TLS Spring HttpInvokerProxyFactoryBean

// First write a custom class of org.springframework.remoting.httpinvoker.HttpComponentsHttpInvokerRequestExecutor :

package com.myorg.proid.sample;

import static org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;

import java.security.KeyManagementException;
import java.security.KeyStoreException;

import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.conn.ssl.TrustStrategy;
import org.springframework.remoting.httpinvoker.HttpComponentsHttpInvokerRequestExecutor;

public class CustomHttpComponentsHttpInvokerRequestExecutor extends

        try {
