本文使用JKD1.8版本。

keytool常用命令（来自网络）

-genkey 在用户主目录中创建一个默认文件".keystore",还会产生一个mykey的别名，mykey中包含用户的公钥、私钥和证书(在没有指定生成位置的情况下,keystore会存在用户系统默认目录)

-alias 产生别名,每个keystore都关联这一个独一无二的alias，这个alias通常不区分大小写

-keystore 指定密钥库的名称(产生的各类信息将不在.keystore文件中)

-keyalg 指定密钥的算法 (如 RSA DSA（如果不指定默认采用DSA）)

-validity 指定创建的证书有效期多少天

-keysize 指定密钥长度

-storepass 指定密钥库的密码(获取keystore信息所需的密码)

-keypass 指定别名条目的密码(私钥的密码)

-dname 指定证书拥有者信息

-list 显示密钥库中的证书信息

-v显示密钥库中的证书详细信息

-export 将别名指定的证书导出到文件

-file 参数指定导出到文件的文件名

-delete 删除密钥库中某条目

-printcert 查看导出的证书信息

-keypasswd 修改密钥库中指定条目口令

-import 将已签名数字证书导入密钥库

第一步，生成siyao.jks文件

cmd进入jdk的bin目录，执行下面命令：

keytool -genkey -alias siyao -keypass 你的密码 -keyalg RSA -sigalg sha256withrsa -keysize 1024 -validity 36500 -keystore d:/siyao.jks -storepass 你的密码

执行成功后，在d盘下可以看到siyao.jks文件。

第二步，基于siyao.jks文件生成siyao.pfx(代码来自网络)

public class MyTest {public static final String PKCS12 = "PKCS12";public static final String JKS = "JKS";public static final String PFX_KEYSTORE_FILE = "d://siyao.pfx";public static final String KEYSTORE_PASSWORD = "jxnu123";public static final String JKS_KEYSTORE_FILE = "d://siyao.jks";public static void coverToPfx() {try {KeyStore inputKeyStore = KeyStore.getInstance("JKS");FileInputStream fis = new FileInputStream(JKS_KEYSTORE_FILE);char[] nPassword = null;if ((KEYSTORE_PASSWORD == null)|| KEYSTORE_PASSWORD.trim().equals("")) {nPassword = null;} else {nPassword = KEYSTORE_PASSWORD.toCharArray();}inputKeyStore.load(fis, nPassword);fis.close();KeyStore outputKeyStore = KeyStore.getInstance("PKCS12");outputKeyStore.load(null, KEYSTORE_PASSWORD.toCharArray());Enumeration enums = inputKeyStore.aliases();while (enums.hasMoreElements()) { // we are readin just one certificate.String keyAlias = (String) enums.nextElement();System.out.println("alias=[" + keyAlias + "]");if (inputKeyStore.isKeyEntry(keyAlias)) {Key key = inputKeyStore.getKey(keyAlias, nPassword);Certificate[] certChain = inputKeyStore.getCertificateChain(keyAlias);outputKeyStore.setKeyEntry(keyAlias, key, KEYSTORE_PASSWORD.toCharArray(), certChain);}}FileOutputStream out = new FileOutputStream(PFX_KEYSTORE_FILE);outputKeyStore.store(out, nPassword);out.close();} catch (Exception e) {e.printStackTrace();}}public static void main(String[] args) {coverToPfx();}

执行成功后，在d盘下可以看见siyao.pfx文件。

第三步，配置tomcat8.0.33的conf/server.xml

主要配置在<Contector port="8088"...../>这块。不通版本的tomcat配置还是有差别的，需要注意。
