本文整理了Java中com.fasterxml.jackson.databind.JsonNode.isInt()方法的一些代码示例，展示了JsonNode.isInt()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.isInt()方法的具体详情如下：
包路径：com.fasterxml.jackson.databind.JsonNode
类名称：JsonNode
方法名：isInt

JsonNode.isInt介绍

[英]Method that can be used to check whether contained value is a number represented as Java int. Note, however, that even if this method returns false, it is possible that conversion would be possible from other numeric types -- to check if this is possible, use #canConvertToInt() instead.
[中]方法，该方法可用于检查所包含的值是否为表示为Javaint的数字。但是，请注意，即使此方法返回false，也有可能从其他数值类型进行转换——要检查这是否可行，请使用#canConvertToInt（）代替。
