添加权限控制

 

1.导入Secure module,该模块提供了一个controllers.Secure控制器。

 /conf/application.conf

# Import the secure module
module.secure=${play.path}/modules/secure

  

/conf/routes

# Import Secure routes
*       /                                       module:secure

  

2.在Post Comment User Tag控制器上添加标签

@With(Secure.class)public class Posts extends CRUD {    
}

 

启动Server,访问 localhost:9000/admin,如果页面报错(或编译失败),参考上一章添加CRUD模块

3.添加权限控制

创建权限控制器 /controllers/Security.java

import models.*;public class Security extends Secure.Security {    static boolean authenticate(String username, String password) {        return User.connect(username, password) != null;
   }
}

通过 localhost:9000/logout 退出登录,使用正确的用户名密码进行登录

 

4.添加登录页面

创建Admin Controller

@With(Secure.class)public class Admin extends Controller {
   @Before    static void setConnectedUser() {        if(Security.isConnected()) {
           User user = User.find("byEmail", Security.connected()).first();
           renderArgs.put("user", user.fullname);
       }
   }    
   public static void index() {
       render();
   }
}

 

添加路由

# Administration
GET       /admin/?                                 Admin.index
*         /admin                                   module:crud

  

修改main.html


  

添加/views/admin.html



   


       Administration
       
       #{get ‘moreStyles‘ /}
                       href="@{‘/public/stylesheets/main.css‘}" />
                       href="@{‘/public/images/favicon.png‘}" />
       
       
   
   
       
       
       
       

           #{doLayout /}
       

       
       
       
   

  

添加/views/Admin/index.html

#{extends ‘admin.html‘ /}

Welcome ${user}!

  

5.添加角色

Security控制器重写check方法

static boolean check(String profile) {    if("admin".equals(profile)) {        return User.find("byEmail", connected()).first().isAdmin;
   }    return false;
}

 

修改admin.html,显示用户是否有admin角色


   
   

           

  •            My posts
           

  •        #{secure.check ‘admin‘}
               

  •                Posts
               

  •            

  •                Tags
               

  •            

  •                Comments
               

  •            

  •                Users
               

  •        #{/secure.check}
       

   
   #{doLayout /}

  

在Post、Tag、User、Comment控制器上添加标签,只有admin role的User才能访问 http://localhost:9000/admin/{####}

@Check("admin")@With(Secure.class)public class Posts extends CRUD {
}

Java Platform Independence: Differences between OSJava Platform Independence: Differences between OSMay 16, 2025 am 12:18 AM

There are subtle differences in Java's performance on different operating systems. 1) The JVM implementations are different, such as HotSpot and OpenJDK, which affect performance and garbage collection. 2) The file system structure and path separator are different, so it needs to be processed using the Java standard library. 3) Differential implementation of network protocols affects network performance. 4) The appearance and behavior of GUI components vary on different systems. By using standard libraries and virtual machine testing, the impact of these differences can be reduced and Java programs can be ensured to run smoothly.
