Question

我有一个非常奇怪的问题，当我将som deps升级到项目时得到它。

我现在使用以下版本：

Spring：3.1.0.RELEASE
Hibernate：4.1.7.Final
Hsqldb：2.2.8（org.hsqldb）

我认为问题必须与文件字段有关。（Dbfile.content）

堆栈跟踪：

数据源使用类'com.mchange.v2.c3p0.ComboPooledDataSource'与驱动程序'org.hsqldb.jdbcDriver'在url'jdbc：hsqldb：mem：data'

我做错了什么？

Answer 1

问题在于 HSQLDialect 实现，它在其构造函数中注册了sql类型：

public HSQLDialect() {
    super();

    ...
    registerColumnType( Types.BLOB, "blob($l)" );
    registerColumnType( Types.CLOB, "clob($l)" );
    ...
}

$ l 取自列长度属性。但是，如果未明确设置列长度属性，则其默认值为255。在这种情况下，HSQLDialect会将列创建为 CLOB（255），这对于clobs来说很有趣......

1）

一种解决方案是使用足够的值明确设置列长度。

例如：

@Lob
@Column(length = 10000)
private String text;

但是如果你想避免使用这种人工构造，你可以修改方言。

2）

第二个解决方案是修改 HSQLDialect：

package com.extensions.dialect;

import java.sql.Types;
import org.hibernate.dialect.HSQLDialect;

public class MyHsqlDialect extends HSQLDialect {

    public MppHsqlDialect() {
        super();
        registerColumnType(Types.CLOB, "clob");
    }
}

并在hibernate配置中设置新方言：

hibernate.dialect=com.extensions.dialect.MyHsqlDialect

我在集成测试中使用此解决方案。

可在此处找到一些其他信息：

https://hibernate.atlassian.net/browse/HHH-7541

Answer 2

正确答案应该是：为@Column注释添加长度，如下所示：

@Lob
@Column(length = 10000, name = "style")
private String style;

Answer 3

我遇到过类似的问题。有很多错误：“数据异常：字符串数据，右截断”。决议是指定大字段的大小。没有该字段将限制为默认大小。但这还不是全部。 HSQL不会自动更新数据库架构。因此，更改将不适用于您重新创建数据库。

@Column(length = 5 * 1024 * 1024) // five megabytes
private byte[] bytesPreview;

Answer 4

尝试使用HSQLDB 2.2.9或最新的sanpshot，因为堆栈跟踪看起来像是在2.2.8之后修复的问题。

快照和版本的Maven存储库位于：

http://www.hsqldb.org/repos/org/hsqldb/hsqldb/

另见下面的答案。似乎使用“org.hibernate.type.MaterializedClobType”与PostgreSQL相同。但是你的字段是byte []，可以用HSQLDB更好地表示为BLOB。

Retrieve image from blob via Hibernate (not JDBC)

Answer 5

当我的一个关系属性缺少@ManyToOne注释时，我得到了相同的错误消息。将HSQLDB升级到2.2.9并没有解决问题。

JPA 2有此要求：

“关系最低限度也需要关系注释 @OneToMany或@ManyToMany“

您是否在未添加此类注释的情况下添加了新属性？

带有HSQLDB的Hibernate 4.1提供'数据异常：字符串数据，右截断'
