如何在没有ArrayIndexOutOfBoundsException的情况下通过executeBatch获取生成的密钥？

Question

以下方法我想同时插入几个记录.

public void insert() {
    try {
        this.connection.setAutoCommit(false);
        PreparedStatement ps = this.connection.prepareStatement(
                "INSERT INTO  COMPANY (NAME,Address) Values (?,?)", new String[]{"ID"});
        ps.setString(1, "X01");
        ps.setString(2, "Address1");
        ps.addBatch();

        ps.setString(1, "Y01");
        ps.setString(2, "Address2");
        ps.addBatch();

       //EXCEPTION OCCURS HERE
        int[] numUpdates = ps.executeBatch();

        for (int i = 0; i < numUpdates.length; i++) {
                System.out.println("Execution " + i +
                        "successful: " + numUpdates[i] + " rows inserted");
        }

        ResultSet resultSet =
                (ps).getGeneratedKeys();
        while (resultSet.next()) {
            String deptNoKey = resultSet.getString(1);
            System.out.println("Automatically generated key value = "
                    + deptNoKey);
        }
    } catch (BatchUpdateException b) {
        // process BatchUpdateException
    } catch (SQLException e) {
        e.printStackTrace();
    }

}

此时,当我希望得到为每个INSERT生成的PK时,我得到了这个例外

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 22

异常后:在表COMPANY中,正确添加了两个记录,但我希望每个插入执行一个ResultSet,因此我可以生成每个PK.

这似乎是Windows上的Oracle,驱动程序JAR ojdbc6.jar或(知道Oracle)两者中的错误.

您提供的代码没有重大问题.它应该工作,虽然当我运行它时,每次插入的行数返回为-2(= Statement.SUCCESS_NO_INFO),所以你可能最好忽略这些数字.

使用Oracle JDBC驱动程序JAR的四个版本,在Linux上使用Oracle 11g XE 11.2.0.2.0,您的代码运行正常.但是,如果我在具有相同版本的Oracle XE和ojdbc6.jar的Windows 10上运行它,它将失败,并获得相同的ArrayIndexOutOfBoundsException.如果我使用ojdbc7.jar而不是ojdbc6.jar,问题就会消失.

因此,我建议用ojdbc7.jar替换ojdbc6.jar,你可以从这里下载.
