Spring Cloud Config配置文件加解密

坑爹的问题

> curl http://localhost:8888/encrypt -d 123
 {"description":"No key was installed for encryption service","status":"NO_KEY"}

遇到这个问题有三个原因

1. 未配置JCE
2. 未设置key/keystore
3. spring cloud bug

如何解决

覆盖JCE

JDK6的下载地址：
http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html

JDK7的下载地址：
http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

JDK8的下载地址：
http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

下载后，加压文件，把local_policy.jar,US_export_policy.jar拷贝并覆盖到$JAVA_HOME/jre/lib/security

设置key/keystore

设置key

在application.properties设置对应的key

encrypt.key=mykey

设置keystore

生成keystore

$ keytool -genkeypair -alias mytestkey -keyalg RSA \
  -dname "CN=Web Server,OU=Unit,O=Organization,L=City,S=State,C=US" \
  -keypass changeme -keystore server.jks -storepass letmein

修改application.yml

encrypt:
  keyStore:
    location: classpath:/server.jks
    password: letmein
    alias: mytestkey
    secret: changeme

spring cloud bug

Dalston.SR3、Dalston.SR2版本不能对配置文件加密，若需要调整到Dalston.SR1或者期待Dalston.SR4的发布

配置加解密

若能解决以上的问题，那可以试试，哈哈哈~~~

ps：由于小编的项目与你的配置有些偏差（如context=path,密钥对），结果也会有些偏差
