在gradle build我的Web应用程序的根目录中运行后,声明的spring安全性依赖项build.gradle不会被下载.

这是我的 build.gradle

我想基于现有的Eclipse安装创建一个Oomph产品安装文件.有没有办法生成安装文件作为当前安装的一种快照？

我有一个包含两列(纬度,经度)的csv文件,其中包含超过500万行的地理位置数据.我需要识别与列表中任何其他点不在5英里范围内的点,并将所有内容输出回另一个具有额外列的CSV(CloseToAnotherPoint),True如果有另一个点在5英里内,并且False如果有"T.

这是我当前使用的解决方案geopy(不进行任何Web调用,只使用函数来计算距离):

from geopy.point import Point
from geopy.distance import vincenty
import csv


class CustomGeoPoint(object):
    def __init__(self, latitude, longitude):
        self.location = Point(latitude, longitude)
        self.close_to_another_point = False


try:
    output = open('output.csv','w')
    writer = csv.writer(output, delimiter = ',', quoting=csv.QUOTE_ALL)
    writer.writerow(['Latitude', 'Longitude', 'CloseToAnotherPoint'])

    # 5 miles
    close_limit = 5
    geo_points = []

    with open('geo_input.csv', newline='') as geo_csv:
        reader = csv.reader(geo_csv)
        next(reader, None) # skip the headers
        for row in reader:
            geo_points.append(CustomGeoPoint(row[0], row[1]))

    # for every point, …

我想创建一个自定义Eclipse,它具有Mybatipse以及默认安装的其他一些插件.我正在使用Eclipse中的Oomph产品设置来创建我的产品.我的猜测是在P2 director节点中添加一个要求,但我不知道如何正确设置它.我已经看过将插件的名称放在需求的名称部分中的示例,org.eclipse.emf.compare.source.feature.group但我不知道从哪里获取我想要的插件的信息.我甚至走向了正确的方向吗？

在调试模式下启动应用程序时,它询问我是否要打开调试透视图.我检查了我的决定,但必须不小心点击'是'而不是'否'.我该怎么撤消这个？

我正在尝试获取下一个即将到来的星期五的日期，并将其格式设置为yyyyMMDD。如果可能，我想不使用JodaTime来执行此操作。这是我的代码：

import java.time.LocalDate;
import java.time.temporal.TemporalAdjusters;
import java.time.DayOfWeek;
import java.time.format.DateTimeFormatter;

// snippet from main method
LocalDate friday = LocalDate.now().with(TemporalAdjusters.next(DayOfWeek.FRIDAY));
DateTimeFormatter formatter = DateTimeFormatter.ofPattern('yyyyMMDD');
System.out.println(friday.format(formatter));

但是当我运行此命令时，出现以下错误（今天运行20170809）

java.time.DateTimeException: Field DayOfYear cannot be printed as the value 223 exceeds the maximum print width of 2

我究竟做错了什么？

编辑：我正在使用Java 8

在我对UserDetailsS​​ervice的自定义实现使用Bcrypt之前,我首先想看看我是否可以在内存数据库中使用它.

我正在做一个计划项目，该项目定期执行多个作业。我正在使用cron调度，如下例所示。作业已成功执行，没有问题。但是，出于需求，我想计算并保留DB中计划作业的下一次运行时间。对于以下配置，是否有解决方案来获取作业的上一次和下一次启动时间？

配置示例：

import java.util.Date;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.scheduling.support.CronTrigger;
import org.springframework.stereotype.Component;

@Component
@EnableScheduling
public class DemoServiceBasicUsageCron
{   
    @Scheduled(cron="1,3,30,32 * * * * ?")
    public void demoServiceMethod()
    {
        System.out.println("Curent date time is - "+ new Date());
    }

}

在spring mvc应用程序中配置spring安全性后，运行它时出现以下错误：

我调试,旨在妥善处理的情况下,一个应用程序foo是null.然而,当从生产中检查日志时,NullPointerException尝试访问foo应该正常处理的方法后抛出了一个.

它看起来像这样

if (foo == null) {
    throw new GracefulException();
}

Bar bar = foo.getBar();

因此,使用该代码NullPointerException时,调用时会在生产中发生foo.getBar().

我的问题很简单:有没有人听说过这样的时髦行为,甚至可能发生？如果是这样,可能导致什么呢？

该文档的org.springframework.restdocs.RestDocumentation,它已被弃用状态.

我试图在这样的JUnit测试中使用该类:

@Rule
public RestDocumentation restDocumentation = new RestDocumentation("target/generated-snippets");

我应该使用什么课？

我在Eclipse Oxygen中使用Dark主题.当我将鼠标悬停在类上以查看Javadoc时,链接为蓝色且很难看到

我已经尝试编辑超链接颜色Preferences -> General -> Appearance -> Colors and Fonts -> Basic -> Hyperlink text color但是没有用.根据该Java节Colors and Fonts还有编辑条目Javadoc background和Javadoc text color,但我什么也看不到了的Javadoc超级链接颜色或类似的东西.我可以改变背景颜色作为一种解决方法,但这打破了黑暗的主题,我宁愿不.

I am trying to hook into the creation of the context using a custom application listener like this

@Component
public class ContextStartedListener implements ApplicationListener<ContextStartedEvent> {

    @Override
    public void onApplicationEvent(ContextStartedEvent event) {
        System.out.println("Context started"); // this never happens
    }
}

But the onApplicationEvent method never fires. If I use a different event such as ContextRefreshedEvent then it works just fine, but I need to hook into before it is created. Any advice? Thanks!
