<div class="paragraph">
<p>Servlets podem ser executado assincronamente - isso pode ser útil se seu servlet executa operações de longa execução, como chamar
outros serviços usando um cliente assíncrono.</p>
</div>
<div class="paragraph">
<p>Marque seu servlet como <code>asyncSupported</code> e chame Request.startAsync (). Isso retornará um objeto AsyncContext. Seu
Seu código precisará chamar AsyncContext.dispatch () quando terminar.s</p>

<div class="paragraph">
<p>AVISO:</p>
</div>
<div class="paragraph">
<p>A Seção 2.3.3.4 da Especificação do Servlet 3.0 diz "Além dos métodos startAsync e complete, não é garantido que as implementações dos objetos de solicitação e resposta sejam seguras contra threads. Isso significa que elas devem ser usadas apenas dentro do escopo da thread de manipulação de solicitações ou o aplicativo deve garantir que o acesso aos objetos de solicitação e resposta seja seguro para threads".</p>
</div>
<div class="paragraph">
<p>Se você escrever para a resposta diretamente do seu Runnable (nº 1 abaixo), você corre o risco de sofrer uma condição de execução com outra thread usando a resposta.
Isso é particularmente perceptível quando o Async solicita o tempo limite, pois os contêineres reciclam o objeto Request and Response para usar em outra solicitação.</p>
