Springs SimpleJdbcInsert并不像预期的那样产生自动生成的密钥。

Question

我使用springs来执行JDBC插入和返回2自动生成的键。

我使用的命令是：

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

但是keys只包含一个名为SCOPE_IDENTITY()的密钥

日志似乎表明事情进展顺利，只是TRANSACTIONID和ROWID的自动生成密钥没有被填充，下面是一些相关的日志

Answer 1

这是我正在使用的H2数据库的一个问题。它不支持返回多个自动生成的键。

Answer 2

尝尝这个。

这是一个完整的保存方法，它保存两个属性集的companyCarrier对象。这些属性具有整数和字符串的数据类型。

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");
    }
