   > 各位大神好，我在springboot + seata1.4.2 + Dubbo2.7.x实现分库分表(3个库，t_order分4张表)的情况下，集成 + shardingSphere5.0 后，报出以下异常： Could not found any index in the table: xxx，查看了下源码，在seata1.4.2中的io.seata.rm.datasource.sql.struct.cache.MysqlTableMetaCache#resultSetMetaToSchema方法调用org.apache.shardingsphere.driver.jdbc.core.datasource.metadata.ShardingSphereDatabaseMetaData#getIndexInfo时无法获取到MetaData的主键与索引信息，最终导致seata中的(tm.getAllIndexes().isEmpty()】这行条件成立就会抛出异常，请问是什么原因，谢谢。
   
   To english：
   Springboot + Seata1.4.2 + Dubbo2.7.x + shardingSphere5.0
   
   Could not found any index in the table: XXX, looked at the source code, IO in seata1.4.2. Seata. Rm. The datasource. SQL. Struct. Cache. MysqlTableMetaCache# resultSetMetaToSchema method call org. Apache. Shardingsph Ere. Driver. JDBC. Core. The datasource. Metadata. ShardingSphereDatabaseMetaData# getIndexInfo when unable to get the primary key and index to the metadata information, If (tm.getallIndexes ().isEmpty()) is valid, an exception will be thrown.
