使用 Spring Boot 和 RestTemplate 使用嵌套的 JSON 数组

Question

我正在尝试使用返回以下 JSON 的 HTTP GET 请求在我的 Spring Boot 应用程序中使用 API。我遇到的问题是“playerentry”级别中包含一个 JSON 数组，其中包含未命名/未命名的球员和球队信息对。对于 Spring，通常会为 JSON 的每一层创建一个 java 类，并使用 @JsonProperty() 注释来指定从 JSON 的哪个部分生成 Java 对象。如果没有 JSON 数组中包含的对的名称，并且不确定如何为 playerentry 数组和包含的数组对正确设置 java 类，我一直无法使用 RestTemplate 和 RestTemplateBuilder 来使用这个 JSON。任何帮助将不胜感激。

Answer 1

这应该有效

class Roasterplayers {
    String lastUpdatedOn;
    List<PlayerEntry> playerentry;
}


class PlayerEntry {
    Player player;
    Team team;
}

class Player {

    @JsonProperty("ID")
    String id;
    @JsonProperty("LastName")
    String lastName;
    @JsonProperty("FirstName")
    String firstName;
}

class Team {
    @JsonProperty("ID")
    String id;
    @JsonProperty("City")
    String city;
    @JsonProperty("Name")
    String name;
    @JsonProperty("Abbreviation")
    String abbreviation;
}

确保每个字段都有 Setter 和 Getter
