来自 Jackson 2.2 的 ObjectMapper 的漂亮打印 JSON [英] Pretty printing JSON from Jackson 2.2's ObjectMapper
问题描述
现在我有一个 org.fasterxml.jackson.databind.ObjectMapper
的实例,并想获得一个带有漂亮 JSON 的 String
.我的谷歌搜索的所有结果都提出了 Jackson 1.x 的方法,我似乎无法找到使用 2.2 执行此操作的正确的、未弃用的方法.尽管我不认为代码对于这个问题是绝对必要的,但我现在拥有的是:
Right now I have an instance of org.fasterxml.jackson.databind.ObjectMapper
and would like to get a String
with pretty JSON. All of the results of my Google searches have come up with Jackson 1.x ways of doing this and I can't seem to find the proper, non-deprecated way of doing this with 2.2. Even though I don't believe that code is absolutely necessary for this question, here's what I have right now:
ObjectMapper mapper = new ObjectMapper();
mapper.setSerializationInclusion(Include.NON_NULL);
System.out.println("
----------REQUEST-----------");
StringWriter sw = new StringWriter();
mapper.writeValue(sw, jsonObject);
// Want pretty version of sw.toString() here
推荐答案
您可以通过在 ObjectMapper
上设置 SerializationFeature.INDENT_OUTPUT
来启用漂亮打印,如下所示:
You can enable pretty-printing by setting the SerializationFeature.INDENT_OUTPUT
on your ObjectMapper
like so:
mapper.enable(SerializationFeature.INDENT_OUTPUT);
