java - 如果输入不正确，不允许用户将数据保存在mysql数据库中

嗨，我正在Spring Roo做项目。我在哪里可以限制电话号码为10位数字？我已经在create.jspx和User_Roo_DbManaged.aj中设置了限制，但是它不起作用。
它接受字母和较短的输入。

最佳答案

首先，您不应修改任何.aj，因为Spring Roo下次运行它时将覆盖您的更改。要自定义字段，您必须将其声明移到相关的.java文件中（我们称其为推入式）。

为了设置字段验证，Roo使用JSR-303 specification作为实现，使用Hibernate validation。

因此，要对其进行存档，请尝试：


将phone声明推入User.java并添加javax.validation.constraints.Size批注：

public class User {

   @Column(name = "phone", length = 10, unique = true)
   @NotNull
   @Size(max=10,min=10)
   private String phone;
}

运行Spring Roo控制台。


之后，Roo将：


从phone删除User_Roo_DbManaged.aj定义
在User_Roo_bean.aj上创建getter和setter
更新与User相关的.jspx


请注意，@Column定义是指数据库声明。您应该使用javax.validation.constraints.*批注或创建自己的其他任何字段验证（here you have an example）

祝好运！
