如何在Java8和SpringBoot中解析YAML文件

Question

我有以下YAML文件：

customers:
  UniqueProductName1:
    SubscriptionPlan1:
      User1: {payment:150, limit: 200}
      User2: {payment:200, limit: 300}
      User3: {payment:60, limit: 100}
    SubscriptionPlan2:
      User1: {payment:150, limit: 200}
      User2: {payment:200, limit: 300}
      User5: {payment:150, limit: 200}
  UniqueProductName2:
    SubscriptionPlan1:
      User6: {payment:150, limit: 200}
      User7: {payment:200, limit: 300}
      User4: {payment:60, limit: 100}
    SubscriptionPlan2:
      User5: {payment:150, limit: 200}
      User8: {payment:200, limit: 300}
      User9: {payment:150, limit: 200}
    SubscriptionPlan3:
      User5: {payment:150, limit: 200}
      User8: {payment:200, limit: 300}
      User10: {payment:150, limit: 200}

如何获得UniqueProductName1.SubscriptionPlan1.User3.payment的值？ 在此yaml文件内容中没有描述UniqueProductName1是“产品”等内容的字段

我尝试使用杰克逊jar：

<dependency>
        <groupId>com.fasterxml.jackson.dataformat</groupId>
        <artifactId>jackson-dataformat-yaml</artifactId>
        <version>2.8.3</version>
</dependency>

我创建了以下Java bean：

MainYaml.java：

@Configuration
@EnableConfigurationProperties
@ConfigurationProperties("customers")
public class MainYaml {

    public List<CustomerProduct> customerProductList;

    //getter and setter

CustomerProduct.java :(我是否也需要在这里使用@configurationproperties注释？）

public class CustomerProduct{
    public String productName;
    public List<CustomerPlan> customerPlansList;

    //getter and setter

CustomerPlan.java：

public class CustomerPlan{
    public String planName;
    public List<Customer> customerList;

    //getter and setter

Customer.java：

@Component
public class Customer{
    public String customerName;

    public CustomerDetail customerDetail ;

    //getter and setter

CustomerDetail.java：

public class CustomerDetail {

@JsonProperty
public String payment;

@JsonProperty
public String limit;
