One, pom dependence

    <!-- 将xml包解析成Map -->
        <dependency>
            <groupId>dom4j</groupId>
            <artifactId>dom4j</artifactId>
            <version>1.6.1</version>
        </dependency>

        <!-- 将Map解析成XML包 -->
        <dependency>

Two, entity class code

xml data packet format


note:
1. The media id parameter of the thumbnail is the id obtained through the multimedia file uploaded through the interface in the material management;
2. The MusicUrl is now opened in the browser to see if it can be played, I am downloading the music file ( mp3 format) uploaded to FastDFS, the returned path can be opened and played in the browser.
3. Note that the parameter name is the name in the xml format, the following parameter explanation MusicUrl is written as MusicURL, so it cannot be parsed, and should be written according to the name in the xml.
BUG :
It is best to write all the above parameters, because I thought that the HQMusicUrl parameter is not necessary, so if I didn't write it, the official account could not be parsed, and it kept returning "the official account failed".

public class Music {
