Hi Andy,
Thanks for adding this to Jira.
See below my code what I have produced so far. The problem is that I now see
the complete filepath in my html source (<img src="
C:/tmp/pictures/8/71/1001/thumb1.jpg" alt=""/>)
I don't want the complete file url in my html source. How can I fix this.
And how do I map the html url to the file url?
The last problem is that the file url is correct, but the image is not shown
in my html page.
What am I doing wrong?
--Quick Example Code Below---
<img src="${ThumbnailPath}" alt="" />
public String getThumbnailPath() {
Asset asset = assetSource.getAsset(null,
"file:/8/71/1001/thumb1.jpg", null);
return asset.toClientURL();
}
public class FileSystemResource extends AbstractResource {
private static final int PRIME = 37;
public FileSystemResource(String path) {
super(path);
}
@Override
protected Resource newResource(String path) {
return new FileSystemResource(path);
}
@Override
public URL toURL() {
String filePath = getPath();
File file = new File(filePath);
if (file != null && file.exists()) {
try {
return file.toURL();
}
catch (MalformedURLException ex) {
throw new RuntimeException(ex);
}
}
return null;
}
}
public class FileSystemAssetFactory implements AssetFactory {
private static final String assetPath = "/images/";
public FileSystemAssetFactory() {
}
@Override
public Resource getRootResource() {
return new FileSystemResource("C:/tmp/pictures/");
}
@Override
public Asset createAsset(final Resource resource) {
final String filePath = resource.getPath();
return new Asset()
{
public Resource getResource()
{
return resource;
}
public String toClientURL()
{
return filePath;
}
/**
* Returns the client URL, which is essiential to allow informal
parameters of type
* Asset to generate a proper value.
*/
@Override
public String toString()
{
return toClientURL();
}
};
}
}
//In AppModule.java
public AssetFactory buildfileSystemAssetFactory() {
return new FileSystemAssetFactory();
}
public void contributeAssetSource(MappedConfiguration<String,
AssetFactory> configuration,
@InjectService("fileSystemAssetFactory") AssetFactory
fileSystemAssetFactory) {
configuration.add("file", fileSystemAssetFactory);
}
