[英]How can I extract content between two XML tags as text using Jackson?
我有一个带有以下模板的XML:
<tag1 attr1="value1" attr2="value2">
<tag2> text </tag2>
<tag3> another text </tag3>
</tag1>
我想将此xml提取到POJO中,该POJO具有2个文本字段作为String
和2个属性字段,但是我不太了解如何使用JacksonXmlText
。
首先,从一些教程开始。 例如,请在此页面上看看: 使用Jackson将XML转换为JSON 。
一些关键点:
com.fasterxml.jackson.dataformat.xml.XmlMapper
来序列化/反序列化XML
com.fasterxml.jackson.dataformat.xml.annotation
您的代码如下所示:
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;
public class Main {
public static void main(String[] args) throws Exception {
XmlMapper mapper = new XmlMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
Tag1 tag1 = new Tag1();
tag1.setTag2("text");
tag1.setTag3("another text");
tag1.setAttribute1("value1");
tag1.setAttribute2("value2");
String xml = mapper.writeValueAsString(tag1);
System.out.println(xml);
System.out.println(mapper.readValue(xml, Tag1.class));
}
}
@JacksonXmlRootElement(localName = "tag1")
class Tag1 {
private String attribute1;
private String attribute2;
private String tag2;
private String tag3;
@JacksonXmlProperty(isAttribute = true)
public String getAttribute1() {
return attribute1;
}
public void setAttribute1(String attribute1) {
this.attribute1 = attribute1;
}
@JacksonXmlProperty(isAttribute = true)
public String getAttribute2() {
return attribute2;
}
public void setAttribute2(String attribute2) {
this.attribute2 = attribute2;
}
public String getTag2() {
return tag2;
}
public void setTag2(String tag2) {
this.tag2 = tag2;
}
public String getTag3() {
return tag3;
}
public void setTag3(String tag3) {
this.tag3 = tag3;
}
@Override
public String toString() {
return "Tag1{" +
"attribute1='" + attribute1 + '\'' +
", attribute2='" + attribute2 + '\'' +
", tag2='" + tag2 + '\'' +
", tag3='" + tag3 + '\'' +
'}';
}
}
上面的代码打印:
<tag1 attribute1="value1" attribute2="value2">
<tag2>text</tag2>
<tag3>another text</tag3>
</tag1>
Tag1{attribute1='value1', attribute2='value2', tag2='text', tag3='another text'}
