问题 I'm making a light weight painting application with JavaFx. I've been having some issues with my LayerController class and it's methods addLayer etc. So I thought that writing some JUunit test cases would be a good idea to check the correctness of my methods. To make the story short, I'm painting on a Canvas using its GraphicsContext in a selfmade class which I call PaintGraphics . This class does all the painting. The LayerController needs a PaintGraphics to do its work on the layers. But it

问题 Ok, I know this is considered an anti-pattern, and I am certainly open to a better way of doing this. I have a map of enum values. I want to ensure that each of those enum values is assigned to something. My test looks like this. @Test public void eachRowRequiresCellCalc() { Model model = new Model(); EnumValues[] values = EnumValues.values(); for (EnumValues value : values) { Assert.assertTrue(String.format("%s must be assigned", value.name()), model.hasEnumValue(value)); } } This works and

问题 I am facing a common error with Hibernate sessions : javax.persistence.TransactionRequiredException: Executing an update/delete query. I found a solution, make my test class extends AbstractTransactionalJUnit4SpringContextTests but I don't understand why is it necessary. I try to set junit (4.11 version) tests on my project. My test class : _ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath:config/ioc/application-context-spring-test.xml" })

Topic Tree, Depth-first Search Description https://leetcode.com/problems/same-tree/ Given two binary trees, write a function to check if they are the same or not. Two binary trees are considered the same if they are structurally identical and the nodes have the same value. Example 1 : Input: 1 1 / \ / \ 2 3 2 3 [1,2,3], [1,2,3] Output: true Example 2 : Input: 1 1 / \ 2 2 [1,2], [1,null,2] Output: false Example 3 : Input: 1 1 / \ / \ 2 1 1 2 [1,2,1], [1,1,2] Output: false Analysis 方法一：递归前序遍历 方法二：非递归前序遍历 Submission import java.util.Arrays; import java.util.LinkedList; import com.lun.util

maven常用命令

上面是指定端口运行程序的，也可以先指定好，直接在上面的地方写jettty:run 当然，如果你是在控制台运行且安装了maven，直接可以进入项目的文件中：mvn jetty:run 就是说，在控制台运行只要加上一个mvn就ok了 你先需要理解maven的生命周期与插件目标这两个概念。 拿Maven clean来说吧。生命周期为clean.插件目标为maven-clean-plugin:clean。 Maven build是这个插件让你自己去配置执行目标的。 Maven clean 清除上一次Maven执行的结果 Maven generate-sources会根据pom配置去生成 源代码 格式的包 Maven install将项目输出构件部署到本地仓库 maven最主要的作用有两个方面，一个是对jar包的依赖解决功能，自己管理jar包，另一个功能就是项目的构建，打包部署。现在我觉得最重要的还是maven的生命周期和插件机制，下面就来总结一下吧。 mvn install 是将你打好的jar包安装到你的本地库中，一般没有设置过是在 用户目录下的 . m2 \下面。 mvn package 只是将你的代码打包到输出目录，一般的是 target下面。 eclipse插件，m2eclipse 1.maven install相当于maven原生的命令： mvn install 2.aven
