原因
导入之后缺少spring-boot-starter-json依赖

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>2.11.3</version>
        </dependency>

解决方法
去https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-json/2.3.3.RELEASE
网站下一个

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-json -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-json</artifactId>
    <version>2.3.3.RELEASE</version>
</dependency>

注意修改jdk版本，maven重新引入之后会改变jdk版本
