shiro

apache shiro 是一個輕量級的身份驗證與授權框架，與spring security 相比較，簡單易用，靈活性高，springboot本身是提供了對security的支援，畢竟是自家的東西。springboot暫時沒有整合shiro，這得自己配。

shiro 內建過濾器

本文實現：

本文實現從資料庫讀取使用者資訊，獲取當前使用者的許可權或角色，通過配置檔案過濾使用者的角色或許可權。擁有相應的角色或者相應的許可權的使用者可以訪問相應的url。

資料庫設計

1. 新增依賴

  <dependency>
            <groupId
 
>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.2.5</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-ehcache</artifactId
 
>
            <version>1.2.5</version>
        </dependency>
        <dependency>
            <groupId>com.github.theborakompanioni</groupId>
            <artifactId>thymeleaf-extras-shiro</artifactId>
            <version>1.2.1</version>
        </dependency
 
>

2. 新增shiro 配置

package com.us.shiro;

//    public EhCacheManager ehCacheManager() {
//        return new EhCacheManager();
//    }

    /**
     * SecurityManager，許可權管理，這個類組合了登陸，登出，許可權，session的處理，是個比較重要的類。
//     */
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();

        shiroFilterFactoryBean.setSecurityManager(securityManager());

        Map<String, Filter> filters = new LinkedHashMap<>();
        LogoutFilter logoutFilter = new LogoutFilter();
        logoutFilter.setRedirectUrl("/login");
//        filters.put("logout",null);
        shiroFilterFactoryBean.setFilters(filters);

        //        filterChainDefinitionManager.put("/user/edit/**", "authc,perms[user:edit]");// 這裡為了測試，固定寫死的值，也可以從資料庫或其他配置中讀取，此處是用許可權控制

    }


}

3. 新增Realm 驗證

package com.us.shiro;

import com.us.bean.Permission;
import com.us.bean.Role;
import com.us.bean.User;
import com.us.dao.PermissionDao;
import com.us.dao.UserDao;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.PrincipalCollection;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;

/**
 * Created by cdyoue on 2016/10/21.
 */

public class ShiroRealm extends AuthorizingRealm {
    private Logger logger =  LoggerFactory.getLogger(this.getClass());

    @Autowired
    private UserDao userService;
    @Autowired
    private PermissionDao permissionService;
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        logger.info("doGetAuthorizationInfo+"+principalCollection.toString());
        User user = userService.getByUserName((String) principalCollection.getPrimaryPrincipal());


        //把principals放session中 key=userId value=principals
        SecurityUtils.getSubject().getSession().setAttribute(String.valueOf(user.getId()),SecurityUtils.getSubject().getPrincipals());

        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        //賦予角色
        for(Role userRole:user.getRoles()){
            info.addRole(userRole.getName());
        }
        //賦予許可權
        for(Permission permission:permissionService.getByUserId(user.getId())){
//            if(StringUtils.isNotBlank(permission.getPermCode()))
                info.addStringPermission(permission.getName());
        }

        //設定登入次數、時間
//        userService.updateUserLogin(user);
        return info;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        logger.info("doGetAuthenticationInfo +"  + authenticationToken.toString());

        UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
        String userName=token.getUsername();
        logger.info(userName+token.getPassword());

        User user = userService.getByUserName(token.getUsername());
        if (user != null) {
//            byte[] salt = Encodes.decodeHex(user.getSalt());
//            ShiroUser shiroUser=new ShiroUser(user.getId(), user.getLoginName(), user.getName());
            //設定使用者session
            Session session = SecurityUtils.getSubject().getSession();
            session.setAttribute("user", user);
            return new SimpleAuthenticationInfo(userName,user.getPassword(),getName());
        } else {
            return null;
        }
//        return null;
    }

}

4. 新增controller

package com.us.controller;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;

import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import org.springframework.web.bind.annotation.*;

import java.util.HashMap;
import java.util.Map;

/**
 * Created by cdyoue on 2016/10/21.
 * 登陸控制器
 */
@RestController
public class LoginController {
    private Logger logger = LoggerFactory.getLogger(this.getClass());

    @RequestMapping(value = "/login", method = RequestMethod.POST)
    public String login(
            @RequestParam(value = "username", required = true) String userName,
            @RequestParam(value = "password", required = true) String password,
            @RequestParam(value = "rememberMe", required = true, defaultValue = "false") boolean rememberMe
    ) {
        logger.info("==========" + userName + password + rememberMe);
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(userName, password);
        token.setRememberMe(rememberMe);

        try {
            subject.login(token);
        } catch (AuthenticationException e) {
            e.printStackTrace();
//            rediect.addFlashAttribute("errorText", "您的賬號或密碼輸入錯誤!");
            return "{\"Msg\":\"您的賬號或密碼輸入錯誤\",\"state\":\"failed\"}";
        }
        return "{\"Msg\":\"登陸成功\",\"state\":\"success\"}";
    }

    @RequestMapping("/")
    @ResponseBody
    public String index() {
        return "no permission";
    }
}

此處程式碼不全，只是寫了springboot 整合的主要類，如果需要全部程式碼請移步。。。
