We are building the following method that copies values from one entity to another and then persists the changes which works fine for us.
private void copyProperties(E orig, E dest) {
try {
for (Field origField : orig.getClass().getDeclaredFields()) {
try {
origField.setAccessible(true);
Object value = origField.get(orig);
if (value != null) {
Field destField = dest.getClass().getDeclaredField(origField.getName());
destField.setAccessible(true);
destField.set(dest, value);
}
} catch (IllegalAccessException | NoSuchFieldException ex) {
System.out.println("IllegalAccessException ");
ex.printStackTrace();
}
}
} catch (SecurityException ex) {
System.out.println("SecurityException ");
ex.printStackTrace();
}
}
But now we need to update only the properties that have present a specific annotation called #updatable.
#Documented
#Target({ElementType.FIELD, ElementType.TYPE_USE})#Retention(RetentionPolicy.RUNTIME)public #interface Updatable {
#Nonbindingboolean nullable() default false;
}
private void copyProperties(E orig, E dest) {
try {
for (Field origField : orig.getClass().getDeclaredFields()) {
Updatable annotation = origField.getAnnotation(Updatable.class);
if (annotation != null) {
System.out.println("Field "+origField.getName()+" annotation present");
try {
origField.setAccessible(true);
Object value = origField.get(orig);
if (value != null || annotation.nullable()) {
Field destField = dest.getClass().getDeclaredField(origField.getName());
destField.setAccessible(true);
destField.set(dest, value);
}
} catch (IllegalAccessException | NoSuchFieldException ex) {
System.out.println("IllegalAccessException ");
ex.printStackTrace();
}
}
}
} catch (SecurityException ex) {
System.out.println("SecurityException ");
ex.printStackTrace();
}
}
The problem is that when we analyze the annotation and return by reference the destination entity with the updated properties, the merge method in quarkus does not detect the changes.
I have the following class which has multiple custom ThreadPoolTaskExecutors I am showing it with one in this example.
#Configuration
#EnableAsync
public class ExecutorConfig {
#Bean(name = "streetCheckerExecutor")
public Executor getStreetAsyncExecutor() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(50);
executor.setQueueCapacity(1000000);
executor.setThreadNamePrefix("streetCheckerExecutor-");
executor.initialize();
return executor;
}
}
I have the following class which gets content from the database, I want to be able to check the queue size of streetCheckerExecutor and if it's less than a certain number, to add the content to the queue
#Component
public class StreetChecker {
#Autowired
StreetRepository streetRepository;
#Autowired
StreetCheckService streetChecker;
#EventListener(ApplicationReadyEvent.class)
public void checkStreets() {
try {
List<Street> streetList = streetRepository.getStreets();
for (int i = 0; i < streetList.size(); i++) {
streetChecker.run(streetList.get(i));
}
} catch (Exception e) {
e.printStackTrace();
} finally {
System.out.println("---------------------");
}
}
}
And below is the worker class
#Component
public class StreetCheckService {
#Async("streetCheckerExecutor")
public void run(Content content) {
try {
//do work
} catch (Exception e) {
e.printStackTrace();
} finally {
}
}
}
I am working with a lot of data and I don't want to grab everything from the database every time, but I want to check the queue size of streetCheckerExecutor and if it's less than a number, I want to get more content from the database and add it to the streetCheckerExecutor queque
Below is how I'm thinking I can do it by converting the above checkStreets to the one below
#EventListener(ApplicationReadyEvent.class)
public void checkStreets() {
while (true) {
try {
// check the queue size of streetCheckerExecutor
// if less than a number
// add to the queue
// else keep waiting and will try again in X minutes
} catch (Exception e) {
} finally {
try {
Thread.sleep(1000 * 60);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
But how would I be able to get the size of the queue in the checkStreets() method?
You can just autowire in your ThreadPoolTaskExecutor and get the queue with getThreadPoolExecutor().getQueue().
#Autowire
#Qualifier("streetCheckerExecutor")
private Executor streetExecutor;
#EventListener(ApplicationReadyEvent.class)
public void checkStreets() {
while (true) {
try {
final BlockingQueue<Runnable> queue = streetExecutor.getThreadPoolExecutor().getQueue();
if(queue.size() <= 5) {
queue.add(() -> {
final List<Street> streetList = streetRepository.getStreets();
streetList.forEach(street -> {
streetChecker.run(street);
});
});
}
} catch (Exception e) {
} finally {
try {
Thread.sleep(1000 * 60);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
i'm not sure this is what you meant, but something like this maybe.
I'm writing an app with Tango and getting a strange bug.

I have been plagued by this problem for three days.I need a hero.Thanks everyone.
Notes:The rear camera is not be used for tango because i use it elsewhere.
I had the same problem. For me the solution was to request permissions:
startActivityForResult(
Tango.getRequestPermissionIntent(Tango.PERMISSIONTYPE_MOTION_TRACKING),
Tango.TANGO_INTENT_ACTIVITYCODE);
How can i get list of tiket with its categories through Jpa Specification
Example model:
#Entity
#Table(name = "tickets")
public class Ticket {
#Id
private Integer id;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "category_id")
private Category
}
Method of service:
public Page<Ticket> findAll(Pageable pageable) {
return ticketRepository.findAll((root, query, cb) -> {
root.join("category");
return query.getRestriction();
}, pageable);
}
I was able to eager load the collection by using a fetch instead of a join.
public Page<Ticket> findAll(Pageable pageable) {
return ticketRepository.findAll((root, query, cb) -> {
root.fetch("category");
return query.getRestriction();
}, pageable);
}
The fetch method will use the default join type (inner). If want to load tickets with no category, you'll have to pass JoinType.LEFT as the second parameter.
as they say, stackoverflow giveth, stackoverflow taketh..

modify it as you see fit.. the method you'll call is "eagerizeUnsafe".
YMMV, but this should to the trick to eagerize all the collections of a lazily initialized bean.
what i am trying to do is that on click of a button in screen1, i try push the screen2 repeatedly with different images and different Transition Context.
the code is as follows
public void fieldChanged(Field field, int context)
{
if(field==slideButton)
{
for(int i=0;i<bitmaps.length;i++)
{
slideScreen = new SliderScreen(bitmaps[i]);
UiApplication.getUiApplication().pushScreen(slideScreen);
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
UiApplication.getUiApplication().popScreen(slideScreen);
}
}
}
}
Problem is that nothing appears.Is there any other way to achieve this..
Fixed version of your initial idea:
public void fieldChanged(Field field, int context) {
if (field==slideButton) {
final UiApplication app = UiApplication.getUiApplication();
new Thread(new Runnable() {
public void run() {
for (int i = 0; i < bitmaps.length; i++) {
final SliderScreen slideScreen =
new SliderScreen(bitmaps[i]);
app.invokeAndWait(new Runnable() {
public void run() {
app.pushScreen(slideScreen);
}
});
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
app.invokeAndWait(new Runnable() {
public void run() {
app.popScreen(slideScreen);
}
});
}
}
}).start();
}
}
Your code did not work because the UI thread was sleeping between push and pop, so it has no time/chance to start drawing the screen. Note I moved the entire action into a separate thread. So now the main UI thread has free time to actually make drawing.
