Mybatis scriptRunner无法回滚

Question

使用scriptrunner运行sql文件，当发生错误时，我希望sql可以回滚，但是失败。
请帮助我。

Java代码：

try {
    Class.forName(driver);
    conn = DriverManager.getConnection(url, userName, password);
    conn.setAutoCommit(false);
    ScriptRunner runner = new ScriptRunner(conn);
    runner.setAutoCommit(false);
    runner.setStopOnError(true);
    runner.setSendFullScript(false);
    runner.setDelimiter(";");
    runner.setFullLineDelimiter(false);
    runner.setLogWriter(null);

    Resource resource = new ClassPathResource(sqlFileName);
    File file = resource.getFile();
    runner.runScript(new InputStreamReader(new FileInputStream(file), StandardCharsets.UTF_8));

    conn.commit();
} catch (Exception e) {
    conn.rollback();
    error = e;
} finally {
    close(conn);
}

sql文件：

create table daiql_test2 (
    id int,
    name varchar(100)
);

insert into daiql_test2 (id, name) value (1, 'test1');
update daiql_test2 set name = 'test2' where id = 1;

gold bless no bug...;

我使用的是mysql数据库，但它不起作用，因此作为oracle ...
DDL不仅无法回滚，而且DML也无法回滚。
这里有一些代码错误吗？

MySQL版本：

select version();

5.7.20

引擎：

show table status where name= 'daiql_test2';

Name    Engine  Version Row_format  Rows    Avg_row_length  Data_length Max_data_length Index_length    Data_free   Auto_increment  Create_time Update_time
