xml转java_jackson-dataformat-xml

pom.xml

<dependency>
  <groupId>com.fasterxml.jackson.dataformat</groupId>
  <artifactId>jackson-dataformat-xml</artifactId>
  <version>2.9.5</version>
</dependency>

TypeReference与Type

import com.fasterxml.jackson.core.type.TypeReference;  //能够定义返回值类型比如
xmlMapper.readValue(xmlStr, new TypeReference<RefundRequest>(){});  //其返回值就为RefundRequest
Type
java.lang.reflect.Type  //返回类的具体类型

 

private final Type type;//别个地方传进来的
return xmlMapper.readValue(responseBody.charStream(),new TypeReference<T>(){
	@Override
	public Type getType() {
		return type;
	}
});

有时不指定Type会报转化失败

利用XmlMapper将字符串转化为java

import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import com.fasterxml.jackson.module.jaxb.JaxbAnnotationModule;
@Test
public void test(){
	String xmlStr = "<xml><appid>appId</appid><mch_id>mchId</mch_id><nonce_str>nonce</nonce_str><sign>signature</sign" +
			"><sign_type>HMAC-SHA256</sign_type><transaction_id>flowNo</transaction_id><out_refund_no>refundTradeNo" +
			"</out_refund_no><total_fee>100</total_fee><refund_fee>200</refund_fee><refund_desc>refundReason</refund_desc" +
			"></xml>";
	XmlMapper xmlMapper = new XmlMapper();
	xmlMapper.registerModule(new JaxbAnnotationModule());
	xmlMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
	xmlMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
	RefundRequest readValue=null;
	try {
		readValue = xmlMapper.readValue(xmlStr, new TypeReference<RefundRequest>(){
		});
	} catch (IOException e) {
		e.printStackTrace();
	}
	System.out.println("==============="+readValue.getFlowNo());
}
