3-8 基于SpringBoot连接数据库与配置MyBatis实操创建表sql

發(fā)布時間：2023/12/3 javascript 23 豆豆

生活随笔收集整理的這篇文章主要介紹了 3-8 基于SpringBoot连接数据库与配置MyBatis实操创建表sql 小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

11? ? ? ? ? ? ? ? ? ? 13-8 基于SpringBoot連接數(shù)據(jù)庫與配置MyBatis實(shí)操

springSecurity提供了? ? ?現(xiàn)成的基于內(nèi)存管理的類? ? ?

shiro則必須自己設(shè)計這樣的類? ? ? 需要自己設(shè)計用戶權(quán)限這樣的體系

這里基于RBAC簡單的設(shè)計一套

-- 權(quán)限表 -- CREATE TABLE permission (pid int(11) NOT NULL AUTO_INCREMENT,name VARCHAR(255) NOT NULL DEFAULT '',url VARCHAR(255) DEFAULT '',PRIMARY KEY (pid) ) ENGINE = InnoDB DEFAULT CHARSET = utf8;INSERT INTO permission VALUES ('1', 'add', ''); INSERT INTO permission VALUES ('2', 'delete', ''); INSERT INTO permission VALUES ('3', 'edit', ''); INSERT INTO permission VALUES ('4', 'query', '');-- 用戶表 -- CREATE TABLE user(uid int(11) NOT NULL AUTO_INCREMENT,username VARCHAR(255) NOT NULL DEFAULT '',password VARCHAR(255) NOT NULL DEFAULT '',PRIMARY KEY (uid) ) ENGINE = InnoDB DEFAULT CHARSET = utf8;INSERT INTO user VALUES ('1', 'admin', '123'); INSERT INTO user VALUES ('2', 'demo', '123');-- 角色表 -- CREATE TABLE role(rid int(11) NOT NULL AUTO_INCREMENT,rname VARCHAR(255) NOT NULL DEFAULT '',PRIMARY KEY (rid) ) ENGINE = InnoDB DEFAULT CHARSET = utf8;INSERT INTO role VALUES ('1', 'admin'); INSERT INTO role VALUES ('2', 'customer');-- 權(quán)限角色關(guān)系表 -- CREATE TABLE permission_role (rid int(11) NOT NULL ,pid int(11) NOT NULL ,KEY idx_rid (rid),KEY idx_pid (pid) ) ENGINE = InnoDB DEFAULT CHARSET = utf8;INSERT INTO permission_role VALUES ('1', '1'); INSERT INTO permission_role VALUES ('1', '2'); INSERT INTO permission_role VALUES ('1', '3'); INSERT INTO permission_role VALUES ('1', '4'); INSERT INTO permission_role VALUES ('2', '1'); INSERT INTO permission_role VALUES ('2', '4');-- 用戶角色關(guān)系表 -- CREATE TABLE user_role (uid int(11) NOT NULL ,rid int(11) NOT NULL ,KEY idx_uid (uid),KEY idx_rid (rid) ) ENGINE = InnoDB DEFAULT CHARSET = utf8;INSERT INTO user_role VALUES (1, 1); INSERT INTO user_role VALUES (2, 2);

//mapper的配置

1.掃描mapper的路徑

2.使用spring要告訴它掃描相關(guān)的注解

現(xiàn)在寫幾個case? ? ?需要些幾個realm? ? ?shiro的授權(quán)和登錄? ? ?需要實(shí)現(xiàn)相關(guān)的認(rèn)證和授權(quán)? ? 核心是自定義的realm
