Primefaces <P：文件上传不调用Bean方法

Question

我试图实现primefaces文件上传，但没有调用bean方法，顺便说一下我使用Spring框架和prettyfaces：

faces-config.xml中：

<?xml version="1.0" encoding="UTF-8"?> 
<faces-config version="2.2" xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
    http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"> 
    <application> 
     <resource-bundle> 
      <base-name>label</base-name> 
      <var>msg</var> 
     </resource-bundle> 
     <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver> 
    </application> 
</faces-config> 

web.xml文件：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 
    version="3.0">

     </init-param> 
    </filter> 

    <filter-mapping>

    </servlet> 

    <servlet-mapping> 
     <servlet-name>Faces Servlet</servlet-name> 
     <url-pattern>*.xhtml</url-pattern> 
    </servlet-mapping> 
</web-app> 

.xhtml代码：

<h:form enctype="multipart/form-data" prependId="false"> 
          <p:fileUpload mode="simple" value="#{templateController.file}" /> 
          <p:commandButton value="Upload" actionListener="#{templateController.upload}" ajax="false" /> 
         </h:form> 

豆方法：

public void upload() { 
    FacesMessage msg = new FacesMessage("Success! is uploaded."); 
    FacesContext.getCurrentInstance().addMessage(null, msg); 
} 

我尝试添加转发给过滤器，因为我还使用漂亮的面孔，但仍然没有工作，谢谢。

好我解决了很多问题，我的解决方案是在web.xml文件中添加一个context-param（primefaces.UPLOADER）（检查this答案请），这个文件看起来是这样的，也可能是有帮助的设置项目阶段发展（在此文件中注释），这可以给你相关的调试过程中的一些附加信息：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 
    version="3.0"> 

    <listener> 
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 

    <!-- context-param>

      <param-value>Development</param-value> 
    </context-param--> 

    <context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/application-context.xml</param-value> 
    </context-param> 

    <context-param> 
     <param-name>javax.faces.DEFAULT_SUFFIX</param-name>

    </context-param> 

    <context-param> 
     <param-name>log4j-config-location</param-name>

    </context-param> 
    <listener> 
     <listener-class>co.com.core.commons.LogContextListener</listener-class> 
    </listener> 
    <!-- ############################################# --> 
    <!-- # File upload          # --> 
    <!-- ############################################# -->

      <param-name>thresholdSize</param-name>

尝试执行以下，

此方法添加到你的bean，

public void handleProfileFileUpload(FileUploadEvent event) { 
    if (event != null) { 


     try { 
      InputStream inputStream = event.getFile().getInputstream(); 
      // Set inputstream to your object 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
} 

删除命令按钮并修改类似于这样的FileUpload配置，fileUploadListener最后经过处理上传

<p:fileUpload fileUploadListener="#{<your bean>.handleProfileFileUpload}" 
          mode="advanced" sizeLimit="2097152" 
          allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />

如果你正在使用Spring MVC，你的过滤器映射应该指向Spring DispatcherServlet而不是Faces Servet。

<filter> 
    <filter-name>PrimeFaces FileUpload Filter</filter-name> 
    <filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class> 
</filter> 

<filter-mapping> 
    <filter-name>PrimeFaces FileUpload Filter</filter-name> 
    <servlet-name>Spring MVC Servlet</servlet-name> 
</filter-mapping>
