有任何主要的JSON库支持这一点吗?org。Json库只是做一个引用比较。

但org。Json支持这个!使用similar()代替equals()。

我正在使用这个，并为我工作良好(org.json.*):

package com.project1.helpers;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import java.util.HashMap;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;

public class JSONUtils {

    public static boolean areEqual(Object ob1, Object ob2) throws JSONException {
        Object obj1Converted = convertJsonElement(ob1);
        Object obj2Converted = convertJsonElement(ob2);
        return obj1Converted.equals(obj2Converted);
    }

    private static Object convertJsonElement(Object elem) throws JSONException {
        if (elem instanceof JSONObject) {
            JSONObject obj = (JSONObject) elem;
            Iterator<String> keys = obj.keys();
            Map<String, Object> jsonMap = new HashMap<>();
            while (keys.hasNext()) {
                String key = keys.next();
                jsonMap.put(key, convertJsonElement(obj.get(key)));
            }
            return jsonMap;
        } else if (elem instanceof JSONArray) {
            JSONArray arr = (JSONArray) elem;
            Set<Object> jsonSet = new HashSet<>();
            for (int i = 0; i < arr.length(); i++) {
                jsonSet.add(convertJsonElement(arr.get(i)));
            }
            return jsonSet;
        } else {
            return elem;
        }
    }
}

你可以尝试使用json-lib的JSONAssert类:

JSONAssert.assertEquals(
  "{foo: 'bar', baz: 'qux'}",
  JSONObject.fromObject("{foo: 'bar', baz: 'xyzzy'}")
);

给:

junit.framework.ComparisonFailure: objects differed at key [baz]; expected:<[qux]> but was:<[xyzzy]>

空手道正是你要找的。这里有一个例子:

* def myJson = { foo: 'world', hey: 'ho', zee: [5], cat: { name: 'Billie' } }
* match myJson = { cat: { name: 'Billie' }, hey: 'ho', foo: 'world', zee: [5] }
