struts2+hibernate+spring+compass进行全文搜索

今天完成了一个搜索功能,把compass整合到项目当中,做一下笔记,希望对大家有用。
1.搜索文本框

<s:form action="search.action" method="post">
<input class=lst type=text name=queryString maxlength=2048 value="<s:property value='queryString'/>" title="搜索">
<input type=submit name="btnG" class=lsb value="搜索图书">
</s:form>

2.struts.xml配置
<action name="search" class="com.book.action.ProductAction" method="search">
<result name="search">searchResults.jsp</result>
</action>
3.Action层
public String search(){
	List results=productService.searchProducts(productVo.getQueryString());
	ServletActionContext.getRequest().setAttribute("searchresults", results);
	ServletActionContext.getRequest().setAttribute("queryString", productVo.getQueryString());
	return "search";
	}


4.service层
public List searchProducts(String queryString) {
	Compass compass = compassTemplate.getCompass();
	CompassSession session=compass.openSession();
	session.beginLocalTransaction();
	List list = new ArrayList();
		
	CompassHits hits= session.queryBuilder().queryString("name:"+queryString).toQuery().hits();
		
	for(int i=0;i<hits.length();i++){
	ProductInfo hit=(ProductInfo)hits.data(i);
	ProductInfo productInfo = this.find(hit.getId());
	String name_highlighter = hits.highlighter(i).fragment("name");   
	productInfo.setName(name_highlighter); 
	list.add(productInfo);
	}
	session.close();
	return list;
	}


记得注入compassTemplate

6.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.

*/

    private boolean buildIndex = false;

                System.out.println("begin compass index...");
                long beginTime = System.currentTimeMillis();
                // 重建索引.
