首先，加入依赖包：
<!-- POJO->XML/JSON,XML/JSON->POJO --> <dependency> <groupId>com.fasterxml.jackson.dataformat</groupId> <artifactId>jackson-dataformat-xml</artifactId> <version>2.6.0</version> </dependency>
假设一个HTTP请求的返回为XML格式：
<returnsms> <returnstatus>Success</returnstatus> <message>ok</message> <remainpoint>11032</remainpoint> <taskID>4354699</taskID> <successCounts>1</successCounts> </returnsms>
简单地把这些XML转换为MAP对象的方法：
URL url = new URL("http://www.abc.com/yyy");
// 打开url连接
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
// 设置url请求方式 ‘get’ 或者 ‘post’
connection.setRequestMethod("POST");
// 发送
InputStream is = url.openStream();
// 转换返回值
@SuppressWarnings("unchecked")
Map<String,String> m = new XmlMapper().readValue(is,Map.class);
String returnstatus = m.get("returnstatus");
if ("Success".equals(returnstatus)) {// 返回成功
logger.info("成功!");
} else {
logger.error("失败! cause:{}",m.get("message"));
}
