spring boot 2.0.0 + shiro + redis實現前后端分離的項目

簡介

Apache Shiro是一個強大且易用的Java安全框架,執行身份驗證、授權、密碼學和會話管理。使用Shiro的易於理解的API,您可以快速、輕松地獲得任何應用程序,從最小的移動應用程序到最大的網絡和企業應用程序。

demo地址在最下方給出。

本文主要實現shiro的以下幾個功能：

       1.當用戶沒有登陸時只能訪問登錄接口，訪問其他接口會返回無效的授權碼

　　2.當用戶登陸成功后，只能訪問該用戶權限下的接口，其他接口會返回無權限訪問

　　3.一個用戶不能兩個人同時在線，后登錄的會自動踢出先登錄的用戶

本文使用框架如下：

核心框架：spring boot 2.0.0, spring
mvc框架：spring mvc
持久層框架：mybatis
數據庫連接池：alibaba druid
安全框架：apache shiro
緩存框架：redis
日志框架：logback
數據庫設計：

數據庫主要分為5個表，分別是：用戶表，角色表，權限表，角色權限表，用戶角色表

 

 

 

由於數據表結構我直接拷貝的以前的項目，所以上表中很多字段該文不會用到，各位請根據自己的實際情況修改。

自定義密碼校驗器

package com.alex.springboot.system.shiro;
 
import com.alex.springboot.utils.MD5Util;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authc.credential.SimpleCredentialsMatcher;
 
public class CredentialsMatcher extends SimpleCredentialsMatcher {
 
    @Override
    public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
        UsernamePasswordToken utoken = (UsernamePasswordToken) token;
        // 獲得用戶輸入的密碼:(可以采用加鹽(salt)的方式去檢驗)
        String inPassword = new String(utoken.getPassword());
        // 獲得數據庫中的密碼
        String dbPassword = (String) info.getCredentials();
        // 進行密碼的比對
        return this.equals(MD5Util.encrypt(inPassword), dbPassword);
    }
}

自定義session容器，用於實現前后端分離，前端請求接口時將Token放在請求Header中，即可獲取到用戶的session信息（建議前端是將Token放在Header中，而不是放到body請求參數中，這樣可以統一做封裝處理，下面的代碼中是獲取Header中或者body中Token，建議直接獲取Header中Token即可）

package com.alex.springboot.system.shiro;
 
import org.apache.commons.lang3.StringUtils;
