验证服务器整数实现类

目前没有做任何处理，有需要验证服务器证书时，可以在对应的重写方法中进行处理

package com.demo.client;
import java.security.PublicKey;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.X509TrustManager;
public class SSLX509TrustMgr implements X509TrustManager {
    private PublicKey serverPublicKey;
    public SSLX509TrustMgr() {
    public SSLX509TrustMgr(PublicKey serverPublicKey) {
        this.serverPublicKey = serverPublicKey;
    @Override
    public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        // TODO Auto-generated method stub
    @Override
    public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        // TODO Auto-generated method stub
    @Override
    public X509Certificate[] getAcceptedIssuers() {
        // TODO Auto-generated method stub
        return null;

1、demo使用的springboot版本为2.3.3
2、HttpClient的create方法与secure方法不能分开，否则secure方法可能不生效
3、 ConnectionProvider中有很多方法已经过时，比如fixed，elastic，不建议使用，在过时的方法上，源码中也给出了对应替换使用的方法，比如fixed可以使用create方法替代，elastic方法可以用builder方法替代，但create方法直接创建的就为ConnectionProvider，重载的方法可以设置maxConnections，但不能设置连接最大空闲时间，连接最大生命周期等，builder方法可以对线程更精细的管理，故本例使用的builder方法和build来创建ConnectionProvider，如果使用默认的provider，线程数默认500，且maxIdleTime和maxLifeTime为-1
4、LoopResources为处理响应消息的线程数，2.3.3版本最小值为4
 5、ReactorClientHttpConnector存在一个重构方法
在该方法中，factory可以设置ConnectionProvider和LoopResources，mapper可以设置HttpClient，但在使用时可能是使用方式不正确，一直都是要么线程池配置上了，但SSL不可用，或者是SSL可用，但线程池不可用，后在ReactorClientHttpConnector两个参数的构造方法中看到initHttpClient方法，该方法中，使用了runOn配置LoopResources，故本例中也是用了runOn来配置。
@Override
    public void run(String... args) throws Exception {
        int count = 6;
        for (int i = 0; i < count; i++) {
            logger.info("start: {}", i);
            JsonObject obj = new JsonObject();
            obj.addProperty("name", "name"+i);
            obj.addProperty("age", i);
            Mono<String> mono = WebClientUtil.doPost(url, obj.toString(), keyStorePath);
            mono.subscribe(new MainConsumer(i));
            logger.info("end: {}", i);
    class MainConsumer implements Consumer<String> {
        private int i;
        public MainConsumer(int i) {

        public void accept(String t) {
            logger.info("receive: {}, loop: {}", t, i);

 6、本例中，使用了一个reactor-extra进行重试处理
<dependency>
       <groupId>io.projectreactor.addons</groupId>
       <artifactId>reactor-extra</artifactId>
 </dependency>
但这种重试的方法虽然比较简单好用，但已经被标记为过时
应该使用传递一个reactor.util.retry.Retry类型参数的方法
 7、如果使用springclloud，则需要考虑springboot和springcloud的兼容问题，以及当前程序的springboot和springcloud版本与其他需要远程调用的版本的兼容
