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">
<struts>
    <package name="vacation" extends="vacation_common">
        <result-types>
            <result-type name="json" class="org.apache.struts2.json.JSONResult" />
        </result-types>
        <action name="SRCEasyUI_combobox" method="combobox" class="EasyUIAction">
            <result type="json">
        <!--jsonArray必须在Action中定义，必须写它的get，set方法 -->
                <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
