Spring显示Content type 'application/json;charset=UTF-8' not supported

排查思路

1.是否在异步请求有如下设置

contentType:"application/json;charset=utf-8"

2.是否导入jackson坐标

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.12.2</version>
</dependency>

3.是否在Spring的配置文件中配置

<mvc:annotation-driven/>

4.版本冲突(尝试更换fackson等版本)
