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)
