问题 I am trying to process a tree of data objects. Each tree leaf is supposed to be processed through a function using a coroutine. The whole process should be done using a fixed size threadpool. So I came up with this: val node = an instance of WorkspaceEntry (tree structure) val localDispatcher = newFixedThreadPoolContext(16) fun main() { val job = SupervisorJob() val scope = CoroutineScope(localDispatcher + job) handleEntry(node, scope) runBlocking { job.join() } } The handleEntry method

问题 Here is my Code that for Volley Request:- val searchRequest = object : JsonArrayRequest(Request.Method.GET,url, Response.Listener { response -> val result = response.toString() }, Response.ErrorListener { error -> Toast.makeText(activity, "Error!",Toast.LENGTH_LONG) .show() Log.d("ERROR",error.toString()) }) { override fun getBody(): ByteArray { // TODO add Body, Header section works ////////// return super.getBody() } override fun getBodyContentType(): String { return "application/json" }

问题 I am using espresso and I want to create a mock response for the content resolver. When I use: `when`(context.activity.contentResolver.query( ArgumentMatchers.isA(Uri::class.java), ArgumentMatchers.isA(Array<String>::class.java), ArgumentMatchers.anyString(), null, null)) .thenReturn(matrixCursor) I get the error: java.lang.NullPointerException: uri at com.android.internal.util.Preconditions.checkNotNull(Preconditions.java:128) Is it possible to create the mock response for the content

问题 I'm using Postman to test a simple OAuth2 API I'm creating in Spring Boot 2.2.6 with Spring Security. I successfully receive a JWT when requesting new user credentials, but all of my endpoints return a 403 Forbidden error when I attempt to access them with this token in my headers. My classes are as follows: My server security configuration: @Configuration @EnableWebSecurity @Order(1) @EnableGlobalMethodSecurity(prePostEnabled = true, proxyTargetClass = true) class ServerSecurityConfiguration

问题 While taking a look at this question, I noticed that applying @Throws to a get or set use-site has no effect. Additionally, the only valid targets for @Throws are AnnotationTarget.FUNCTION , AnnotationTarget.PROPERTY_GETTER , AnnotationTarget.PROPERTY_SETTER , and AnnotationTarget.CONSTRUCTOR . Other annotations, such as the JPA annotations and Deprecated work fine and are properly applied to the method! This is strange behavior. To demonstrate, I created a simple abstract class in Java, with
