?? 我寫(xiě)的這些只是Hibernate的一些基本的使用方法，如果你不是剛剛學(xué)Hibernate的話，這篇東東不再適合你看了，呵呵。我使用的是eclipse3.2.1+myeclipse5.1.1+Firebird 2.0,Firebrid 2.0 你可以從www.Firebirdsql.org上下載到最新版本的，如果你不想用這個(gè)數(shù)據(jù)庫(kù)，你也可換成別的數(shù)據(jù)庫(kù)。
?建表語(yǔ)句：
create database 'd:\sovo.fdb' user 'SYSDBA' password 'masterkey';
create? domain d_text as blob sub_type 1;
create table Testdomain(
id Integer primary key,
name varchar(30),
context d_text
);
打開(kāi)Firebird數(shù)據(jù)庫(kù)的aliases.conf，
在里面配置: sovo = d:\sovo.fdb
在這里配置，主要是為了簡(jiǎn)化在hibernate.cfg.xml里設(shè)connection.url
