Servlet调用在jsf页面中不起作用
Servlet调用在jsf页面中不起作用
提问于 2018-05-29 08:05:52
在一个jsf页面中，我调用了一个使用when服务的servlet，当我单击send时，没有任何操作，它不会调用servelt。
这是Servlet Parqueo
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();
Map<String,String> requestParams = ec.getRequestParameterMap();
String Nombre = requestParams.get("nombre");
String Tipo = requestParams.get("tipo");
String Placa = requestParams.get("tipo");
String Fecha= requestParams.get("fecha");
String Hora_in = requestParams.get("horain");
String Hora_out= requestParams.get("horaout");
if(Hora_in !=null && !Hora_in.isEmpty() && Hora_out !=null && !Hora_out.isEmpty()){
jaxws.Parking_Service service;
jaxws.Parking port;
try{
service= new jaxws.Parking_Service();
port=service.getParkingPort();
String parqueo = port.reserva(Hora_in, Hora_out);
request.setAttribute("result",parqueo);
response.getWriter().print( Nombre + "</p>");
response.getWriter().print( Tipo + "</p>");
response.getWriter().print( Placa + "</p>");
response.getWriter().print( Fecha + "</p>");
request.getRequestDispatcher("reserva.xhtml").forward(request, response);
}我接收索引的数据，保存它们并使用then服务，然后将数据和结果发送到页面resultado.xhtml
这是来自这个页面的index.xhtml，我称之为serlvet
<h:body>
<f:view>
<h:form>
<h:outputText value="Reserva de Parqueadero " />
<br/>
<h:panelGrid columns="2">
<p:outputLabel value="Nombre:" for="nombre" />
<p:inputText id="nombre" title="Nombre" required="true" requiredMessage="The Id field is required."/>
<p:outputLabel value="Tipo:" for="tipo" />
<p:inputText id="tipo" title="Tipo" required="true" requiredMessage="The Id field is required."/>
<p:outputLabel value="Placa:" for="placa" />
<p:inputText id="placa" title="Placa" required="true" requiredMessage="The Id field is required."/>
<p:outputLabel value="Hora Ingreso:" for="horain" />
<p:inputText id="horain" title="Hora Ingreso" required="true" requiredMessage="The Id field is required."/>
<p:outputLabel value="Hora Salida:" for="horaout" />
<p:inputText id="horaout" title="Hora Salida" required="true" requiredMessage="The Id field is required."/>
<p:outputLabel value="Fecha:" for="fecha" />
<p:calendar id="fecha" value="#{calendar.date1}" showOn="button" navigator="true"></p:calendar>
</h:panelGrid>
<br/>
<h:commandButton value="Enviar" action="/parqueo.do"/>
</h:form>
</f:view>
</h:body>这是result.xhtml
<h:body>
<f:view>
<h:outputText value="Nombre" />
<h:outputText value="#{session.getAttribute(name)}"/>
<h:outputText value="Tipo" />
<h:outputText value="#{session.getAttribute(tipo)}"/>
<h:outputText value="Placa" />
<h:outputText value="#{session.getAttribute(placa)}"/>
<h:outputText value="Fecha" />
<h:outputText value="#{session.getAttribute(fecha)}"/>
<f:convertDateTime pattern="MM/dd/yyyy" />
<h:outputText value="Resultado" />
<h:outputText value="${result}"/>
</f:view>
</h:body>在此页面上，它应该显示输入的数据和由parqueo的the服务返回的值
这是web.xml
<servlet>
<servlet-name>Parqueo</servlet-name>
<servlet-class>controlador.Parqueo</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Parqueo</servlet-name>
<url-pattern>/parqueo.do</url-pattern>
</servlet-mapping>回答 1

为什么要使用servlet？如果您正在使用JSF，那么使用ManagedBean将其与一些UI组件链接起来( Faces Servlet将为您映射请求/post)。
