根据 json { "spuCode": "", "skuCode": 73591582, "salesGridIds": [ 50000022 ], "selectedSkuCodes": [] } 利用httpclient 生成java对象 访问接口 https://seller.kuailv.meituan.com/competitiveness/wechat/r/gridCompareList

以下是一个使用HttpClient访问该接口并生成Java对象的示例：

import com.fasterxml.jackson.databind.ObjectMapper;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClientBuilder;
import java.io.IOException;
import java.util.Arrays;

public class Example {
    public static void main(String[] args) throws IOException {
        // 创建HttpClient对象
        HttpClient client = HttpClientBuilder.create().build();

        // 构造请求体
        String requestBody = "{\"spuCode\":\"\",\"skuCode\":73591582,\"salesGridIds\":[50000022],\"selectedSkuCodes\":[]}";
        StringEntity entity = new StringEntity(requestBody, ContentType.APPLICATION_JSON);

        // 构造HttpPost对象
        HttpPost post = new HttpPost("https://seller.kuailv.meituan.com/competitiveness/wechat/r/gridCompareList");
        post.setHeader("Authorization", "Bearer {token}");
        post.setEntity(entity);

        // 发送请求并获取响应
        HttpResponse response = client.execute(post);

        // 解析响应结果
        HttpEntity responseEntity = response.getEntity();
        byte[] bytes = responseEntity.getContent().readAllBytes();

        // 将结果转换为Java对象
        ObjectMapper mapper = new ObjectMapper();
        Data data = mapper.readValue(bytes, Data.class);

        // 打印Java对象
        System.out.println(data);
    }

    static class Data {
        private String spuCode;
        private long skuCode;
        private Long[] salesGridIds;
        private Object[] selectedSkuCodes;

        public String getSpuCode() {
            return spuCode;
        }

        public void setSpuCode(String spuCode) {
            this.spuCode = spuCode;
        }

        public long getSkuCode() {
            return skuCode;
        }

        public void setSkuCode(long skuCode) {
            this.skuCode = skuCode;
        }

        public Long[] getSalesGridIds() {
            return salesGridIds;
        }

        public void setSalesGridIds(Long[] salesGridIds) {
            this.salesGridIds = salesGridIds;
        }

        public Object[] getSelectedSkuCodes() {
            return selectedSkuCodes;
        }

        public void setSelectedSkuCodes(Object[] selectedSkuCodes) {
            this.selectedSkuCodes = selectedSkuCodes;
        }

        @Override
        public String toString() {
            return "Data{" +
                    "spuCode='" + spuCode + '\'' +
                    ", skuCode=" + skuCode +
                    ", salesGridIds=" + Arrays.toString(salesGridIds) +
                    ", selectedSkuCodes=" + Arrays.toString(selectedSkuCodes) +
                    '}';
        }
    }
}

其中，{token}需要替换成实际的token。注意，这里使用了Jackson库将JSON字符串转换为Java对象。在Data类中，数组类型的属性需要使用包装类型，否则在转换时会报错。
