json差异比较

如何比较两个json的差异

代码实现

1. 导入依赖

 <dependency>
            <groupId>cn.xiaoandcai</groupId>
            <artifactId>json-diff</artifactId>
            <!-- 旧版本可能存在某些缺陷。版本请以maven仓库最版为准。 -->
            <version>4.1.3-RC1-RELEASE</version>
        </dependency>

        <!-- 选择json解析框架。fastjson, fastjson2,gson,jackson 之一 -->
        <dependency>
            <groupId>cn.xiaoandcai</groupId>
            <artifactId>json-diff-impl-fastjson</artifactId>
            <version>4.1.3-RC1-RELEASE</version>
        </dependency>

2. 用例实现

 @Test
    public void testJsonDiff() throws JSONException, JsonProcessingException {
        String json1 = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\",\"phone\":\"13800000000\",\"dog\":{\"age\":4,\"name\":\"mojo\",\"weight\":\"21.5\"}}";
        String json2 = "{\"name\":\"John\", \"age\":35, \"city\":\"Chicago\",\"qq\":\"123456789\",\"dog\":{\"name\":\"mojo\",\"age\":\"2\",\"color\":\"red\"}}";
        JsonComparedOption jsonComparedOption = new JsonComparedOption().setIgnoreOrder(true);
        JsonCompareResult jsonCompareResult = new DefaultJsonDifference()
                .option(jsonComparedOption)
                .detectDiff(json1, json2);

        List<Defects> defectsList = jsonCompareResult.getDefectsList();
        for (Defects d : defectsList) {
            Object actual = d.getActual();
            Object expect = d.getExpect();
            System.out.println("路径：" + d.getTravelPath().getAbstractTravelPath() + ",旧值：" + expect + ",新值:" + actual);
        }
    }

执行结果
