通过Middlegen生成hbm文件和java代码

本文所用数据库版本为MySQL5.0.15、Oracle10G、MSSQLServer2000。

第一步:准备工作

下载Middlegen-Hibernate-r5hibernate-extensions-2.1.3,并解压至项目的lib目录下。把数据库驱动拷贝至“Middlegen-Hibernate-r5/lib”目录下。

第二步:配置MiddlenGen所需要的目标数据库参数

修改在“Middlegen-Hibernate-r5/config/database”目录下的配置文件。

1、  Hibernate+MySQL配置

   <property name="database.script.file"          value="${src.dir}/sql/${name}-mysql.sql"/>

   <property name="database.driver.file"          value="${lib.dir}/mysql-connector-java-3.1.12-bin.jar"/>

   <property name="database.driver.classpath"     value="${database.driver.file}"/>

   <property name="database.driver"               value="org.gjt.mm.mysql.Driver"/>

   <property name="database.url"                  value="jdbc:mysql://localhost/sample"/>

   <property name="database.userid"               value="root"/>

   <property name="database.password"             value="root"/>

   <property name="database.schema"               value=""/>

   <property name="database.catalog"              value=""/>

 

   <property name="jboss.datasource.mapping"      value="mySQL"/>

2、  Hibernate+Oracle10G配置

   <property name="database.script.file"          value="${src.dir}/sql/${name}-oracle.sql"/>

   <property name="database.driver.file"          value="${lib.dir}/ojdbc14.jar"/>

   <property name="database.driver.classpath"     value="${database.driver.file}"/>

   <property name="database.driver"               value="oracle.jdbc.driver.OracleDriver"/>

   <property name="database.url"                  value="jdbc:oracle:thin:@localhost:1521:orcl"/>

   <property name="database.userid"               value="SAMPLE"/>

   <property name="database.password"             value="SAMPLE"/>

   <property name="database.schema"               value="SAMPLE"/><!—注意此处一定要配置schema-->

   <property name="database.catalog"              value=""/>

 

   <property name="jboss.datasource.mapping"      value="Oracle10g"/>

3、  Hibernate+MSSQLServer2000配置

   <property name="database.script.file"           value=""/>

   <property name="database.driver.file"           value="${lib.dir}/mssqlserver.jar"/>

   <property name="database.driver"                value="com.microsoft.jdbc.sqlserver.SQLServerDriver"/>

   <property name="database.url"                   value="jdbc:microsoft:sqlserver://localhost:1433;database=sample"/>

   <property name="database.userid"                value="sample"/>

   <property name="database.password"              value="sample"/>

   <property name="database.schema"                value="dbo"/><!—注意此处一定要配置schema,且要设置为dbo-->

   <property name="database.catalog"               value="sample"/><!—注意此处一定要配置catalog -->

 

   <property name="jboss.datasource.mapping"       value="MS SQLSERVER2000"/>

另外一种使用JTDS驱动连接SQLServer2000的配置

<property name="database.script.file"            value=""/>

   <property name="database.driver.file"          value="${lib.dir}/jtds-1.2.5.jar"/>

   <property name="database.driver"               value="net.sourceforge.jtds.jdbc.Driver"/>

   <property name="database.url"                   value="jdbc:jtds:sqlserver://localhost:1433/sample"/>

   <property name="database.userid"               value="sample"/>

   <property name="database.password"             value="sample"/>

   <property name="database.schema"               value="dbo"/>

   <property name="database.catalog"              value="sample"/>

 

   <property name="jboss.datasource.mapping"      value="MS SQLSERVER2000"/>

 

第三步:修改Middlegenbuild.xml

修改“Middlegen-Hibernate-r5根目录下的build.xml文件。

Hibernate2修改如下:

<?xml version="1.0"?>

<!DOCTYPE project [

    <!ENTITY database SYSTEM "file:./config/database/mysql.xml"><!—此处修改为对应xml文件-->

]>

<project name="Middlegen Hibernate" default="all" basedir=".">

<!-- project name="Middlegen Hibernate" default="all" basedir="." -->

   <property file="${basedir}/build.properties"/>

   <property name="name" value="HibernateSample"/><!—此处修改为期望的Application Name-->

   <!-- This was added because we were several people (in a course) deploying to same app server>

