In this chapter, we will visit important classes and interfaces which are useful for developing extensions and plugins around Guice. We will also explore these interfaces in terms of analyzing various kinds of bindings in guice-multibinder.
In this process, we will separate out MainModule from our application, and make it a part of a custom plugin that we are developing. This custom plugin would contain various examples related to SPI. This custom plugin is located at chapter_7/guice-analyst
as a maven project; and the sample project, which uses this plugin is located at chapter_7/flights-struts-jpa-ext
.
