如何使用json属性将json映射到java对象

Question

我无法在java对象中映射此json。问题是我无法映射值v0。1.0到我的java对象任何人都可以帮助我如何将这个json映射到java对象。我不能用v0声明变量名。因此我使用json属性注释。但这对我来说不管用

如何使用此json生成java对象：

{
    "availableVariants": {
        "v0.1.0": {
            "resourceName": "raja",
            "get": "www.google.com",
            "deltaGet": "",
            "post": null,
            "put": null,
            "delete": null
        },
        "v1.1.0": {
            "resourceName": "raja",
            "get": "www.google.com",
            "deltaGet": "",
            "post": null,
            "put": null,
            "delete": null
        }
    }
}

I am not able to make java object for this json .

如果将“v0.1.0”和“v1.1.0”视为地图中的键而不是对象的属性，问题会变得更简单吗？试试这样：

public class Resource {
    private String resourceName;
    private String get;
    private String deltaGet;
    private String post;
    private String put;
    private String delete;

    // public getters and setters
}

public class VariantInfo {
    // resources indexed by version
    private Map<String, Resource> availableVariants; 
    // public getter and setter
}

public VariantInfo parseVariants(String json) {
    ObjectMapper objectMapper = (wherever your Jackson object mapper comes from);
    return objectMapper.readValue(json, VariantInfo.class);
}
