我有一个“示例”Pojo 类，如下所述。任何人都可以使用 Hymanson 将 Example 类的实例保存到 YAML 文件中。
public class Example {
String name;
int value;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getValue() {
return value;
}
public void setValue(int value) {
this.value = value;
}
}
}

Hymanson has a module that supports YAML. Ensure that you add the required dependencyto your project, then you can use it as following:
Hymanson 有一个支持 YAML的模块。确保您将所需的依赖项添加到您的项目中，然后您可以按如下方式使用它：
// Create an ObjectMapper mapper for YAML
ObjectMapper mapper = new ObjectMapper(new YAMLFactory());
// Write object as YAML file
mapper.writeValue(new File("/path/to/yaml/file"), example);
Alternatively you can write your object as a string:
或者，您可以将对象编写为字符串：
// Write object as YAML string
String yaml = mapper.writeValueAsString(example);
