[英]Serializing string with escaped double quotes to XML
I have a problem trying to serialize a Java Object to XML using jackson XmlMapper.我在尝试使用 jackson XmlMapper 将 Java 对象序列化为 XML 时遇到问题。
One of the fields contains a string with escaped double quotes, like this:其中一个字段包含一个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\\"";
When i pass object to XMLmapper (variables is the object containing example string):当我将对象传递给 XMLmapper 时(变量是包含示例字符串的对象):
XmlMapper xmlMapper = new XmlMapper();
String xml = xmlMapper.writeValueAsString(variables);
this is the output i get: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
How can i serialize a string with escaped doubled quotes to XML achieving proper result, ie我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>
Then: "Sorry, cannot reproduce"!然后:“对不起,无法复制”!
