java - CallableStatement 抛出 org.postgresql.util.PSQLException 且日期参数未知

Question

我正在使用 CallableStatement 类来执行 Postgres 过程。但是它会抛出 PSQLException 异常。 请参阅下面的java代码和日志。

Java代码:

reCalculateBalance(null, account.getId(), DateUtils.localDateToDate(account.getDateOfInitialBalance()));

private void reCalculateBalance(BigInteger transactionId, BigInteger accountId, java.sql.Date startingDate) {
        log.info("start call sp_balance_calculation: transactionId {}, accountId {}, startingDate {}", transactionId, accountId, startingDate);
        Session session = entityManager.unwrap(Session.class);
        String result = session.doReturningWork(
                connection -> {
                    try (CallableStatement function = connection.prepareCall("call core.sp_balance_calculation(?,?,?,?)" )) {
                        if (transactionId == null) {
                            function.setNull(1, Types.BIGINT);
                        } else {
                            function.setObject(1, transactionId, Types.BIGINT);
                        }
                        if (accountId == null) {
                            function.setNull(2, Types.BIGINT);
                        } else {
                            function.setLong(2, accountId.longValue());
                        }
                        function.setDate( 3, startingDate);
                        function.registerOutParameter(4, Types.VARCHAR);
                        function.execute();
                        return function.getString( 4 );
                    }
                } );
        log.info("result  = {}", result);
        session.close();
    }

过程:sp_balance_calculation

core.sp_balance_calculation (
    IN      p_transaction_id    BIGINT,
    IN      p_account_id        BIGINT,
    IN      p_starting_date     DATE,
    INOUT   p_error_code        VARCHAR 
)

看起来日期字段转换错误，但是在查看日志时，我看到输入正常为:transactionId = null，accountId = 37，startingDate = '2020-05-27'。 请帮我检查为什么它会抛出未知的日期字段？

Answer 1

我需要设置输出参数的值。

function.setNull( 4, Types.VARCHAR);

设置此后，我能够从 java 执行程序。
