PhotoCam primefaces

waguener · Dezembro 10, 2018, 5:48pm

Olá Devs estou temdo alguns problemas para implementar este componente no meu projeto, isto foi oque fiz até o momento:
Esta é a tela -
<p:dialog widgetVar=“dialogCamera” resizable="false"
position=“center” showHeader=“false”>

				<p:panelGrid columns="3" layout="grid" id="croped"
					columnClasses="ui-grid-col-4,ui-grid-col-4,ui-grid-col-4"
					styleClass="panelgrid-noborder">

					<p:panel id="camera" header="Web Cam">
						<div style="height: 240px;">
							<p:photoCam widgetVar="photoCam"
								listener="#{funcionarioController.capturar}" />
						</div>
						<p:spacer height="10" />
						<center>
							<p:commandButton value="Capturar" process="camera"
								update="croped" onclick="PF('photoCam').capture();" />
						</center>

					</p:panel>

					<p:panel id="cropped_com_foto" header="Foto Capturada"
						style="width: 360px; height: 350px;">
						<div style="height: 240px;">
							<p:imageCropper value="#{funcionarioController.imagemCortada}"
								initialCoords="225,75,300,125" aspectRatio="0.8"
								id="imageCropperFotoId"
								image="#{pageContext.servletContext.contextPath}/resources/upload/#{funcionarioController.fotoCapturada}" />
						</div>
						<p:spacer height="10" />
						<center>
							<p:commandButton id="cortar_foto" value="Cortar"
								action="#{funcionarioController.cortar}" />
						</center>
					</p:panel>

					<p:panel id="panelFotoRecortadaId" header="Foto Recortada"
						style="width: 360px; height: 350px;">
						<div style="height: 240px;">
							<p:graphicImage
								value="/resources/upload/#{funcionarioBean.fotoCortada}" />
						</div>
						<p:spacer height="10" />
						<center>
							<p:commandButton id="salvar_foto" icon="accept-16x16"
								value="Salvar" />
						</center>
					</p:panel>
				</p:panelGrid>
				<p:commandButton value="Fechar" type="button"
					onclick="PF('dialogCamera').hide()" />
			</p:dialog>

E este é o controller -
// Tirar foto com webcam

public void capturar(CaptureEvent captureEvent) {
	System.out.println("Comecar a capturar");
	byte[] data = captureEvent.getData();
    this.fotoCapturada = "capturada" + getNumeroRandomico() + ".jpg";
    
    String newFoto = servletContext.getRealPath("") + "resources" + File.separator + "upload" + File.separator + this.fotoCapturada;
    criaArquivo(newFoto, data);
    System.out.println("Caminho da foto"+data);
}

private void criaArquivo(String arquivo, byte[] dados) {
	FileImageOutputStream imageOutput;
	try {
		imageOutput = new FileImageOutputStream(new File(arquivo));
		imageOutput.write(dados, 0, dados.length);
		imageOutput.close();
		
	} catch (FileNotFoundException ex) {
		Logger.getLogger(FuncionarioController.class.getName()).log(Level.SEVERE, null, ex);
		FacesContext.getCurrentInstance().addMessage(null,
				new FacesMessage(FacesMessage.SEVERITY_ERROR, "Caminho nÃo encontrado!", "Erro"));
	} catch (IOException ex) {
		Logger.getLogger(FuncionarioController.class.getName()).log(Level.SEVERE, null, ex);
		FacesContext.getCurrentInstance().addMessage(null,
				new FacesMessage(FacesMessage.SEVERITY_ERROR, "Erro ao criar arquivo!", "Erro"));
	}
}


 private String getNumeroRandomico() {
        int i = (int) (Math.random() * 10000);
        return String.valueOf(i);
    }
 O problema é quando vou tirar foto e ele acessa o método capturar nesta linha  String newFoto = servletContext.getRealPath("") + "resources" + File.separator + "upload" + File.separator + this.fotoCapturada;

Ele da este erro "Source not found"
Por favor alguém pode ajudar

Fiz algumas alterações no código e agora está com este erro:

    Não importa o caminho que eu coloque sempre acontece este erro, ele precisa de algum .jar especifico?

Mike · Dezembro 12, 2018, 9:37am

A exceção é clara.
Esta dando FileNotFoundException, ou seja, arquivo não encontrado

Tem certeza que é esse o caminho? Com duas vezes o C:?

waguener · Dezembro 12, 2018, 9:42am

Exatamente, ele mostra isso independente oque eu coloque nele veja a classe:
public void capturar(CaptureEvent captureEvent) {

    fotoCapturada = "capturada" + getNumeroRandomico() + ".png";
        
    String newFoto = servletContext.getRealPath("") + File.separator + "photocam" + File.separator + fotoCapturada ;
    criaArquivo(newFoto, captureEvent.getData());
   
}

Mike · Dezembro 12, 2018, 9:49am

Você chegou a printar a variável arquivo do método criaArquivo?

