Can @Inject be made optional in JSR 330 (like @Autowire(required=false)?

Spring's @Autowire can be configured such that Spring will not throw an error if no matching autowire candidates are found: @Autowire(required=false)

Is there an equivalent JSR-330 annotation? @Inject always fails if there is no matching candidate. Is there any way I can use @Inject but not have the framework fail if no matching types are found? I haven't been able to find any documentation to that extent.

Solution

  • No... there is no equivalent for optional in JSR 330... if you want to use optional injection then you will have to stick with the framework specific @Autowired annotation
