Xstream 解析xml文件内容

Posted 2020-10-31 SheaChen

刚刚接手的一个项目，接到一个对接用户数据的需求，对方使用的是xml格式来传输文件，特此记下解析该类文件的方法

public interface XmlResolver<T> {
    XStream builder();

    default T parse(String xml){
        return (T) builder().fromXML(xml);
    }

    default T resolver(String xml){
        return parse(xml);
    }
}
    //测试类
public class TestMain {

    private String name;
    private String address;
    private List<TestPerson> personList;

    public static void main(String[] args) {
        XmlResolver<TestMain> testMainXmlResolver = () -> {
            {
                XStream xStream = new XStream();
                xStream.alias("GetInvoiceResult", TestMain.class);
                xStream.alias("ItemRecord", TestPerson.class);
                return xStream;
            }
        };

       String xml = "<GetInvoiceResult>\n" +
                "        <name>string</name>\n" +
                "        <address>string</address>\n" +
                "        <personList>\n" +
                "          <ItemRecord>\n" +
                "            <name>string</name>\n" +
                "            <age>string</age>\n" +
                "          </ItemRecord>\n" +
                "          <ItemRecord>\n" +
                "            <name>string</name>\n" +
                "            <age>string</age>\n" +
                "          </ItemRecord>\n" +
                "        </personList>\n" +
                "      </GetInvoiceResult>\n"
                ;
        TestMain testMain = testMainXmlResolver.parse(xml);
        System.out.println(testMain);
    }
}
