Jackson XML轉(zhuǎn)JSON是一種非常方便的數(shù)據(jù)格式轉(zhuǎn)換方法，它可以將XML格式的數(shù)據(jù)轉(zhuǎn)換為JSON格式的數(shù)據(jù)。以下是一些關(guān)于如何使用Jackson庫將XML轉(zhuǎn)換為JSON的簡單示例。

import java.io.IOException;
import java.io.StringWriter;
import com.fasterxml.jackson.core.JsonGenerationException;
import com.fasterxml.jackson.core.JsonParseException;
import com.fasterxml.jackson.databind.JsonMappingException;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.databind.json.JsonMapper;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;
public class JacksonXmlToJson {
public static void main(String[] args) throws JsonParseException, JsonMappingException, IOException {
JacksonXmlToJson jacksonXmlToJson = new JacksonXmlToJson();
// XML to JSON Conversion
String xml = "Tom32";
String json = jacksonXmlToJson.convertXmlToJson(xml);
System.out.println("XML: " + xml);
System.out.println("JSON: " + json);
}
public String convertXmlToJson(String xmlString) throws JsonParseException, JsonMappingException, IOException {
ObjectMapper objectMapper = new XmlMapper();
JsonNode node = objectMapper.readTree(xmlString.getBytes());
ObjectMapper jsonMapper = new JsonMapper();
StringWriter writer = new StringWriter();
jsonMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
jsonMapper.writeValue(writer, node);
return writer.toString();
}
}

在上面的示例中，我們使用Jackson的XmlMapper將傳遞的XML字符串轉(zhuǎn)換為JsonNode對(duì)象。我們?nèi)缓笫褂肑ackson的JsonMapper將JsonNode對(duì)象轉(zhuǎn)換回JSON字符串。

使用此方法，可以輕松地將大量XML數(shù)據(jù)轉(zhuǎn)換為JSON，而無需進(jìn)行復(fù)雜的手動(dòng)轉(zhuǎn)換。
