SpringMVC+Shiro權限管理

什麼是權限呢？舉個簡單的例子：

我有一個論壇，註冊的用戶分爲normal用戶，manager用戶。
對論壇的帖子的操作有這些：
添加，刪除，更新，查看，回覆
我們規定：
normal用戶只能：添加，查看，回覆
manager用戶可以：刪除，更新

normal，manager對應的是角色（role）
添加，刪除，更新等對應的是權限（permission）

我們採用下面的邏輯創建權限表結構（不是絕對的，根據需要修改）

一個用戶可以有多種角色（normal,manager,admin等等）
一個角色可以有多個用戶（user1,user2,user3等等）
一個角色可以有多個權限（save,update,delete,query等等）
一個權限只屬於一個角色（delete只屬於manager角色）

我們創建四張表：
t_user用戶表:設置了3個用戶
-------------------------------
id + username   + password
---+----------------+----------
1  +   tom +  000000
2  +   jack +  000000
3  +   rose +  000000
---------------------------------
t_role角色表：設置3個角色
--------------
id + rolename
---+----------
1  + admin
2  + manager
3  + normal
--------------
t_user_role用戶角色表：tom是admin和normal角色，jack是manager和normal角色，rose是normal角色
---------------------
user_id  +  role_id
-----------+-----------
1 + 1
1 + 3
2 + 2
2 + 3
3 + 3
---------------------
t_permission權限表：admin角色可以刪除，manager角色可以添加和更新，normal角色可以查看
-----------------------------------
id  +  permissionname  +  role_id
----+------------------------+-----------
1   +   add + 2
2   +   del + 1
3   +   update + 2
4   +   query + 3

-----------------------------------

建立對應的POJO：

1，導入jar
2，配置web.xml
3，建立dbRelm
4，在Spring中配置

用於登錄，登出，權限跳轉的控制：

package com.cn.controller;  
  
import javax.validation.Valid;  
  
import org.apache.shiro.SecurityUtils;  
import org.apache.shiro.authc.AuthenticationException;  
import org.apache.shiro.authc.UsernamePasswordToken;  
import org.springframework.stereotype.Controller;  
import org.springframework.ui.Model;  
import org.springframework.validation.BindingResult;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.bind.annotation.RequestMethod;  
import org.springframework.web.servlet.mvc.support.RedirectAttributes;  
  
import com.cn.pojo.User;  
  
@Controller  
public class HomeController {  
  
    @RequestMapping(value="/login",method=RequestMethod.GET)  
    public String loginForm(Model model){  
        model.addAttribute("user", new User());  
        return "/login";  
    }  
      
    @RequestMapping(value="/login",method=RequestMethod.POST)  
    public String login(@Valid User user,BindingResult bindingResult,RedirectAttributes redirectAttributes){  
        try {  
            if(bindingResult.hasErrors()){  
                return "/login";  
            }  
            //使用權限工具進行用戶登錄，登錄成功後跳到shiro配置的successUrl中，與下面的return沒什麼關係！  
            SecurityUtils.getSubject().login(new UsernamePasswordToken(user.getUsername(), user.getPassword()));  
            return "redirect:/user";  
        } catch (AuthenticationException e) {  
            redirectAttributes.addFlashAttribute("message","用戶名或密碼錯誤");  
            return "redirect:/login";  
        }  
    }  
      
    @RequestMapping(value="/logout",method=RequestMethod.GET)    
    public String logout(RedirectAttributes redirectAttributes ){   
        //使用權限管理工具進行用戶的退出，跳出登錄，給出提示信息  
        SecurityUtils.getSubject().logout();    
        redirectAttributes.addFlashAttribute("message", "您已安全退出");    
        return "redirect:/login";  
    }   
      
    @RequestMapping("/403")  
    public String unauthorizedRole(){  
        return "/403";  
    }  
}
