 [Java Open Source]基于JAVA 5.0特性的compass应用
软件技术
lhwork 发表于 2006/7/31 11:44:48 |
| JAVA 5.0里面有个很鲜明的就是annotation 在这里我也就是用他来配置实体类，而不用写xml .其他的配置就差不多一样了//声明此类的别名为article，在COMPASS里面可以直接用article来访问@Searchable(alias = "article")public class Article extends BaseEntity {
..............//这个是必须的，我也没仔细看为什么 public Article() {
}
public List<Special> getSpecialList() { return specialList; }
/** * @return Returns the author. *///设置搜索的别名为author，在查询的时候可以用author=？来检索 @SearchableProperty(name = "author") public String getAuthor() { return author; }
/** * @param author * The author to set. */ public void setAuthor(String author) { this.author = author; }
/** * @return Returns the brief. */ public String getBrief() { return brief; }
/** * @param brief * The brief to set. */ public void setBrief(String brief) { this.brief = brief; }
/** * @return Returns the category. */ @SearchableComponent public Category getCategory() { return category; }
/** * @param category * The category to set. */ public void setCategory(Category category) { this.category = category; }
/** * @return Returns the content. */ public String getContent() { return content; }
下一步就配置SPING了//一定要声明的 要不上面的类里面的设置就没法工作<bean id="annotationConfiguration" class="org.compass.annotations.config.CompassAnnotationsConfiguration"></bean>//LocalCompassBean是compass的一个实现类，用他来创建索引<bean id="compass" class="org.compass.spring.LocalCompassBean"> <property name="classMappings"> <list>//这里直接写他的类就可以了 以前是写的XML <value>com.aurora.netschool.entity.Article</value> <value>。。。。</value> </list> </property> <property name="compassConfiguration" ref="annotationConfiguration" /> <property name="compassSettings"> <props> <prop key="compass.engine.connection">file://${pathIndex}</prop> <prop key="compass.transaction.factory">org.compass.spring.transaction.SpringSyncTransactionFactory</prop> </props> </property> <property name="transactionManager" ref="transactionManager" /> </bean>//如果你配置了 HIBERNATE等 在这里你要加上autowire="no" 要不你肯定在启动的时候就出错<bean
id="compassGps" class="org.compass.gps.impl.SingleCompassGps"
init-method="start" destroy-method="stop" autowire="no"> <property name="compass" ref="compass" /> <property name="gpsDevices"> <list> <bean class="org.compass.spring.device.hibernate.SpringHibernate3GpsDevice" autowire="no"> <property name="name"> <value>hibernateDevice</value> </property> <property name="sessionFactory" ref="sessionFactory" /> <property name="mirrorDataChanges"> <value>false</value> </property> </bean> </list> </property> </bean>下面就是写方法类了public class SearchEngineServiceImpl { ArticleDao articleDao;//这里的变量名要和SPRING里面的一样的 这里可以用GET SET得到SPRING里面的BEAN CompassGps compassGps;
compasscompass;
/** * @return Returns the compass. */ public compass getCompass() { return compass; }
/** * @param compass * The compass to set. */ public void setCompass(Compass compass) { this.compass = compass; }
/** * @return Returns the compassGps. */ public CompassGps getCompassGps() { return compassGps; }
/** * @param compassGps * The compassGps to set. */ public void setCompassGps(CompassGps compassGps) { this.compassGps = compassGps; }
/** * @return Returns the articleDao. */ public ArticleDao getArticleDao() { return articleDao; }
/** * @param articleDao * The articleDao to set. */ public void setArticleDao(ArticleDao articleDao) { this.articleDao = articleDao; }
public String getPathIndex() { return com.aurora.Configuration.getInstance().getConfig("pathIndex") + "/"; }
/* * 创建检索文件 * * @see com.aurora.netschool.service.SearchEngineService#creatIndexByCompass() * compass创建索引 */ public void creatIndexByCompass() throws IOException { compassGps.index(); }
public List<Article> searchByCompass(String queryString, String type, String categoryName) { List<Article> articleList = new ArrayList<Article>(); CompassSession session=compass.openSession();。。。。。。。 CompassHits hits=query.hits(); for (int i = 0; i < hits.getLength(); i++) { Article article = (Article) hits.data(i); //hits.hit(i).getData(). if ("title".equals(type)) { article.setTitle(hits.highlighter(i).fragment(type)); } else if ("author".equals(type)) { article.setAuthor(hits.highlighter(i).fragment(type)); } else if ("content".equals(type)) { article.setHtmlContent(hits.highlighter(i).fragment(type)); } articleList.add(article); } compassTran.commit(); session.close(); return articleList; }}好了 自己配置用一下吧 |

| SpringHibernate3GpsDevice
mirrorDataChanges属性如果设置为false.索引将不会自动被同步 |
