Can you avoid Gson converting "<" and ">" into unicode escape sequences?
提问by Jonik
I noticed that Gsonconverts the string "<" into an unicode escape sequence in JSON output. Can you avoid this somehow, or do characters like "<" and ">" always have to be escaped in JSON?
我注意到Gson将字符串“<”转换为 JSON 输出中的 unicode 转义序列。你能以某种方式避免这种情况吗，或者像“<”和“>”这样的字符总是必须在 JSON 中转义？
Consider this example which prints {"s":"\u003c"}; I'd want simply {"s":"<"}.
考虑这个打印的例子{"s":"\u003c"}；我只想 {"s":"<"}.
public static void main(String[] args) {
Gson gson = new GsonBuilder().create();
System.out.println(gson.toJson(new Foo()));
}
static class Foo {
String s = "<";
}
Context: the piece of JSON I'm creating has nothing to do with HTML pages or even JavaScript; it's just used to pass certain structured information to another piece of software (embedded in a device, written in C).
上下文：我创建的 JSON 片段与 HTML 页面甚至 JavaScript 无关；它只是用来将某些结构化信息传递给另一个软件（嵌入在设备中，用 C 编写）。

You need to disable HTML escaping.
您需要禁用 HTML 转义。
Gson gson = new GsonBuilder().disableHtmlEscaping().create();
