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

JsonNode.getValueAsText介绍

[英]Method that will return valid String representation of the container value, if the node is a value node (method #isValueNode returns true), otherwise null.

Note: to serialize nodes of any type, you should call #toString instead.
[中]方法，该方法将返回容器值的有效字符串表示形式，如果该节点是值节点（方法#isValueNode返回true），否则为null。
注意：要序列化任何类型的节点，应该调用#toString。
