Action方法：

package jp.vacation.holiday.action;

import java.util.ArrayList;

import java.util.List;

import jp.vacation.holiday.form.EasyUIForm;

import net.sf.json.JSONArray;

import net.sf.json.JSONObject;

import org.springframework.context.annotation.Scope;

import org.springframework.stereotype.Controller;

import com.webpump.sdk.struts2.core.AbstractFwAction;

@Controller("EasyUIAction")

@Scope("prototype")

public class EasyUIAction extends AbstractFwAction {

private static final long serialVersionUID = 1L;

private JSONArray jsonArray;

public JSONArray getJsonArray() {

return jsonArray;

}

public void setJsonArray(JSONArray jsonArray) {

this.jsonArray = jsonArray;

}

public String combobox() {

List<JSONObject> jsonList = new ArrayList<JSONObject>();

for (int i = 0; i < 5; i++) {

EasyUIForm easyuiform = new EasyUIForm();

easyuiform.setKey("key" + i);

easyuiform.setValue("value" + i);

JSONObject js = JSONObject.fromObject(easyuiform);

jsonList.add(js);

}

JSONArray jarray = JSONArray.fromObject(jsonList);

this.jsonArray = jarray;

return SUCCESS;

}

form类

package jp.vacation.holiday.form;

public class EasyUIForm {

private String key;

private String value;

public String getKey() {

return key;

}

public void setKey(String key) {

this.key = key;

}

public String getValue() {

return value;

}

public void setValue(String value) {

this.value = value;

}

Struts2 的xml配置

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

"http://struts.apache.org/dtds/struts-2.0.dtd">

<result-types>

<result-type name="json" class="org.apache.struts2.json.JSONResult" />

</result-types>

<param name="root">jsonArray</param>

</result>

</action>

</package>

</struts>

combobox用的是json数组，json数组中放的是json对象
