将带有转义双引号的字符串序列化为 XML

Question

我在尝试使用 jackson XmlMapper 将 Java 对象序列化为 XML 时遇到问题。

其中一个字段包含带有转义双引号的字符串，如下所示：

String example = "This is a string with \"escaped double quotes\"";

当我将对象传递给 XMLmapper （变量是包含示例字符串的对象）：

  XmlMapper xmlMapper = new XmlMapper();
  String xml = xmlMapper.writeValueAsString(variables);

这是我得到的输出：

some other tags
<example>This is a string with "escaped double quotes""This is a string with "escaped double quotes""This is a string with "escaped double quotes"</example>
some other tags

如何将带有转义双引号的字符串序列化为 XML 以获得正确的结果，即

<example>This is a string with "escaped double quotes"</example>
