How to extract the value of serialized JSON String out of the POST HttpRequest with spring Resttemplate

Question

I'm trying to send an object with a POST HttpRequest in restTemplate.

restTemplate.postForObject(urlPOST, "POST", Some.class, someObject);

For debugging purposes i would like to get the serialized JSON string from the object out of springs restTemplate.

Where and how can I get access the json string that is sent to the server?

Answer 1

You can set your breakpoint at the class

public abstract class AbstractHttpMessageConverter<T> implements HttpMessageConverter<T>

in the Method

public final void write(T t, MediaType contentType, HttpOutputMessage
 outputMessage)

to see what the converted string!
