补充说明

针对一些常用的接口，ShardingSphere 提供了语法糖，可以简化操作，目前已提供的插件查询语法糖如下：

• 查询 org.apache.shardingsphere.sharding.spi.ShardingAlgorithm 接口实现：SHOW SHARDING ALGORITHM PLUGINS
• 查询 org.apache.shardingsphere.infra.algorithm.loadbalancer.core.LoadBalanceAlgorithm 接口实现：SHOW LOAD BALANCE ALGORITHM PLUGINS
• 查询 org.apache.shardingsphere.encrypt.spi.EncryptAlgorithm 接口实现：SHOW ENCRYPT ALGORITHM PLUGINS
• 查询 org.apache.shardingsphere.mask.spi.MaskAlgorithm 接口实现：SHOW MASK ALGORITHM PLUGINS
• 查询 org.apache.shardingsphere.shadow.spi.ShadowAlgorithm 接口实现：SHOW SHADOW ALGORITHM PLUGINS
• 查询 org.apache.shardingsphere.keygen.core.algorithm.KeyGenerateAlgorithm 接口实现：SHOW KEY GENERATE ALGORITHM PLUGINS
