JSON中使用Jersey+MOXY的变量类型

Question

{
    indexes:[
    {
       "name": "ABC",
       "value": "abcdef"
       "displayValue": "abcdef",
       "type": "string"
     },
     {
        "name": "XYZ",
        "value": 12345
        "displayValue": "12345",
        "type": "number"
     },
     ...
     ]
}

public class Index {
    String name;
    Object value;
    String displayValue;
    String type;
}

{
     indexes:[
     {
          "name": "ABC",
      "value": {
          "type": "xsd:string",
          "value": "abcdef"
      },
      "displayValue": "abcdef",
      "indexType": "string"
     },
     {
          "name": "XYZ",

          "value": {
            "type": "xsd:int",
            "value": 812501
        },
     "displayValue": "812501",
     "indexType": "number"
     },
     ...

有没有任何方法来实现我所需要的，“值”字段的变量类型值？

我不知道你的问题到底出在哪里。您使用的是什么JSON库？另外，您能提供更多关于您的索引类的细节吗？我不确定为什么您的setValue（对象值）需要做任何特殊的事情。如果我使用带有以下代码的Jackson json库：

public static void main(String[] args) throws JsonProcessingException {
    Index[] indices = new Index[2];
    indices[0] = new Index();
    indices[0].name = "ABC";
    indices[0].value = "abcdef";
    indices[0].displayValue = indices[0].value + "";
    indices[0].type = "string";
    indices[1] = new Index();
    indices[1].name = "XYZ";
    indices[1].value = 123456;
    indices[1].displayValue = indices[1].value + "";
    indices[1].type = "number";
    System.out.println(new ObjectMapper().writeValueAsString(indices));
}

public static class Index {

    String name;
    Object value;
    String displayValue;
    String type;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Object getValue() {
        return value;
    }

    public void setValue(Object value) {
        this.value = value;
    }

    public String getDisplayValue() {
        return displayValue;
    }

    public void setDisplayValue(String displayValue) {
        this.displayValue = displayValue;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }
}

我得到以下输出：

[{"name":"ABC","value":"abcdef","displayValue":"abcdef","type":"string"},
 {"name":"XYZ","value":123456,"displayValue":"123456","type":"number"}]

我相信这就是你要找的。
