java - How can a JSR 330 dependency injector verify dependencies at build time? -

-

i looking @ jsr 330 (javax.inject) javadoc , confused following sentence:

moreover, injector can verify dependencies have been satisfied @ build time.

how possible?* implementations support this?

*i guessing there must code generation involved, how code know being compiled in order generate code necessary statically verify dependencies met?

spring framework support jsr-330 , can configured weaving @ compile time using aspectj compiler, means classes modified @ byte-code introduce dependency injection during compile phase. fault spring performs weaving @ runtime. see does spring aop compile time weaving or load time weaving?
