Java uses snakeyaml read and write yaml-CodePudding

When I use snakeyaml to convert the yaml file into a class, the List object cannot be converted correctly.

The following can work

public class UserYaml {
    private Integer test1;
    private String test2;
    private Test3 test3;
//    private List<Test> test;
}

test1: 123
test2: "wqre"
test3:
  testt1: 1
  testt2: "asd"

#test4:
#  - test:
#      a: string
#      b: 3
#  - test:
#      a: integer
#      b: 4

CodePudding user response：

When you use space in yaml file means you have craeted children for that variable, so you must be create another class as Test3 and reference it to UserYaml class:

public class UserYaml {
    private Integer test1;
    private String test2;
    private List<Test3> test3;
}

public class Test3{
    private Integer testt1;
    private String testt2;
}

CodePudding user response：

Sorry, I didn't make it clear. I want Test4 to work correctly.

public class UserYaml {
private Integer test1;
private String test2;
private Test3 test3;
private List<Test> test;}

test1: 123
test2: "wqre"
test3:
  testt1: 1
  testt2: "asd"

test4:
  - test:
      a: string
      b: 3
  - test:
      a: integer
      b: 4
