SpringBoot devtools 的远程应用 这句话什么意思？
Spring Boot开发者工具并不仅限于本地开发，在运行远程应用时你也可以使用一些特性。
远程支持是可选的，你需要确保开发者工具被包含在重新打包的归档文件中。
即对于本地代码的修改，能够实时的更新到远程应用中，从而实现本地代码和远程应用的联合调试。
1. 将devtools打到jar包中
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<excludeDevtools>false</excludeDevtools>
</configuration>
</plugin>
</plugins>
</build>
2. 设置spring.devtools.remote.secret属性
在application.properties中配置
spring.devtools.remote.secret=mysecrt
或在application.yml中配置
spring:
devtools:
remote:
secret: mysecret
3. 打好jar包，并在远程服务器运行

4. 创建并启动客户端程序
【Run】-> 【Edit Configuration】-> 点击加号 -> 选择 Application，如下图填写 ，最后OK。

最后运行它。
运行结果如下：

5. 修改本地项目代码，编译项目。
未修改HelloController之前
@Controller
public class HelloController {
@RequestMapping("/hello")
public String hello() {
System.out.println("Hello!");
return "hello";
}
}
访问 http://192.168.0.152:8090/hello，控制台输出：
...
2019-01-15 19:03:51.096 INFO 19286 --- [nio-8090-exec-1] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring DispatcherServlet 'dispatcherServlet'
2019-01-15 19:03:51.096 INFO 19286 --- [nio-8090-exec-1] o.s.web.servlet.DispatcherServlet : Initializing Servlet 'dispatcherServlet'
2019-01-15 19:03:51.104 INFO 19286 --- [nio-8090-exec-1] o.s.web.servlet.DispatcherServlet : Completed initialization in 8 ms
Hello!
修改HelloController
@Controller
public class HelloController {
@RequestMapping("/hello")
public String hello() {
System.out.println("Hello World !");
return "hello";
}
}
然后重新编译，在IDEA中【Build Project】。
客户端程序控制台会输出

这个过程是不是就像在本地热部署一样啊！！
