Intellij IDEA – Auto reload a web application

Question

I'm developing an AngularJS and Spring boot application using IntelliJ IDEA 15 and tomcat, whenever I make changes to my static content I've always to restart my application to see those changes.

I looked for a similar problem and I have found this :

Enable IntelliJ hotswap of html and javascript files

But I cant find Update resources option anywhere :

Edit :

This is my project structure :

And this is my pom file :

Answer 1

In Spring Boot application if you include spring-boot-devtools module as one of your dependency, it can give you additional feature like automatically restart the application whenever files change on classpath.

Add the following dependencies

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <optional>true</optional>
    </dependency>
</dependencies>

if using Gradle

dependencies {
    compile("org.springframework.boot:spring-boot-devtools")
}

Since you are using IntelliJ to trigger automatic restart you need to Make Project ( Build -> Make Project ) (Ctrl + F9 on Windows)
