为什么maven搭建ssm事务不回滚？

Question

ssm往数据库增加数据时，手动加了1/0让代码报错，但还是加进去一条数据 没回滚是为什么？

@Service
public class UserServiceImpl implements UserService {
    @Autowired
    private SysUserMapper mapper;
    @Override
    public boolean saveUsers(List<SysUser> users) {
        int flag = 0;
        for (SysUser user : users) {
            flag+=mapper.insertSelective(user);
            int a = 1/0;
        }
        return flag==users.size()?true:false;
    }
}

@Test
    public void Test(){
        List<SysUser> users = new ArrayList<SysUser>();
        for (int i = 14; i < 16; i++) {
            SysUser user = new SysUser();
            user.setLoginAccount("admin"+i);
            user.setLoginPwd("admin"+i);
            user.setRealName("管理"+i);
            user.setFlag(i%2);
            users.add(user);
        }
        boolean status = service.saveUsers(users);
        Assert.assertTrue(status);
    }
