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

JsonNode.asInt介绍

[英]Method that will try to convert value of this node to a Java int. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.

If representation can not be converted to an int (including structured types like Objects and Arrays), default value of 0 will be returned; no exceptions are thrown.
[中]方法，该方法将尝试将此节点的值转换为Java int；布尔值转换为0（false）和1（true），字符串使用默认的Java语言整数解析规则进行解析。
如果表示不能转换为int（包括对象和数组等结构化类型），则返回默认值0；没有抛出异常。
