YAML 解析为 linkedHashMap 而不是 JAVABean

Question

我有一个 YAML 应该被解析为 JAVA POJO 对象，而不是抛出一个 java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to <mytype>。 YAML 如下：

--- 
- 
  count: 1
  indicies: 
    - be-log-2018.09.20
  searchText: someText
  services: 
    - um
    - sa
- 
  count: 2
  searchText: someMoreText
  services: 
    - um2
    - sa2
- 
  count: 2
  searchText: someMoreText

我的 POJO class 是：

public class MyType {

    private int count;
    private String searchText;
    private String[] services;
    private String[] indicies;

并使用 :

阅读 YAML

ObjectMapper mapper= new ObjectMapper(new YAMLFactory());
mapper.readValue(new File(path), List.class);

理想情况下，如果没有给出数据，我希望有一个空数组。

Answer 1

使用这个

List<MyType> myTypeList = objectMapper.readValue(new File(path), new TypeReference<List<MyType>>() {});
