XML REST服务
如果classpath下存在Jackson XML扩展（ jackson-dataformat-xml.jar ），它会被用来渲染XML响应，示例和JSON的非常相似。想要使用它，只需为你的项目添加以下依赖：
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>你可能还需要添加Woodstox的依赖，它比JDK提供的默认StAX实现快很多，并且支持良好的格式化输出，提高了namespace处理能力：(实践中发现org.springframework.boot.spring-boot-dependencies并没有定义此依赖，所以使用的时候需要制定版本号)
<dependency>
<groupId>org.codehaus.woodstox</groupId>
<artifactId>woodstox-core-asl</artifactId>
</dependency>如果Jackson的XML扩展不可用，Spring Boot将使用JAXB（JDK默认提供），不过 MyThing 需要注解 @XmlRootElement 或 @JacksonXmlRootElement ：
@XmlRootElement
public class MyThing {
private String name;
// .. getters and setters
}实验
