当两个依赖同时存在时,或者只引入spring-boot-starter-web,程序运行正常
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>2.5.2</version>
    </dependency>
    <dependency>
        <groupId>org.openjdk.jol</groupId>
        <artifactId>jol-core</artifactId>
        <version>0.16</version>
    </dependency>
</dependencies>
 
当剔除jol-core依赖时,报错如下;
java: 程序包org.springframework.beans.factory.annotation不存在
 
解决方法:重新引入spring-boot-starter-web依赖即可
