NB :当版本更改为 1.4.2.RELEASE 时，它可以正常工作，并且不会引发上述异常

NB: when the version is changed to 1.4.2.RELEASE, it works fine and didn't throw the above exception

推荐答案

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

Problem exist due to version of artifact. Remove the version in org.springframework.boot spring-boot-devtools in pom.xml.

内部pom.xml

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

内部build.gradle文件

Inside build.gradle file

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