GSON issue with String
提问by Fahad Ishaque
String s = "m\"+"/m\/m/m/m/m/m";
LinkedHashMap<String, String> hm = new LinkedHashMap<>();
hm.put("test", s);
System.out.println(hm+" Hash map = "+hm.toString());
Fine Output is {test=m\/m\/m/m/m/m/m} Hash map = {test=m\/m\/m/m/m/m/m}
精细输出是 {test=m\/m\/m/m/m/m/m} Hash map = {test=m\/m\/m/m/m/m/m}
String s2 = new Gson().toJson(hm.toString());
System.out.println("Json result is "+s2);
Not FineOutput is Json result is "{test\u003dm\\/m\\/m/m/m/m/m}"
Not Fine输出是Json result is "{test\u003dm\\/m\\/m/m/m/m/m}"
Is GSONgoing mad or is it something that I am doing wrong? What is happening to with Back Slashesand from where does this u003dappears? I knew that there exists a bug of this nature a long time ago but it was resolved.
How can I resolve this issue?
Thanks in advance.
是GSON要疯了或者是它的东西，我做错了什么？反斜杠发生了什么，它从哪里u003d出现？我很久以前就知道存在这种性质的错误，但已解决。我该如何解决这个问题？提前致谢。

The =sign is encoded to \u003d.Hence you need to use disableHtmlEscaping().
该=标志编码为\u003d.因此你需要使用disableHtmlEscaping（） 。
You can use
您可以使用
Gson gson = new GsonBuilder().disableHtmlEscaping().create();
String s2 = gson.toJson(hm.toString());
For \/turning into \\/issue, the solution is
对于\/变成\\/问题，解决方案是
s2.replace("\\", "\");

@Bajrang Hudda has asked about \n ... I hit this issue recently ... I was able to solve it using:
@Bajrang Hudda 询问了 \n ......我最近遇到了这个问题......我能够使用以下方法解决它：
