Both @Autowired and @Resource work equally well. But there is a conceptual difference or a difference in the meaning.@Resource means get me a known resource by name. The name is extracted from the name of the annotated setter or field, or it is taken from the name-Parameter.@Inject or ...
So, basically these are two quite distinct concepts. Unfortunately the Spring-Implementation of@Resourcehas a built-in fallback, which kicks in when resolution by-name fails. In this case, it falls back to the@Autowired-kind resolution by-type. While this fallback is convenient, IMHO it cause...

Affects: 5.0.10 Summary The JSR305 @CheckForNull annotation should be treated equivalently to the Spring @org.springframework.lang.Nullable annotation. It is supposed to have the same semantic meaning: users of a variable should be check...
可以看到,@Autowired 是 Spring的亲儿子,而@Resource是Spring对它定义的一种实现,它们的功能如此相似。那么为什么要支持了@Resource,又要自己搞个@Autowired呢?对此专门查了一下Spring2.5的官方文档,文档中有一段这么说到: However, Spring 2.5 dramatically changes the landscape. As described above, the autowiring...
