在Hibernate有一些相当方便的辅助工具: hbm2java,hbm2ddl, 数据库的逆向工程,Mapping Editor.

这些任务可以通过Ant构建完成,Hibernate提供了Ant Tasks及其构建脚本.由于Hibernate从2到3进行了重大重构,且包重新做了组织,因此Ant构建脚本也发生了巨大变化.在2中脚本样式为:

<?xml version="1.0"?

<project name="anto builder"

default="db" basedir="."

<!-- Set up properties containing important project directories --

<property name="source.root" value="src"/

<property name="class.root" value="classes"/

<property name="lib.dir" value="lib"/

<property name="data.dir" value="data"/

<!-- Set up the class path for compilation and execution --

<path id="project.class.path"

<!-- Include our own classes, of course --

<pathelement location="${class.root}" /

<!-- Include jars in the project library directory --

<fileset dir="${lib.dir}"

<include name="*.jar"/

</fileset

</path

<target name="db" description="Runs HSQLDB database management UIagainst the database file--use when application is not running"

<java classname="org.hsqldb.util.DatabaseManager"

fork="yes"

<classpath refid="project.class.path"/

<arg value="-driver"/

<arg value="org.hsqldb.jdbcDriver"/

<arg value="-url"/

<arg value="jdbc:hsqldb:${data.dir}/music"/

<arg value="-user"/

<arg value="sa"/

</java

</target

<!-- Teach Ant how to use Hibernate's code generation tool --

<taskdef name="hbm2java"

classname="net.sf.hibernate.tool.hbm2java.Hbm2JavaTask"

classpathref="project.class.path"/

<!-- Generate the java code for all mapping files in our source tree --

<target name="codegen"

description="Generate Java source from the O/R mapping files"

<hbm2java output="${source.root}"

<fileset dir="${source.root}"

<include name="**/*.hbm.xml"/

</fileset

</hbm2java

</target

<!-- Create our runtime subdirectories and copy resources into them --

<target name="prepare" description="Sets up build structures"

<mkdir dir="${class.root}"/

<!-- Copy our property files and O/R mappings for use at runtime --

<copy todir="${class.root}"

<fileset dir="${source.root}"

<include name="**/*.properties"/

<include name="**/*.hbm.xml"/

</fileset

</copy

</target

<!-- Compile the java source of the project --

<target name="compile" depends="prepare"

description="Compiles all Java classes"

<javac srcdir="${source.root}"

destdir="${class.root}"

debug="on"

optimize="off"

deprecation="on"

<classpath refid="project.class.path"/

</javac

</target

<!-- Generate the schemas for all mapping files in our class tree --

<target name="schema" depends="compile"

description="Generate DB schema from the O/R mapping files"

<!-- Teach Ant how to use Hibernate's schema generation tool --

<taskdef name="schemaexport"

classname="net.sf.hibernate.tool.hbm2ddl.SchemaExportTask"

classpathref="project.class.path"/

<schemaexport properties="${class.root}/hibernate.properties"

quiet="no" text="no" drop="no"

<fileset dir="${class.root}"

<include name="**/*.hbm.xml"/

</fileset

</schemaexport

</target

</project

在3中,构建脚本为:

<?xml version="1.0" encoding="GBK"?

<project name="Hibernate" default="anthbm2java" basedir="."

<property name="src.dir" value="./src" /

<property name="class.dir" value="./bin" /

<property name="lib.dir" value="D:/eclipse/plugins/org.hibernate.eclipse_3.0.0.alpha4/lib" /

<path id="project.class.path"

<fileset dir="${lib.dir}"

<include name="*.jar"/

</fileset

<pathelement location="${class.dir}" /

</path

<path id="tasks.classpath"

<fileset dir="${lib.dir}"

<include name="*.jar"/

</fileset

<pathelement location="${class.dir}" /

</path

<target name="anthbm2java"

<taskdef name="hibernatetool"

classname="org.hibernate.tool.ant.HibernateToolTask"

classpathref="tasks.classpath"/

<hibernatetool destdir="${class.dir}"

<configuration configurationfile="hibernate.cfg.xml"

<fileset dir="${src.dir}"

<include name="**/*.hbm.xml" /

</fileset

</configuration

<hbm2ddl export="false" console="false" create="true" update="false" drop="false" outputfilename="broad.sql" delimeter=";"/

其中的delimeter属性在Hibernate-Tool 3 A5版本中不支持.

<hbm2java generics="true" ejb3="false"/

<cfg2hbm/

<hbm2doc/

<!--

<cfg2cfgXml/

这个任务在Hibernate-Tool 3 A5版本中不支持.

--

</hibernatetool

</target

</project Hibernate3构建脚本的变化

这个脚本在Eclipse中检验过.

通过这个脚本,执行了很多Hibernate辅助工具的功能,方便了开发.
