[搜索] Compass整合Spring Hibernate配置

首先：Compass已死，已经为ElasticSearch取代，你可以把ES看作是Compass 3

Compass整合Spring Hibernate最好通过注解方式，这样就可以省略*.cmd.xml与*.cpm.xml

applicationContext.xml:

随Spring ApplicationContext启动创建索引类

/** * implements InitializingBean 随着spring 的初始化而启动 * 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{private CompassGps compassGps;private long delay = 1000; // spring启动后 延迟1s 运行程序，进行索引重建// 是否定时构建索引，默认为定时构建 ，如果置为false 而此程序只在spring初始化时创建索引boolean buildIndex = false;private long period = 1000 * 60;// 每隔1min进行一次索引重建,监视数据库中数据的变化public void afterPropertiesSet() throws Exception {if (buildIndex) {buildIndex();}}public void buildIndex() {Timer timer = new Timer("CompassIndexBuilder", true);timer.schedule(new TimerTask() {@Overridepublic void run() {System.out.println("CompassIndexBuilder开始重建索引 --> Build Compass index at : "+new Date());long beginTime = System.currentTimeMillis();// 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("CompassIndexBuilder完成重建索引-->用时" + costTime + " milliseconds");}}, delay, period);}//------------------------------------------------------------------public void setCompassGps(CompassGps compassGps) {this.compassGps = compassGps;}public void setDelay(long delay) {this.delay = delay;}public void setPeriod(long period) {this.period = period;}public void setBuildIndex(boolean buildIndex) {this.buildIndex = buildIndex;}}
