Spring Cloud Config是Spring Cloud一个全新的项目，依赖版本仓库（比如Git、SVN）实现分布式系统外部配置的集中管理。
文中Spring Cloud的版本是Dalston.SR4，可能在其他之后的版本有修改。
最近这段时间在学习Spring Cloud，准备在项目中使用。Spring Cloud不能简单的算是一个框架，而应该认为是一个微服务的整体解决方案，它集成了Spring Boot、Netflix等等很多非常优秀的框架，很多组件开箱即用。也正是因为它集成了这么多框架，致使其版本不够稳定，即使是SR的版本，也存在这样那样的问题。甚至有的上一个版本没有问题，这个版本就出问题了。
因为配置内容可能涉及到某些敏感信息，所以可以简单的在Spring Cloud Config中使用非对称加密实现敏感信息的安全存储。但是在使用过程中，却碰到一些奇葩的问题，无论是官方文档还是一些大神的博文，都没有明确解决。
当然，这个问题的出现与我的配置有关，很多人可能并没有碰到。这里把问题描述下，万一有人和我一样配置，也出现问题，就可以帮助别人节省点时间了。
1. 正确姿势
Spring Cloud Config的非对称加密可以使用RSA加密方式，通过JDK自带的keytool生产秘匙对，对敏感信息进行加密解密。
生产秘匙对：
keytool -genkeypair -alias mytestkey -keyalg RSA -dname "CN=Web Server,OU=China,O=www.howardliu.cn,L=Beijing,S=Beijing,C=China" -keypass changeme -keystore config-service.jks -storepass letmein
将生成的keystore文件拷贝到src/main/resources目录中，然后在配置文件bootstrap.yml中配置信息秘匙对信息：
encrypt: key-store: location: classpath:/config-service.jks alias: mytestkey password: letmein secret: changeme
在pom.xml中加入了如下配置：
<build> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> <excludes> <exclude>**/*.jks</exclude> </excludes> </resource> <resource> <directory>src/main/resources</directory> <filtering>false</filtering> <includes> <include>**/*.jks</include> </includes> </resource> </resources> </build>
然后启动应用，通过访问http://localhost:8888/encrypt/status ，返回{"status":"OK"}，说明配置正确。这个使用就可以通过访问/encrypt和decrypt两个endpoints对指定信息进行加密解密了。
这个项目的代码在https://github.com/howardliu-cn/spring-learning/tree/master/micro-service/config-service。
2. 错误姿势
刚开始学习的时候并不是如上面那样顺利，碰到了一些问题。
2.1 encrypt.key-store.*配置位置引起的加密信息未解密
最开始是将encrypt.key-store.*配置在application.yml中，这个时候通过访问http://localhost:8888/encrypt/status ，返回{"status":"OK"}。原本以为配置成功，结果在客户端获取加密信息的时候，返回的结果并没有解密，只是将{cipher}去掉了。
这个错误算是比较容易排查，Spring Cloud的主要配置文件就application.yml和bootstrap.yml两个，因为客户端中需要把Spring Cloud Config的配置信息放在bootstrap.yml中，就把encrypt.key-store.*配置bootstrap.yml试试，结果果然成功。
这个错误出现的时候，encrypt.key-store.location使用的是绝对路径file://${user.home}/work/projects/spring-learning/micro-service/config-service/src/main/resources/config-service.jks。
2.2 maven filter对keystore文件的污染
因为对Spring Cloud Config服务端定义了/info这个endpoints这个信息，需要用到maven的构建内容，所以在pom.xml中加入了filter信息：
<build> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> </resource> </resources> </build>
结果在访问 http://localhost:8888/encrypt/status 的时候，返回错误信息：
Thu Oct 12 13:55:51 CST 2017 There was an unexpected error (type=Internal Server Error, status=500). Cannot load keys from store: class path resource [config-service.jks]
服务端报错如下：
2017-10-12 13:55:50.991 ERROR 14733 --- [nio-8888-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request

从错误堆栈信息中可以看到，是秘匙对文件格式错误。但是并没有对文件进行修改，何来错误一说。本着怀疑一切的精神，重新生成了一份keystore文件，然后执行，仍然报错。
那问题就来了，文件格式没有问题，结果却报文件格式有问题，那就只能是编译的时候文件被修改了。于是将encrypt.key-store.location使用绝对路径file://${user.home}/work/projects/spring-learning/micro-service/config-service/src/main/resources/config-service.jks进行实验，结果成功解析。然后将路径改为编译后target中的文件路径，就报上面的错误。果然是maven编译的时候报错。
就在stackoverflow上找到解决方式，是maven的filter污染了文件。就把pom.xml中的配置改为这样：
<build> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> <excludes> <exclude>**/*.jks</exclude> </excludes> </resource> <resource> <directory>src/main/resources</directory> <filtering>false</filtering> <includes> <include>**/*.jks</include> </includes> </resource> </resources> </build>
再次测试，果然成功。不过遗憾的是，还不确定filter为什么会污染文件，后面慢慢研究，等找到原因再把结果放在下面。
