一Spring Security介绍
安全方面的两个核心功能是认证和授权,一般来说,Web 应用的安全性包括**用户认证(Authentication)和用户授权(Authorization)**两个部分,
二 和Shiro比较
SpringSecurity 特点:
- 和 Spring 无缝整合。
- 专门为 Web 开发而设计。
- 重量级
- 能整合分布式
Shiro特点
- 轻量级。Shiro 主张的理念是把复杂的事情变简单。针对对性能有更高要求
- 不能和分布式使用,简单的什么不分离,有这个就够了
- Subject、SecurityManager 和 Realms.
- Apache 旗下的轻量级权限控制框架。
共同点
- 认证功能
- 授权功能
- 加密功能
- 会话管理
- 缓存支持
- rememberMe功能
三 内部组织和流程
别人画好的直接拿来用
四 参观一下若依
/**
* 登录验证
*
* @param username 用户名
* @param password 密码
* @param code 验证码
* @param uuid 唯一标识
* @return 结果
*/
public String login(String username, String password, String code, String uuid){
// 验证码校验
validateCaptcha(username, code, uuid);
// 登录前置校验 主要是参数和登录ip的检验
loginPreCheck(username, password);
// 用户验证
Authentication authentication = null;
try{
UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(username, password);
AuthenticationContextHolder.setContext(authenticationToken);
// 该方法会去调用UserDetailsServiceImpl.loadUserByUsername
authentication = authenticationManager.authenticate(authenticationToken);
}
catch (Exception e){
if (e instanceof BadCredentialsException){
AsyncManager.me().execute(AsyncFactory.recordLogininfor(username,Constants.LOGIN_FAIL, MessageUtils.message("user.password.not.match")));
throw new UserPasswordNotMatchException();
}else{
AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, e.getMessage()));
throw new ServiceException(e.getMessage());
}
}
finally{
AuthenticationContextHolder.clearContext();
}
AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_SUCCESS, MessageUtils.message("user.login.success")));
LoginUser loginUser = (LoginUser) authentication.getPrincipal();
recordLoginInfo(loginUser.getUserId());
// 生成token
return tokenService.createToken(loginUser);
}
AuthenticationContextHolder 是一个ThreadLocal的工具类 用作存储用户信息的
AsyncManager是一个异步处理国际化和日志的工具类
AuthenticationManager的校验逻辑,逻辑在UserDetialsService接口处理,该接口只有一个方法loadUserByUsername(String username)
,通过用户名查询用户对象,默认实现是在内存中查询。
