idea使用spring-boot-devtools

1. 把Build Project Automatically打钩

 

2.  按shift+ctrl+alt+/

 

 

3.  compiler.automake.allow.when.app.running 打钩

 

4. 工程配置

<dependencies>

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

</dependencies>

 

   <build>
        <plugins>

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

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>${java.version}</source>
                    <target>${java.version}</target>
                </configuration>
            </plugin>


        </plugins>

    </build>

 

如果没效果，重启下idea
