Tratamento upload com tamanho maior que o limite

Referente ao curso VRaptor4: Alta produtividade com aplicações web em java

Boa noite.

Estou encontrando problemas para tratar os casos em que o arquivo enviado tem tamanho maior que o estabelecido na configuração de limites.

Quando o arquivo excede pouco o tamanho limite o validator.onErrorRedirectTo pega o erro e trata; porém, quando a diferença aumenta o sistema cai – ao menos no navegador recebo a mensagem de dizendo que houve falha no carregamento da página (Conexão reiniciada).

Segue a mensagem do debug pouco antes do lançamento da exceção:

19:02:08,656 DEBUG [CommonsUploadMultipartObserver] Setting file sizes: total=52428800, file=20971520
19:02:08,712 DEBUG [DefaultResult       ] including attribute vmessages: br.com.caelum.vraptor.validator.Messages@64c2b0e2
19:02:08,712  WARN [CommonsUploadMultipartObserver] There was some problem parsing this multipart request, or someone is not sending a RFC1867 compatible multipart request.
org.apache.commons.fileupload.FileUploadBase$FileSizeLimitExceededException: The field arquivo exceeds its maximum permitted size of 20971520 bytes.
    at org.apache.commons.fileupload.FileUploadBase$FileItemIteratorImpl$FileItemStreamImpl$1.raiseError(FileUploadBase.java:787)
    at org.apache.commons.fileupload.util.LimitedInputStream.checkLimit(LimitedInputStream.java:78)
    at org.apache.commons.fileupload.util.LimitedInputStream.read(LimitedInputStream.java:137)

Fiz a configuração dos tamanhos limites tanto como anotação no método:

@UploadSizeLimit(sizeLimit=40 * 1024 * 1024, fileSizeLimit=40 * 1024 * 1024)
public void adiciona(MaterialComplementar mc, UploadedFile arquivo) throws IOException {

Quanto pela classe de especialização:

@Specializes
@ApplicationScoped
public class CustomMultipartConfig extends DefaultMultipartConfig {

O erro é o mesmo.

Os testes estão bem enxutos, pra evitar qualquer dúvida não há nenhum código de salvamento do arquivo em arquivo ou banco. O problema ocorre antes disso. Segue o método do controller:

public void adiciona(MaterialComplementar mc, UploadedFile arquivo) throws IOException {

    if (arquivo == null) {
        validator.add(new SimpleMessage("arquivo", "Não foi informado um arquivo para upload"));
    }
    validator.onErrorRedirectTo(this).form();

    // ...

    result.redirectTo(this).form();
}

Nos últimos testes, o limite de tamanho por aquivo estava em 20M. Ao enviar um arquivo de 31M o validator tratou, já um de 39M deu zebra, a casa caiu.

Em suma : o validator não trata o erro.

Por favor mestres, uma ajuda.

Desde já agradeço.

Algumas outras informações importantes:

Versão do VRaptor: 4.2.0-RC3

commons-fileupload: 1.3.1

Java: 1.8.0_101

Oi Rodrigo, no lado do servidor aparece alguma mensagem relativa a memória ou algo parecido? Parece estranho que um aumento tão pequeno de tamanho derrube o servidor.

por Rodrigo Lourenço

Oi Alberto.

Não aparece nada referente a memória. No stacktrace consta que o tamanho foi ultrapassado, só. No fim da pilha de erros não aparece nenhuma mensagem mais significativa. Como eu disse, deixei o código super limpo pra não correr o risco de estar fazendo algo errado.

É Rodrigo, não estou conseguindo ver o problema não. Acho que eu precisaria rodar o código para testar... Em relação a saber se o servidor caiu mesmo, você precisa ver se seu tomcat, ou qq que seja o servidor, ainda está de pé depois do upload do arquivo maior.

Caso seja possível, posta o link do projeto no github.

Oi Rodrigo

Você consegue colocar o VRaptor e FileUpload como debug no log4j e mandar os logs dessa request aqui?

Se precisar, aqui tem um how to de como ativar os logs:

http://www.vraptor.org/en/docs/dependencies-and-prerequisites/#logging

Fora isso, fiquei na dúvida sobre uma coisa. A aplicação cai, ou só a request que termina lançando um 500?

por Rodrigo Lourenço

Oi Turini.

Coloquei VRaptor e FileUpload como DEBUG e gerei log para dois senários: um para o caso em que o validator trata o erro e redireciona para a página que solicitei (método form do controller corrente). O segundo para o caso em que o validator "não trata".

O problema ocorre no método "adiciona", que no final faz um redirect para "form". No segundo senário o redirect não acontece. O navegador não mostra aquela página clássica do HTTP Status 500). Mostra uma página informando que a conexão foi reiniciada (no Chrome: ERR_CONNECTION_RESET).

O senário é o seguinte: limitei o tamanho de arquivos para upload em 3Mb. Percebi que para aquivos de até 6Mb o erro é tratado e o redirecionamento ocorre como previsto. Com arquivos a partir de 8Mb a casa cai.

Segue os logs:

Senário 1:

Comparando os dois logs percebi no segundo não há uma parte que consta no primeiro. Me refiro ao trecho que começa a partir da seguinte linha:

ah, agora tudo faz sentido!

O Chrome: ERR_CONNECTION_RESET acontece pq o seu servidor está abortando o upload.

O tomcat tem um atributo chamado "maxSwallowSize" com o valor default bem pequeno:

The maximum number of request body bytes (excluding transfer encoding overhead) that will be swallowed by Tomcat for an aborted upload. An aborted upload is when Tomcat knows that the request body is going to be ignored but the client still sends it. If Tomcat does not swallow the body the client is unlikely to see the response. If not specified the default of 2097152 (2 megabytes) will be used. A value of less than zero indicates that no limit should be enforced.

Experimenta configurar um número maior e ver se funciona?

solução!

ps: eu nao consigo testar agora, mas acho que basta você colocar -1 (unlimited) no conf/server.xml de dentro do seu tomcat:

<Connector port="8080" protocol="HTTP/1.1"
    connectionTimeout="20000"
    redirectPort="8443" 
    maxSwallowSize="-1"/>

experimenta e nos diz se funcionou? Não esqueça de dar um clean em tudo antes de rodar (;

Cara, queria te dizer que funcionou, mas continua o mesmo erro.

ps: não esqueci do clean.

Turini, me perdoe o descuido no teste - devo ter feito algo errado na primeira tentativa. Tua sugestão foi a solução.

Como o fórum fica pra posteridade e possivelmente outros terão o mesmo problema, acho legal compartilhar uma questão sobre a configuração do Tomcat - nesse caso, para quem usa Eclipse. Por default a configuração dessa IDE diz que as configurações originais do Tomcat não serão alteradas, que será utilizada uma config específica para o workspace. Nesse caso, quanto a solução apresentada pelo Turini, seria necessário fazer o ajuste no server.xml que está nesse local. Um caminho aproximado ao que segue:

/<caminho>/workspace/Servers/<Tomcat v...>server.xml

Oi Rodrigo

Mil perdões pela demora, só cheguei na sua mensagem agora. Que bom que funcionou!

Obrigado com compartilhar essa informação adicional, sem dúvida será útil para mais alunos.

Um abraço e bons estudos
