休眠列类型错误:找到:未定义

Question

我在服务器(websphere(启动时得到以下异常。VIEW_LTABLE_FULL_CLEARANCE_DAY是对Oracle 的一种看法

TABLE_CODE列定义为：

TABLE_CODE  NOT NULL VARCHAR2(5 CHAR)

该列的Hibernate实体映射为：

@Column(name = "table_code")
private String tableCode;

视图定义：

CREATE OR REPLACE FORCE VIEW VIEW_LTABLE_FULL_CLEARANCE_DAY (
  TABLE_TYPE,
  TABLE_CODE,
  TABLE_TERRITORY_CODE,
  DESCRIPTION,
  FULL_CLEARANCE_DAYS,
  RECEIPT_REQUIRED
) AS
SELECT
   TYPE AS TABLE_TYPE,
   CODE AS TABLE_CODE,
   TERRITORY_CODE AS TABLE_TERRITORY_CODE,
   DESCRIPTION,
   FULL_CLEARANCE_DAYS,
   RECEIPT_REQUIRED
FROM PAYMENT

我不明白的是为什么错误显示Found: undefined。

映射似乎是正确的。

Answer 1

尝试以以下方式更正tableCode定义：

@Column(name = "table_code", columnDefinition = "VARCHAR2(5 CHAR)")
private String tableCode;

正如本文中所建议的。

Answer 2

好的，当我重新创建视图时，错误就会消失。但我仍然不知道为什么我一直收到最初的错误消息。
