反序列化JSON复杂到Java，类嵌套在多个层次深

我努力使黄瓜输出的JSON转换成一个Java对象。这包含嵌套深四个层次的对象，而我无法反​​序列化它。我目前使用杰克逊，但广纳建议。这里是我的Json代码：

我已经尝试了许多不同的方法。首先我用嵌套的内部类，但似乎你必须让他们静，我怕是行不通的，因为我有一个在同一个对象的多个实例（多个“元素” -objects根，例如）。然后我试图把它们放在单独的类，使用JSON注解。在此处，这让我（省略制定者）：

public class CucumberUitvoer {
    private String name;
    private String description;
    private String id;
    private String keyword;
    private String uri;
    private int line;
    @JsonProperty("elements")
    private List<FeatureObject> elements;

    public CucumberUitvoer(){}
}

public class FeatureObject {
    private String name;
    private String description;
    private String id;
    private String type;
    private String keyword;
    private int line;
    @JsonProperty("steps")
    private List<StepObject> steps;

    public FeatureObject() {
    }
}

public class StepObject {
    @JsonProperty("result")
    private ResultObject result;
    private String name;
    private String given;
    private String location;
    private String keyword;
    private int line;
    @JsonProperty("match")
    private MatchObject match;

    public StepObject(){}
}

public class ResultObject {
    private int duration;
    private String status;

    public ResultObject(){}
}

public class MatchObject {
    @JsonProperty("arguments")
    private List<ArgumentObject> arguments;
    private String location;

    public MatchObject(){}
}

public class ArgumentObject {
    private String val;
    private String offset;

    public ArgumentObject(){}
}

为了清楚起见，这里的如何嵌套作品的类图。

该解决方案使我有以下错误：

com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of nl.icaprojecten.TestIntegratieQuintor.JSONInterpreter.CucumberUitvoer out of START_ARRAY token

这里是做实际映射代码：

ObjectMapper mapper = new ObjectMapper();
    mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

    CucumberUitvoer obj1 = null;
    try {
        obj1 = mapper.readValue(json, CucumberUitvoer.class);
    } catch (IOException e) {
        e.printStackTrace();
    }

是否有一个快速修复这种方法，使其工作，或者我应该尝试完全不同的东西？
