[SPRING] Fileupload가 Primefaces에서 작동하지 않습니다.
SPRINGFileupload가 Primefaces에서 작동하지 않습니다.
Primefaces의
에 몇 가지 문제가 있습니다. 처음에는 2018 페이지의 Fileupload 문서에서 스 니펫을 시도했습니다. 첫 번째 문제는 스 니펫을 사용하면 업로드 기능이 호출되지 않는다는 것입니다.
public void upload() {
System.out.println("This is never shown");
if(file != null) {
System.out.println("This is never shown");
}
}
html :
<h:form enctype="multipart/form-data">
<p:fileUpload value="#{fileUploadView.file}" mode="simple" />
<p:commandButton value="Submit" action="#{fileUploadView.upload}" ajax="false"/>
</h:form>
나는 많은 다른 스 니펫과 솔루션을 시도했다. 고급 모드에서 fileUploadListener를 사용하여 h : form, ...에 enctype을 삭제했습니다.
mode = "simple"을 선택하고 ajax = "true"와 결합하면 FileUploadView.upload () 함수가 호출되지만 파일은 항상 NULL입니다.
이 포럼에서 가능한 모든 솔루션을 읽었 기 때문에 위의 문제를 언급 할 수 있습니다. 또한 모든 제안 된 종속성 및 컨텍스트 매개 변수와 필터를 추가했지만 작동하지 않습니다.
여기에 내 pom.xml, web.xml 및 전체 .java 코드를 게시합니다. pom.xml

[편집] 깨끗한 Spring 프로젝트를 만들려고 노력했으며
를 만들 수있는 모든 가능성을 시도했지만 그 중 아무 것도 작동하지 않았습니다. 그러나 나는 브라우저의 트래픽을 살펴 보았고 흥미로운 것을 발견했습니다. . 업로드 버튼을 누르면 POST 문이 즉시 나타나고 다른 GET은 1-2 초 후에 나타납니다.
해결법
-
==============================
1.설명서에 나온다.
설명서에 나온다.
FileUploadEvent 매개 변수와 함께 fileUploadListener를 추가하십시오. AJAXical 버튼을 만듭니다. enctype을 잃어 버리십시오. fileUpload의 값으로 귀찮게하지 마십시오.
