如何将Java对象转换为JSON字符串? [英] How to convert Java Object to JSON string?

问题描述

您好，我正在尝试将Java对象转换为Json字符串，以便在我的视图中使用javascript函数.

Hello i'm trying to convert my Java Object to a Json string to use in my view with javascript functions.

我尝试使用Google的gson lib:

I tried to use Google's gson lib:

String myjson = "";
Gson gson = new Gson();
myjson = gson.toJson(myuser);//myuser is my java object

但是，当我调用myjson时，它由"""而不是字符"""组成，因此我无法在我的视图中使用它，这给我带来了麻烦.

However when i call myjson, it consists of '"' instead of the character '"' for this reason i can't able to use it in my view, it is creating me problems.

如何解决此问题，如何正确创建Json字符串?

How can I fix this, how can I create Json string properly?

渲染myjson时是否有可能犯错误?

Edit : Is there a chance of making a mistake while rendering the myjson?

Edit2:要在视图中达到myjson的结果，我正在做

To reach the result of myjson in view, i'm doing

render(myjson);

render(myjson);

在我的代码末尾.

Edit3:Play框架具有renderJSON()方法.但是我不能使用它，因为我不仅在渲染myjson和其他元素.

Play framework has a method of renderJSON(). However i can't use it since i'm rendering not only myjson and some other elements too.

推荐答案

请注意，&"是正确的" JSON，因此无论您是否不想在JSON中使用实体，JavaScript都可以正确地转义.您要禁用html格式/转义.

Note that "&quot" is "Proper" JSON, so your javascript can be escaped properly, anyways if you dont want to use entities in you JSON perhaps you want to disable html formatting/escaping.

尝试使用

Gson gson = new GsonBuilder().disableHtmlEscaping().create();

检查GSONBuilder对象文档 http://google-gson.googlecode.com/svn/trunk/gson/docs/javadocs/com/google/gson/GsonBuilder.html
