我使用一个小型 Spring Boot 项目,在使用命令 mvn clean install 时出现以下错误

如何解决问题?
最佳答案
您为依赖项设置的范围是测试。因此在使用 clean install 时不包含它。删除范围标记并重试。

我真的很习惯使用Ruby编写以下代码:my_hash={}my_hash['test']=1Java中对应的数据结构是什么? 最佳答案 HashMapmap=newHashMap();map.put("test",1);我假设? 关于java-等价于Java中的RubyHash,我们在StackOverflow上找到一个类似的问题: https://stackoverflow.com/questions/22737685/
我正在尝试使用boilerpipe来自JRuby。我看过guide从JRuby调用Java,并成功地将它与另一个Java包一起使用,但无法弄清楚为什么同样的东西不能用于boilerpipe。我正在尝试基本上从JRuby中执行与此Java等效的操作:URLurl=newURL("http://www.example.com/some-location/index.html");Stringtext=ArticleExtractor.INSTANCE.getText(url);在JRuby中试过这个:require'java'url=java.net.URL.new("http://www

这篇文章是继上一篇文章“Observability:从零开始创建Java微服务并监控它(一)”的续篇。在上一篇文章中,我们讲述了如何创建一个Javaweb应用,并使用Filebeat来收集应用所生成的日志。在今天的文章中,我来详述如何收集应用的指标,使用APM来监控应用并监督web服务的在线情况。源码可以在地址 https://github.com/liu-xiao-guo/java_observability 进行下载。摄入指标指标被视为可以随时更改的时间点值。当前请求的数量可以改变任何毫秒。你可能有1000个请求的峰值,然后一切都回到一个请求。这也意味着这些指标可能不准确,你还想提取最小/
HashMap中为什么引入红黑树,而不是AVL树呢1.概述开始学习这个知识点之前我们需要知道,在JDK1.8以及之前,针对HashMap有什么不同。JDK1.7的时候,HashMap的底层实现是数组+链表JDK1.8的时候,HashMap的底层实现是数组+链表+红黑树我们要思考一个问题,为什么要从链表转为红黑树呢。首先先让我们了解下链表有什么不好???2.链表上述的截图其实就是链表的结构,我们来看下链表的增删改查的时间复杂度增:因为链表不是线性结构,所以每次添加的时候,只需要移动一个节点,所以可以理解为复杂度是N(1)删:算法时间复杂度跟增保持一致查:既然是非线性结构,所以查询某一个节点的时候
遍历文件夹我们通常是使用递归进行操作,这种方式比较简单,也比较容易理解。本文为大家介绍另一种不使用递归的方式,由于没有使用递归,只用到了循环和集合,所以效率更高一些!一、使用递归遍历文件夹整体思路1、使用File封装初始目录,2、打印这个目录3、获取这个目录下所有的子文件和子目录的数组。4、遍历这个数组,取出每个File对象4-1、如果File是否是一个文件,打印4-2、否则就是一个目录,递归调用代码实现publicclassSearchFile{publicstaticvoidmain(String[]args){//初始目录Filedir=newFile("d:/Dev");Datebeg
我基本上来自Java背景并且努力理解Ruby中的模运算。(5%3)(-5%3)(5%-3)(-5%-3)Java中的上述操作产生,2个-22个-2但在Ruby中,相同的表达式会产生21个-1-2.Ruby在逻辑上有多擅长这个?模块操作在Ruby中是如何实现的?如果将同一个操作定义为一个web服务,两个服务如何匹配逻辑。 最佳答案 在Java中,模运算的结果与被除数的符号相同。在Ruby中,它与除数的符号相同。remainder()在Ruby中与被除数的符号相同。您可能还想引用modulooperation.
Java的Collections.unmodifiableList和Collections.unmodifiableMap在Ruby标准API中是否有等价物? 最佳答案 使用freeze应用程序接口(interface):Preventsfurthermodificationstoobj.ARuntimeErrorwillberaisedifmodificationisattempted.Thereisnowaytounfreezeafrozenobject.SeealsoObject#frozen?.Thismethodretur
