Is there a method to transform a Java object into a string with the following criteria? It is important that all field names are properly escaped, and the records are separated by "\n".
{
"content":"{\"field1\":123, \"field2\":1, \"field3\":0, \"field4\":{\"sub1\":\"abc\", \"sub2\":\"xyz\"}}\n
{\"field1\":234, \"field2\":9, \"field3\":1, \"field4\":{\"sub1\":\"xyz\", \"sub2\":\"abc\"}}"
}
Your assistance would be highly appreciated.
If you want to accomplish that task, consider utilizing the GSON library.
Gson is an excellent Java library that specializes in converting Java Objects into their JSON representation. It also facilitates converting a JSON string back into its equivalent Java object. Gson has the ability to handle any type of Java object, even if you don't possess the source code for it.
For a more visually appealing output, you can make use of the pretty-print feature.
A neat way to enable this is by using the following code snippet: Gson gson = new GsonBuilder().setPrettyPrinting().create();In order to achieve something similar to your example, firstly serialize your content class, then embed the resulting string as a property within another class and serialize that one again.
This method ensures that GSON takes care of escaping special characters like double quotes (").
If you gather your strings in an array and apply the aforementioned pretty print option, you will obtain a result that shares similarities with your requirement regarding line breaks, although not identical.
The outcome of the above-mentioned process might appear as follows:
{
"content": [
"{\"field1\":123, \"field2\":1, \"field3\":0, \"field4\":{\"sub1\":\"abc\", \"sub2\":\"xyz\"}}",
"{\"field1\":234, \"field2\":9, \"field3\":1, \"field4\":{\"sub1\":\"xyz\", \"sub2\":\"abc\"}}"
]
}
One possible solution is to incorporate the Json-lib library into your project, which can be found at this link.
In order to utilize this library, you will need to define a string variable called jsonStrData and assign it a value. Afterwards, create a JSONObject object named jsonObj using the fromObject method with jsonStrData as its parameter. Finally, print out the contents of jsonObj by invoking System.out.println(jsonObj).Similar to GSON, json-lib takes care of escaping characters for you. For more detailed instructions on how to use json-lib, refer to this page.
