Liferay 之 二 增删改查
1. Liferay 连接MySQL数据库, 创建配置文件
? 1.1 文件名: portal-ext.properties
? 1.2 文件路径: Liferay bundle 根目录
? 1.3 内容
jdbc.default.driverClassName=com.mysql.jdbc.Driverjdbc.default.url=jdbc:mysql://localhost:3306/lportal?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=falsejdbc.default.username=rootjdbc.default.password=123456
?
2. 使用Service Builder生成数据基本操作的代码
? 2.1 右键项目，选择创建Liferay Service Builder. 生成的service.xml默认路径是docroot/WEB-INF
? 2.2 service.xml 内容如下:
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 6.0.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_6_0_0.dtd"><service-builder package-path="com.project.gen"><author>juhu</author><namespace>PR</namespace><entity name="PRProduct" local-service="true" remote-service="false"><column name="productId" type="long" primary="true" /><column name="productName" type="String" /><column name="serialNumber" type="String" /><column name="companyId" type="long" /><column name="groupId" type="long" /><order by="asc"><order-column name="productName"></order-column></order><finder return-type="Collection" name="G_PN"><finder-column name="groupId" /><finder-column name="productName" /></finder><finder return-type="Collection" name="GroupId"><finder-column name="groupId" /></finder><finder return-type="Collection" name="CompanyId"><finder-column name="companyId" /></finder></entity></service-builder>
?? 2.3 运行service.xml文件。 右键Liferay/build service
?? 2.4 A lot of code will be generated including model code, service code, table sql etc. For the generated code, what we should focus on is com/project/gen/service/impl/xxxLocalServiceImpl.java file and add the logic method here.
public class xxxLocalServiceImpl extends xxxLocalServiceBaseImpl {}?3. Create portlets.
? 3.1 Right click project to create a new portlet.
? 3.2
