Query result discrepancy

[SumStar93]

When multiple (dozens) of queries are executed simultaneously, there is an occurrence where a different query result is returned for a specific query. For example, let's say there are query A and query B, and their respective results should be result A and result B, but the following combinations of results are returned:
query A: result B
query B: result A

The version and other information provided are as follows:

Version: '2.2.0'
Implementation group: 'org.mybatis.spring.boot'
Name: 'mybatis-spring-boot-starter'
Currently, to avoid such issues, we are using 'flushCache=true'.

Hello @SumStar93 ,

It sounds like you are sharing some object that is not thread safe between multiple threads.
There are some general advices in the following page.

If your project is relatively simple and can be shared publicly on your GitHub repo, I would take a look when I have some time.
