URL: https://github.com/apache/shardingsphere/issues/26759

   version:5.3.2
   
   Debug:
   
   After the execution of the init method in 
XAShardingSphereTransactionManager, the subsequent execution will involve the 
close method. Inside the close method, the cachedDataSources.clear() operation 
will be performed.
   
   init, note the object ID @8060

   In the close method, the cachedDataSources of the object with ID @8060 is 
cleared.

   When invoking the getConnection method at this point, the cachedDataSources 
is empty.
