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

JsonNode.asBoolean介绍

[英]Method that will try to convert value of this node to a Java boolean. JSON booleans map naturally; integer numbers other than 0 map to true, and 0 maps to false and Strings 'true' and 'false' map to corresponding values.

If representation can not be converted to a boolean value (including structured types like Objects and Arrays), default value of false 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布尔值。JSON布尔映射自然；0以外的整数映射为true，0映射为false，字符串“true”和“false”映射为相应的值。
如果表示不能转换为布尔值（包括对象和数组等结构化类型），则返回默认值false；没有抛出异常。
