SpringMVC中前端发送post请求一直提示415

Question

这是配置类

@Configuration
@ComponentScan("SpringMVC.Controller")
@EnableWebMvc
public class MvcConfig{
    @Bean
    public HandlerAdapter handlerAdapter() {
        return new RequestMappingHandlerAdapter();
    }
    @Bean
    public HandlerMapping handlerMapping() {
        return new RequestMappingHandlerMapping();
    }
}

这是Controller

package SpringMVC.Controller;
import SpringMVC.pojo.Person;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
@RequestMapping("Person")
@Controller
@ResponseBody
public class JsonController {
    @PostMapping("data1")
    public String data1(@RequestBody Person person) {
        System.out.println("Person:" + person);
        return person.toString();
    }
}

这是实体类

package SpringMVC.pojo;
import lombok.Data;
@Data
public class Person {
    private String name;
    private int age;
    private String gender;
}

这是pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

最后是Apifox发送的post请求

31-Oct-2024 00:01:10.942 警告 [http-nio-8080-exec-2] org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver.logException Resolved [org.springframework.web.HttpMediaTypeNotSupportedException: Content-Type 'application/json;charset=UTF-8' is not supported]

这到底是是为什么啊
