接下來我們將域名www.zlex.org定位到本機上。打開C:\Windows\System32\drivers\etc\hosts文件，將www.zlex.org綁定在本機上。在文件末尾追加127.0.0.1 www.zlex.org。現在通過地址欄訪問http://www.zlex.org，或者通過ping命令，如果能夠定位到本機，域名映射就搞定了。
現在，配置tomcat。先將zlex.keystore拷貝到tomcat的conf目錄下，然后配置server.xml。將如下內容加入配置文件
[xml] view plain copy
<Connector
SSLEnabled="true"
URIEncoding="UTF-8"
clientAuth="false"
keystoreFile="conf/zlex.keystore"
keystorePass="123456"
maxThreads="150"
port="443"
protocol="HTTP/1.1"
scheme="https"
secure="true"
sslProtocol="TLS" />
注意clientAuth="false"測試階段，置為false，正式使用時建議使用true。現在啟動tomcat，訪問https://www.zlex.org/。
顯然，證書未能通過認證，這個時候你可以選擇安裝證書（上文中的zlex.cer文件就是證書），作為受信任的根證書頒發機構導入，再次重啟瀏覽器（IE，其他瀏覽器對於域名www.zlex.org不支持本地方式訪問），訪問https://www.zlex.org/，你會看到地址欄中會有個小鎖，就說明安裝成功。所有的瀏覽器聯網操作已經在RSA加密解密系統的保護之下了。但似乎我們感受不到。
這個時候很多人開始懷疑，如果我們要手工做一個這樣的https的訪問是不是需要把瀏覽器的這些個功能都實現呢？不需要！
接着上篇內容，給出如下代碼實現：

增加了configSSLSocketFactory方法供外界調用，該方法為 HttpsURLConnection配置了SSLSocketFactory。當HttpsURLConnection配置了 SSLSocketFactory后，我們就可以通過HttpsURLConnection的getInputStream、 getOutputStream，像往常使用HttpURLConnection做操作了。尤其要說明一點，未配置SSLSocketFactory 前，HttpsURLConnection的getContentLength()獲得值永遠都是-1。

通過瀏覽器直接訪問https://www.zlex.org/examples/你 也會獲得上述內容。也就是說應用甲方作為服務器構建tomcat服務，乙方可以通過上述方式訪問甲方受保護的SSL應用，並且不需要考慮具體的加密解密問 題。甲乙雙方可以經過相應配置，通過雙方的tomcat配置有效的SSL服務，簡化上述代碼實現，完全通過證書配置完成SSL雙向認證！
我們使用自簽名證書完成了認證。接下來，我們使用第三方CA簽名機構完成證書簽名。
這里我們使用thawte提供的測試用21天免費ca證書。
1.要在該網站上注明你的域名，這里使用www.zlex.org作為測試用域名（請勿使用該域名作為你的域名地址，該域名受法律保護！請使用其他非注冊域名！）。
2.如果域名有效，你會收到郵件要求你訪問https://www.thawte.com/cgi/server/try.exe獲得ca證書。
3.復述密鑰庫的創建。
keytool -genkey -validity 36000 -alias www.zlex.org -keyalg RSA -keystore d:\zlex.keystore
在這里我使用的密碼為 123456
控制台輸出：
輸入keystore密碼：
再次輸入新密碼:
您的名字與姓氏是什么？
[Unknown]： www.zlex.org
您的組織單位名稱是什么？
[Unknown]： zlex
您的組織名稱是什么？
[Unknown]： zlex
您所在的城市或區域名稱是什么？
[Unknown]： BJ
您所在的州或省份名稱是什么？
[Unknown]： BJ
該單位的兩字母國家代碼是什么
[Unknown]： CN
CN=www.zlex.org, OU=zlex, O=zlex, L=BJ, ST=BJ, C=CN 正確嗎？
[否]： Y
輸入<tomcat>的主密碼
（如果和 keystore 密碼相同，按回車）：
再次輸入新密碼:
4.通過如下命令，從zlex.keystore中導出CA證書申請。
keytool -certreq -alias www.zlex.org -file d:\zlex.csr -keystore d:\zlex.keystore -v
你會獲得zlex.csr文件，可以用記事本打開，內容如下格式：

將其存儲為zlex.p7b
6.將由CA簽發的證書導入密鑰庫。
keytool -import -trustcacerts -alias www.zlex.org -file d:\zlex.p7b -keystore d:\zlex.keystore -v
在這里我使用的密碼為 123456
控制台輸出：

認證回復已安裝在 keystore中
[正在存儲 d:\zlex.keystore]
7.域名定位
將域名www.zlex.org定位到本機上。打開C:\Windows\System32\drivers\etc\hosts文件，將 www.zlex.org綁定在本機上。在文件末尾追加127.0.0.1 www.zlex.org。現在通過地址欄訪問http://www.zlex.org，或者通過ping命令，如果能夠定位到本機，域名映射就搞定 了。
8.配置server.xml
[xml] view plain copy
<Connector
keystoreFile="conf/zlex.keystore"
keystorePass="123456"
truststoreFile="conf/zlex.keystore"
truststorePass="123456"
SSLEnabled="true"
URIEncoding="UTF-8"
clientAuth="false"
maxThreads="150"
port="443"
protocol="HTTP/1.1"
scheme="https"
secure="true"
sslProtocol="TLS" />
將文件zlex.keystore拷貝到tomcat的conf目錄下，重新啟動tomcat。訪問https://www.zlex.org/，我們發現聯網有些遲鈍。大約5秒鍾后，網頁正常顯示，同時有如下圖所示：
瀏覽器驗證了該CA機構的有效性。
打開證書，如下圖所示：

再次執行，驗證通過！
由此，我們了基於SSL協議的認證過程。測試類的testHttps方法模擬了一次瀏覽器的HTTPS訪問。
