Java面试——Spring Boot

阅读更多关于 Java面试——Spring Boot

一、谈谈你对 SpringBoot 的理解简单说说我的理解：Java是一个静态语言，相比动态语言，它相对笨重，体现在我们搭建 SSM 框架写一个 helloword 的时候相当复杂，需要写一大堆的配置。还有在导入 jar包依赖的时候版本号问题，令人头疼。但是，我们有 Spring呀，真的是 Java 开发人员的福音。SpringBoot 就是为解决这些问题而生的。让我们写一个 helloword 跟动态语言一样简单。版本控制也通过 springboot与maven的插件进行整合管理，让我们将经历重点放在业务的开发之上。下面我们就说说其优点：【1】创建独立的 Spring 应用，可以通过 java -jar xx.jar 直接运行；【2】直接嵌入 Tomcat、Jetty或Undertow 等 Web 容器（不需要部署 war 文件），后期与云计算平台集成方便（docket）；【3】提供固化的 “starter” 的 pom 配置简化构建 maven 配置，避免大量的Maven导入和各种版本冲突；【4】当条件满足时自动装配 Spring 或第三方类库；【5】提供运维特性，基于 ssh、http、telnet 对服务器进行监控、健康检查以及外部化配置；【6】SpringBoot 不需要 XML 配置，也不是通过代码生成来实现，而是通过条件注解+类实现配置文件；【7

问题 The title is pretty self-explanatory: does anyone know of a (good) properties file reader library for C or, if not, C++?

问题 What is the difference between willSet - didSet , and get - set , when working with this inside a property? From my point of view, both of them can set a value for a property.

I know that for willSet and didSet , the structure looks like this: var variable1 : Int = 0 { didSet { println (variable1) } willSet(newValue) { .. } } var variable2: Int { get { return variable2 } set (newValue){ } } 回答1: When and why should I use

问题 Trying to remove or place items on a property grid by changing the Browsable attribute. But unless browsable is set on object creation my code to change Browsable doesn't work.

Here is my code in the OK button event of MaxScore: private void okBtn_Click(object sender, EventArgs e) { Form1.myGameCountLbl.Text = Form1.max.ToString(); Form1.compGameCountLbl.Text = Form1.max.ToString(); }

问题 I am using a properties file to store my application's configuration values. In one of the instances, I have to store a value as xxx:yyy:zzz . When I do that, the colon is escaped with a back slash \ resulting in the value showing as xxx\:yyy\:zzz in the properties file. I am aware that the colon : is a standard delimiter of the Properties Java class. However I still need to save the value without the back slash \ . Any suggestions on how to handle this? 回答1: Put the properties into the

问题 I am creating a wrapper class in .NET (VB.NET as it happens but is equally related to C#) that is exposed to COM and one of the properties I am trying to wrap is a Variant. I thought I would just be able to use an Object, but I get an error: Public Property FieldValue([vFieldID As Object = -1]) As Object cannot be exposed to COM as a property 'Let'. You will not be able to assign non-object values (such as numbers or strings) to this property from Visual Basic 6.0 using a 'Let' statement.* My
