@Data
// @JacksonXmlRootElement：指定生成xml根标签的名字；
@JacksonXmlRootElement(localName = "Class")
public class Group {
    private Teacher teacher;
    // @JacksonXmlElementWrapper：可用于指定List等集合类，外围标签名；
    @JacksonXmlElementWrapper(localName = "Students")
    // @JacksonXmlProperty：指定包装标签名，或者指定标签内部属性名；
    @JacksonXmlProperty(localName = "Stu")
    private List<Student> student;
    @Data
    @AllArgsConstructor
    public static class TeacherType {
        @JacksonXmlProperty(isAttribute = true, localName = "type")
        private String type;
        //@JacksonXmlText：指定当前这个值，没有xml标签包裹。
        // 这个值意义在于,一般这个值所在的类只有这一个正常属性，或者其他属性全部为  @JacksonXmlProperty(isAttribute = true,
        @JacksonXmlText
        private String grade;
    @Data
    public static class Teacher {
        @JacksonXmlProperty(localName = "TypeCode")

        private String id;
        private String name;
        private Integer age;
2.2、测试类

    @Test
    public void test() {
        Group group = new Group();
        Group.Teacher teacher = new Teacher();
        teacher.setTeacherTypeCode(new TeacherType("语文老师", "A"));
        teacher.setName("马老师");
        group.setTeacher(teacher);
        Student student = new Student();
        student.setId("001");
        student.setName("HealerJean");
        student.setAge(25);
        group.setStudent(Arrays.asList(student));
        String xml = XmlUtils.toXml(group);
        log.info("数据原文：【 {} 】", xml);
//XML标签名:使用骆驼命名的属性名，
xmlMapper.setPropertyNamingStrategy(PropertyNamingStrategy.UPPER_CAMEL_CASE);
<Class>
    <Teacher>
        <Name>马老师</Name>
        <TypeCode type="语文老师">A</TypeCode>
    </Teacher>
    <Students>
        <Stu stu_id="001">
            <Name>HealerJean</Name>
            <Age>25</Age>
        </Stu>
    </Students>
</Class>
自定义的转化转大写并加下划线，强制命令的不可以，比如下面的Class是强制命名的
 xmlMapper.setPropertyNamingStrategy(new UpperCaseSnackNamingStrategy());
<Class>
    <TEACHER>
        <NAME>马老师</NAME>
        <TypeCode type="语文老师">A</TypeCode>
    </TEACHER>
    <Students>
        <Stu stu_id="001">
            <NAME>HealerJean</NAME>
            <AGE>25</AGE>
        </Stu>
    </Students>
</Class>

3.1、XmlUtils

        SimpleModule module = new SimpleModule();
        xmlMapper.registerModule(module);
        xmlMapper.setDefaultUseWrapper(false);
        //字段为null，自动忽略，不再序列化
        xmlMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
        //XML标签名:使用骆驼命名的属性名，
        // xmlMapper.setPropertyNamingStrategy(PropertyNamingStrategy.UPPER_CAMEL_CASE);
        //转化成加下划线和大写
        xmlMapper.setPropertyNamingStrategy(new UpperCaseSnackNamingStrategy());
        //设置转换模式
        xmlMapper.enable(MapperFeature.USE_STD_BEAN_NAMING);
    public static String toXml(Object object) {
        try {
            return xmlMapper.writeValueAsString(object);
        } catch (JsonProcessingException e) {
            log.error("Xml转换失败", e);
            throw new RuntimeException("Xml转换失败", e);
    public static <T> T toObject(String xml, Class<T> c) {
        try {
            return xmlMapper.readValue(xml, c);
        } catch (IOException e) {
            log.error("Xml转换失败", e);
