liferay持久化代码的自动生成

liferay对数据库的操作他有自已的一套写法,我们可以用service.xml来自动生成这些代码, 这样就省了不少力气.在ext-impl包的classes下面service.xml写上数据库表字段如下: 
<?xml version="1.0"?>
<!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 4.3.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_4_3_0.dtd">

<service-builder root-dir=".." package-path="com.pccw.portlet">

	<!-- ecp.ecpErp.portlet-->

	<portlet name="ecpErp" short-name="ecpErp" />

	<entity name="ecpErpEmployee" local-service="true" remote-service="true" table="Ecp_Erp_Employee"><!-- 员工表  -->

		<!-- PK fields -->

		<column name="ecpEmployeeId" type="Long" primary="true" db-name="ecpEmployeeId"/>

	    <!-- Audit fields -->
        <!-- column name这个值是要和表中的字段名一样,会自动全变成大写.  -->
	    <column name="employeeNumber" type="String"/>	
	    <column name="employeeName" type="String"/> 
	    <column name="companyCode" type="String"/>
	    <column name="departmentCode" type="String"/>
	    <column name="email" type="String"/>
	    <column name="tel" type="String"/>
	    <column name="supplierId" type="Long"/>
	    <column name="bank" type="String"/>
	    <column name="account" type="String"/>
	    <column name="orgId" type="String"/>
	    <column name="userId" type="Long"/> 
	    <column name="creater" type="String"/>
        <column name="creatTime" type="Long"/>
	    <column name="updater" type="String"/>
        <column name="updateTime" type="Long"/>
	    <column name="attribute1" type="String"/>		
	    <column name="attribute2" type="String"/>	
	    <column name="attribute3" type="String"/>	
	    <column name="attribute4" type="String"/>	
	    <column name="attribute5" type="String"/>		

		<!-- Order -->

		<order by="asc">
			<order-column name="employeeNumber" />
		</order>

		<!-- Finder methods -->	

		<finder name="userId" return-type="ecpErpEmployee" >
			<finder-column name="userId"/>	
		</finder>
		<!--增加的查找,删除的方法,默认情况下liferay会自动生成一些常用的方法,如:主键查找（findById(long id)）,查找所有(findAll()),删除（delete***(long id)）.你可以根据自已的需要来增加一些方法,包括多个字段的组合查找. -->
		<finder name="employeeName" return-type="Collection" >
			<finder-column name="employeeName"/>	
		</finder>

	</entity>


这个配置文件写好了以后,build-service这个文件,然后你就会发现在你的ext-service包中com.test.portlet.ecperp.model包下面生成三个java文件：

在com.test.portlet.ecperp.service包中生成几个java文件。
[b]ecpErpCostCenterLocalService.java：[/b] 

public interface ecpErpCostCenterLocalService {
    public java.util.List dynamicQuery(
        com.liferay.portal.kernel.dao.DynamicQueryInitializer queryInitializer)
        throws com.liferay.portal.SystemException;

    public java.util.List dynamicQuery(
        com.liferay.portal.kernel.dao.DynamicQueryInitializer queryInitializer,
        int begin, int end) throws com.liferay.portal.SystemException;
    // 增加
    public com.pccw.portlet.ecperp.model.ecpErpCostCenter createecpErpCostCenter(
        com.pccw.portlet.ecperp.model.ecpErpCostCenter account);
    // 根据主键删除	
    public com.pccw.portlet.ecperp.model.ecpErpCostCenter deleteecpErpCostCenter(
        java.lang.Long ecpAccountId) throws com.liferay.portal.SystemException;
    // 更新
    public com.pccw.portlet.ecperp.model.ecpErpCostCenter updateecpErpCostCenter(
        com.pccw.portlet.ecperp.model.ecpErpCostCenter center)
        throws com.liferay.portal.SystemException;
    // 主键查找
    public com.pccw.portlet.ecperp.model.ecpErpCostCenter findByCenterId(
        java.lang.Long centerId)
        throws com.liferay.portal.SystemException, 
            com.pccw.portlet.ecperp.NoSuchAccountException;
    // 查找所有
    public java.util.List findAll() throws com.liferay.portal.SystemException;
}


在ext-impl/classes/META-INF/ext-spring.xml配置文件中自动生成信息：

然后要修改其中的三个文件,ext-service/新建包名/service/***EntryService.java和***EntryServiceUtil.java,***EntryService.java这个是个接口,你可以把你要用到的一些持久化的方法(ext-impl/新建包名/service/***Entrypersistence.java中有所有的方法)写到这里,***EntryServiceUtil.java这里写上这些静态方法(在action中操作的时候就是调用这个类),最后一个要修改的是ext-impl/新建包名/service/impl/***EntryServiceImpl.java因为他实现了,***EntryService这个接口所以把他的实现方法写这里就好了.

以上我说的可能比较粗糙,其实自动生成这些文件后,修改那三个文件时,如果您不知道怎么改可以参照liferay的源码,他的目录层次和这个是一样的,在blog和journalArtlice里面相对应的三个文件就可以了,基本上是一看就明白了.最后一点自动生成spring.xml中bean id="com.ext.portlet.包名.service.persistence.***EntryPersistenceImpl 对应的class值,这个值每次总是个错的,不晓得为什么,要手动的改一下.
