我有这个未修饰的窗口:
public static void initStartPage(final Stage primaryStage) {
final Stage startPage = new Stage();
startPage.initStyle(StageStyle.UNDECORATED);
//startPage.initOwner(primaryStage);
//startPage.toFront();
Scene scene = new Scene(agentsPanel(), 900, 500);
startPage.setScene(scene);
startPage.show();
}
我很感兴趣如何让它拖动可拖动？我希望我将鼠标光标放在它上面以拖动它来改变它的位置.
PS
我测试了这个解决方案,但它不起作用:
private static FlowPane flow;
private static BorderPane bpi;
public static void initStartPage(final Stage primaryStage) {
final Stage startPage = new Stage();
startPage.initStyle(StageStyle.UNDECORATED);
startPage.initOwner(primaryStage);
//startPage.toFront();
Scene scene = new Scene(agentsPanel(primaryStage), 900, 500);
startPage.setScene(scene);
startPage.show();
}

private static double yOffset = 0;

public static void main(String[] args)
{
Application.launch(args);
}
@Override

ImageView imageView = new ImageView();
imageView.setImage(image);

t.setText("Do you want to quit?");

Button btnNo = new Button("No");
btnYes.setStyle("-fx-background-color:\n"

我使用本教程https://tomcat.apache.org/tomcat-7.0-doc/monitoring.html配置了Apache Tomcat 8,并生成了SSL证书.
JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://10.16.70.161:9999/jmxrmi");
HashMap environment = new HashMap();
String[] credentials = new String[]
{
"user", "passw"
};
environment.put(JMXConnector.CREDENTIALS, credentials);
JMXConnector jmxc = JMXConnectorFactory.connect(url, environment);
MBeanServerConnection server = jmxc.getMBeanServerConnection();
Set<ObjectName> s2 = server.queryNames(new ObjectName("Catalina:type=Server,*"), null);
for (ObjectName obj : s2)
{
ObjectName objname = new ObjectName(obj.getCanonicalName());
System.out.println("serverInfo " + server.getAttribute(objname, "serverInfo"));
System.out.println("address " + server.getAttribute(objname, "address"));
System.out.println("stateName " + server.getAttribute(objname, "stateName"));
}
我如何扩展此JMX客户端以将其与SSL证书一起使用？我在互联网上找不到任何好的例子.
我正在尝试为CORS配置Spring以使用Angular Web UI:
我试过这个:
@Configuration
@ComponentScan("org.datalis.admin.config")
public class AppConfig {
@Bean
public static PropertySourcesPlaceholderConfigurer propertyConfigurer() {
PropertySourcesPlaceholderConfigurer conf = new PropertySourcesPlaceholderConfigurer();
conf.setLocation(new ClassPathResource("application.properties"));
return conf;
}
@Bean
public FilterRegistrationBean<CorsFilter> corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
CorsConfiguration config = new CorsConfiguration();
config.setAllowCredentials(true);
config.addAllowedOrigin("127.0.0.1");
config.addAllowedHeader("*");
config.addAllowedMethod("*");
source.registerCorsConfiguration("/**", config);
FilterRegistrationBean<CorsFilter> bean = new FilterRegistrationBean<CorsFilter>(new CorsFilter(source));
bean.setOrder(0);
return bean;
}
}
具有Angular FE的Apache服务器在同一服务器上运行Wildly服务器,因此我为源配置了127.0.0.1.
但我仍然得到:
Access to XMLHttpRequest at 'http://123.123.123.123:8080/api/oauth/token' from origin 'http://123.123.123.123' has been blocked by CORS policy: Response to preflight request doesn't …我有一个非常基本的Spring Job示例。
@Scheduled(fixedRate = 90000)
public void myScheduler() throws Exception {
// Print here execution time into console and save into DB
}
我必须做一些非常繁重的计算。有没有一种方法可以计算总执行时间？侦听器有一个解决方案，但是我想在作业内部执行此操作，因为我想在Job实施代码中执行此操作。
我有一个庞大的Java应用程序。我想拦截所有Java异常并通过电子邮件发送它们。我不能在任何地方添加代码以通过发送代码，try-catch因此是否可以使用例如Aspect将异常拦截为低级类并获取异常内容？
还是有某种方法可以覆盖某些内部Java类并获取异常有效负载？
有什么可能？
我想为MongoDB生成测试数据.大小应为200 Mb.我试过这段代码:
@Test
public void testMongoDBTestDataGenerate()
{
MongoClient mongoClient = new MongoClient("localhost", 27017);
DB db = mongoClient.getDB("development");
DBCollection collection = db.getCollection("ssv");
for (int i = 0; i < 100; i++)
{
BasicDBObject document = new BasicDBObject();
document.put("database", "test");
document.put("table", "hosting");
BasicDBObject documentDetail = new BasicDBObject();
documentDetail.put("records", 99);
documentDetail.put("index", "vps_index1");
documentDetail.put("active", "true");
document.put("detail", documentDetail);
collection.insert(document);
}
mongoClient.close();
}
如何使用此大小精确生成数据？
我将此代码用于REST API请求.

我如何添加连接异常处理程序？我想实现一些自定义逻辑？这个功能易于实现吗？
我迁移到最新springfox-swagger2版本，2.10.0但看起来@EnableSwagger2已被弃用。
为了在 Spring Boot 项目中启用 Swagger，我应该使用什么注释？@EnableSwagger2WebMvc?
