当前使用版本(必填,否则不予处理)
3.3.2 (maven central latest), master SNAPSHOT version has the same issue
该问题是如何引起的？(确定最新版也有问题再提!!!)
I'm not expert in mybatis and spring-boot-test, it maybe caused by dirty cache.
重现步骤(如果有就写完整)
Just modified the official sample project, see code at https://github.com/pan3793/mybatis-plus-samples/tree/2550/mybatis-plus-sample-quickstart
clone it and switch to branch 2550, change dir to mybatis-plus-sample-quickstart, then run mvn clean test -DskipTests=false, the issue should be reproduced.
报错信息
I only paste a snippet of full stacktrace, you can follow the steps to reproduce the error.

这个是在同一个jvm线程执行了两次SpringBootTest，容器初始化了两次，但mp的方法内部源码只使用了一个静态缓存来存储类对应的表信息（含mybatis的config对象），第一次执行完成之后，缓存了表信心相关，第二次执行的时候由于缓存了数据，只切换了config，没有重新初始化resultMap，导致了以上问题。

Thx for your explanation, have a plan to fix it or no plan to support it? Other spring boot official components seems work fine in this scenario.

使用3.3.3.2-SNAPSHOT试试。

使用3.3.3.2-SNAPSHOT试试。
Before I run my test, the unit test is broken.
CacheTest > testOrder() FAILED

@pan3793 相同错误，还有更新吗， https://mvnrepository.com/artifact/com.baomidou/mybatis-plus 只支持到 3.3.2, 因为项目有多个integration test, 单独跑没问题， 放在一块就会失败。

@nieqiurong Has plan to release 3.3.3?
