SpringBoot中整合Sharding Sphere实现数据加解密/数据脱敏/数据库密文，查询明文

**Spring Boot 中整合 ShardingSphere 实现数据加解密、数据脱敏和数据库密文**

在大型分布式系统中，数据安全性和隐私保护是非常重要的。ShardingSphere 是一个开源的 Java 分布式数据库中间件，提供了数据分片、读写分离、全局事务等功能。在本文中，我们将介绍如何使用 Spring Boot 整合 ShardingSphere 实现数据加解密、数据脱敏和数据库密文。

###1.依赖配置首先，我们需要在 `pom.xml` 文件中添加必要的依赖：

xml<dependencies>
