Jackson XML

1 添加依賴
2 XML轉對象
3 對象轉XML
4 根據路徑讀取

1 添加依賴

<dependency><groupId>com.fasterxml.jackson.dataformat</groupId><artifactId>jackson-dataformat-xml</artifactId><version>2.11.3</version>
</dependency>

package com.xu.entity;import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;
import lombok.Data;import java.io.Serializable;@Data
@JacksonXmlRootElement(localName = "Data")
public class XmlEntity implements Serializable {private static final long serialVersionUID = 1L;@JsonProperty("Id")private String id;@JsonProperty("Name")private String name;@JsonProperty("Body")private Object body;}

package com.xu.entity;import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Data;import java.io.Serializable;
import java.util.Date;@Data
public class XmlData implements Serializable {private static final long serialVersionUID = 1L;@JsonProperty("Code")private int code = 1;@JsonProperty("Time")private long name = new Date().getTime();}

2 XML轉對象

package com.xu;import cn.hutool.json.JSONUtil;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import com.fasterxml.jackson.dataformat.xml.ser.ToXmlGenerator;
import com.xu.entity.XmlData;
import com.xu.entity.XmlEntity;
import org.junit.Test;
import org.springframework.boot.test.context.SpringBootTest;@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class UnitTest {@Testpublic void xml2bean() throws Exception {String xml = "<?xml version='1.0' encoding='UTF-8'?><Data><Id>1</Id><Name>test</Name><Body><Code>1</Code><Time>1715755993269</Time></Body></Data>";XmlMapper mapper = new XmlMapper();XmlEntity entity = mapper.readValue(xml, XmlEntity.class);System.out.println(JSONUtil.toJsonPrettyStr(entity));}}

3 對象轉XML

package com.xu;import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import com.fasterxml.jackson.dataformat.xml.ser.ToXmlGenerator;
import com.xu.entity.XmlData;
import com.xu.entity.XmlEntity;
import org.junit.Test;
import org.springframework.boot.test.context.SpringBootTest;@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class UnitTest {@Testpublic void bean2xml() throws Exception {XmlEntity test = new XmlEntity();test.setId("1");test.setName("test");test.setBody(new XmlData());XmlMapper mapper = new XmlMapper();mapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION, true);String xml = mapper.writeValueAsString(test);System.out.println(xml);}}

4 根據路徑讀取

package com.xu;import cn.hutool.json.JSONUtil;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import com.fasterxml.jackson.dataformat.xml.ser.ToXmlGenerator;
import com.xu.entity.XmlData;
import com.xu.entity.XmlEntity;
import org.junit.Test;
import org.springframework.boot.test.context.SpringBootTest;@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class UnitTest {@Testpublic void getByPath() throws Exception {String xml = "<?xml version='1.0' encoding='UTF-8'?><Data><Id>1</Id><Name>test</Name><Body><Code>1</Code><Time>1715755993269</Time></Body></Data>";XmlMapper mapper = new XmlMapper();JsonNode node = mapper.readTree(xml);JsonNode code = node.at("/Name");System.out.println(code.asText());}}
