org.springframework.http.converter.StringHttpMessageConverter
public class StringHttpMessageConverter
Implementation of HttpMessageConverter
that can read and write strings.
By default, this converter supports all media types (*/*
), and writes with a Content-Type
of text/plain
. This can be overridden by setting the supportedMediaTypes
property.