   <property environment="env"/>

   <property name="unique.name"               value="${name}.${env.COMPUTERNAME}"/-->

   <property name="gui"                       value="true"/>

   <property name="unique.name"               value="${name}"/>

   <property name="appxml.src.file"           value="${basedir}/src/application.xml"/>

   <property name="lib.dir"                   value="${basedir}/lib"/>

   <property name="src.dir"                   value="${basedir}/src"/>

   <property name="java.src.dir"              value="${src.dir}/java"/>

   <property name="web.src.dir"               value="${src.dir}/web"/>

   <property name="build.dir"                 value="${basedir}/build"/>

   <property name="build.java.dir"            value="${build.dir}/java"/>

   <property name="build.gen-src.dir"         value="../../src"/><!—此处修改为期望的输出目录-->

   <property name="build.classes.dir"         value="${build.dir}/classes"/>

   ............

   <!-- =================================================================== -->

   <!-- Run Middlegen                                                       -->

   <!-- =================================================================== -->

   <target

      name="middlegen"

   >

      <mkdir dir="${build.gen-src.dir}"/>

      <echo message="Class path = ${basedir}"/>

      <taskdef

         name="middlegen"

         classname="middlegen.MiddlegenTask"

         classpathref="lib.class.path"

      />

      <middlegen

         providerURL="${java.naming.provider.url}"

         datasourceJNDIName="${datasource.jndi.name}"

         driver="${database.driver}"

         username="${database.userid}"

         password="${database.password}"

         schema="${database.schema}"

         catalog="${database.catalog}"

      >

      ............

         <!—此处修改为期望的包名,设置为包含XDocletTag -->

         <hibernate

            destination="${build.gen-src.dir}"

            package="org.redsaga.quickstart"

            genXDocletTags="true"

            genIntergratedCompositeKeys="false"

            javaTypeMapper="middlegen.plugins.hibernate.HibernateJavaTypeMapper"

         />

      </middlegen>

      <mkdir dir="${build.classes.dir}"/>

   </target>

   ............

</project>

Hibernate3的设置与修改:

首先修改“Middlegen-Hibernate-r5/middlegen-lib”目录下的middlegen-hibernate-plugin-2.1.jar内的“middlegen/plugins/hibernate/”包路径下的hibernate.vm文件,把

<!DOCTYPE hibernate-mapping PUBLIC

    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

改为:

<!DOCTYPE hibernate-mapping PUBLIC

    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

通过网址:http://sourceforge.net/projects/jboss/files/JBossTools/JBossTools3.0.0.x/HibernateTools-3.2.4.GA-R200903141626-H5.zip/download,下载Hibernate Tools

下载后获取“plugins/org.hibernate.eclipse_3.2.4.GA-R200903141626-H5/lib/tools”下的freemarker.jarhibernate-tools.jar,拷贝到“Middlegen-Hibernate-r5/lib”目录下。

获取“”目录下的dom4j-1.6.1.jarhibernate3.jar拷贝到“Middlegen-Hibernate-r5/lib”目录下。

从网站“http://www.slf4j.org/“上获取slf4j-api-1.5.8.jarslf4j-jdk14-1.5.8.jar,拷贝到“Middlegen-Hibernate-r5/lib”目录下。

修改build.xml文件

<!DOCTYPE project [

    <!ENTITY database SYSTEM "file:./config/database/mysql.xml"><!—此处修改为对应xml文件-->

]>

   ............

