Java 以Struts 1表单显示列表

Java 以Struts 1表单显示列表,java,struts,taglib,struts-1,Java,Struts,Taglib,Struts 1,我必须编写一个backoffice页面,以确定在Struts 1应用程序中,哪些商店必须显示在frontoffice页面上。因此,我有一个包含在表单中的商店(代码中为精品店)列表 表格: public class ListeBoutiquesForm extends ActionForm { private List<Boutique> boutiques = new ArrayList<Boutique>(); public List<Bout

我必须编写一个backoffice页面,以确定在Struts 1应用程序中,哪些商店必须显示在frontoffice页面上。因此,我有一个包含在表单中的商店(代码中为精品店)列表

表格:

public class ListeBoutiquesForm extends ActionForm {

    private List<Boutique> boutiques = new ArrayList<Boutique>();

    public List<Boutique> getBoutiques() {
        return boutiques;
    }

    public void setBoutiques(List<Boutique> boutiques) {
        this.boutiques = boutiques;
    }

}
精品类包含一个id、一个名称和一个名为“selected”的布尔值。我想为精品店列表中的每个元素显示一个复选框,并显示一个调用save操作的submit按钮,但是我缺乏编写JSP的Struts taglib知识。你能帮忙吗?我知道它应该包含一个
逻辑:迭代
,一个
html:checkbox
,可能还有一个
html:hidden
来存储id,但我感觉有些东西缺失了,有些东西我不明白。可以这么说,它们是如何联系在一起的?如何在保存操作中获取具有更新值的ListFinanesForm

编辑:

根据Susie的建议,我提出了以下JSP:

<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-nested.tld" prefix="nested" %> 

<html:errors/>
<html:form action="/admin/boutiqueviparis">
    <input type="hidden" name="reqCode" value="sauverBoutiques" />

    <table class="tableStatic noHead">
        <logic:notEmpty name ="viparisListeBoutiquesForm" property="boutiques">
            <logic:iterate id="boutique" name ="viparisListeBoutiquesForm" property="boutiques">
                <tr>
                    <td>
                        <html:hidden name ="boutique" property="id" />
                        <bean:write name="boutique" property="nom" />
                    </td>
                    <td>
                        <html:checkbox name="boutique" property="selected" value="true" />
                    </td>
                </tr>
            </logic:iterate>
            <html:submit styleClass="boutonrouge" value="Valider" onclick="this.form.reqCode.value='sauverBoutiques';return window.confirm('Modification validée');"/>
        </logic:notEmpty>
    </table>
</html:form>
我可以在Hibernate日志中看到update语句,但实际上没有保存任何内容。我记录了我的
选择的
字段的值,实际上,它是初始值,然后在显示的表单中更改它。有点令人费解

编辑:


实际上,
在最终的HTML中显示为
,用“id”代替id值。但是我不知道如何解决这个问题…

下面是你应该做的事情。struts-config.xml文件将所有内容粘合在一起的配置文件

parameter ---> which method to call
name---> name of the action form
path---> URL
type---> action class that is invoked by the above url. 
forward---->where to forward once it's done.
如您所见,我在myMethod()中设置了列表,并在下面的jsp中设置了访问权限
