Serialization 使用XmlMapper序列化递归或复合对象

我在build.gradle文件中使用以下jackson xml依赖项。 “com.fasterxml.jackson.dataformat:jackson dataformat xml:2.11.3”

我的复合类如下所示：

  @Data
    @NoArgsConstructor
    @AllArgsConstructor
    class Person {
        private int noOfkids;
        private String spouseName;
        private List<Person> children = new ArrayList<>();
        
        public void addChildren(Person p) {
            children.add(p);
            
        }
}

<Person>
    <noOfkids>2</noOfkids>
    <spouseName>spouse</spouseName>
    <children>
       <noOfkids>1</noOfkids>
       <spouseName>child1 - spouse</spouseName>
       <children>
           <noOfkids>2</noOfkids>
           <spouseName>childOfChild1 - spouse</spouseName>
        </children>
    </children>
    </children>
       <noOfkids>1</noOfkids>
       <spouseName>child2 - spouse</spouseName>
    <children/>
</Person>

<Person>
  <noOfkids>2</noOfkids>
  <spouseName>spouse</spouseName>
  <children><children><noOfkids>1</noOfkids><spouseName>child1 - spouse</spouseName><children>
    <children><noOfkids>2</noOfkids><spouseName>childOfChild1 - spouse</spouseName><children/></children></children>
    </children><children><noOfkids>1</noOfkids><spouseName>child2 - spouse</spouseName><children/>
    </children></children>
</Person>

我期望输出如下：

  @Data
    @NoArgsConstructor
    @AllArgsConstructor
    class Person {
        private int noOfkids;
        private String spouseName;
        private List<Person> children = new ArrayList<>();
        
        public void addChildren(Person p) {
            children.add(p);
            
        }
}

<Person>
    <noOfkids>2</noOfkids>
    <spouseName>spouse</spouseName>
    <children>
       <noOfkids>1</noOfkids>
       <spouseName>child1 - spouse</spouseName>
       <children>
           <noOfkids>2</noOfkids>
           <spouseName>childOfChild1 - spouse</spouseName>
        </children>
    </children>
    </children>
       <noOfkids>1</noOfkids>
       <spouseName>child2 - spouse</spouseName>
    <children/>
</Person>

<Person>
  <noOfkids>2</noOfkids>
  <spouseName>spouse</spouseName>
  <children><children><noOfkids>1</noOfkids><spouseName>child1 - spouse</spouseName><children>
    <children><noOfkids>2</noOfkids><spouseName>childOfChild1 - spouse</spouseName><children/></children></children>
    </children><children><noOfkids>1</noOfkids><spouseName>child2 - spouse</spouseName><children/>
    </children></children>
</Person>

2.
配偶
1.
子女1-配偶
2.
子女1-配偶
1.
子女2-配偶

但我得到的序列化xml如下所示：

  @Data
    @NoArgsConstructor
    @AllArgsConstructor
    class Person {
        private int noOfkids;
        private String spouseName;
        private List<Person> children = new ArrayList<>();
        
        public void addChildren(Person p) {
            children.add(p);
            
        }
}

<Person>
    <noOfkids>2</noOfkids>
    <spouseName>spouse</spouseName>
    <children>
       <noOfkids>1</noOfkids>
       <spouseName>child1 - spouse</spouseName>
       <children>
           <noOfkids>2</noOfkids>
           <spouseName>childOfChild1 - spouse</spouseName>
        </children>
    </children>
    </children>
       <noOfkids>1</noOfkids>
       <spouseName>child2 - spouse</spouseName>
    <children/>
</Person>

<Person>
  <noOfkids>2</noOfkids>
  <spouseName>spouse</spouseName>
  <children><children><noOfkids>1</noOfkids><spouseName>child1 - spouse</spouseName><children>
    <children><noOfkids>2</noOfkids><spouseName>childOfChild1 - spouse</spouseName><children/></children></children>
    </children><children><noOfkids>1</noOfkids><spouseName>child2 - spouse</spouseName><children/>
    </children></children>
</Person>

2.
配偶
1子女1-配偶
2儿童1-配偶
1子女2-配偶

有人能帮我解决这个问题吗？

如果我使用JAXB，这很好。StringWriter编写器=新的StringWriter（）；JAXBContext context=JAXBContext.newInstance（Person.class）；Marshaller m=context.createMarshaller（）；m、 封送处理（新JAXBElement（新QName（Person.class.getSimpleName（）），Person.class，p1），编写器）；System.out.println（writer.toString（））；//这是给我想要的输出
