java - 错误的休眠列类型：发现：未定义

问题描述

我在服务器（websphere）启动时遇到以下异常。VIEW_LTABLE_FULL_CLEARANCE_DAY是对 Oracle 的看法

Caused by: org.hibernate.HibernateException: Wrong column type in CALMS2CMS_SCHEMA_25.VIEW_LTABLE_FULL_CLEARANCE_DAY for column table_code. Found: undefined, expected: varchar2(255 char)

TABLE_CODE 列定义是：

TABLE_CODE  NOT NULL VARCHAR2(5 CHAR)

该列的 Hibernate 实体映射为：

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

查看定义：

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

我不明白为什么错误说Found: undefined。

映射似乎正确。

解决方案

尝试tableCode通过以下方式更正您的定义：

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

正如本文所建议的那样。
