playframework - 在play 2.3.3中，实体一定要get set？

Question

在游戏 2.1.1 中，实体 Login.java:

public class Login {
    @NotBlank(message = "login account cannot be empty")
    public String mobile;
    @NotBlank(message = "login password cannot be empty")
    public String password;
    public Integer ownInnId;
    public InnAdmin admin;
    public String token;
}

但在玩 2.3.3 时，发帖有错误:

在游戏2.3.3中，实体必须设置好吗？

Answer 1

Play 不会强制您定义 getter/setter。您可以声明和使用它们，也可以直接访问公共(public)字段。

在后台，Ebean 仍会在编译后创建 getter/setter，因此您将无法在代码中使用它们。

关于您的错误，请尝试清理您的项目，然后重新编译:

$ play clean-all
$ play compile
