The answer to the online search is:

As a result of guava compatibility problems, the introduction

<dependency>    <groupId>com.google.guava</groupId>    <artifactId>guava</artifactId>    <version>20.0</version></dependency>

I opened my MAVEN project to expand Maven dependencies to see the next Jar Package version by keyboard G, and found that the version 16,guava-16.0.1.jar,16 version is incompatible

Then search in the startup subproject Pom.xml file to add

<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>20.0</version>
</dependency>

According to the priority principle, the version will become version 20.
