小编La *_*ell的帖子

我有一个基于Spring Web模型 - 视图 - 控制器(Spring MVC 3.2.8)的应用程序,我想使用FTP SessionFactory的默认实现与FTP集成.

我有这段代码

private void performImport() throws Exception {

    String fileNamePattern="*.txt";

    ftpInboundFileSynchronizer = new FtpInboundFileSynchronizer(myFtpSessionFactory );
            ((FtpInboundFileSynchronizer) ftpInboundFileSynchronizer).setFilter(new FtpSimplePatternFileListFilter(fileNamePattern));

    ftpInboundFileSynchronizer.setRemoteDirectory(remoteDirectory);

    deleteLocalFiles();

    System.out.println ("before synchronize");

    ftpInboundFileSynchronizer.synchronizeToLocalDirectory(localDirectory);

    System.out.println ("after synchronize");
}

这是我在控制台中看到的:

before synchronize
after synchronize

在FTP我有一个test.txt文件,但文件没有传输,我没有错误/异常

我也尝试过使用fileNamePattern="*.*";但它也不起作用

这是我的配置文件:

@Configuration
@PropertySource("classpath:/config/application.properties")
public class FtpConfiguration {

    @Autowired
    private SessionFactory myFtpSessionFactory;

    @Bean
    @Scope(value="step")
    public FtpGetRemoteFilesTasklet myFtpGetRemoteFilesTasklet()
    {
        FtpGetRemoteFilesTasklet  ftpTasklet = new FtpGetRemoteFilesTasklet();
        ftpTasklet.setRetryIfNotFound(true);
        ftpTasklet.setDownloadFileAttempts(3);
        ftpTasklet.setRetryIntervalMilliseconds(10000);
        ftpTasklet.setFileNamePattern("README");
        //ftpTasklet.setFileNamePattern("TestFile");
        ftpTasklet.setRemoteDirectory("/");
        ftpTasklet.setLocalDirectory(new File(System.getProperty("java.io.tmpdir")));
        ftpTasklet.setSessionFactory(myFtpSessionFactory);

        return ftpTasklet; …

我有一个以字符串格式ddMMyyyy和hh:mm以及TimeZone存储在DB中的日期.我想根据这些信息创建一个Instant,但我不知道该怎么做.

就像是

LocalDateTime dateTime = LocalDateTime.of(2017, Month.JUNE, 1, 13, 39);
Instant instant = dateTime.toInstant(TimeZone.getTimeZone("ECT"));

我想逆向工程我的工作区的注册包,所以我去模型浏览器,点击鼠标右键,我应该看到一个带有选项导入的菜单,菜单选项:

• 导入注册档案
• 导入注册包
• 从用户模型导入包

但这就是我所看到的:

这是纸莎草纸的版本

我还试图将包从包浏览器中反向设计的包拖放到类图中,但它没有用完..

我有一个SpringBoot应用程序.使用Spring Initializer,嵌入式Tomcat,Thymeleaf模板引擎和包作为可执行的JAR文件.

我有一个具有2个属性的域对象(initDate,endDate).我想创建2个转换器来处理mySQL DB

@Convert(converter = LocalDateTimeAttributeConverter.class) 
private LocalDateTime initDate;

@Convert(converter = ZonedDateTimeAttributeConverter.class) 
private ZonedDateTime endDate;

转换器1(可以)

@Converter
public class LocalDateTimeAttributeConverter implements AttributeConverter<LocalDateTime, Timestamp> {

    @Override
    public Timestamp convertToDatabaseColumn(LocalDateTime localDateTime) {
        return (localDateTime == null ? null : Timestamp.valueOf(localDateTime));
    }

    @Override
    public LocalDateTime convertToEntityAttribute(Timestamp sqlTimestamp) {
        return (sqlTimestamp == null ? null : sqlTimestamp.toLocalDateTime());
    }
}

