org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/json;charset=UTF-8' not supported或其他Content type不支持處理

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

 

排查思路

 

1.是否在異步請求有如下設置

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

 

2.是否導入jackson坐標

<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.版本沖突(嘗試更換fackson等版本)
