java - JOOQ 按问题排序

Question

当我使用 Record13 或更多 orderBy() 方法时显示错误

orderBy(org.jooq.SortField<T1>) in SelectOrderByStep cannot be applied to 
orderBy(org.jooq.SortField<java.sql.Timestamp>)

使用 Record12 或更低版本一切正常。

Record14 的代码有错误:

public Result<Record14<Integer, Timestamp, OperationType, Integer, Integer, String, String, String,
            Integer, String, String, Integer, String, String>> getOperationsHistory(int ownerId, Timestamp fromDate, Timestamp toDate, Integer outletId, Integer merchantId){
        Condition condition = OPERATION.TIMESTAMPEVENT.between(fromDate, toDate)
        .and(OUTLET.OWNERID.eq(ownerId));
        if (outletId != null) {
            condition = condition.and(OPERATION.OUTLETID.eq(outletId));
        }
        if (merchantId != null) {
            condition = condition.and(OPERATION.MERCHANTID.eq(merchantId));
        }
        Select<Record14<Integer, Timestamp, OperationType, Integer, Integer,
                String, String, String, Integer, String, String, Integer, String, String>> select =
                db.select(OPERATION.ID, OPERATION.TIMESTAMPEVENT, OPERATION.TYPE, OPERATION.AMOUNT, OPERATION.CREDITS, MERCHANT.NAME,
                        CLIENT.PHONE, CLIENT.PUBLICID, CLIENT.ID, CLIENT.NAME, CLIENT.AVATARURL, RECEIPT.PRINTEDNO, OFFER.TITLE, OFFER.TYPE)
                .from(OPERATION.leftOuterJoin(CLIENT).on(OPERATION.CLIENTID.eq(CLIENT.ID))
                        .leftOuterJoin(MERCHANT).on(OPERATION.MERCHANTID.eq(MERCHANT.ID))
                        .leftOuterJoin(OUTLET).on(OPERATION.OUTLETID.eq(OUTLET.ID))
                        .leftOuterJoin(RECEIPT).on(OPERATION.RECEIPTID.eq(RECEIPT.ID))
                        .leftOuterJoin(OFFER).on(OPERATION.OFFERID.eq(OFFER.ID)))
                .where(condition).orderBy(OPERATION.TIMESTAMPEVENT.desc());
        return select.fetch();
    }

如何解决这个问题？

Answer 1

根据您的评论，我认为您没有使用最新版本的 JDK:1.8.0_45。最近，Java 编译器修复了很多错误。 The latest release of the Oracle JDK is version 1.8.0_60 .

jOOQ 大量使用:

• 重载
• 泛型
• 可变参数

在 Java 8 中，类型推断已被大幅修改以支持 lambda 表达式和 generalized target-type inference 。这些修改是早期 JDK 8 版本中出现错误的原因。

我建议升级。
