如何为sting数组创建用于XML String的Java POJO？

Question

我使用以下代码来实现上述但不起作用。请指南。

class ItemAttributes {
     @Element(name = "Binding")
     private String binding;
     @Element(name = "Brand")
     private String brand;
     @Element(name = "Color")
     private String color;
     @Element(name = "EAN")
     private String ean;
     @Element(name = "EANList")
     private EANList eanLists;
     @Element(name = "Feature")
     private List<String> feature;
 }

错误：

  

org.simpleframework.xml.core.InstantiationException：不能   为字段'feature'envate实例化接口java.util.List   java.util.List ItemAttributes.feature

改造中的我的XML日志响应：

"ItemAttributes": {
                    "Binding": "",
                    "Brand": "",
                    "Color": "",
                    "EAN": "",
                    "EANList": {
                        "EANListElement": ""
                    },
                    "Feature": ["","",""]
}

Answer 1

我自己也找到了答案。解决方案（至少在我的情况下）是定义一个可以实例化的具体类型，而不是一个抽象类型。

@ElementList(name = "Feature")
private ArrayList<String> feature;

而不是

 @Element(name = "Feature")
 private List<String> feature;
