我正在使用PrimeFaces 5.3、JSF 2.2和Omnifaces 2.3创建一个应用程序。
我正在使用jdk v8、Glassfish 4.1.1和MySQL 5。
为了从安全角度提供更多信息，我正在使用OWASP ZAP应用程序。
问题是我遇到了一些“内存不足-JavaHeapSpace”问题。

如果我等待几分钟，就会看到这些日志

我的猜测与图像管理有关。我正在使用从数据库检索的图像，并采用我曾经看到过的facelets实现方法。
<p:graphicImage value="#{applicationScopedBean.imagesFromDb}">
<f:param name="imageId" value="#{actualAd.favouriteImageId}" />
<f:param name="cvlTimeStamp" value="#{now}" />
</p:graphicImage>
应用范围的 Bean
public StreamedContent getImagesFromDb() {
FacesContext context = FacesContext.getCurrentInstance();
if (context.getCurrentPhaseId() == PhaseId.RENDER_RESPONSE) {
return new DefaultStreamedContent();
} else {
String imageId = context.getExternalContext().getRequestParameterMap().get("imageId");
return new DefaultStreamedContent(new ByteArrayInputStream(advertisingImageManager.getById(Long.valueOf(imageId)).getContent()));
}
}
我已经尝试了Omnifaces方法，但没有成功。 Facelets。
<o:graphicImage value="#{applicationScopedBean.getImageById(actualAd.favouriteImageId)}" class="img" lastModified="#{now}"/>
应用程序作用域的bean
public byte[] getImageById(Long imageId){
return advertisingImageManager.getById(imageId).getContent();
}
问题不是“我该如何解决这个问题”，而首先应该探究OWASP ZAP应用程序创建的这个问题是否正确。 如果是，我应该从哪里开始调查？
