annotations

问题 I need to disable @NonNull/@Nullable annotations in Kotlin generated Java code because some annotation adapters (code generators) cant handle properly some annotated fields Do you know how it could be done? Some Kotlin annotation or compilator directive Problem: kotlin class: open class TestModel( var test: ByteArray = ByteArray(0) ) generated java: public class TestModel { @org.jetbrains.annotations.NotNull() private byte[] test; @org.jetbrains.annotations.NotNull() public final byte[]

问题 I have this code: public static void main(String[] args) { testAnnotation(); } @RetryOnFailure(attempts = 2) public static void testAnnotation() { System.out.println("enter here"); int x = 1/0; } But it runs the function just one time. This is the output: enter here Exception in thread "main" java.lang.ArithmeticException: / by zero at Main.testAnnotation(Main.java:16) at Main.main(Main.java:10) This my pom: <dependency> <groupId>com.jcabi</groupId> <artifactId>jcabi-aspects</artifactId>

问题 I would like to have some function applied to fields in a case class, that are annotated with MyAnnotation . The idea is to transform type T into its generic representation, extract annotations, zip, fold right (or left) to reconstruct a generic representation and finally get back to type T . I followed the answer provided here and this gist. I'm using scala 2.11.12 and shapeless 2.3.3. Hereafter is my code: import shapeless._ import shapeless.ops.hlist._ case class MyAnnotation(func: String)

问题 I have a problem with my code. I want to test some elements on a website but after run the tests, TestNG throws the error: "No tests were found". I have already tried to create a new testng.xml but it doesn't work. package tests; import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.support.FindBy; import org.openqa.selenium.support.PageFactory; import org.testng

问题 I am using Android studio 3.3 and trying to use Dagger2 in my project. However, the annotation processing does not work in it and the annotation classes are not generated. I am add the library as follows to my gradle file. implementation 'com.google.dagger:dagger:2.21' annotationProcessor 'com.google.dagger:dagger-compiler:2.21' I have also specified the annotationProcessorOptions javaCompileOptions { annotationProcessorOptions { includeCompileClasspath true } } What have I tried: Closing the

问题 I'm using an XYBoxAnnotation to demarcate a rectangular area on a JFreeChart. I would like one side of the box to be "open", i.e go out to infinity. I tried setting the value to Double.POSITIVE_INFINITY but this did not seem to work. I also tried setting it to Double.MAX_VALUE , with no luck either. In these cases, the annotation doesn't even show up on the plot at all. And there are no exceptions thrown. Below is a very simple version of my code in which I generate the XYBoxAnnotation and

问题 I'm wondering whether it is possible to add additional functionality to the @Column annotation in JPA. Specifically, what I would like to do is tag columns of sensitive data with an @ProtectedColumn annotation: this would then tell the persistence framework to apply some type of data protection (encryption, tokenization, whatever...) to the values when storing them into the actual data store, and then reverse that process when reading the values from the data store. So I might have a Customer

问题 I have controller like @MessageMapping("/room.register") @SendTo("#{sendTo}") public Message addUser(@Payload Message message, SimpMessageHeaderAccessor headerAccessor) { headerAccessor.getSessionAttributes().put("username", message.getSender()); return message; } And i want to change value of SendTo annotation in runtime. I tried to do it as follows: @Aspect public class SendToAspect { @Autowired private WebSocketConfigurationProperties webSocketConfigurationProperties; @Around("execution

问题 I'm working on a sudoku solving application and i dont want to write a code such as Method(int[] i) { if(i.length == 9) { // do stuff } else { // throw... } } is there any way to enforce arrays parameter to be exact 9 integer by using annotations such as Method(@SizeNine int[] i) { //do stuff } 回答1: Yes, this is possible, using a compiler plugin. Use the @ArrayLen annotation to declare a method whose argument must be a length-9 array of Strings: void myMethod(String @ArrayLen(9) [] a) { ... }

问题 I'm writing a method supposed to retrieve all annotations of a specific method declaring class and its superclasses. By using the method getAnnotations() on the declaring class, the resulting table contains only the declaring class annotations and the superclass annotations are ignored. If I remove the annotations of the declaring class, then the superclass annotation are present. What am I missing here? The simplified method retrieving the annotations : public void check(Method invokedMethod
