YAML被解析为linkedHashMap而不是JAVABean

Question

我有一个YAML，它应该被解析为JAVA对象，而不是抛出一个java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to <mytype>。“青年反洗钱法”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课程是：

public class MyType {

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

阅读“青年反洗钱”时：

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

理想情况下，如果没有提供数据，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>>() {});