   <property name="name" value="HibernateSample"/><!—此处修改为期望的Application Name-->

 

   <!-- This was added because we were several people (in a course) deploying to same app server>

   <property environment="env"/>

   <property name="unique.name"               value="${name}.${env.COMPUTERNAME}"/-->

   <property name="gui"                       value="true"/>

   <property name="unique.name"               value="${name}"/>

   <property name="appxml.src.file"           value="${basedir}/src/application.xml"/>

   <property name="lib.dir"                   value="${basedir}/lib"/>

   <property name="src.dir"                   value="${basedir}/src"/>

   <property name="java.src.dir"              value="${src.dir}/java"/>

   <property name="web.src.dir"               value="${src.dir}/web"/>

   <property name="build.dir"                 value="${basedir}/build"/>

   <property name="build.java.dir"            value="${build.dir}/java"/>

   <property name="build.gen-src.dir"         value="../../src"/><!—此处修改为期望的输出目录-->

   <property name="build.classes.dir"         value="${build.dir}/classes"/>

  ............

   <target

      name="middlegen"

      description="Run Middlegen"

      unless="middlegen.skip"

      depends="init,fail-if-no-xdoclet-1.2,check-driver-present,panic-if-driver-not-present"

   >

      <mkdir dir="${build.gen-src.dir}"/>

      <echo message="Class path = ${basedir}"/>

      <taskdef

         name="middlegen"

         classname="middlegen.MiddlegenTask"

         classpathref="lib.class.path"

      />

      <middlegen

         appname="${name}"

         prefsdir="${src.dir}"

         gui="${gui}"

         databaseurl="${database.url}"

         initialContextFactory="${java.naming.factory.initial}"

         providerURL="${java.naming.provider.url}"

         datasourceJNDIName="${datasource.jndi.name}"

         driver="${database.driver}"

         username="${database.userid}"

         password="${database.password}"

         schema="${database.schema}"

         catalog="${database.catalog}"

      >

      ............

         <!—此处修改为期望的包名,设置为包含XDocletTag -->

         <hibernate

            destination="${build.gen-src.dir}"

            package="org.redsaga.quickstart"

            genXDocletTags="true"

            genIntergratedCompositeKeys="false"

            javaTypeMapper="middlegen.plugins.hibernate.HibernateJavaTypeMapper"

         />

      </middlegen>

      <mkdir dir="${build.classes.dir}"/>

   </target>

   ............

</project>

第四步:运行build.xml

运行build.xml后出现如下界面:

通过Middlegen生成hbm文件和java代码_第1张图片

 

 

修改Key generator的方式,点击“Generate”按钮,生成.hbm.xml文件。Hibernate2Hibernate3生成的文件dtd版本不一样。

第五步:修改Middlegenbuild.xml中的pathhbm2java设置

Hibernate2配置如下:

   <path id="lib.class.path">

      <pathelement path="${database.driver.classpath}"/>

      <fileset dir="${lib.dir}">

         <include name="*.jar"/>

      </fileset>

      <!-- The middlegen jars -->

      <!--fileset dir="${basedir}/.."-->

      <fileset dir="${basedir}/middlegen-lib">

         <include name="*.jar"/>

      </fileset>

      <!—增加HibernateHibernate-extensions的类包-->

<pathelement path="../hibernate-2.1/hibernate2.jar"/>

     <fileset dir="../hibernate-2.1/lib">

       <include name="*.jar"/>

     </fileset>

     <pathelement path="../hibernate-extensions-2.1.3/tools/hibernate-tools.jar"/>

     <fileset dir="../hibernate-extensions-2.1.3/tools/lib">

        <include name="*.jar"/>

     </fileset>

   </path>

Hibernate3配置如下(由于将Hibernate ToolsHibernate3jar包拷贝到了lib下,path路径不再需要修改,“Hibernate-extensions“也不再需要。

<target name="hbm2java" description="Generate .java from .hbm files.">

      <taskdef

         name="hbm2java"

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

         classpathref="lib.class.path"

      />

       <hbm2java destdir="${build.gen-src.dir}">

       <configuration>

           <fileset dir="${build.gen-src.dir}">

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

           </fileset>

       </configuration>

       <hbm2java jdk5="true" />

    </hbm2java>

   </target>

 

第六步:在控制台build.xml目录下,运行“ant hbm2java”命令。生成Java代码。
