这可能会帮助那些使用Spring Framework的人。你可以重用内部使用的在ResultActions上做断言(用于控制器测试):

进口:org.springframework.test.util.JsonExpectationsHelper

你可以编写带有详细输出的测试:

java.lang.AssertionError: someObject.someArray[1].someInternalObject2.value
Expected: 456
     got: 4567

测试代码:

@Test
void test() throws Exception {

    final String json1 =
        "{" +
        "  'someObject': {" +
        "    'someArray': [" +
        "      {" +
        "        'someInternalObject': {" +
        "          'value': '123'" +
        "        }" +
        "      }," +
        "      {" +
        "        'someInternalObject2': {" +
        "          'value': '456'" +
        "        }" +
        "      }" +
        "    ]" +
        "  }" +
        "}";

    final String json2 =
        "{" +
        "  'someObject': {" +
        "    'someArray': [" +
        "      {" +
        "        'someInternalObject': {" +
        "          'value': '123'" +
        "        }" +
        "      }," +
        "      {" +
        "        'someInternalObject2': {" +
        "          'value': '4567'" +
        "        }" +
        "      }" +
        "    ]" +
        "  }" +
        "}";

    new JsonExpectationsHelper().assertJsonEqual(json1, json2, true);
}

下面是使用Jackson ObjectMapper的代码。要了解更多，请阅读这篇文章。

import com.fasterxml.jackson.*

boolean compareJsonPojo(Object pojo1, Object pojo2) {
        try {
            ObjectMapper mapper = new ObjectMapper();
            String str1 = mapper.writeValueAsString(pojo1);
            String str2 = mapper.writeValueAsString(pojo2);
            return mapper.readTree(str1).equals(mapper.readTree(str2));
        } catch (JsonProcessingException e) {
            throw new AssertionError("Error comparing JSON objects: " + e.getMessage());
        }
    }

使用这个库:https://github.com/lukas-krecan/JsonUnit

Pom:

<dependency>
    <groupId>net.javacrumbs.json-unit</groupId>
    <artifactId>json-unit-assertj</artifactId>
    <version>2.24.0</version>
    <scope>test</scope>
</dependency>

IGNORING_ARRAY_ORDER -忽略数组中的顺序

assertThatJson("{\"test\":[1,2,3]}")
  .when(Option.IGNORING_ARRAY_ORDER)
  .isEqualTo("{\"test\": [3,2,1]}");

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]>

        "    ]" +
        "  }" +
        "}";

    new JsonExpectationsHelper().assertJsonEqual(json1, json2, true);
}

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] }
