GSON的自定义PrintFormatting

Question

我在印刷方面遇到了一些麻烦。在印刷方面，GSON有两种选择。

1. 漂亮印刷
2. 紧凑印刷

我打算使用修改后的漂亮打印形式，尽管JsonPrintFormatter是用来修改输出格式的类，尽管文档说。我在GSON存储库中找不到那个类！

对于为什么会这样，或者无论如何，我可以修改GSON印刷，有什么想法吗？除此之外，任何用于修改Java语言中JSON的间距或格式的库也会有所帮助。

漂亮的印刷品：

    {
  "classname": "something",
  "type": "object",
  "version": 1,
  "properties": [
    {
      "propertyname": "something1",
      "type": "String",
      "length": 255
    },
    {
      "propertyname": "something2",
      "type": "Date",
      "length": 10
    }
  ]
}

紧凑型印刷：

{"classname":"something","type":"object","version":1,"properties":[{"propertyname":"something1","type":"String","length":255},{"propertyname":"something2","type":"Date","length":10}]}

我的印刷风格：

{
  "classname": "something",
  "type": "object",
  "version": 1,
  "properties": [
    {"propertyname": "something1","type": "String","length": 255},
    {"propertyname": "something2","type": "Date","length": 10}
  ]
}

好吧，目前它只是在进行中，但是对于只使用一个数组的字符串来说，这应该是有用的。将研究如何使它更稳定和能够处理更复杂的结构。

  private static String reformat(String og){
    String reformattable = og;
    String[] parts = reformattable.split("\\[",2);
    String arrayPart = parts[1];
    String arrayOnly = arrayPart.split("]",2)[0];
    reformattable = arrayOnly.replaceAll("\\{\n","{");
    reformattable = reformattable.replaceAll("\",\n", "\\\",");
    reformattable = reformattable.replaceAll(" +"," ");
    reformattable = reformattable.replaceAll("\\{ ","   {");
    reformattable = reformattable.replaceAll("\n }","}");

    return og.replace(arrayOnly,reformattable);
} 

结果应该如下所示(至少对于我的简单类是这样的)：

{
 "classname": "test",
 "properties": [
   {"propertyname": "1", "length": 1},
   {"propertyname": "1", "length": 1}
 ]
}
