解决

多次百度无果，只能细看报错。发现最后一行：

at org.springframework.boot.devtools.restart.RestartLauncher.run(RestartLauncher.java:49)

怀疑是devtools的问题，然后将pom.xml中的devtools依赖去掉

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
    <scope>runtime</scope>
    <optional>true</optional>
</dependency>
