我正在使用 springs SimpleJdbcInsert 来执行 JDBC 插入返回 2 个自动生成的键。

我使用的命令是:

KeyHolder keys = insert.withTableName("TRANSACTION").usingGeneratedKeyColumns("TRANSACTIONID", "ROWID").executeAndReturnKeyHolder(params);

keys只包含一个名为SCOPE_IDENTITY()

日志似乎表明事情进展顺利,除了 TRANSACTIONID 和 ROWID 的自动生成的键没有被填充,这里有一些相关的日志

这是我正在使用的 H2 数据库的问题。它不支持返回多个自动生成的密钥。

尝试这个。

这是一个完整的保存方法,它使用两个属性集保存 companyCarrier 对象。这些属性的数据类型为 Integer 和 String。

然后在 companyCarrier 对象的 id 属性上设置生成的密钥。

Object[] args = { companyCarrier.getCompanyId(),
            companyCarrier.getCarrierId() };
    Class<?>[] parameterTypes = { CompanyCarrier.class };
    int[] types = { Types.INTEGER, Types.VARCHAR };

    SqlUpdate su = new SqlUpdate();

    su.setJdbcTemplate(getJdbcTemplate());

    su.setSql(getSqlQuery(getClass(), "save", parameterTypes));

    setSqlTypes(su, types);

    su.setReturnGeneratedKeys(true);
    su.compile();

    KeyHolder keyHolder = new GeneratedKeyHolder();
    su.update(args, keyHolder);
    int id = keyHolder.getKey().intValue();

    if (su.isReturnGeneratedKeys()) {
        companyCarrier.setId(id);
    } else {
        throw new RuntimeException("No key generated for insert statement");
    }
