With great power comes great responsibility. I've seen Spring projects where DI was a total rat nest of hundreds of XML wireup config files. Downhill with a tailwind, it just might boot correctly, after minutes classpath scanning for dependencies. Use DI judiciously where it provides the most value. Type, if you can type it (e.g. I vastly prefer explicit wireup in Guice Module.java files over Spring's "stringly typed" XML files. Type checking is more likely to catch classpath errors and typos. Event better, use compile time macro wireup like Scala's Macwire.
