通常我們?cè)趯憇printgboot程序時(shí)，為了防止重復(fù)啟動(dòng)應(yīng)用程序，都會(huì)加入熱啟動(dòng)的相關(guān)配置。通常默認(rèn)的配置對(duì)于我們大多數(shù)開發(fā)已經(jīng)否用了。引入依賴如下：

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-devtools</artifactId>
      <version>1.5.8.RELEASE</version>
      <optional>true</optional>
</dependency>

但是，當(dāng)我們?cè)谧錾蟼魑募奖镜胤?wù)器，比如classpath目錄后，由于devtools檢測(cè)到classpath目錄的文件發(fā)生了改變，便會(huì)自動(dòng)重啟，而此時(shí)的重啟并不是我們需要的。所以我們便需要做如下配置，其目的是額外排除需要重啟的目錄，如下：static目錄下的所有子目錄和文件將被devtools額外排除。

spring:
  devtools:
    livereload:
      enabled: true
    restart:
      additional-exclude: static/**

上傳文件到本地服務(wù)器的接口一般采用POST接口，上傳一個(gè)或者多個(gè)文件到本地服務(wù)器上的某個(gè)指定目錄，并更改文件名。
