这里我有一个在setTimeout回调函数中调用自身的函数：
function myFunc(){
// ... I'm doing my jobs here...
setTimeout(function(){
myFunc() //self invoke
},1)
}
myFunc(); // start point
这段代码最终会发生堆栈溢出异常吗？ 提前谢谢。

没有。通过@Data
@NoArgsConstructor
@AllArgsConstructor
@Entity
public class Book {
@Id
@SequenceGenerator(name = "book_id_seq_gen", sequenceName = "book_id_seq", allocationSize = 1)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "book_id_seq_gen")
private long id;
private String name;
private int year;
@ManyToOne
private Writer writer;
private String description;
private int downloadNumber;
@ManyToMany
@JoinTable(name = "book_genre",
joinColumns = @JoinColumn(name = "book_id"),
inverseJoinColumns = @JoinColumn(name = "genre_id")
)
private Set<Genre> genres;
}
@Data
@NoArgsConstructor
@AllArgsConstructor
@Entity
public class Writer {
@Id
@SequenceGenerator(name = "writer_id_seq_gen", sequenceName = "writer_id_seq", allocationSize = 1)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "writer_id_seq_gen")
private long id;
@NotNull(message = "Name cannot be null")
@Length(min = 1, max = 100)
private String name;
@NotNull(message = "Surname cannot be null")
@Length(min = 1, max = 100)
private String surname;
private String description;
@OneToMany(mappedBy = "writer")
private List<Book> books;
}
排队的函数仅在主线程（或当前正在进行的任何线程）完成后运行 - 没有嵌套调用/嵌套环境可能导致您担心的溢出。如果您运行此代码段，则永远不会遇到错误，例如：
setTimeout
同样的事情适用于调用通过function myFunc(i) {
if (i % 1000 === 0) console.log(i);
setTimeout(function() {
myFunc(++i)
})
}
myFunc(0);递归调用自己的promises的函数 - 它非常安全。
