middlegen r5:

i like tables being mappinged as


<hibernate-mapping>
<class
name="com.fjky.fzgs.hibernate.WsDjxx"
table="WS_DJXX"
>

<composite-id>
<key-property
name="nsrsbh"
column="NSRSBH"
type="java.lang.String"
length="20"
/>
<key-property
name="wspzxh"
column="WSPZXH"
type="java.lang.String"
length="15"
/>
</composite-id>

<property
name="wsdlDm"
type="java.lang.String"
column="WSDL_DM"
not-null="true"
length="2"
/>
<property
name="wszlDm"
type="java.lang.String"
column="WSZL_DM"
not-null="true"
length="5"
/>
<!-- associations -->
</class>
</hibernate-mapping>


it mappings like
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >

<hibernate-mapping>

<class
name="com.fjky.hibernate.SbSbxx"
table="SB_SBXX"
>

<composite-id name="comp_id" class="com.fjky.hibernate.SbSbxxPK"> ------------------------------here I don't like other class for PK --------------- how to generate as obove? thanks

<key-property
name="pzxh"
column="PZXH"
type="java.lang.String"
length="16"
/>
<key-property
name="zsxmDm"
column="ZSXM_DM"
type="java.lang.String"
length="2"
/>
</composite-id>

<property
name="nsrsbh"
type="java.lang.String"
column="NSRSBH"
not-null="true"
length="20"
/>

</class>
</hibernate-mapping>

but when I use genIntergratedCompositeKeys="true"

hbm2ddl can't work.

is there any way ?

You found the option - great.

You did not provide anywhere near enough information to answer your other question. In anycase, the DDL generated will be the same from either mapping.

for example:

create table xresource_relation (
id integer not null,
friend_id integer not null,
title varchar(30) default 'no title' not null,
note varchar(512),
primary key(id,friend_id),
foreign key(id) references xresource(id),
foreign key(friend_id) references xresource(id)
);

======================================
I set
genIntergratedCompositeKeys="true"
for generate hbm.

<taskdef
name="schemaexport"

/>

<schemaexport
properties="${build.classes.dir}/hibernate.properties"
quiet="no"
text="yes"
drop="no"
delimiter=";"
output="${build.dir}/schema-export.sql"
>
<fileset dir="${build.gen-src.dir}/com/fjky/orm">
<include name="**/*.hbm.xml"/>
</fileset>
</schemaexport>
</target>

===============================================

if I want to do hbm2ddl , must I use composite-id class not Intergrated Composite Keys ???????????

I found the reasons.
I've to override the methods equals and hashCode for composite-id.

but, middlegen r5 why not do it for us?

is there any options in the build.xml ??????????

I suppose your correct - middlegen could do that automatically for you in that mode now that hbm2java has that option. You could create a SF Bug track entry to remind me of this suggestion.

BTW: See the Middlegen web site for all (bulk) of the Ant options.
