spring - 带有 HSQLDB 的 Hibernate 4.1 给出 'data exception: string data, right truncation'

我有一个很奇怪的问题，当我将 som deps 升级到项目时遇到了。

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)

我认为问题与文件字段有关。 (Dbfile.content)

堆栈跟踪:

GenericDaoJpa.java

        this.entityManager = entityManager;
    }

    public GenericDaoJpa(Class<T> type) {
        super();
        this.type = type;
    }

    @Transactional(readOnly = true)
    public T get(Long id) {
        if (id == null) {
            return null;
        } else {
            return entityManager.find(type, id);
        }
    }

    @SuppressWarnings("unchecked")
    @Transactional(readOnly = true)
    public List<T> getAll() {
        return entityManager.createQuery("select o from " + type.getName() + " o").getResultList();
    }

    @Transactional(readOnly = false)
    public T save(T object) {
        if (object.getId() != null) {
            return entityManager.merge(object);
        } else {
            entityManager.persist(object);
        }
        entityManager.flush();
        return object;
    }

    public T delete(T object) {
        entityManager.remove(object);
        return object;
    }
}

它失败了:'cvDao.save(cv).getId();'

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

我做错了什么？

最佳答案

问题在于 HSQLDialect 实现，它在其构造函数中注册 sql 类型:

public HSQLDialect() {
    super();

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

$l 取自列长度属性。但是如果没有明确设置列长度属性，那么它的默认值是 255。在这种情况下，HSQLDialect 将列创建为 CLOB(255)，这对 clobs 来说很有趣...

1)

一种解决方案是显式设置具有足够值的列长度。

例如:

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

但如果你想避免这种人为的构造，你可以修改方言。

2)

第二种解决方案是修改 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。
