Java 记录验证注解

Question

我有带有有效注释的旧 POJO:

public class SomeData {

    @NotNull(message = "Data not be null")
    private String data;

    public FormData(String data) {
        this.data = data;
    }

    public String getData() {
        return data;
    }

   public String setData(String data) {
        this.data = data
    }
    
}

但知道我有记录

public record SomeData(String data) {}

如何在记录中添加注释？

Answer 1

你可以这样做:

public record SomeData(@NotNull(message = "Data not be null") String data) {}
