spring boot 2.1.1,@Transactional注释无法启动事务回滚

Question

@Transactional
public BooleanMessage importUserOne(String ppUserId) {

    deleteOneUser(ppUserId);
    transferOneUser(ppUserId);

    return BooleanMessage.getSuccessMessage("同步成功！");
}

@Transactional
public void deleteOneUser(String userid) {
    try {
        // 删除：用户
        this.deleteUsers(userid);

    } catch (Exception e) {
        throw new RuntimeException("delete error : "+e.getMessage());
    }
}

public void deleteUsers(String userid) {
    dd用户Service.delete(userid);
}

public boolean delete(String ppUserId) {
    return ddMapper.deleteByPrimaryKey(ppUserId) == 1;
}


@Transactional
public void transferOneUser(String userid) {
    try {

        // 迁移：用户
        dd用户Service.transferUsers(findOne(userid));

    } catch (Exception e) {
        throw new RuntimeException("transferOneUser error : "+e.getMessage());
    }
}

@Transactional
public void transferUsers(Users one) {
    if (one == null) {
        throw new NullPointerException("Users is null!");
    }

    try {
        String userid = one.getUserid() == null ? "" : one.getUserid();


        用户 mm用户 = new 用户();
        mm用户.set用户id(userid);

        this.add(mm用户);
    } catch (Exception e) {

        throw new RuntimeException("users add error : "+e.getMessage());
    }
}

public boolean add(用户 mm用户) {
    return ddMapper.insert(mm用户) == 1;
}

import org.springframework.context.annotation.ComponentScan;

@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class,DataSourceTransactionManagerAutoConfiguration.class, MybatisAutoConfiguration.class})
@SpringBootApplication
@ComponentScan(basePackages={"importdata.*"})
public class BshImportdataApplication {

    public static void main(String[] args) {
        SpringApplication.run(BshImportdataApplication.class, args);
    }
}

```我在spring boot 2.1.1版本中，在service层中的方法上加上@Transactional的注解，
没办法启动这个方法的事务回滚，里面的方法执行一半出错也不会回滚成没执行之前的一样，求大神解决
