java中如何查找两个JSON之间的差异？

Question

我有 2 个带有嵌套元素的大型 JSON，我需要找到这些 json 的差异。每个 Json 代表不同日期来自 LDAP 的数据。我正在研究 Jackson 的 JsonNode 类。该类的 Equals 方法可以比较 2 个 JsonNode，但它不返回差异。

感谢任何有关获取 2 个 JSON 差异的最佳方法的意见。如果有人有相同的示例代码，那就太好了。谢谢。

JSON 库 Jossons & Josson 对两个数据集进行设置操作。

https://github.com/octomix/josson

反序列化

Jossons jossons = new Jossons();
jossons.putDataset("JSON1", Josson.fromJsonString(
    "{" +

左减右

JsonNode node = jossons.evaluateQuery("JSON1 <-< JSON2");
System.out.println(node.toPrettyString());

输出

{
  "members" : [ {
    "mail" : null,
    "roles" : [ {
      "id" : null,
      "name" : "Author"
    }, {
      "id" : null,
      "name" : "Commenter"
    } ],
    "dng_ID" : "[email protected]",
    "ad_ID" : "CN=aaaaaaaaaa"
  }, {
    "mail" : null,
    "roles" : [ {
      "id" : null,
      "name" : "Author"
    } ],
    "dng_ID" : "[email protected]",
    "ad_ID" : "CN=bbbbbbbbbbb"
  } ]
}
