Sqlite& Hibernate Ex：否JDBC类型的Dialect映射：0

我使用自定义方言（ https://code.google.com/p/hibernate -sqlite / ）用于连接Sqlite和Hibernate。因为Hibernate并没有完全支持Sqlite。

Im using a custom dialect( https://code.google.com/p/hibernate-sqlite/ ) for connect Sqlite with Hibernate. Because Hibernate doesnt full support Sqlite yet.

如果我不添加以下行到 SqliteDialect ， query.list（）抛出 MappingException

If i don't add following lines to SqliteDialect, query.list() throwing MappingException

registerColumnType(Types.NULL, "null");
registerHibernateType(Types.NULL, "null");

我将 nullable = true 添加到我的实体@Column。

I added nullable = true to my Entity @Column.

目前看起来不错，但是如果这个列有一个 null 值，当我调用 query.list（），它会抛出 NullPointerException 。

That currently looking good but if this column have a null value and When i called query.list(), it throws NullPointerException.

我解决这个问题。我错过了什么？谢谢！

How could I resolve this. What am I missing? Thank you in advance!
