The file in the Spring file does not work.

Question

I am running a JSF project that runs it using Spring Boot and uses the entire Spring environment. Configuration: Mojarra 2.2.8 + Primefaces 5.1 + Spring Download 1.1.9. What my POM.xml file looks like:

<?xml version="1.0" encoding="UTF-8"?>

</project>

As stated above, I am setting up a project to run on Tomcat 7.0.57 (compatible with Servlet 3.0). All JSF functions work correctly, but the problem is that I can’t get the work with the Primefaces components p:fileUpload, neither the basic nor the advanced versions. The file download listener does not start and no errors occur.

What is my bean code:

@ManagedBean
@javax.faces.bean.ViewScoped
public class Bean {

    public void handleFileUpload(FileUploadEvent event) {
        FacesMessage message = new FacesMessage("Succesful", event.getFile()
                .getFileName() + " is uploaded.");
        FacesContext.getCurrentInstance().addMessage(null, message);
        System.out.println("Uploaded!");
    }

}

And here is what my xhtml file looks like under the template:

<ui:composition template="/WEB-INF/template.xhtml"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.org/ui">

    <ui:define name="content">
        <h:form>
            <p:fileUpload fileUploadListener="#{bean.handleFileUpload}" />
        </h:form>
    </ui:define>
</ui:composition>

, , Apache Commons. , web.xml, :

@Bean
public ServletContextInitializer initializer() {
    return new ServletContextInitializer() {
        @Override
        public void onStartup(ServletContext servletContext)
                throws ServletException {
            servletContext.setInitParameter("primefaces.THEME", "bluesky");
            servletContext.setInitParameter(
                    "javax.faces.FACELETS_SKIP_COMMENTS", "true");
            servletContext.setInitParameter(
                    "com.sun.faces.expressionFactory",
                    "com.sun.el.ExpressionFactoryImpl");
            servletContext.setInitParameter("primefaces.UPLOADER",
                    "commons");
        }
    };
}

Answer 2

xml Java:

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

@Configuration

@Bean
public FilterRegistrationBean FileUploadFilter() {
    FilterRegistrationBean registration = new FilterRegistrationBean();
    registration.setFilter(new org.primefaces.webapp.filter.FileUploadFilter());
    registration.setName("PrimeFaces FileUpload Filter");
    return registration;
}

Answer 3

, Spring boot 1.4.2.RELEASE, Primefaces 6.0, OCP Soft rewrite 2.0.12.Final, JSF 2.1.29-08 , Tomcat 8, Spring hiddenHttpMethodFilter.

@Bean
public FilterRegistrationBean hiddenHttpMethodFilterDisabled(
        @Qualifier("hiddenHttpMethodFilter") HiddenHttpMethodFilter filter) { 
    FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(filter);
    filterRegistrationBean.setEnabled(false);
    return filterRegistrationBean;
}
