java - 使用 boolean 值设置实体的字符串字段？

以下是名为Person的Entity：

@Entity
@Table(
    name = "PERSON"
)
public class Person {

    //other fields etc

    @Column(
        name = "PAID_IN_FULL",
        nullable = false
    )
    private String paidInFull;

   public void setPaidInFull(boolean paidInFull) {
        this.paidInFull = paidInFull?"Y":"N";
    }

}

如果要执行以下操作，请使用上面的设置器：

person.setPaidInFull(true);

将其设置为什么字符串值，它是"Y"还是"N"？

最佳答案

paidInFull?"Y":"N";

如果说：

if (paidInFull)
    return "Y";
else
    return "N";

所以如果你要做

person.setPaidInFull(true);

this.paidInFull将为“ Y”。

这是一个完整的示例：

package nl.testing.startingpoint;

public class Main {
    private static String paidInFull;

    public static void main(String args[])
    {
        setPaidInFull(true);
        System.out.println(paidInFull);
    }

    public static void setPaidInFull(boolean paidInFull) {
        Main.paidInFull = (paidInFull) ? "Y" : "N";
    }
}
