Como pegar uma imagem no MySQL e exibi-la em uma page JSF?

Programação Java

#21

Com o PrimeFaces é tranquilo, é a biblioteca mais completa pra JSF e ACHO que é a biblioteca de componentes mais completa de todas as linguagens.

Você tem duas maneiras de usar o p:graphicImage, uma que é referenciando a imagem da pasta resources e outra é apontar um obj StreamedContent para o atributo value

<p:graphicImage value="#{bean.meuStreamedContent}" />

StreamedContent é uma interface que tem o propósito de representar um arquivo seu, no caso a imagem.

A gente não pode instanciar uma interface, mas podemos utilizar polimorfismo para referenciar uma classe que implementa StreamedContent, assim:

StreamedContent streamedContent = new DefaultStreamedContent(new ByteArrayInputStream(byteArray));

O construtor de DefaultStreamedContent aceita qualquer classe que seja uma inputStream

muito Obrigado mais uma vez mike, vou tentar aqui e aviso se der certo!

Magina :+1:

O p:graphicImage com DefaultStreamedContent tem um problema em relação ao ciclo de vida, então da uma olhada abaixo com atenção, caso você tenha algum problema talvez isso ajude

The <p:graphicImage> will call the getter method twice. First time is when the element is to be rendered to HTML and thus requires an URL in the src attribute. If you just return new DefaultStreamedContent(), then it will autogenerate the right URL in src attribute. Second time is when the browser really requests the image, this is the moment when you should return the actual image.

So, the getter method should basically look like this:

public StreamedContent getStreamedImageById() {
    FacesContext context = FacesContext.getCurrentInstance();

    if (context.getCurrentPhaseId() == PhaseId.RENDER_RESPONSE) {
        // So, we're rendering the view. Return a stub StreamedContent so that it will generate right URL.
        return new DefaultStreamedContent();
    }
    else {
        // So, browser is requesting the image. Get ID value from actual request param.
        String id = context.getExternalContext().getRequestParameterMap().get("id");
        Image image = service.find(Long.valueOf(id));
        return new DefaultStreamedContent(new ByteArrayInputStream(image.getBytes()));
    }
}

Peguei isso do stackoverflow em um post do BalusC

eu estou tentando fazer da primeira forma, e nao ta dando certo, a imagem do banco nao vem. o console apresenta o seguinte erro.

08:00:22,671 WARN PageNotFound:1248 - No mapping for GET /intranet/uploadFileBean.getImage

fiz da seguinte forma:

bean
public void getImage() {
sc = new DefaultStreamedContent(new ByteArrayInputStream(uploadArquivoService.findById(3).getArquivo()));

}

<h:form>
<h:panelGrid>

							<p:graphicImage value="uploadFileBean.sc"></p:graphicImage>

						</h:panelGrid>

					</h:form>
#25

Não deveria ser uma EL?

<p:graphicImage value="#{uploadFileBean.sc}"></p:graphicImage>

é isso mesmo, mas agora ele me apresentou o seguinte erro

@Mike

pq quando ponho o Objeto StreamedContent em uma Lista ele nao funciona mais?

					<h:form id="form-imagens">
						<div class="table-responsive">
							<h:dataTable id="tabela"
								rendered="#{not empty uploadFileBean.streamedContentList}"
								value="#{uploadFileBean.streamedContentList}" var="c"
								styleClass="table table-hover table-sm" width="100%">
								<h:column>
									<f:facet name="header">IMAGEM</f:facet>
                                   <p:graphicImage value="#{c}"></p:graphicImage>
                                </h:column>
								
							</h:dataTable>
						</div>
						
					</h:form>

Da uma olhada nesse post (que é o que eu postei antes)

Tem um workaround, basicamente você terá que ver em que fase o ciclo de vida esta e então retornar o streamedContent]

No exemplo do post, o cara passou o indentificador da imagem através de f:param e então pegou no método

<p:graphicImage id="photo" value="#{registrarPedidoController.streamedImageById}" cache="FALSE">
    <f:param name="inv" value="#{inv.id}" />
</p:graphicImage> 
String id = context.getExternalContext().getRequestParameterMap().get("id"); 
Image image = service.find(Long.valueOf(id));
return new DefaultStreamedContent(new ByteArrayInputStream(image.getBytes()));

Mike, desculpa nao entendi a explicação do cara, nem a tratativa dele :sob::sob::sob:, vc conseguiu entender o que ele fez pras imagens aparecerem na lista p:datable?

#37

O p:graphicImage chama o método duas vezes durante o ciclo de vida, ai você tem que verificar em qual fase do ciclo de vida esta, dependendo da fase você retorna a imagem, que é o que cara fez:

public StreamedContent getStreamedImageById() {
    FacesContext context = FacesContext.getCurrentInstance();

    if (context.getCurrentPhaseId() == PhaseId.RENDER_RESPONSE) {
        // So, we're rendering the view. Return a stub StreamedContent so that it will generate right URL.
        return new DefaultStreamedContent();
    }
    else {
        // aqui esta pegando o parametro passado através de f:param, o f:param funciona como um map (chave e valor)
        String id = context.getExternalContext().getRequestParameterMap().get("id");
        Image image = service.find(Long.valueOf(id));
        return new DefaultStreamedContent(new ByteArrayInputStream(image.getBytes()));
    }
}

Em f:param ele passou um valor para a requisição e então pegou esse valor no bean.
Esse valor é a própria identificação da imagem (valor único, que no caso é o id)

Você deve ter alguma maneira de especificar qual imagem quer através de um valor, que foi o que ele fez

<p:dataTable id="table-cardapio" var="cardapio" value="#{cardapioBean.cardapios}">                          
    <p:column>
        <p:graphicImage id="photo" value="#{registrarPedidoController.streamedImageById}" cache="FALSE">
            <f:param name="id" value="#{cardapio.id}" />
        </p:graphicImage>                                
    </p:column>
</p:dataTable>

No código acima foi passado um parâmetro com o nome id e o valor é o id do objeto, mas poderia ser qualquer nome e qualquer atributo, mas eu entendo que o id é um valor único, então usei ele.

O value do graphicImage vai chamar um método que retorna um streamedContent, e dentro desse método vai pegar o parâmetro passado e buscar a imagem no banco através desse parâmetro (primeiro código postado)

EDIT: Da uma olhada ai e se não conseguir posta como o seu código esta e o erro

[RESOLVIDO]Galleria primefaces 6.1 não exibe as imagens!
#38

entendi! e seu eu nao quiser especificar qual item eu quero pegar, e sim quiser buscar toda uma lista de imagens também deverá funcionar??

#39

Funciona, só que ai você vai precisar fazer a mesma tratativa de ciclo de vida de qualquer jeito

Certo! ficou assim minha tratativa

eu retorno uma lista vazia caso caia dentro do IF
