I have a question for the developers of Spring Web MVC. In a nutshell: previously it was possible to send a request body in an HTTP DELETE message, but now it is not possible anymore. Why? In detail: We are using spring-webmvc-4.2.4.RELEASE . @RestController public class Controller { @RequestMapping(value = "/{pathVariable}/deleteAnything", method = RequestMethod.DELETE) public R
我对Spring Web MVC的开发者有个疑问。 简而言之：之前可以在HTTP DELETE消息中发送请求主体，但现在不可能了。 为什么？ 详细： 我们使用的是spring-webmvc-4.2.4.RELEASE 。 @RestController public class Controller { @RequestMapping(value = "/{pathVariable}/deleteAnything", method = RequestMethod.DELETE) public ResponseEntity<?> deleteAnything(@PathVariable String pathVariable,
After reading several documentation pages of Apache Flink (official documentation, dataartisans) as well as the examples provided in the official repository, I keep seeing examples where they use as the data source for streamming a file already downloaded, connecting always to the localhost. I am trying to use Apache Flink to download JSON files which contain dynamic data. My intention is to t
在阅读了Apache Flink（官方文档，dataartisans）的几个文档页面以及官方存储库中提供的示例之后，我一直看到它们用作数据源的示例，用于流式处理已下载的文件，并始终连接到本地主机。 我正在尝试使用Apache Flink下载包含动态数据的JSON文件。 我的目的是试图建立我可以访问JSON文件作为Apache Flink的输入源的URL，而不是使用其他系统下载并使用Apache Flink处理下载的文件。 是否有可能建立与Apache Flink的这个网络连
I'm doing unit test for mapping classes but each time it shows me NullPointerException @Mapper(componentModel = "spring") public abstract class CountryMapper implements EntityMapper<CountryDTO, Country> { static final public CountryMapper INSTANCE = Mappers.getMapper(CountryMapper.class); @Autowired CountryRepository countryRepository; Country fromId(Long id) { if (id ==
我为映射类进行单元测试，但每次它都会显示我NullPointerException @Mapper(componentModel = "spring") public abstract class CountryMapper implements EntityMapper<CountryDTO, Country> { static final public CountryMapper INSTANCE = Mappers.getMapper(CountryMapper.class); @Autowired CountryRepository countryRepository; Country fromId(Long id) { if (id == null) { return null;
I have following method in my service to mock AWS sqs @Override public Message recieveMessage(String queueUrl) { Objects.requireNonNull(queueUrl); ReceiveMessageRequest request = new ReceiveMessageRequest().withQueueUrl(queueUrl).withMaxNumberOfMessages(1); ReceiveMessageResult receiveMessageResult = this.sqsClient.receiveMessage(request); // As per the spec, we need to return on
我在服务中使用以下方法来模拟AWS sqs @Override public Message recieveMessage(String queueUrl) { Objects.requireNonNull(queueUrl); ReceiveMessageRequest request = new ReceiveMessageRequest().withQueueUrl(queueUrl).withMaxNumberOfMessages(1); ReceiveMessageResult receiveMessageResult = this.sqsClient.receiveMessage(request); // As per the spec, we need to return only one message.
I try to verify logger message with mokito. However, I can not run my junit class to coverage all lines of code. Do you the reason? My code: public class App { private static final Logger LOGGER = Logger.getLogger(App.class); public List<String> addToListIfSizeIsUnder3(final List<String> list, final String value) { if (list == null) { LOGGER.erro
我尝试用mokito验证记录器消息。 但是，我无法运行我的junit类来覆盖所有代码行。 你是这个原因吗？ 我的代码： public class App { private static final Logger LOGGER = Logger.getLogger(App.class); public List<String> addToListIfSizeIsUnder3(final List<String> list, final String value) { if (list == null) { LOGGER.error("A null list was passed in");

We're trying to use the LinkedDataSailGraph along with Gremlin to do some funky stuff with traversals, inference. Unfortunately, just instantiating the class causes this error. Any ideas? new LinkedDataSailGraph(new MemoryStoreSailGraph()); java.lang.RuntimeException: No parser factory available for RDF format JSON-LD (mimeTypes=application/ld+json; ext=jsonld) at com.tinkerpop.blueprin
我们试图使用LinkedDataSailGraph和Gremlin一起做遍历，推理的一些时髦的东西。 不幸的是，仅仅实例化这个类会导致这个错误。 有任何想法吗？ new LinkedDataSailGraph(new MemoryStoreSailGraph()); java.lang.RuntimeException：没有解析器工厂可用于RDF格式JSON-LD（mimeTypes = application / ld + json; ext = jsonld）at com.tinkerpop.blueprints.impls.sail.impls.LinkedDataSailGraph.createSail（LinkedDataSail

I'm struggling with EasyMock. I've written two small classes to illustrate my problem: public abstract class A { private AtomicReference<Integer> id = new AtomicReference<Integer>(null); public final int getId() { return id.get(); } public final boolean setId(int id) { return this.id.compareAndSet(null, id); } } public class B extends A {
我正在与EasyMock苦苦挣扎。 我写了两个小类来说明我的问题： public abstract class A { private AtomicReference<Integer> id = new AtomicReference<Integer>(null); public final int getId() { return id.get(); } public final boolean setId(int id) { return this.id.compareAndSet(null, id); } } public class B extends A { } 然后我继续写下如下测试方法： pub
I'm trying to find a simple solutions to generate markup in a JSP page that needs to be reused within that page. The templated markup would have scriptlet calls within it, with some localized Java declarations. For example: <markup> <% MyObject localObject = controller.getMyObject(); %> <name><%= localObject.getName() %></name> <value><%= localObjec
我试图找到一个简单的解决方案来在JSP页面中生成需要在该页面内重用的标记。 模板化的标记会在其中包含scriptlet调用，以及一些本地化的Java声明。 例如： <markup> <% MyObject localObject = controller.getMyObject(); %> <name><%= localObject.getName() %></name> <value><%= localObject.getValue() %></value> </markup> 我希望能够在JSP文件中多次重复使
