I have a service to get the validator content as a string after passing the validator id (name). The validator's XSL files are placed in the src/main/resources. I am scanning the validator directory in the src/main/resources/de/validators to check if the file is a vailable. I am converting its input to a string and returning it as result fot the service.
In the findFile() method I want to leave the recursive call and the loop after finding the match. Is that possiable in my case?
Currently I am assigning the match to the fileName class attribute which works for me. A better approach would be to break the recursive call if it is possiable in my case.

I want to scrape the main content only of a web page by JSoup and save to a file.
Test web page:
https://netbasal.com/using-the-angular-http-client-in-angular-v15-f4bec3c11926
My test program use java 11, JSoup 1.15.3.
The output is missing:
the title "Using the Angular Http Client in Angular v15",
the source codes (by Github),
the heading "Interceptors in Lazy Loaded Modules".
How to modify the test program to add the missing content?

How could I get value based on a key from an XML content http enpoint, so it is something like
<authority.result result="found 7 matches" startToken="xxxxxxx">
<TestEntry keyId="0right0" test="test" valueId="rightValue123" version="1"/>
<TestEntry keyId="0wrong" test="test" valueId="0wrongValue" version="1"/>
<TestEntry keyId="0wrong0" test="test" valueId="wrong" version="1"/>
</authority.result>
I would like to get the valueId when keyId=="0right0" only, I previously wrote following but could not get value for a specific key.
URL url = new URL(endpoint);
XMLStreamReader reader = XMLInputFactory.newInstance().createXMLStreamReader(url.openStream());
String latest;
while (reader.hasNext()) {
if (reader.next() == XMLStreamConstants.START_ELEMENT) {
if (reader.getLocalName().equals("valueId")) {
latest = reader.getElementText();
return latest;
}
}
}
You need to distinguish XML element from an attribute. To read attribute name and value you have to use getAttributeName and getAttributeValue methods respectively.
Below you find example code how to read attributes:
import javax.xml.namespace.QName;
import javax.xml.stream.XMLInputFactory;
import javax.xml.stream.XMLStreamConstants;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamReader;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.Optional;
public class XmlStreamApp {
public static void main(String[] args) throws IOException, XMLStreamException {
...
XMLStreamReader reader = XMLInputFactory.newInstance().createXMLStreamReader(stream);
Optional<String> value = findValueForTestEntry(reader, "0right0");
System.out.println(value);
}
private static Optional<String> findValueForTestEntry(XMLStreamReader reader, String keyValue) throws XMLStreamException {
while (reader.hasNext()) {
if (reader.next() == XMLStreamConstants.START_ELEMENT) {
String localName = reader.getLocalName();
if ("TestEntry".equals(localName)) {
Optional<String> optionalValue = getValueForKey(reader, keyValue);
if (optionalValue.isPresent()) {
return optionalValue;
}
}
}
}
return Optional.empty();
}
private static Optional<String> getValueForKey(XMLStreamReader reader, String keyValue) {
String value = "";
boolean found = false;
for (int attr = reader.getAttributeCount() - 1; attr >= 0; attr--) {
QName attributeName = reader.getAttributeName(attr);
if (attributeName.getLocalPart().equals("keyId")) {
found = keyValue.equals(reader.getAttributeValue(attr));
}
if (attributeName.getLocalPart().equals("valueId")) {
value = reader.getAttributeValue(attr);
}
}
return found ? Optional.of(value) : Optional.empty();
}
}
Above code prints:
Optional[rightValue123]
You could use an xpath to get to the desired value :
string(//TestEntry[#keyId="0right0"]/#valueId)
I use Java mail APIs from a spring web application to send a weekly email to an outlook mail.
The feature was behaving normally for the first couple of weeks, then without any changes outlook received two emails, the next week three emails were received, then four, then five emails.
The logs set in the Java code indicates that only one email is being sent from the application.
I can't replicate the issue by changing the schedule to send each 15 minutes, or hour, or any shorter interval.

you might have duplicate entries on your argument emailAddresses, try moving it to treeset if you cant ensure duplicate entries from the repository layer
I have a scenario where to test the api using the payload coming from text file.Each line in file represents one payload.How can I dynamically generate test cases based on the above scenario.
I tried as below calling one test from other ,but i can only see paraent test passed.

How can i generate test cases dynamically by taking input from file?
If you can convert your file JUnitParams supports loading data from a CSV.
Using an example from the above link's repository:
public class PersonTest {
#Test
#FileParameters("src/test/resources/test.csv")
public void loadParamsFromCsv(int age, String name) {
assertFalse(age > 120);
}
}
I am completing my university project, but I encountered weird problem. Since I am a student, apologize in the adavance if it is prosaic.
I have my BasicCommonController which has List backendErrors = new ArrayList<>()
, and I have another Controller which extends BasicCommonController, and I'm able to access backendErrors list from BasicCommonController, but I am not able
to put new Element to the list, wchich is always empty. I have tried to access via super.backendErrors, but it also does not work.
How to add some error to the super.backendErrors and access it in another Controllers
this is abstract controller:
