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

which spring-boot version are you using? If i remember correctly the reload of java classes is possible since 1.3.0 (only RC1 available right now). But I'm not sure about this. You may verify this — Yannic Bürgmann, Oct 26 '15 at 15:31
Maybe somehow unrelated, but autoreloading works out of the box in netbeans. — ACV, Sep 14 '18 at 09:24

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

For macOS

Preference -> Compiler -> check "Build project automatically"
shift + command + A

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

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

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.

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