how to make auto reload with Spring-boot on IDEA Intellij

Question

I had wrote a project base on Spring-boot,tomcat,freemarker, I run it successful, but whenever I modify some templates and java class, I must restart server or use "reload changed classes" menu on Intellij to make the changes become effective. It wastes lots time!

Then I try to use springloaded as the official said :

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>springloaded</artifactId>
            <version>1.2.0.RELEASE</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/lib/springloaded-1.2.0.RELEASE.jar</systemPath>
        </dependency>
    </dependencies>
</plugin>

then I rerun server, but doesn't work as expected! I still need to restart server after any change on template or class.

How could I configure the springloaded to auto reload. Thanks a lot!

The version of Spring-boot is 1.3.0RC1

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.0.RC1</version>
</parent>

maven version:3.2 jdk:1.8 intellij :14.1.5 os:windows 8.1 64 bit

Answer 1

First, be sure that you added spring-boot-devtools as dependency:

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

Second, verify that the option check-box File->Setting –> Build, Execution, Deployment –> Compiler–> Build project automatically is selected.

Last, press SHIFT+CTRL+A for Linux/Windows users or Command+SHIFT+A for Mac users, then type registry in the opened pop-up window. Scroll down to Registry... using the down arrow key and hit ENTER on Registry... . In the Registry window verify the option compiler.automake.allow.when.app.running is checked.

If the static files are not reloaded, press CTRL+F9 to force a reload.

The instructions above are taken from here

Answer 2

For macOS

1. Preference -> Compiler -> check BUild project on build automatically

2. shift + command + A

check compiler.automake.allow.when.app.running

If the static files are not reloaded, press CTRL+F9 to force a reload.

Answer 3

CTRL+F9 to make project with debugging. The idea is to make the project automatically work while not running or debugging!

Setting->Build->Compiler->check Make project automatically.

Answer 4

Note::For who those not found that option in registry.The newer version of intellij idea for my case @Version:2021.2 the compiler.automake.allow.when.app.running option is moved to advanced settings:

Answer 5

Possibly you could check if build is fired on any changes on Build Tools settings
