I tried maven clean and maven install for update dependeces.
I changed web.xml many times. I belive the problem is relationship with my anotation, i m using #Autowired (Spring) but i change it an donsen't work.
How i resolve this problem?
I m using:
Primefaces 6.0,
Java 8,
Spring Data,
Spring MVC
my web xml:
<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>
<url-pattern>*.jsf</url-pattern>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
<dispatcher>ASYNC</dispatcher>
</filter-mapping>
JSF:
<p:fileUpload id="fileDescAto" auto="true" multiple="false"
invalidFileMessage="Tipo de Arquivo Inválido:"
disabled="#{not empty searchDocumentoBean.descAtoArquivoFileName}"
update="messagesDialog #this panelGroupFileDescription"
allowTypes="/(\.|\/)(pdf)$/" sizeLimit="10485760"
invalidSizeMessage="Tamanho de arquivo excedido (10MB):"
fileUploadListener="#{searchDocumentoBean.adicionaArquivoUpload}"
label="Escolher Arquivo..." mode="advanced" />
Bean:
public void adicionaArquivoUpload(FileUploadEvent ev) {
String[] name = ev.getFile().getFileName().split("\\\\");
descAtoArquivo = ev.getFile().getContents();
descAtoArquivoFileName = name[name.length-1];
}
public void removeArquivoUpload() {
descAtoArquivo = null;
descAtoArquivoFileName = null;
}// GET AND SET OMITED
Head annotation My bean:
#Component
#Scope("view")
#ManagedBean(name = "searchDocumentoBean")
#URLMappings(mappings = {
#URLMapping(id ="searchDocumento", pattern = "/searchDocumento", viewId = "/resources/pages/documento/searchDocumento.jsf")
})

Answer 1

This solve my problem:
Listener method in p:fileUpload is never invoked in primefaces
Besides That.
i need especify location the Faces Servlet:
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
javax.faces.webapp.FacesServlet
I needed especify resource primefaces depends for fileupload works fine>
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>commons</param-value>
</context-param>
In some versions of primefaces it is not necessary to specify this configuration. I am currently using version 6.0, which believed that this specification was not necessary in web.xml because it is a newer version, but it was necessary.
