Spring+SprinMVC+MyBatis配置方式简易模板

Spring+SprinMVC+MyBatis配置方式简易模板代码Demo GitHub访问 ssm-tpl-cfg

一、SQL数据准备

创建数据库test，执行下方SQL创建表ssm-tpl-cfg

/*Navicat Premium Data TransferSource Server         : 127.0.0.1Source Server Type    : MySQLSource Server Version : 80030Source Host           : 127.0.0.1:3306Source Schema         : testTarget Server Type    : MySQLTarget Server Version : 80030File Encoding         : 65001Date: 17/10/2022 00:52:07
*/SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;-- ----------------------------
-- Table structure for ssm-tpl-cfg
-- ----------------------------
DROP TABLE IF EXISTS `ssm-tpl-cfg`;
CREATE TABLE `ssm-tpl-cfg` (`id` bigint NOT NULL COMMENT '主键编号',`name` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '测试名称',PRIMARY KEY (`id`)
) COMMENT '初始SSM表结构数据' ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;-- ----------------------------
-- Records of ssm-tpl-cfg
-- ----------------------------
BEGIN;
INSERT INTO `ssm-tpl-cfg` (`id`, `name`) VALUES (2210162246100000, '王飞飞');
INSERT INTO `ssm-tpl-cfg` (`id`, `name`) VALUES (2210162257100000, '练卓神');
COMMIT;SET FOREIGN_KEY_CHECKS = 1;

三、访问测试

访问 http://127.0.0.1:8080/ssm_tpl_cfg/test/

一个简易基于配置的增删改查就实现了
