HashMap到带有嵌套对象的json字符串

Question

是否有任何库可根据地图中的点值将HashMap转换为带有嵌套对象的json字符串？

Java：

HashMap<String, String> params = new HashMap<>();
params.put("field_1", "value_1");
params.put("object_1.field_1", "value_1");
params.put("object_1.field_2", "value_2");
params.put("object_2.field_5", "value_5");
params.put("object_2.field_6", "value_6");

应转换为字符串：

{
    "field_1": "value_1",
    "object_1": {
        "field_1": "value_1",
        "field_2": "value_2"
    },
    "object_2": {
        "field_5": "value_5",
        "field_6": "value_6"
    }
}

我找到了可以做到的图书馆

    <dependency>
        <groupId>pl.jalokim.propertiestojson</groupId>
        <artifactId>java-properties-to-json</artifactId>
        <version>5.0.0</version>
    </dependency>

就那么简单：

new PropertiesToJsonConverter().convertToJson(params)
