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.
