本文整理了Java中com.fasterxml.jackson.databind.JsonNode.longValue()方法的一些代码示例，展示了JsonNode.longValue()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。JsonNode.longValue()方法的具体详情如下：
包路径：com.fasterxml.jackson.databind.JsonNode
类名称：JsonNode
方法名：longValue

JsonNode.longValue介绍

[英]Returns 64-bit long value for this node, if and only if this node is numeric ( #isNumber returns true). For other types returns 0. For floating-point numbers, value is truncated using default Java coercion, similar to how cast from double to long operates.
[中]返回此节点的64位长值，当且仅当此节点为数字时（#isNumber返回true）。对于其他类型，返回0。对于浮点数，使用默认Java强制截断值，类似于从double到long的转换操作。

/**
 * Get a Long field from the JSON.
 *
 * @param json JSON document.
 * @param fieldName Field name to get.
 * @return Long value of field or null if not present.
 */
private Long getLongField(JsonNode json, String fieldName) {
  if (!json.has(fieldName)) {
    return null;
  }
  return json.get(fieldName).longValue();
}
