java京东云密钥管理服务使用

前段时间项目中使用到了加密，学习使用了下京东云密钥管理服务。这里记录下，方便今后学习使用
登录京东云官网

获取accessKeyId和secretAccessKey在另一篇博客中写过，可以查看下：
获取accessKeyId和secretAccessKey

创建一个密钥

密钥id一会会使用到,这里选择的是 华北-北京

前期准备好了。就开始上代码

引入pom

<!--京东云加密-->
<dependency>
    <groupId>com.jdcloud.sdk</groupId>
    <artifactId>kms</artifactId>
    <version>0.3.0</version>
</dependency>

application.properties

jd.kms.accessKeyId=京东云账号id

测试

这里是使用knife4j。这里介绍knife4j使用

加密

解密

控制台

测试OK！

欢迎大神指导,可以留言交流!
