使用RestTemplate发送Post请求

参数类

import com.alibaba.fastjson.annotation.JSONField;
import com.DbProperties;   //这是自定义的一个类
import lombok.Data;

@Data
public class TrafficCountPredictionParam {
    /**
     * 请求的唯一标识
     */
    @JSONField(name = "trace_id")
    private String traceId;

    @JSONField(name = "db_original")
    private DbProperties dbOriginal = new DbProperties();

    @JSONField(name = "db_statistics")
    private DbProperties dbStatistics = new DbProperties();

    /**
     * 路段ID,用逗号分隔
     */
    @JSONField(name = "unit_id")
    private String unitId;

    /**
     * 请求接口地址
     */
    private String address;

    @JSONField(name = "custom_days")
    private CustomDays customDays = new CustomDays();

    /**
     * 当前日期
     */
    @JSONField(name = "current_date")
    private String currentDate;

    /**
     * 时间类型
     */
    @JSONField(name = "time_type")
    private Integer timeType;


    @Data
    public static class CustomDays {
        /**
         * 开始日期
         */
        @JSONField(name = "start_date")
        private String startDate;
        /**
         * 结束日期
         */
        @JSONField(name = "end_date")
        private String endDate;
    }

}

代码实现:

private boolean predictionApi(String url, TrafficCountPredictionParam param, int count) {
		boolean flag = true;
		if (count == 0) {
			RestTemplate template = new RestTemplate();
			HttpHeaders headers = new HttpHeaders();
			headers.setContentType(MediaType.APPLICATION_JSON);
			String content = JSON.toJSONString(param);
			HttpEntity request = new HttpEntity<>(content, headers);

			final ResponseEntity responseEntity;
			try {
				responseEntity = template.postForEntity(url, request, String.class);
				final String body = responseEntity.getBody();
				final JSONObject responseBody = JSON.parseObject(body);
				final Object statue = responseBody.get("status");
				if (!"OK".equals(statue)) {
					flag = false;
				}
			} catch (Exception e) {
				e.printStackTrace();
				flag = false;
			}
		}
		return flag;
}
