How to serialize all int and boolean field to String with Jackson Json lib

I'm working on aria2 jsonrpc remote revoke, and I found out that all aria2 accept are strings value, like number 1 should be "1".

Although I can use JsonSerializer Annotation or use Module method, I think there should be an easy way which could apply "Int to String Serializer" to all of the fields of type int.

Could anyone give me a hint how to do this?

Finally, I found an article that has described three steps to do that, and I thought that may be a through answer:

  • Create a custom serializer extending the StdSerializer class

  • Create an object of SimpleModule class, adding to it the custom serializer and specifying for which class it must be used

  • Register the module on the ObjectMapper instance

ref: Jackson: create and register a custom JSON serializer with StdSerializer and SimpleModule classes
