1。运行VirutalBox（VirtualBox.exe），不要运行虚拟机；2。打开寄主机的“网络连接”页面，记下“virtualbox host-only network”的网络设置（我的默认设置为（安装完VirtualBox后，网络连接就自动多了个VirtualBox Host-Only Network）：IP地址为192.168.56.1，掩码为255.255.255.0）；3。启动虚拟机，将虚拟机的网络设置如下：IP地址：192.168.56.2掩码：255.255.255.0网关：192.168.56.1（我的试验发现，不需要设置DNS）；4。尝试宿主机与虚拟机互ping如果发现ping不通，主要的可能原因是防火墙拦截了互ping时，可以将2台计算机的防火墙先关闭，证明互ping成功后再打开防火墙5。我的目标是宿主机连接使用虚拟机的数据库服务，SQLServer的默认端口为：1433，因此，对虚拟机 Windows XP防火墙设置例外端口，使得宿主机可连接虚拟机，对虚拟机 Windows XP设置如下：开始-->控制面板-->Windows防火墙-->点击“例外”选项卡-->点击“添加端口”按钮起一个容易记的名字，端口为：1433，单选按钮：TCP，点确定。宿主机测试是否能连接：在Windows 7WIN+R-->cmd-->telnet 192.168.68.2 1433出现新的命令窗口，命令窗口的标题是“telnet 192.168.68.2”，就证明成功了。如果告诉你telnet不是内部命令，依次打开“开始”→“控制面板”→“打开或关闭Windows功能”，在打开的窗口处，寻找并勾选“Telnet客户端”，然后点击“确定”。顺利安装后，再在运行下输入此命令就OK了。 通过Host-Only使宿主机与虚拟机通信，此时虚拟机无法访问外网。要解决该问题，最简单的方法是：为虚拟机再设置一块网卡，连接方式为NAT 另外，如果有路由器，则通过桥接方式（Bridge）就可以实现既互相通信又能上网了，因为此时宿主机与虚拟机是局域网上两台平等的计算机。

 在项目开发过程中，我想大部分系统都需要对接另外的系统。对接方式有很多种，现在最常见的就是https请求了。现将Java发送https请求的工具类整理一下，有需要用到的同学拿走不谢。

  该方法使用apache的httpclient实现

第一步：创建SSLClient

import java.security.cert.CertificateException

import java.security.cert.X509Certificate

import javax.net.ssl.SSLContext

import javax.net.ssl.TrustManager

import javax.net.ssl.X509TrustManager

import org.apache.http.conn.ClientConnectionManager

import org.apache.http.conn.scheme.Scheme

import org.apache.http.conn.scheme.SchemeRegistry

import org.apache.http.conn.ssl.SSLSocketFactory

import org.apache.http.impl.client.DefaultHttpClient

public class SSLClient extends DefaultHttpClient{

public SSLClient() throws Exception{

super()

SSLContext ctx = SSLContext.getInstance("TLS")

X509TrustManager tm = new X509TrustManager() {

@Override

public void checkClientTrusted(X509Certificate[] chain,

String authType) throws CertificateException {

}

@Override

public void checkServerTrusted(X509Certificate[] chain,

String authType) throws CertificateException {

}

@Override

public X509Certificate[] getAcceptedIssuers() {

return null

}

}

ctx.init(null, new TrustManager[]{tm}, null)

SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER)

ClientConnectionManager ccm = this.getConnectionManager()

SchemeRegistry sr = ccm.getSchemeRegistry()

sr.register(new Scheme("https", 443, ssf))

}

}

第二步：实现自己的https工具类

import org.apache.http.HttpEntity

import org.apache.http.HttpResponse

import org.apache.http.client.HttpClient

import org.apache.http.client.methods.HttpGet

import org.apache.http.client.methods.HttpPost

import org.apache.http.entity.StringEntity

import org.apache.http.message.BasicHeader

import org.apache.http.protocol.HTTP

import org.apache.http.util.EntityUtils

import java.util.Map

public class HttpsClientUtil {

private static final String CHAREST = "utf-8"

/**

* 发送post请求

* @param url

* @return

*/

public static String doPost(String url,String mapParam){

HttpClient httpClient = null

HttpPost httpPost = null

String result = null

try{

httpClient = new SSLClient()

httpPost = new HttpPost(url)

//设置参数

httpPost.setHeader("Content-Type", "application/json")

httpPost.addHeader("Authorization", "Basic YWRtaW46")

StringEntity s = new StringEntity(mapParam, CHAREST)

s.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json"))

httpPost.setEntity(s)

HttpResponse response = httpClient.execute(httpPost)

if(response != null){

HttpEntity resEntity = response.getEntity()

if(resEntity != null){

result = EntityUtils.toString(resEntity,CHAREST)

}

}

}catch(Exception ex){

ex.printStackTrace()

}

return result

}

/**

* 发送get请求

* @param url      链接地址

* @return

*/

public static String doGet(String url){

HttpClient httpClient = null

HttpGet httpGet= null

String result = null

try {

httpClient = new SSLClient()

httpGet = new HttpGet(url)

HttpResponse response = httpClient.execute(httpGet)

if(response != null){

HttpEntity resEntity = response.getEntity()

if(resEntity != null){

result = EntityUtils.toString(resEntity,CHAREST)

}

}

} catch (Exception e) {

e.printStackTrace()

}

return result

}

/**

* 发送get请求,并设置get的请求头

* @param url      链接地址

* @return

*/

public static String setHeadDoGet(String url,Map headers){

HttpClient httpClient = null

HttpGet httpGet= null

String result = null

try {

httpClient = new SSLClient()

httpGet = new HttpGet(url)

for (Map.Entry e : headers.entrySet()) {

httpGet.addHeader(e.getKey(), e.getValue())

}

HttpResponse response = httpClient.execute(httpGet)

if(response != null){

HttpEntity resEntity = response.getEntity()

if(resEntity != null){

result = EntityUtils.toString(resEntity,CHAREST)

}

}

} catch (Exception e) {

e.printStackTrace()

}

return result

}

}

ps:有需要设置post请求头的请求，同学们可以参考setHeadDoGet方法进行编写。 需要用到的apache的httpclient-4.5.9.jar包 。