Não deveria ter um File.separator antes de resources?

String newFoto = servletContext.getRealPath("") + "resources"

servletContext.getRealPath() retorna o que?

Eu lembro que com externalContext as imagens eram apagadas quando o servidor reiniciava, ai foi necessário salvar em uma pasta fora do projeto e utilizar a classe StreamedContent para ler essa imagem e então referenciar o streamedContent no p:graphicImage

waguener · Dezembro 12, 2018, 9:54am

Amigo consegui salvar a imagem no diretório fiz o seguinte:
Baixei o primefaces6.0_source.jar que não estava no projeto com isso ele parou de mostrar o caminho duas vezes, depois criei a pasta photocam nesse caminho C:\Users\Wagner\eclipse-workspace.metadata.plugins\org.eclipse.wst.server.core\tmp4\wtpwebapps\Integra_olgber\photocam.
Como estava mostrando ele não encontrava esta pasta, criando manualmente o problema foi resolvido.

waguener · Dezembro 12, 2018, 11:44am

Precisei dar um clean no projeto agora não está funcionando, voltei pra estaca zero. Essa linha deveria criar as pastas certo
"String newFoto = servletContext.getRealPath("") + File.separator + “imagens” + File.separator + “tmp” + File.separator + fotoCapturada;"
Se alguém tiver um outro exemplo para capturar imagens com jsf por favor poderia me mostrar

waguener · Dezembro 12, 2018, 3:19pm

Realmente agora não sei por que parou de chamar o método para capturar imagem segue o codígo:
Web cam -
<p:dialog widgetVar=“dialogCamera” resizable=“false” id="camera"
position=“center” showHeader=“true” modal=“true” header=“Web Cam”>

					<p:photoCam widgetVar="photoCam" 
						listener="#{funcionarioController.capturar}"
						update="painel" />
						
					<p:commandButton value="Capturar" 
						onclick="PF('photoCam').capture();" process="@this" 
                                                  onsuccess="PF('dialogCamera').hide()" />
			
					<p:commandButton value="Fechar" type="button"
					onclick="PF('dialogCamera').hide()" />
					
			</p:dialog>

Controller -

public void capturar(CaptureEvent captureEvent) {

	System.out.println("Iniciar Captura");
	
	fotoCapturada = "capturada" + getNumeroRandomico() + ".png";
	servletContext = (ServletContext) FacesContext.getCurrentInstance().getExternalContext().getContext();
	String newFoto = servletContext.getRealPath("") + File.separator + "resources" + File.separator + "imagens"
			+ File.separator + fotoCapturada;
	
	System.out.println("Criando Arquivo");
		
	criarArquivo(newFoto, captureEvent.getData());
	System.out.println("Arquivo Criado");
}

public void criarArquivo(String arquivo, byte[] dados) {
	
	FileImageOutputStream imageOutput;
	try {
		imageOutput = new FileImageOutputStream(new File(arquivo));
		imageOutput.write(dados, 0, dados.length);
		imageOutput.close();

	} catch (FileNotFoundException ex) {
		Logger.getLogger(FuncionarioController.class.getName()).log(Level.SEVERE, null, ex);
		FacesContext.getCurrentInstance().addMessage(null,
				new FacesMessage(FacesMessage.SEVERITY_ERROR, "Caminho não encontrado!" + ex, "Erro"));
	} catch (IOException ex) {

		FacesContext.getCurrentInstance().addMessage(null,

	}

}

private String getNumeroRandomico() {
	int i = (int) (Math.random() * 10000);

Essa linha no caso define o caminho da pasta.

Deve ser pq no botão Capturar você colocou process="@this" e eu imagino que você queira processar a photoCam junto

Pois é também pensei nisso mas deixei assim:
<p:dialog widgetVar=“dialogCamera” resizable=“false” id="camera"
position=“center” showHeader=“true” header=“Web Cam”>

				<p:photoCam widgetVar="photoCam"
					listener="#{funcionarioController.capturar}" update="painel" />
				
				<p:panelGrid columns="2" layout="grid" style="padding:10px"
					columnClasses="ui-grid-col-6,ui-grid-col-6"
					styleClass="panelgrid-noborder">
					
					<p:commandButton value="Capturar"
						onclick="PF('photoCam').capture();" process="camera"
						oncomplete="PF('dialogCamera').hide()" />

					<p:commandButton value="Fechar" type="button"
						onclick="PF('dialogCamera').hide()" />
						
				</p:panelGrid>
			</p:dialog>

Mesmo erro ainda

Bom dia, consegui fazer funcionar a dúvida agora é sobre as imagens capturadas, como remove-las depois de usar ou seja não queria deixar lixo na pasta que estão sendo alocadas.
