how to print Original request body JSON without any modification in java?
问题
通常我使用ObjectMapper来打印请求体，但这种方式会移除空格并将对象一行打印成字符串，示例：
如果我发送这样的请求体：
{
"Header" : "value"
}
然后我使用objectMapper来打印那个对象：
ObjectMapper mapper = new ObjectMapper();
mapper.writeValueAsString(requestBody)
输出会是这样的：
{"Header":"value"}
如何打印原始请求体而没有任何修改？
英文:
Normally to print out request body i using ObjectMapper, but this way removing space and printing object to string in one line, example :
if i send request body like this :
{
"Header" : "value"
}
and i using objectMapper to print that object
ObjectMapper mapper = new ObjectMapper();
mapper.writeValueAsString(requestBody)
the out put is like this :
{"Header":"value"}

我不确定您是否可以将其以原始形式打印出来，但您可以进行漂亮的打印。
使用Jackson的对象映射器，您可以像这样操作：
ObjectMapper mapper = new ObjectMapper();
String json = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(body);
System.out.println(json);
或者
ObjectMapper mapper = new ObjectMapper().enable(SerializationFeature.INDENT_OUTPUT);
String json = mapper.writeValueAsString(body);
System.out.println(json);
英文:
I'm not sure if you can print it in it's original form but you can pretty print it.
With Jackson's Object Mapper, you can do something like:
ObjectMapper mapper = new ObjectMapper();
String json = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(body);
System.out.println(json);
or
ObjectMapper mapper = new ObjectMapper().enable(SerializationFeature.INDENT_OUTPUT);
String json = mapper.writeValueAsString(body);
System.out.println(json);

我认为你无法在不使用任何框架的情况下完成这个任务。
但是，如果你启用了prettyPrinting选项，你可以使用Gson来实现。示例代码如下：
Gson gson = new GsonBuilder()
.setPrettyPrinting()
.create();
prettyPrintedString = gson.toJson(requestBody, Object.class);
英文:
I don't think you can do this without using any framework.
But you can use the gson for this if you enable the prettyPrinting option. Example:
Gson gson = new GsonBuilder()
.setPrettyPrinting()
.create();
prettyPrintedString = gson.toJson(requestBody, Object.class);
