注意：当版本更改为1.4.2.RELEASE时，它可以正常工作，并且没有引发上述异常

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

For Maven inside pom.xml
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
    </dependency>
<dependencies>

For Gradle inside build.gradle file
dependencies {
    compile "org.springframework.boot:spring-boot-devtools" 
}
