Primefaces FileUpload is not working with PrettyFaces and Spring Boot

问题

I am using Spring Boot 1.5.2.RELEASE with JSF 2.2.14 and Primefaces 6.1 and PrettyFaces 3.4.1.Final.

My pom file is as follows:

the fileupload backing bean is as follows:

package com.myapp.beans;

import java.io.Serializable;

import javax.annotation.PostConstruct;

import org.primefaces.event.FileUploadEvent;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;


@Component("testBean")
@Scope("view")
public class TestBean implements Serializable {

    private static final long serialVersionUID = -3568561158943789169L;

    private static final Logger log = LoggerFactory.getLogger(TestBean.class);

    public void handleFileUpload(FileUploadEvent event) {
        log.info("####### handleFileUpload,file: " + event.getFile().getFileName());
    }   

}

I am running on tomcat 9.0.0.M21 and when choosing the file and clicking upload I get no client side errors and no server side errors and the file is not getting uploaded, although when I turned on primefaces debugging it prints that the file was uploaded:

2017-06-27 07:32:04,926 DEBUG o.p.webapp.filter.FileUploadFilter - Parsing file upload request
2017-06-27 07:32:04,969 DEBUG o.p.webapp.filter.FileUploadFilter - File upload request parsed succesfully, continuing with filter chain with a wrapped multipart request

but the code in the listener in the backing bean was not invoked.

It seems that the issue is because of prettyfaces, when I remove it from the project, the filter works fine.

I also tried the context.xml solution for the prettyfaces issue:

<?xml version="1.0" encoding="UTF-8"?>
<Context allowCasualMultipartParsing="true">
</Context>

and the problem is not solved.

回答1:

i figured it out, there are two solutions:

1- Make the DispatcherType for primefaces upload filter FORWARD ONLY

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

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

2- If you want the primefaces upload filter dispatcher type to be FORWARD and REQUEST you have to explicitly define the pretty faces rewrite filter:

    @Bean
    public FilterRegistrationBean prettyFilter() {
        FilterRegistrationBean prettyFilter = new FilterRegistrationBean(new RewriteFilter());
        return prettyFilter;
    }

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

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

回答2:

I might be late on this one but i know it will save someone some time, i had a similar problem with file upload recently using primefaces6.1 and springboot. My solution was to explicitly set the MultipartConfigElement within the ServletRegistrationBean. The compete working configuration is as follows:

@Configuration
public class JsfConfig extends SpringBootServletInitializer implements ServletContextAware {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        super.onStartup(servletContext);
        servletContext.setInitParameter("primefaces.CLIENT_SIDE_VALIDATION", "true");
        servletContext.setInitParameter("javax.faces.FACELETS_REFRESH_PERIOD", "0");
        servletContext.setInitParameter("javax.faces.PROJECT_STAGE", "Development");
        servletContext.setInitParameter("javax.faces.FACELETS_SKIP_COMMENTS", Boolean.TRUE.toString());
        servletContext.setInitParameter("primefaces.FONT_AWESOME", Boolean.TRUE.toString());
        servletContext.setInitParameter("primefaces.UPLOADER", "commons");
        servletContext.setInitParameter("facelets.DEVELOPMENT", "true");
        servletContext.setInitParameter("primefaces.THEME", "bootstrap");
    }

    @Bean
    public ServletRegistrationBean facesServlet() {
        FacesServlet servlet = new FacesServlet();
        ServletRegistrationBean registration = new ServletRegistrationBean(servlet, "*.xhtml");
        registration.setName("Faces Servlet");
        registration.setLoadOnStartup(1);
        registration.setMultipartConfig(new
                MultipartConfigElement((String) null));
        return registration;
    }

    @Bean
    public ServletListenerRegistrationBean<ConfigureListener> jsfConfigureListener() {
        return new ServletListenerRegistrationBean<ConfigureListener>(new ConfigureListener());
    }

    @Override
    public void setServletContext(ServletContext servletContext) {
        servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
    }

    @Bean
    public FilterRegistrationBean facesUploadFilterRegistration() {
        FilterRegistrationBean registrationBean = new FilterRegistrationBean(new FileUploadFilter(), facesServlet());
        registrationBean.setName("PrimeFaces FileUpload Filter");
        registrationBean.addUrlPatterns("Faces Servlet");
        registrationBean.setDispatcherTypes(DispatcherType.FORWARD, DispatcherType.REQUEST);
        return registrationBean;
    }

    @Bean
    public static CustomScopeConfigurer customScopeConfigurer(){
        CustomScopeConfigurer configurer = new CustomScopeConfigurer();
        Map<String, Object> scopes = new HashMap<String, Object>();
        scopes.put("view", new ViewScope());
        configurer.setScopes(scopes);
        return configurer;
    }
}

I hope that helps.

回答3:

In regardless of Spring Boot, I had this problem before between PrettyFaces and PrimeFaces, it can be solved by configuring the right filters mapping in web.xml as the following:

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

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

<filter>
    <filter-name>Pretty Filter</filter-name>
    <filter-class>com.ocpsoft.pretty.PrettyFilter</filter-class>
</filter>

<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>Faces Servlet</servlet-name>
    <dispatcher>FORWARD</dispatcher>
</filter-mapping>

I'm not sure if this answer would be helpful in your Spring Boot environment, as I don't have a lot of experience in that stack.
