具有以下架构的类的.yaml结构应该是什么

Question

我有一个java类，用于在读取.yml文件后设置对象。我遇到了无法在.yml文件中设置值的问题。下面是类的表示。映射是一个列表，同样有两个键值对。Offices是字符串列表，而assignment只是一个字符串。

public class System {

    public Employee employee;

    public List<Mapping> mappings;


    public System(Employee emplyoee, List<Mapping> mappings) {
        super();
        this.employee = employee;
        this.mappings = mappings;
    }

    public Employee getEmployee() {
        return employee;
    }

    public void setSankalp(Employee sankalp) {
        this.employee = sankalp;
    }

    public List<Mapping> getMappings() {
        return mappings;
    }

    public void setMappings(List<Mapping> mappings) {
        this.mappings = mappings;
    }

    public static class Employee {

        public String name;
        public String work;


        public Employee(String name, String work) {
            super();
            this.name = name;
            this.work = work;
        }
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String getWork() {
            return work;
        }
        public void setWork(String work) {
            this.work = work;
        }
    }

    public static class Mapping {

        public String assignment;
        public List<String> offices;


        public Mapping(String assignment, List<String> offices) {
            super();
            this.assignment= assignment;
            this.offices= offices;
        }
        public String getAssignment() {
            return assignment;
        }
        public void setAssignment(String assignment) {
            this.assignment= assignment;
        }
        public List<String> getOffices() {
            return offices;
        }
        public void setOffices(List<String> offices) {
            this.offices= offices;
        }
    }
}

public class SystemWrapper {
    public System system;

    public SystemWrapper(System system) {
        super();
        this.system = system;
    }

    public System getSystem() {
        return system;
    }

    public void setSystem(System system) {
        this.system = system;
    }
}

.yaml的结构可以是什么？我正在尝试使用下面的.yaml，它根本不起作用。

system:
 employee:
  name: "andy"
  work: "eng"
 mappings:
  - offices: ["new york", "dc"]
    assignment: "full time"

Answer 1

尝试以下操作：

system:
 employee:
  name: "andy"
  work: "eng"
 mappings:
   -mapping:
     offices: ["new york", "dc"]
     assignment: "full time"
   -mapping:
     offices: ["yorkshire", "dc"]
     assignment: "part time"

在您代码中，mappings是一个Mapping类的列表。

Answer 2

您的yaml映射看起来没问题。我在示例Spring应用程序中尝试了它，它起作用了。我必须改变的是从类中删除构造器，并保留默认值。所以试着去掉这个：

public System(Employee emplyoee, List<Mapping> mappings) {
...
public Mapping(String assignment, List<String> offices) {
...
public Employee(String name, String work) {
...
public SystemWrapper(System system) {

此外，您还在setEmployee中拼写错误

public Employee getEmployee() {
    return employee;
}

public void setSankalp(Employee sankalp) {
    this.employee = sankalp;
}
