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;
    }
