How to run Spring Boot web application in Eclipse itself?
提问by Krishan Babbar
I am able to run few sample applications in my Eclipse (STS). Now, I want to run a web application within eclipse itself.
我能够在我的 Eclipse (STS) 中运行几个示例应用程序。现在，我想在 eclipse 本身中运行一个 Web 应用程序。
I tried with sample application "spring-boot-sample-web-jsp" given at the linkand I am able to export its war into external tomcat and run the application. Now my question is how to run a Spring Boot Web application into eclipse itself?
我试图在给定的样本应用程序“春天引导样本的web-JSP”链接，我能够将其War导出到外部Tomcat和运行应用程序。现在我的问题是如何将 Spring Boot Web 应用程序运行到 eclipse 本身中？
回答by geoand
Just run the mainmethod which is in the class SampleWebJspApplication.
Spring Boot will take care of all the rest (starting the embedded tomcat which will host your sample application).
只需运行类中的main方法SampleWebJspApplication。Spring Boot 将负责所有其余的工作（启动将托管您的示例应用程序的嵌入式 tomcat）。

This answer is late, but I was having the same issue. I found something that works.
In eclipse Project Explorer, right click the project name -> select "Run As" -> "Maven Build..."
In the goals, enter spring-boot:runthen click Run button.
这个答案很晚，但我遇到了同样的问题。我发现了一些有效的东西。
在 eclipse Project Explorer 中，右键单击项目名称 -> 选择“Run As” -> “Maven Build...”
在目标中，输入spring-boot:run然后单击 Run 按钮。
I have the STS plug-in (i.e. SpringSource Tool Suite), so on some projects I will get a "Spring Boot App" option under Run As. But, it doesn't always show up for some reason. I use the above workaround for those.
Here is a reference that explains how to run Spring boot apps:
Spring boot tutorial
我有STS插件（即SpringSource Tool Suite），所以在一些项目中我会在Run As下得到一个“Spring Boot App”选项。但是，由于某种原因，它并不总是出现。我使用上述解决方法。
这是解释如何运行 Spring boot 应用程序的参考：

You can also use the "Spring Boot App" run configuration. For that you'll need to install the Spring Tool Suite plug-in for Eclipse.
您还可以使用“Spring Boot App”运行配置。为此，您需要为 Eclipse安装Spring Tool Suite 插件。

In my case, I had to select the "src/main/java" and select the "Run As" menu Just like this, so that "Spring Boot App" would be displayed as here.
在我的情况下，我必须选择“src/main/java”并选择“Run As”菜单 就像这样，这样“Spring Boot App”就会显示为here。

I was also trying to run Spring Boot application in Eclipse, without any plugins.
我还尝试在 Eclipse 中运行 Spring Boot 应用程序，没有任何插件。
Step 1
第1步
Right click on your project. Select "Run As" -> "Maven build...". Then in "Goals" field, enter "spring-boot:run". Apply & Run.
右键单击您的项目。选择“运行方式”->“Maven 构建...”。然后在“目标”字段中，输入“spring-boot:run”。应用和运行。
After this you do not have to Run again.
在此之后，您不必再次运行。
Step 2
第2步
After making any change, clean your project. After cleaning, it automatically builds the project once. Then when you will refresh your pages on browser, change will be reflected.
进行任何更改后，请清理您的项目。清理后，它会自动构建项目一次。然后当您在浏览器上刷新页面时，更改将被反映。
回答by Prabhakar Kumar Ojha
If you are doing code in STS you just need to add the devtools dependency in your maven file. After that it will run itself whenever you will do some change.
如果你在 STS 中做代码，你只需要在你的 maven 文件中添加 devtools 依赖项。之后，只要您进行一些更改，它就会自行运行。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
</dependency>
