Question

我想使用Spring Boot @RequestBody注释将此JSON结构{ "male": { "id": "0001", "name": "Emma", "pet": "dog" }, "female": { "id": "0001", "name": "Cilia", "pet": "cat" } }绑定到Java HashMap数据结构。但是，spring boot无法将其绑定，但是如果我将json作为字符串接收并手动将其绑定到哈希表，它将成功。她是HashMap

public class Tickets {

    private HashMap<String, PeopleType> peopleTypes = new HashMap();
}

public class PeopleType {

    private String id;

    private String name;

    private String pet;
}

这是控制者

@PostMapping("/url")
public ResponseEntity bookTickets(@RequestBody Tickets tickets, HttpSession session) {
...
}

为简便起见，我删除了所有的Getter和Setters

Answer 1

尝试一下：

@PostMapping("/url")
public ResponseEntity bookTickets(@RequestBody Map<String, PeopleType> peopleTypes, HttpSession session) {
    Tickets tickets = new Tickets();
    tickets.setPeopleTypes(peopleTypes);
    ...
}

或，请尝试以下操作：

public class Tickets {
    private Map<String, PeopleType> peopleTypes = new HashMap<>();

    @JsonAnySetter
    public void addPeopleType(String type, PeopleType peopleType) {
        peopleTypes.put(type, peopleType);
    }
}

@PostMapping("/url")
public ResponseEntity bookTickets(@RequestBody Tickets tickets, HttpSession session) {
    ...
}
