由于工件的版本存在问题。去掉pom.xml中org.springframework.boot spring-boot-devtools中的版本

行家

在 pom.xml 中

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

Gradle

在 build.gradle 文件中

dependencies {
    compile "org.springframework.boot:spring-boot-devtools" 
}
