Primefaces fileUpload가 작동하지 않고 FileUploadFilter가 두 번 호출됩니다.

Spring 3.1.0.RELEASE, JSF 2.x, JPA 2 with Hibernate Provider를 사용하여 웹 애플리케이션을 수행하고 있습니다. 응용 프로그램은 Tomcat 6.35에서 실행됩니다.Primefaces fileUpload가 작동하지 않고 FileUploadFilter가 두 번 호출됩니다.

친숙한 URL 및 스프링 보안 3.1.0.RELEASE를 위해 PrettyFaces 3.3.2를 사용합니다.

Primefaces 3.1을 사용하고 Primefaces의 fileupload 구성 요소를 사용하려고합니다. 슬프게도 작동하지 않습니다.

문제에서

내 콩의 파일은 항상 null 인 것입니다! Tomcat 7에서 시도했지만 아무 것도 바뀌지 않았습니다. Richfaces의 fileUpload 구성 요소를 사용해 보았습니다.하지만 충돌은 피하기 위해 두 개의 구성 요소 라이브러리가 포함되어 있습니다.

Netbeans 7에서 내 응용 프로그램을 디버깅하고 FileUploadFilter :: doFilter에 중단 점을 삽입했습니다. doFilter가 두 번 호출된다는 것을 알았습니다. MultipartRequest가 처음 만들어지면 양식 입력을 파싱하고 파일을 감지합니다. 하지만 두 번째로 요청이 소비 된 것으로 보이며 MultipartRequest에 아무 것도 채워지지 않습니다. Primefaces FileUploadRenderer는 두 번째 MultipartRequest를 사용하므로 해당 파일에 파일이 없습니다.

FileUploadFilter가 두 번 호출되는 것이 정상입니까? fileUpload 구성 요소는 어떻게 작동합니까?

솔루션은

난 단지 web.xml 파일을 변경 prettyfaces 필터에 ASYNC을 추가하고 파일 업로드 필터의 모든 디스패처를 제거했다. 당신

나는 당신이 당신의 PrettyFaces 필터 매핑에 ASYNC 디스패처를 추가 할 필요가 믿는 :

<!-- Pretty faces --> 
<filter> 
    <filter-name>Pretty Filter</filter-name> 
    <filter-class>com.ocpsoft.pretty.PrettyFilter</filter-class> 
</filter> 
<filter-mapping> 
    <filter-name>Pretty Filter</filter-name> 
    <url-pattern>/*</url-pattern> 
    <dispatcher>FORWARD</dispatcher> 
    <dispatcher>REQUEST</dispatcher> 
    <dispatcher>ERROR</dispatcher> 
    <dispatcher>ASYNC</dispatcher> 
</filter-mapping>

PrimeFaces은 내가 잘못 아니에요 경우 구성 요소가 ASYNC 업로드를 사용하여 업로드 할 수 있습니다.

안녕하세요! PrickFaces FileUpload Filter에서 모든 Dispatcher를 제거하고 제거하는 것처럼 PrettyFilter에 ASYNC를 추가했습니다. 감사합니다! –

Primefaces fileUpload가 작동하지 않고 FileUploadFilter가 두 번 호출됩니다.
