@Value 注释在 Spring 的构造函数依赖注入中是什么意思？

Question

我有一个看起来像这样的片段

@Component
public class Inspiration {
        private String lyric =
            "I can keep the door cracked open, to let light through";
        public Inspiration(
            @Value("For all my running, I can understand") String lyric) {
            this.lyric = lyric;
        }
        public String getLyric() {
            return lyric;
        }
        public void setLyric(String lyric) {
            this.lyric = lyric;
        }
}

@Value("For all my running, I can understand")这里是什么意思，代表参数lyric的默认值吗？
