我正在 Eclipse IDE 中使用 mvc 开发一个自定义 portlet。

以下是我的场景：

我有一个表名restaurant，从addrestaurant.jsp页面开始，我在餐厅表中添加数据。

在我的addrestaurant.jsp页面中，我有以下选择控件代码，它需要选择多个值：

<label>Select Ad Type<span class="f_req">*</span></label>                                                
<select data-placeholder="- Select Ad Type -" class="chzn-select" multiple name="ad_type" value="<%=restaurantOBJ.getAdtypeId()%>">
    <option value="1">Standby Ad</option>
    <option value="2">Homepage Ad</option>
    <option value="3">Slider Ad</option>
    <option value="4">Event Based Ad</option>
</select>

现在这个adtype选择的addrestaurant.jsp将被插入到一个rest_map_adtype表中，我想将这些选择的值与最后创建的餐厅主键的引用一起添加。

那么我怎样才能得到restaurant最后编辑的主键

更多解释让我给出一些代码片段：

public void addRestaurant(ActionRequest request, ActionResponse response) {

    log.info("Inside addRegistration");
    List<String> errors = new ArrayList<String>();

    restaurant rest = RestaurantActionUtil
            .getRestaurantFromRequest(request);     

    boolean restValid = RestaurantValidator
            .validateRestaurant(rest, errors);

    if (restValid) {
        try {
            log.info(rest);

            restaurant test = restaurantLocalServiceUtil
                    .addrestaurant(rest);

        //Above Code will add the all data which is in my addrestaurant.jsp accept just selected control values

            String[] adtype_ID=request.getParameterValues("ad_Type");

            //here am taking the select tag's multiple value in one string array

因此，在这一行之后，我需要将rest_map_Adtype表中的所有值添加到餐厅主键的引用中，该主键是使用addrestaurant(rest)上面一行的方法创建的。

我怎样才能使它成为可能？

或者在表中插入行后如何获得主键？

我的 ActionUtil.class 如下

public restaurant addRestaurant(restaurant restParam) {
        restaurant restVar;

        try {



            restVar = restaurantPersistence.create(counterLocalService
                    .increment(restaurant.class.toString()));
        } catch (SystemException e) {
            e.printStackTrace();
            return restVar = null;
        }

        try {



            resourceLocalService.addResources(restParam.getGroupId(),restParam.getGroupId(), restParam.getUserId(),
                    restaurant.class.getName(),restParam.getPrimaryKey(), false,true,true);
        } catch (PortalException e) {
            e.printStackTrace();
            return restVar = null;
        } catch (SystemException e) {
            e.printStackTrace();
            return restVar = null;
        }

        restVar.setName(restParam.getName());
        restVar.setAdress(restParam.getAdress());
        restVar.setCity(restParam.getCity());
        restVar.setPin(restParam.getPin());
        restVar.setState(restParam.getState());
        restVar.setCountry(restParam.getCountry());
        restVar.setContactno(restParam.getContactno());
        restVar.setEmail(restParam.getEmail());
        restVar.setWebsite(restParam.getWebsite());
        restVar.setCuisinetype(restParam.getCuisinetype());
        restVar.setPersonalmail(restParam.getPersonalmail());
        restVar.setPersonalname(restParam.getPersonalname());
        restVar.setPersonalPhone(restParam.getPersonalPhone());
        restVar.setNoofemenuagent(restParam.getNoofemenuagent());
        restVar.setLicensekey(restParam.getLicensekey());
        restVar.setRestregId(restParam.getRestregId());
        restVar.setNoofdiningtable(restParam.getNoofdiningtable());
        restVar.setAvgnoofcustomermonthly(restParam.getAvgnoofcustomermonthly());
        restVar.setAveragroupagevisit(restParam.getAveragroupagevisit());
        restVar.setImpoflocation(restParam.getImpoflocation());
        restVar.setAvgmonthlycheckamount(restParam.getAvgmonthlycheckamount());
        restVar.setCostperthousandimpression(restParam.getCostperthousandimpression());
        restVar.setAdtypeId(restParam.getAdtypeId());
        //restVar.setNoofdiningtable(restParam.getNoofdiningtable());
        //restVar.setAvgnoofcustomermonthly(restParam.getAvgnoofcustomermonthly());


        restVar.setIsactive(restParam.getIsactive());
        restVar.setCreateddate(restParam.getCreateddate());
        restVar.setLastmodifiedby(restParam.getLastmodifiedby());
        restVar.setModifieddate(restParam.getModifieddate());
        restVar.setGroupId(restParam.getGroupId());
        restVar.setUserId(restParam.getUserId());
        restVar.setIsdeleted(restParam.getIsdeleted());
        restVar.setRestregId(restParam.getRestregId());

        //restVar.setOrganizationId(restParam.getOrganizationId());

        try {
            return restaurantPersistence.update(restVar, false);
        } catch (SystemException e) {
            e.printStackTrace();
            return restVar = null;
        }
    }

以下是我的对象餐厅，添加餐厅后返回以下值 {restId=0, name=aaaa, isactive=false, userId=10158, groupId=10180, createddate=Fri Oct 26 12:40:53 GMT 2012, lastmodifiedby=10158, modifieddate=Fri Oct 26 12:40:53 GMT 2012, restregId=12333, adress=, city=AHMEDABAD, pin=, state=, country=, contactno=, email=, website=, cuisinetype=, noofemenuagent=0, personalname=, personalPhone=, personalmail=, adtypeId=0, isdeleted=false, licensekey=12333, noofdiningtable=0, averagroupagevisit=0, impoflocation=, avgnoofcustomermonthly=0, avgmonthlycheckamount=0, costperthousandimpression=0.0}

restaurantLocalServiceUtil 类

public static emenu.advertise.database.model.restaurant addrestaurant(
        emenu.advertise.database.model.restaurant restaurant)
        throws com.liferay.portal.kernel.exception.SystemException {
        return getService().addrestaurant(restaurant);
    }

    /**

    *

    public static emenu.advertise.database.model.restaurant createrestaurant(
        long restId) {
        return getService().createrestaurant(restId);
    }

restVar此语句在您的ierestaurant对象中设置主键：

restVar = restaurantPersistence.create(counterLocalService
                .increment(restaurant.class.toString()));

当你这样做时：

return restaurantPersistence.update(restVar, false);

它实际上返回restaurant应该包含生成的主键的对象。

所以在下面的电话之后：

restaurant test = restaurantLocalServiceUtil.addrestaurant(rest);

你可以简单地做：

long restId = test.getPrimaryKey(); // this would return the primary-key

希望这可以帮助。
