spring除了@DateTimeFormat之外,还提供了一个@NumberFormat注解,作用也是用来数据输入时适配入参的数据格式

比如下面的salary字段,输入时就可以接受11,000,00这种类型的数字

public class Student {
    private String name;
    private Integer gender;
    @DateTimeFormat(pattern="yyyy-MM-dd")
    private Date birth;
    @NumberFormat(pattern="#,###")
    private Integer salary;
    

    public Student(String name, Integer gender, Date birth, Integer salary) {
        super();
        this.name = name;
        this.gender = gender;
        this.birth = birth;
        this.salary = salary;
    }
}
