struts2+spring+hibernate+compass 实现全文检索
Compass是一流的开放源码JAVA搜索引擎框架，对于你的应用修饰，搜索引擎语义更具有能力。依靠顶级的Lucene搜索引擎，Compass 结合了，像 Hibernate和 Sprin的流行的框架，为你的应用提供了从数据模型和数据源同步改变的搜索力.并且添加了2方面的特征,事物管理和快速更新优化. Compass的目标是：把java应用简单集成到搜索引擎中.编码更少，查找数据更便捷。
这里struts2整合spring、hibernate就不说了。贴出compass+spring+hibernate整合的关键代码。
1、对要检索的实体进行可搜索注解：
@Searchablepublic class Product implements java.io.Serializable {@SearchableIdprivate Integer id;@SearchableProperty(name="name")private String name;@SearchableProperty(name="price")private Float price;@SearchableProperty(name="brand")private String brand;@SearchableProperty(name="description")private String description; //getter setter}package cn.changtusoft.s2sh_compass.service.impl;import org.compass.gps.CompassGps;import org.springframework.beans.factory.InitializingBean;/** * 通过quartz定时调度定时重建索引或自动随Spring ApplicationContext启动而重建索引的Builder. * 会启动后延时数秒新开线程调用compassGps.index()函数. * 默认会在Web应用每次启动时重建索引,可以设置buildIndex属性为false来禁止此功能. * 也可以不用本Builder, 编写手动调用compassGps.index()的代码. * */public class CompassIndexBuilder implements InitializingBean { // 是否需要建立索引，可被设置为false使本Builder失效. private boolean buildIndex = false; // 索引操作线程延时启动的时间，单位为秒 private int lazyTime = 10; // Compass封装 private CompassGps compassGps; // 索引线程 private Thread indexThread = new Thread() { @Override public void run() { try { Thread.sleep(lazyTime * 1000); System.out.println("begin compass index..."); long beginTime = System.currentTimeMillis(); // 重建索引. // 如果compass实体中定义的索引文件已存在，索引过程中会建立临时索引， // 索引完成后再进行覆盖. compassGps.index(); long costTime = System.currentTimeMillis() - beginTime; System.out.println("compss index finished."); System.out.println("costed " + costTime + " milliseconds"); } catch (InterruptedException e) { e.printStackTrace(); } } }; /** * 实现<code>InitializingBean</code>接口，在完成注入后调用启动索引线程. * * @see org.springframework.beans.factory.InitializingBean#afterPropertiesSet() */ public void afterPropertiesSet() throws Exception { if (buildIndex) { indexThread.setDaemon(true); indexThread.setName("Compass Indexer"); indexThread.start(); } } public void setBuildIndex(boolean buildIndex) { this.buildIndex = buildIndex; } public void setLazyTime(int lazyTime) { this.lazyTime = lazyTime; } public void setCompassGps(CompassGps compassGps) { this.compassGps = compassGps; }}package cn.changtusoft.s2sh_compass.service.impl;import java.util.ArrayList;import java.util.List;import org.compass.core.Compass;import org.compass.core.CompassHits;import org.compass.core.CompassSession;import org.compass.core.CompassTemplate;import org.compass.core.CompassTransaction;import cn.changtusoft.s2sh_compass.dao.ProductDao;import cn.changtusoft.s2sh_compass.model.Product;import cn.changtusoft.s2sh_compass.service.ProductManager;public class ProductManagerImpl implements ProductManager {private ProductDao productDao;private CompassTemplate compassTemplate;@Overridepublic List searchProducts(String description) {List productList = new ArrayList();Compass compass = compassTemplate.getCompass();CompassSession session = compass.openSession();CompassTransaction tx = null;tx = session.beginTransaction();CompassHits hits = session.queryBuilder().queryString("brand:"+description).toQuery().hits();for (int i = 0; i < hits.length(); i++) {Product p = (Product)hits.data(i);productList.add(p);}tx.commit();return productList;}/* setter */public void setProductDao(ProductDao productDao) {this.productDao = productDao;}public void setCompassTemplate(CompassTemplate compassTemplate) {this.compassTemplate = compassTemplate;}}<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"default-lazy-init="true"><bean id="annotationConfiguration"/><property name="compassSettings"><props><prop key="compass.transaction.factory">org.compass.spring.transaction.SpringSyncTransactionFactory</prop> <prop key="compass.engine.analyzer.MMAnalyzer.CustomAnalyzer">net.paoding.analysis.analyzer.PaodingAnalyzer </prop></props></property><property name="transactionManager" ref="transactionManager" /></bean><bean id="hibernateGpsDevice"ref="sessionFactory" /><property name="mirrorDataChanges"><value>true</value></property></bean><!-- 同步更新索引 --><bean id="compassGps" destroy-method="stop"><property name="compass" ref="compass" /><property name="gpsDevices"><list><beanref="hibernateGpsDevice" /></bean></list></property></bean><bean id="compassTemplate"ref="compass" /></bean><!-- 定时重建索引(利用quartz)或随Spring ApplicationContext启动而重建索引 --><bean id="compassIndexBuilder"ref="compassGps" /><property name="buildIndex" value="true" /><property name="lazyTime" value="10" /></bean> </beans>
