使用Spring Rest模板时如何写出不可转换的消息体

import org.springframework.http.HttpInputMessage;
import org.springframework.http.HttpOutputMessage;
import org.springframework.http.MediaType;
import org.springframework.http.converter.AbstractHttpMessageConverter;
import org.springframework.http.converter.HttpMessageNotReadableException;
import org.springframework.http.converter.HttpMessageNotWritableException;

import java.io.IOException;

public class CustomHttpMessageConverter extends AbstractHttpMessageConverter<Object> {

    public CustomHttpMessageConverter() {
        super(MediaType.APPLICATION_JSON);
    }

    @Override
    protected boolean supports(Class<?> clazz) {
        // 判断是否支持读取和写入特定的对象类型
        return clazz.isAssignableFrom(YourObject.class);
    }

    @Override
    protected Object readInternal(Class<? extends Object> clazz, HttpInputMessage inputMessage) throws IOException, HttpMessageNotReadableException {
        // 实现请求消息体的自定义处理逻辑
        // 例如，可以将请求消息体转换为自定义的对象
        return null;
    }

    @Override
    protected void writeInternal(Object object, HttpOutputMessage outputMessage) throws IOException, HttpMessageNotWritableException {
        // 实现响应消息体的自定义处理逻辑
        // 例如，可以将自定义的对象转换为响应消息体
    }
}

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
    <property name="messageConverters">
        <list>
            <bean class="com.example.CustomHttpMessageConverter"/>
        </list>
