Java配置HTTP2协议发送请求_java http2请求

发送HTTP2请求

1、下载Tomcat证书

①第一步：打开阿里云控制台

打开阿里云控制台，进入SSL证书管理，选择Tomcat证书下载

②第二步：下载证书

将下载的证书（pfx证书和txt秘钥）复制到项目中

2、HTTP2配置文件

# 端口：9443或443
server.port=9443
# 开启http2协议
server.http2.enabled=true
# 进行SSL加密协议
server.ssl.enabled=true
# 证书路径
server.ssl.key-store=classpath:9260452_www.yunkeyo.com.pfx
# 秘钥
server.ssl.key-store-password=hxxhtf0a
# 秘钥方式：PKCS12默认
server.ssl.key-store-type=PKCS12

3、关闭HTTP1.1协议请求

@Bean
public FilterRegistrationBean<OncePerRequestFilter> httpsRedirectFilter() {
    FilterRegistrationBean<OncePerRequestFilter> filterRegistrationBean = new FilterRegistrationBean<>();
    filterRegistrationBean.setFilter(new OncePerRequestFilter() {
        @Override
        protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
            if (!request.isSecure()) {
                String url = "https://" + request.getServerName() + request.getRequestURI();
                response.sendRedirect(url);
                return;
            }
            filterChain.doFilter(request, response);
        }
    });
    filterRegistrationBean.setOrder(Ordered.HIGHEST_PRECEDENCE);
    return filterRegistrationBean;
}

4、启动测试

注意：此处必须为https，因为http协议已经被关闭了，如果需要http协议同样生效，请自行删除上述代码

发送http2协议请求 成功！
