输入的旧密码和数据库一致，则将用户传进来的新密码覆盖旧密码，修改密码 user.setUserpassword(ShiroMd5Util.SysMd5(user)); ResultJson rj = new ResultJson(); //根据传进来的xxx的值是否存在更新数据 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("修改失败"); rj.setObj("0"); } return rj; }
相关JSp页面代码如下,只粘贴关键代码：

end!
