# 1, 生成keystore #

#Country Name (2 letter code) [XX]:CN
    #State or Province Name (full name) []:beijing
    #Locality Name (eg, city) [Default City]:beijing
    #Organization Name (eg, company) [Default Company Ltd]:my.com
    #Organizational Unit Name (eg, section) []:devops
    #Common Name (eg, your name or your server's hostname) []:ca.my.com
    #免交互：
    keytool -genkeypair -v -alias testKey -keyalg RSA -validity 365000 -keystore test.keystore \
    -storepass 123456789 -keypass 123456789 \
    -dname "cn=my.com.web, ou=devops, o=my.com, c=CN, l=bj , st=bj "
     		   
    [wang@c7-iris2 sh]# keytool -genkeypair -v -alias testKey -keyalg RSA -validity 365000 -keystore test.keystore
     Enter keystore password:
    Keystore password is too short - must be at least 6 characters
    Enter keystore password:
    Re-enter new password:
    What is your first and last name?
      [Unknown]:  my.com
    What is the name of your organizational unit?
      [Unknown]:  devops
    What is the name of your organization?
      [Unknown]:  my.com
    What is the name of your City or Locality?
      [Unknown]:  bj
    What is the name of your State or Province?
      [Unknown]:  bj
    What is the two-letter country code for this unit?
      [Unknown]:  CN
    Is CN=my.com, OU=devops, O=my.com, L=bj, ST=bj, C=CN correct?
      [no]:  yes
    
    Generating 2,048 bit RSA key pair and self-signed certificate (SHA256withRSA) with a validity of 3,650 days
            for: CN=my.com, OU=devops, O=my.com, L=bj, ST=bj, C=CN
    Enter key password for <testKey>
            (RETURN if same as keystore password):
    Re-enter new password:
    [Storing test.keystore]
    
    Warning:
    The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an industry standard format using "keytool -importkeystore -srckeystore test.keystore -destkeystore test.keystore -deststoretype pkcs12".
    
    
    [root@cdh-c6-master aaa]# ls
    test.keystore
    [wang@c7-iris2 ~]# mkdir /usr/share/ssl
    [wang@c7-iris2 ~]# cp test.keystore /usr/share/ssl/tomcat.keystore

# 2, Tomcat 启用 HTTPS：配置server.xml #

[https://tomcat.apache.org/tomcat-8.5-doc/ssl-howto.html\#Introduction\_to\_SSL][https_tomcat.apache.org_tomcat-8.5-doc_ssl-howto.html_Introduction_to_SSL]

## a, 直接生成jks ##

[wang@c7-iris2 ~]# vi apache-tomcat-8.5.54/conf/server.xml
     <Connector port="8080" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" keystoreFile="/usr/share/ssl/tomcat.keystore" keystorePass="123456789" clientAuth="false" />

## b, 把crt证书转jks ##

#把用户证书转换成P12格式
    [root@test-c6 http-ssl]# ls
    httpd.crt  httpd.key
    [root@test-c6 http-ssl]# openssl pkcs12 -export -in httpd.crt \
       -inkey httpd.key -out keystore.p12 -passout pass:abc@123456
     
    [root@test-c6 http-ssl]# ls
    httpd.crt  httpd.key  keystore.p12
    
    
    #把p12格式文件加入到JKS格式
    [root@test-c6 http-ssl]# keytool -importkeystore -srckeystore keystore.p12 \
      -srcstoretype PKCS12 -destkeystore keystore.jks \
      -srcstorepass abc@123456 -deststorepass abc@123456
    
    Importing keystore keystore.p12 to keystore.jks...
    Entry for alias 1 successfully imported.....
    
    [root@test-c6 http-ssl]# ls
    httpd.crt  httpd.key  keystore.jks  keystore.p12

# 3, Jar包 启用 HTTPS #

## 方式1, 修改配置文件application.properties ##

[wang@c7-iris2 ~]# cat application.properties
    server.port=8088
    server.ssl.key-store=C:/tomcat.keystore
    server.ssl.keyStoreType=JKS
    server.ssl.key-store-password=123456

打完Jar 包后, 启动jar包：

## 方式2, java 启动参数添加https ##

java -Dserver.ssl.key-store=C:\tomcat-httpd-pwd8888.keystore \
    	 -Dserver.sl.keyStoreType=JKS \
    	 -Dserver.ssl.key-store-password=pwd8888 \
    	 -Djava.security.egd=file:/dev/./urandom -Djava.net.preferIPv4Stack=true  \
    	 -jar com.example.demo-0.0.1-SNAPSHOT.jar
    
    或
    java -D...同上\
    	 -cp com.example.demo-0.0.1-SNAPSHOT.jar \
    	 org.springframework.boot.loader.JarLauncher

### 拓展：java -D参数的使用 （动态修改运行时参数值） ###

#1， tomcat =======设置java -D参数值

    #2， 自定义程序=======获取java -D参数值
    package com.example.demo;
