JSF jsp页面和后台bean传值问题

:jsf中后台bean给jsp传值很常见也很容易

例

SearchBean 中

public class SearchBean {

private String media_name=;

public String getMedia_name() {

return media_name;

}

public void setMedia_name(String media_name) {

dia_name = media_name;

}

}

facesconfigxml文件中配置bean

<managedbean>

<managedbeanname>serach</managedbeanname>

<managedbeanclass>adminSearchBean</managedbeanclass>

<managedbeanscope>request</managedbeanscope>

</managedbean>

JSP页面中使用

<h:outputText value=文件名称(必填) />

<h:inputText value=#{dia_name} ></h:inputText>

:jsp向后台bean传值

例

JSP页面中

<h:commandButton value=上传 actionListener=#{searchuploadFile} styleClass=button>

<f:attribute name=attrname value=#{visitoruserId} />

</h:commandButton>

在bean中

public void uploadFile(ActionEvent ae) throws Exception{

user_name = (String) aegetComponent()getAttributes()get(attrname);

}
