Solving idea debug mode code changes can not take effect

Under IDEA environments devtoolsachieve the thermal load and modify the code to achieve hot deployment need to restart the

1. The introduction of maven dependent devtools

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

2. Also arranged in a fork attribute in a plugin, and configured to true.

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <fork>true</fork>
            </configuration>
        </plugin>
    </plugins>
</build>

3. Set IDEA

Runtime compiler configuration: the key combination: "Shift + Ctrl + Alt + /", select the "Registry", select the tick "compiler.automake.allow.when.app.running".

4. Compile automated configuration:

“File” -> “Settings” -> “Build,Execution,Deplyment” -> “Compiler”，选中打勾 “Build project automatically” 。

5. Configure about application.properties

In some versions we need to configure the switch thermal load into force, its value is equal to true. The following is a format configuration properties, like yml format students can self-adjust
