1.开启CRUD Module
在/conf/application.conf 中添加
# import the crud module
module.crud=${play.path}/modules/crud
在/conf/routes 中添加
# import CRUD routes
* /admin module:crud
需要重启Server，导入CRUD Module
2.添加控制器
/app/controllers
import play.*;import play.mvc.*;
public class Posts extends CRUD {
}public class Tags extends CRUD {
}public class Users extends CRUD {
}public class Comments extends CRUD {
}
可能会提示错误： CRUD 无法解析为类型 并且运行程序会提示错误
解决办法：
修改 conf/dependencies.yml
require:
- play
- play -> crud
运行Shell
> play dependencies
工程下会生成 modules/crud 文件，重新启动工程即可，但是编译还是会出错，可能是没有引用crud工程的原因
3.创建Controller
package controllers;import models.User;@CRUD.For(User.class)public class AdminUsers extends CRUD {}
4.修改Model，添加验证
以User为例
public class User extends Model {
@Email
@Required public String email; @Required
@PassWord
public String password; public String fullname; public String isAdmin; public String toString() { return email;
}
}
进入http://localhost:9000/admin/ 选择add user进入 User Form进行测试
public class Post extends Model {
@Required public String title; @Required public Date postedAt; @Lob
@Required
@MaxSize(10000) public String content; @Required
@ManyToOne public User author; @oneToMany(mappedBy = "post", cascade = CascadeType.ALL) public List
}
public class Tag extends Model implements Comparable
@Required public String name;
}
public class Comment extends Model {
@Required public String author;
@Required public Date postedAt; @Lob
@Required
@MaxSize(10000) public String content; @ManyToOne
@Required public Post post;
}
5.页面上显示的Label名字是小写，与对应类的字段名一致，如果想显示大写，可以修改/conf/messages
title=Title
content=Content
postedAt=Posted at
author=Author
post=Related post
tags=Tags set
name=Common name
email=Email
password=Password
fullname=Full name
isAdmin=User is admin
