springboot1.5.x 第一部分 自定义用户认证

按图引入包

此时，所有的接口都被保护起来，访问接口都会出现提示框如下

最基本配置如下：

 效果如下：

 控制台会有一个生成的密码：

基本原理，是每个过滤器处理一种认证方式：

 

自定义用户认证逻辑：

 

 UserDetails和User类都是框架自带，User类带有很多属性方法，比如是否过期之类的，按需使用。如下，就多用几个

 加密解密器，用上面一个

 可以使用自带的实现类，也可以自己实现类

    @Autowired

     */
    @RequestMapping("/authentication/require")
    @ResponseStatus(code = HttpStatus.UNAUTHORIZED)
    public SimpleResponse requireAuthentication(HttpServletRequest request, HttpServletResponse response) throws IOException {

        SavedRequest savedRequest = requestCache.getRequest(request, response);

        if (savedRequest != null) {
            String targetUrl = savedRequest.getRedirectUrl();
            logger.info("引发跳转的请求是:"+targetUrl);
            if(StringUtils.endsWithIgnoreCase(targetUrl, ".html")){
                redirectStrategy.sendRedirect(request, response, securityProperties.getBrowser().getLoginPage());
            }
        }

        return new SimpleResponse("访问的服务需要身份认证，请引导用户到登录页");
    }

}

自定义成功处理器，失败处理器

加入配置

 

下面改进，可以继承框架已有的类，复用逻辑
