com.tosan.tools.tostring.JsonToStringBuilderImpl Maven / Gradle / Ivy
Library provides interface for use in toString method and determine each field how should be
shown. also, you can choose from two implementations provided for simple and json formatting.
also, provides interface for use in aspect to log service call.
