Spring is a popular Java application framework.
Spring Boot is an effort to create stand-alone, production-grade Spring based applications with minimal effort. Spring Boot automatically adds static web resources located within any of the following directories:. In our application, we have one HTML file which contains a simple link. The link triggers a response from the web Boot application.
It returns a plain text message. This is the Maven build file. The spring-boot-starter-web is starter for building web applications using Spring MVC. The spring-boot-starter-test imports necessary testing modules.
The application is packaged into a JAR file. We inject a value from the application. The application. We define a custom property having a text message. This is the controller class for the Spring Boot web application.
A controller is decorated with the Controller annotation. The message method responds to a GET request. The ResponseBody annotation puts the string value to the web response body. In the index. In the link tag we refer to the main. In the MyControllerTest we have two tests: one for the home page and one for the returned message text. The Application sets up the Spring Boot application.

BTW: If you start the application in Eclipse with the Spring Plugin, the result depends on your eclipse environment for some developers it works, for some not - guess it depends, which loader is used by eclipse. The change that has stopped this from working is intentional as it aligns Spring Boot more closely with the Servlet spec.
This isn't an option with a jar. I'm going to close this in favour of which will make resource handling consistent across all three containers.
On second thoughts, this would be better handled as a separate issue rather than rolling it into This is also the case for JSP pages. GyllingSW That sample is fine. It is building a war file. If you're doing that then there's no problem. I'm going to close this. There's been relatively little demand for it yet implementing it would add complexity to achieve something that can already been done using one of the two options that I described in my comment above.

Well, same feature can be utilized in spring boot applications using spring-boot-devtools dependency provided features. To enable dev tools in spring boot application is very easy. Just add the spring-boot-devtools dependency in your build file. This is very good feature in production where every milli-second performance improvement matters.
But in development environment, it can be a problem and cause stale cache problem and you may not see your changes immediatly in browser.

To do so, use the spring. Similarily, If you want to keep those defaults and add additional exclusionsuse the spring. Auto-restart means reloading the java classes and consiguration at server side. After the server side changes are re-deployed dynamically, server restart happen and load the modified code and configutation.
By default, each time your application restarts, a report showing the condition evaluation delta is logged. To disable the restart of server on non-static code changes, use the property spring. Automatic restarts may not be desirable on every file change and sometimes can slower down development time due to frequent restarts.
To solve this problem, you can use a trigger file. Spring boot will keep monitoring that file and once it will detect any modification in that file, it will restart the server and reload all your previous changes. Use spring. It can be any external or internal file. Setting all your favorite configutation options everytime for all your spring boot projects or modules may become a duplicate effort. You can minimize it using a global setting file.
Please note that file name start with a dot. Not use this global property file to configure globally available options. Reference: Spring boot Ref. A family guy with fun loving nature.
