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

JsonNode.getTextValue介绍

[英]Method to use for accessing String values. Does NOT do any conversions for non-String value nodes; for non-String values (ones for which #isTextual returns false) null will be returned. For String values, null is never returned (but empty Strings may be)
[中]用于访问字符串值的方法。不为非字符串值节点进行任何转换；对于非字符串值（即#isTextual返回false的值），将返回null。对于字符串值，永远不会返回null（但可能会返回空字符串）

代码示例

/** Extracts text value associated to key from the container JsonNode. */
private static String getOptionalText(JsonNode container, String key) {
 JsonNode jsonNode = container.get(key);
 return jsonNode != null ? jsonNode.getTextValue() : null;
}
