可以使用@javax.inject来代替@Autowired。注入如下

可以使用@javax.inject来代替@Autowired。注入如下:
import javax.inject.Inject;
public class SimpleMovieLister {
private MovieFinder movieFinder;
@Inject
public void setMovieFinder(MovieFinder movieFinder) {
this.movieFinder = movieFinder;
}
public void listMovies() {
this.movieFinder.findMovies(…);
}
}

与@Autowired一样，您可以在字段级别、方法级别和构造函数-参数级别使用@Inject。此外，您可以将注入点声明为提供者，从而允许按需访问范围较短的bean，或通过Provider.get()调用延迟访问其他bean。下面的例子是上一个例子的变体:
import javax.inject.Inject;
import javax.inject.Provider;
public class SimpleMovieLister {
private Provider movieFinder;
@Inject
public void setMovieFinder(Provider movieFinder) {
this.movieFinder = movieFinder;
}
public void listMovies() {
this.movieFinder.get().findMovies(…);
}
}

如果你想为应该注入的依赖项使用限定名，你应该使用@Named注释，如下面的例子所示:
import javax.inject.Inject;
import javax.inject.Named;
public class SimpleMovieLister {
private MovieFinder movieFinder;
@Inject
public void setMovieFinder(@Named(“main”) MovieFinder movieFinder) {
this.movieFinder = movieFinder;
}
}

public class SimpleMovieLister {
@Inject
public void setMovieFinder(Optional movieFinder) {
}
}

public class SimpleMovieLister {
@Inject
public void setMovieFinder(@Nullable MovieFinder movieFinder) {
}
}

import javax.inject.Inject;
import javax.inject.Named;
@Named(“movieListener”) // @ManagedBean(“movieListener”) could be used as well
public class SimpleMovieLister {
private MovieFinder movieFinder;
@Inject
public void setMovieFinder(MovieFinder movieFinder) {
this.movieFinder = movieFinder;
}
}

import javax.inject.Inject;
import javax.inject.Named;
@Named
public class SimpleMovieLister {
private MovieFinder movieFinder;
@Inject
public void setMovieFinder(MovieFinder movieFinder) {
this.movieFinder = movieFinder;
}
}
