基本步驟：

1.使用 java 創(chuàng)建一個(gè) keystore 文件
2.配置 Tomcat 以使用該 keystore 文件
3.測(cè)試
4.配置應(yīng)用以便使用 SSL ，例如 https://localhost:8443/yourApp
執(zhí)行 keytool -genkey -alias tomcat -keyalg RSA 結(jié)果如下

loiane:bin loiane$ keytool -genkey -alias tomcat -keyalg RSA
Enter keystore password:  password
Re-enter new password: password
What is your first and last name?
  [Unknown]:  Loiane Groner
What is the name of your organizational unit?
  [Unknown]:  home
What is the name of your organization?
  [Unknown]:  home
What is the name of your City or Locality?
  [Unknown]:  Sao Paulo
What is the name of your State or Province?
  [Unknown]:  SP
What is the two-letter country code for this unit?
  [Unknown]:  BR
Is CN=Loiane Groner, OU=home, O=home, L=Sao Paulo, ST=SP, C=BR correct?
  [no]:  yes
 
Enter key password for
    (RETURN if same as keystore password):  password
Re-enter new password: password

這樣就在用戶的主目錄下創(chuàng)建了一個(gè) .keystore 文件

2. 配置 Tomcat 以使用 keystore 文件

打開 server.xml 找到下面被注釋的這段

<!--
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
    maxThreads="150" scheme="https" secure="true"
    clientAuth="false" sslProtocol="TLS" />
-->

干掉注釋，并將內(nèi)容改為

<Connector SSLEnabled="true" acceptCount="100" clientAuth="false"
    disableUploadTimeout="true" enableLookups="false" maxThreads="25"
    port="8443" keystoreFile="/Users/loiane/.keystore" keystorePass="password"
    protocol="org.apache.coyote.http11.Http11NioProtocol" scheme="https"
    secure="true" sslProtocol="TLS" />

啟動(dòng) Tomcat 并訪問(wèn) https://localhost:8443. 你將看到 Tomcat 默認(rèn)的首頁(yè)。
把server.xml中8080端口的配置給注釋掉就可以。
