heroku：spring boot仅使用https接入端点

heroku：spring boot仅使用https接入端点

实际上，我已经在此仓库https://github.com/fenrirx22/springmvc-https-
enforcer中
找到了一个解决方案（终于）。

创建了2个课程：

@Configurationpublic class ApiConfig {    @Bean    public Filter httpsEnforcerFilter(){        return new HttpsEnforcer();    }}

和：

public class HttpsEnforcer implements Filter {    private FilterConfig filterConfig;    public static final String X_FORWARDED_PROTO = "x-forwarded-proto";    @Override    public void init(FilterConfig filterConfig) throws ServletException {        this.filterConfig = filterConfig;    }    @Override    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {        HttpServletRequest request = (HttpServletRequest) servletRequest;        HttpServletResponse response = (HttpServletResponse) servletResponse;        if (request.getHeader(X_FORWARDED_PROTO) != null) { if (request.getHeader(X_FORWARDED_PROTO).indexOf("https") != 0) {     response.sendRedirect("https://" + request.getServerName() + request.getPathInfo());     return; }        }        filterChain.doFilter(request, response);    }    @Override    public void destroy() {        // nothing    }}

奇迹般有效。