这是我想要创建的那个

@Converter
public class ZonedDateTimeAttributeConverter implements AttributeConverter<ZonedDateTime, Timestamp> {

    @Override
    public Timestamp convertToDatabaseColumn(ZonedDateTime zoneDateTime) {
        return (zoneDateTime == null ? null : Timestamp.valueOf(zoneDateTime));
    } …

我有这几个函数,我想知道是否可以将参数传递deviceEvent.hasAlarm()给.map(this::sendSMS)

private void processAlarm (DeviceEvent deviceEvent)  {

        notificationsWithGuardians.stream()
                    .filter (notification -> notification.getLevels().contains(deviceEvent.getDeviceMessage().getLevel()))
                    .map(this::sendSMS)
                    .map(this::sendEmail);

    }

    private DeviceAlarmNotification sendSMS (DeviceAlarmNotification notification, DeviceEvent deviceEvent)  {

        if (deviceEvent.hasAlarm()) {       

        }

        return notification;

    }

我在DB中存储了这个时间框架:伦敦(BST)的15:00到16:00的任何一天

当我在此时间帧之间收到事件时,我需要执行一个程序IF.

我现在在巴黎(16:22)运行测试,在伦敦是15:22(因此在存储在数据库中的时间帧之间).

这是我的代码

// create Local Date Time from what I have stored in the DB

LocalDateTime dateTime1 = LocalDateTime.of(2017, Month.JUNE, 15, 15, 00);
LocalDateTime dateTime2 = LocalDateTime.of(2017, Month.JUNE, 15, 16, 00);

Instant now = Instant.now();

System.out.println (now.isAfter (dateTime1.atZone(ZoneId.of("BST", ZoneId.SHORT_IDS)).toInstant()));
System.out.println (now.isBefore(dateTime2.atZone(ZoneId.of("BST", ZoneId.SHORT_IDS)).toInstant()));

理论上现在(在巴黎16:22 /伦敦15:22)是在伦敦(15:00)的dateTime1之后和伦敦的dateTime2(16:00)之前

但我现在不是那个dateTime2之前的那个

是否可以在 th:text 中包含 Html 标签？

例如：

<h2 th:text="'LOCATION INFO Device &lt;strong&gt;' + ${deviceKey} + ' &lt;/strong&gt;  at ' + ${deviceEventTime} ">

我想将Weblogic库放入本地存储库(安装和配置Maven以进行构建自动化和依赖管理)我在我的工作站中安装了Weblogic版本12.1.2.

我运行这个命令:

mvn -X com.oracle.maven:oracle-maven-sync:push -Doracle-maven-sync.oracleHome=C:\Oracle\product\11.2.0\client_x86 -Doracle-maven-sync.testingOnly=false

但是我收到了这个错误:

我现在正在巴黎运行这段代码,其中12:40,其中ECT = ECT - 欧洲/巴黎

LocalDateTime creationDateTime = LocalDateTime.now(Clock.systemUTC());      
ZoneId zone = ZoneId.of(ZoneId.SHORT_IDS.get("ECT"));


System.out.println ("creationDateTime --------------------------> " + creationDateTime);        
System.out.println ("creationDateTime.atZone(zone).getHour() ---> " + creationDateTime.atZone(zone).getHour());
System.out.println ("creationDateTime.atZone(zone).getMinute() -> " + creationDateTime.atZone(zone).getMinute());

但我在控制台得到这个

creationDateTime --------------------------> 2017-05-16T10:40:07.882
creationDateTime.atZone(zone).getHour() ---> 10
creationDateTime.atZone(zone).getMinute() -> 40

我不应该得到12:40 ???????

据我所知,构造函数注入强制执行强制依赖,而setter注入允许可选的依赖,但是...

那么这种做法是不可能的???

@Component
public class Car {

    @Autowired(required=false)
    public Car(Engine engine, Transmission transmission) {
        this.engine = engine;
        this.transmission = transmission;
    }
}
