这是一json相关的工具包，不包含序列化及反序列化实现，你可以使用fastjson、jackson等库，目前实现常用的工具有：
- 格式化
String json = "{\"name\":\"mi米\",\"age\":30,\"weight\":100.1,\"Children\":[\"a\",\"b\",\"c\"],\"address\":{ \"city\":\"GuangZhou\",\"pro\":\"GuangDong\"}}";
String expect = "{\n" +
" \"name\": \"mi米\",\n" +
" \"age\": 30,\n" +
" \"weight\": 100.1,\n" +
" \"Children\": [\n" +
" \"a\",\n" +
" \"b\",\n" +
" \"c\"\n" +
" ],\n" +
" \"address\": {\n" +
" \"city\": \"GuangZhou\",\n" +
" \"pro\": \"GuangDong\"\n" +
" }\n" +
"}";
Assert.assertEquals(expect, JsonUtils.format(json));- 属性过滤
String json = "{\"name\":\"mi米\",\"age\":30,\"weight\":100.1,\"Children\":[\"a\",\"b\",\"c\"],\"address\":{ \"city\":\"GuangZhou\",\"pro\":\"GuangDong\"}}";
Assert.assertEquals("{\"name\":\"mi米\",\"weight\":100.1,\"address\":{ \"city\":\"GuangZhou\" }",
JsonUtils.removeProperty(json, new String[]{"name", "weight", "address.city"}, true));
