Springboot實現devtools熱部署

1.添加pom依賴

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

2.修改配置

• windows版：File-Settings-Compiler-Build-勾選Project automatically
• mac版idea:IntellIJ IDEA-Preference-File-Settings-Compiler-勾選Build Project automatically
• windows版idea:ctrl+shift+alt+/,選擇Registry,勾選Compiler automake allow when app running
• mac版idea:option+command+shift+/,選擇Registry,勾選Compiler automake allow when app running

3.編譯重啓

• windows版：ctrl+F9如果有改動編譯重啓（Build-Build Project）
• mac版：fn+command+F9如果有改動就編譯重啓（Build-Build Project）

4.官方文檔說明

Triggering a restart

As DevTools monitors classpath resources, the only way to trigger a restart is to update the classpath. The way in which you cause the classpath to be updated depends on the IDE that you are using. In Eclipse, saving a modified file causes the classpath to be updated and triggers a restart. In IntelliJ IDEA, building the project (Build -> Build Project) has the same effect.
