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

JsonParser.getText介绍

[英]Method for accessing textual representation of the current token; if no current token (before first call to #nextToken, or after encountering end-of-input), returns null. Method can be called for any token type.
[中]用于访问当前令牌的文本表示的方法；如果没有当前令牌（在第一次调用#nextToken之前，或在遇到输入结束之后），则返回null。方法可以为任何令牌类型调用。

代码示例

代码示例来源：origin: redisson/redisson

/**
 * Method that fetches next token (as if calling {@link #nextToken}) and
 * if it is {@link JsonToken#VALUE_STRING} returns contained String value;
 * otherwise returns null.
 * It is functionally equivalent to:
 *<pre>
 *  return (nextToken() == JsonToken.VALUE_STRING) ? getText() : null;
 *</pre>
 * but may be faster for parser to process, and can therefore be used if caller
 * expects to get a String value next from input.
 */
public String nextTextValue() throws IOException {
  return (nextToken() == JsonToken.VALUE_STRING) ? getText() : null;
}
