在Jackson的反序列化过程中，如何在验证JSON负载时抛出异常？

import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.JsonDeserializer;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.deser.std.StdDeserializer;

import java.io.IOException;

public class CustomDeserializer extends StdDeserializer<Object> {

    public CustomDeserializer() {
        this(null);
    }

    public CustomDeserializer(Class<?> vc) {
        super(vc);
    }

    @Override
    public Object deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
        ObjectMapper mapper = (ObjectMapper) jsonParser.getCodec();
        JsonNode node = mapper.readTree(jsonParser);

        // 在这里进行验证JSON负载的逻辑判断
        if (!node.has("field1")) {
            throw new IllegalArgumentException("Missing required field: field1");
        }

        // 可以继续添加其他验证逻辑

        // 反序列化对象
        return mapper.treeToValue(node, Object.class);
    }
}

import com.fasterxml.jackson.databind.annotation.JsonDeserialize;

@JsonDeserialize(using = CustomDeserializer.class)
public class MyObject {
    private String field1;
    private String field2;

    // 省略getter和setter
}
