struts2中jsp怎么向action传参？

[fengmi134]

jsp文件，定义了一个keywords
<s:form action="newnew" method="post">
<s:select list="{'原料信息','流程','渣系','热力学','物质','设备'}"
name="keywords"
label="请选择">
</s:select>
<s:submit value="提交"></s:submit>
</s:form>
</body>

action文件接收keywords

public class newnew extends ActionSupport {

private LinkedList list;
private String keywords;

public String getKeywords() {
return keywords;
}

public void setKeywords(String keywords) {
this.keywords = keywords;
}

public LinkedList getList() {
return list;
}

public String execute() {
OntModel text_ontmodel = ModelFactory.createOntologyModel();
OntDocumentManager dm = text_ontmodel.getDocumentManager();
dm.addAltEntry("http://www.owl-ontologies.com/Ontology1303718667.owl#",
"file:" + "new钢铁.owl");
text_ontmodel.read("file:E:/Program Files/Protege_3.4.4/new钢铁.owl");

String prefix = "PREFIX owl: <http://www.w3.org/2002/07/owl#>"
+ "PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>"
+ "PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> "
+ "PREFIX xsd:<http://www.w3.org/2001/XMLSchema#>"
+ "PREFIX eg:<http://www.owl-ontologies.com/Ontology1303718667.owl#>";
String slect = "SELECT ?name ";
String where = "WHERE {" + "?name rdf:type eg:keywords ." + "}";
Query query = QueryFactory.create(prefix + slect + where);
QueryExecution qe = QueryExecutionFactory.create(query, text_ontmodel);
ResultSet results = qe.execSelect();
// 输出结果，这样可以去掉前缀
LinkedList results1 = new LinkedList();
while (results.hasNext()) {

QuerySolution soln = results.nextSolution(); // 查询结果中的每一条（称之为满足条件的一个solution）

String s = soln.get("name").toString();
System.out.print("\t");
StringTokenizer token = new StringTokenizer(s, "#");
token.nextToken();
results1.add(token.nextToken());
qe.close();

}
Iterator it = results1.iterator();
while (it.hasNext()) {
System.out.println(it.next());
}
this.list = results1;
return SUCCESS;
}
在action文件中定义keywords对吗？定义它的get和set？还是别的语句？

没什么问题啊，你想问什么

[fangext520]

jsp --.do/.action------->struts.xml---------携带请求----------->Action类
<--------处理结果返回给xml---

是在后台action中定义keywords并且生成它的get和set方法，
后台取值的时候就能取到keywords
keywords对应前台表单中select的name属性

我贴的这个应该就是action把？这个action能接收到jsp传过来的keywords么？在
String slect = "SELECT ?name ";
String where = "WHERE {" + "?name rdf:type eg:keywords ." + "}";
这一句里面的keywords是传过来的那个值么？
<struts>
<package name="ln" extends="struts-default">
<action name="newnew" class="com.text.newnew">
<result name="success">/index2.jsp</result>

</action>
</package>


这个是结果
<s:iterator value="#request.list">
<s:property />

</s:iterator>
帮忙看下有问题么？运行不出结果。。
