SpringBoot（二）：SpringBoot 热部署

每次修改代码都要重启服务器的痛，别说你不懂。

一、环境

IntelliJ IDEA 2017.1.4 x64

二、SpringBoot 配置

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

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

三、IDEA 设置

自动build



Register配置

Ctrl+Shift+Alt+/ => Register => 找到并勾选compiler.automake.allow.when.app.running => IDEA重启

四、测试

确认IDEA重启后，debug启动SpringBoot项目，修改第一篇文章的HelloController

@RequestMapping(value = "sayhello", method = RequestMethod.GET)
public String sayhello(){
return "Hello SpringBoot !";
}

"Hello SpringBoot !"; == > "Hello SpringBoot 2 !";



测试成功
