We are creating a base action to manage export function. This base class deals
with file name and content type.
public class public abstract class AbstractExportAction{ //Will be override
protected abstract InputStream exportInputStream() ; @Action(value = "export",
results = { @Result(name = "success", type = "stream", params = { "inputName",
"inputStream", "contentType", "${exportContentType}; charset=UTF-8",
"Content-Disposition", "attachment; filename=\"${filename}\"",
"contentDisposition", "attachment; filename=\"${filename}\"", "bufferSize",
"2048" }) }) public String export() throws ClientException { inputStream =
exportInputStream(); LOG.debug("Exporting to {} file ", getFilename());
return SUCCESS; }
//setter getters for filename and exportContentType }
Now the other actions extend above class and return they own data as InputStream
package action.account;
public class AccountsSummary extends AbstractExportAction { @Override protected
InputStream exportInputStream() { } }
*We have /account/export.action without any need to deal with file name and
content *
Generally every thing works fine, but in below case, the export action will not
map to correct class:
* Action A extends AbstractExportAction
* Action B extends AbstractExportAction
* Action A and B are in same namespace (package)
In above case, struts ( struts convention plugin) randomly took one action A or
B and map export action to that class.
Do you think we are using correct approach?!
