Question

我已经使用gson的JsonWriter编写了一个程序来创建一个json文件，创建json文件效果很好但它给了我格式化的json不是最好的看到我希望能够手工编辑这个文件

示例：程序给了我

{"bells":{"category":"hostile","sounds":["bells"]},"ankylosaurus":{"category":"hostile","sounds":["dinosaurs/ankylosaurus/AnkylosaurusCall1","dinosaurs/ankylosaurus/AnkylosaurusCall2","dinosaurs/ankylosaurus/AnkylosaurusRoar1","dinosaurs/ankylosaurus/AnkylosaurusRoar2","dinosaurs/ankylosaurus/AnkylosaurusSay1","dinosaurs/ankylosaurus/AnkylosaurusSay2"]},...

但我想将其导出为

{
"bells":{
    "category":"hostile",
    "sounds":[
        "bells"
    ]
},
"ankylosaurus":{
    "category":"hostile",
    "sounds":[
        "dinosaurs/ankylosaurus/AnkylosaurusCall1",
        "dinosaurs/ankylosaurus/AnkylosaurusCall2",
        "dinosaurs/ankylosaurus/AnkylosaurusRoar1",
        "dinosaurs/ankylosaurus/AnkylosaurusRoar2",
        "dinosaurs/ankylosaurus/AnkylosaurusSay1",
        "dinosaurs/ankylosaurus/AnkylosaurusSay2"
    ]
},
...

Answer 1

Gson比JsonWriter更通用，并且具有“漂亮打印”选项。

您可以使用它来写入这样的流：

private Gson gson = new GsonBuilder()
    .setPrettyPrinting()
    .create();

OutputStreamWriter writer = ...
writer.write(gson.toJson(object));

Answer 2

是的！启用漂亮打印：）

Gson gson = new GsonBuilder().setPrettyPrinting().create();
String json = gson.toJson(yourDataHere);

Answer 3

如果您想继续使用JsonWriter，specify an indent可以实现您的目标：

jsonWriter.setIndent("    ");

我可以将gson JsonWriter格式化为可读的东西吗？
