Escape JSON string in Java
jackson, java, json
Solution
No additional dependencies needed: You're looking for `JsonStringEncoder#quoteAsString(String)`.
Click for JsonStringEncoder javadoc
Example:
import com.fasterxml.jackson.core.io.JsonStringEncoder;
JsonStringEncoder e = JsonStringEncoder.getInstance();
String commands = "ls -laF\\ndu -h";
String encCommands = new String(e.quoteAsString(commands));
String o = "{commands: \"" + encCommands + "\", id: 0, timeout: 0}"

Problem
I'm using Google's `com.google.api.client.json.GenericJson` and `com.fasterxml.jackson.core.JsonGenerator`. I would like to serialize JSON object and escape quotes and backslashes so that I can pass that string in Bash. And afterwards deserialize that string. `GenericJson.toString` produces simple JSON, but `\n` etc. are not escaped: ``` {commands=ls -laF\ndu -h, id=0, timeout=0} ``` is there a simple way how to get something like this: ``` "{commands=\"ls -laF\\ndu -h\", id=0, timeout=0}" ``` I don't want to reinvent the wheel, so I'd like to use Jackson or an existing API, if possible.
