Xstream是一个库, 用于将对象序列化为xml, 反之亦然, 而无需任何映射文件。注意, castor需要一个映射文件。
XStreamMarshaller类提供了将对象封送为xml的工具, 反之亦然。
1.maven GAV（1.4.11.1版本才兼容）：
<dependency>
<groupId>com.thoughtworks.xstream</groupId>
<artifactId>xstream</artifactId>
<version>1.4.11.1</version>
</dependency>2.POJO类：
package com.yang.alibabamysql.domain.bo;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import lombok.Data;
import java.util.List;
@XStreamAlias(value = "man", impl = Man.class)
@Data
public class Man {
@XStreamAlias("id")
private Long id;
@XStreamAlias("name")
private String name;
@XStreamAlias("sonList")
protected List<Son> sonList;
@XStreamAlias(value = "son", impl = Son.class)
@Data
public static class Son {
@XStreamAlias("id")
private Long id;
@XStreamAlias("name")
private String name;
}
}3.配置类：
package com.yang.alibabamysql.config;
import com.thoughtworks.xstream.io.naming.NoNameCoder;
import com.thoughtworks.xstream.io.xml.Xpp3Driver;
import com.yang.alibabamysql.domain.bo.Man;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.oxm.xstream.XStreamMarshaller;
@Configuration
public class XStreamMarshallerConfig {
@Bean
public XStreamMarshaller getXStreamMarshaller() {
XStreamMarshaller xStreamMarshaller = new XStreamMarshaller();
xStreamMarshaller.setStreamDriver(new Xpp3Driver(new NoNameCoder()));
xStreamMarshaller.setAnnotatedClasses(Man.class, Man.Son.class);
xStreamMarshaller.setAutodetectAnnotations(true);
return xStreamMarshaller;
}
}4.测试类：
package com.yang.alibabamysql.controller;
import com.google.common.collect.Lists;
import com.thoughtworks.xstream.io.naming.NoNameCoder;
import com.thoughtworks.xstream.io.xml.Xpp3Driver;
import com.yang.alibabamysql.AlibabaMysqlApplicationTests;
import com.yang.alibabamysql.domain.bo.Man;
import org.springframework.oxm.xstream.XStreamMarshaller;
import java.util.ArrayList;
class UserControllerTest extends AlibabaMysqlApplicationTests {
private static final XStreamMarshaller xStreamMarshaller;
static {
xStreamMarshaller = new XStreamMarshaller();
xStreamMarshaller.setStreamDriver(new Xpp3Driver(new NoNameCoder()));
xStreamMarshaller.setAnnotatedClasses(Man.class, Man.Son.class);
xStreamMarshaller.setAutodetectAnnotations(true);
}
public static void marshal() {
Man.Son son = new Man.Son();
son.setId(2L);
son.setName("ypw");
ArrayList<Man.Son> sonArrayList = Lists.newArrayList(son);
Man man = new Man();
man.setId(1L);
man.setName("yjx");
man.setSonList(sonArrayList);
System.err.println(xStreamMarshaller.getXStream().toXML(man));
public static void unmarshal() {
String xml = "<man><id>1</id><name>yjx</name><sonList><son><id>2</id><name>ypw</name></son></sonList></man>";
Man man = (Man) xStreamMarshaller.getXStream().fromXML(xml);
System.err.println(man.getSonList().get(0).getName());
public static void main(String[] args) {
marshal();
System.out.println("=============");
unmarshal();
}输出：
<man>
<id>1</id>
<name>yjx</name>
<sonList>
<son>
<id>2</id>
<name>ypw</name>
</son>
</sonList>
</man>
