YAML解析为linkedHashMap，而不解析为JAVABean

Question

我有一个YAML，应该将其解析为JAVA POJO对象，而不是抛出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课是：

public class MyType {

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

并使用读取YAML：

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

理想情况下，如果没有数据，我希望有一个空数组。

Answer 1

使用此

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