问题重现

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-seata</artifactId>
    <version>2.1.0.RELEASE</version>    
</dependency>

2.1.0.RELEASE默认导入了0.7.1的seata-all,通过mybatis-plus的saveBatch()保存数据时，存在正常事务出错回滚的现象。

修改saveBatch()为foreach遍历+insert()方法，提交时爆java.nio.BufferOverflowException，暂未解决

解决

修改seata-all版本

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-seata</artifactId>
    <version>2.1.0.RELEASE</version>
    <exclusions>
        <exclusion>
            <groupId>io.seata</groupId>
            <artifactId>seata-all</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>io.seata</groupId>
    <artifactId>seata-all</artifactId>
    <version>0.9.0</version>
</dependency>

seata-server版本要与seata-all对应
