我有一个基本的 SpringBoot 应用程序。使用 Spring Initializer，嵌入 Tomcat，Thymeleaf 模板引擎，并打包为可执行 JAR 文件。 是一个带有 Spring Boot 的多模块项目，该项目将有 3 个模块。 这里是父模块 pom.xml

我从父根生成所有模块使用:
mvn clean package
但问题是 tdk-web-0.0.2-SNAPSHOT.jar 不包含 tdk-core-0.0.2-SNAPSHOT.jar 和然后它在启动时失败
这里是 Maven 结果:

这是我得到的错误:

Description:
Field emailService in com.tdkcloud.web.controllers.AppErrorController required a bean of type 'com.tdkcloud.backend.service.EmailService' that could not be found.

我解压了jar，里面没有核心模块的类
将建议的代码添加到模块网络:
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<phase>install</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
我有下一个错误:解析模板“/tdk/login/login”时出错，模板可能不存在或可能无法被任何已配置的模板资源访问
但是模板在那里:
最佳答案
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<executable>true</executable>
</configuration>
<executions>

我建议用这个来创建一个可执行的 Jar。

我正在使用Ruby2.1.1和Rails4.1.0.rc1。当执行railsc时，它被锁定了。使用Ctrl-C停止，我得到以下错误日志:~/.rvm/gems/ruby-2.1.1/gems/spring-1.1.2/lib/spring/client/run.rb:47:in`gets':Interruptfrom~/.rvm/gems/ruby-2.1.1/gems/spring-1.1.2/lib/spring/client/run.rb:47:in`verify_server_version'from~/.rvm/gems/ruby-2.1.1/gems/spring-1.1.
最近，当我启动我的Rails服务器时，我收到了一长串警告。虽然它不影响我的应用程序，但我想知道如何解决这些警告。我的估计是imagemagick以某种方式被调用了两次？当我在警告前后检查我的git日志时。我想知道如何解决这个问题。-bcrypt-ruby(3.1.2)-better_errors(1.0.1)+bcrypt(3.1.7)+bcrypt-ruby(3.1.5)-bcrypt(>=3.1.3)+better_errors(1.1.0)bcrypt和imagemagick有关系吗？/Users/rbchris/.rbenv/versions/2.0.0-p247/lib/ru
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
