关于Gson解析时候特殊符号，被转义的问题，如 单引号

Posted 2021-02-07 skinchqqhah

//Creating the JSON object, and getting as String:
JsonObject json = new JsonObject();
JsonObject inner = new JsonObject();
inner.addProperty("value", "xpath(‘hello‘)");
json.add("root", inner);
System.out.println(json.toString());

//Trying to pretify JSON String:
Gson gson = new GsonBuilder().setPrettyPrinting().create();
JsonParser parser = new JsonParser();
JsonElement je = parser.parse(json.toString());
System.out.println(gson.toJson(je));

输出

{"root":{"value":"xpath(‘hello‘)"}}
{
  "root": {
    "value": "xpath(u0027hellou0027)"
  }
}


解决办法

Gson gs = new GsonBuilder()
    .setPrettyPrinting()
    .disablehtmlEscaping()
    .create();
