SpringBoot(04)--整合mybatis

SpringBoot(04)--整合mybatis

薛定谔的汪

记录Spring Boot如何整合MyBatis框架,并访问数据库。

没有使用mybatis注解,而是使用xml方式,这样可以让sql和业务代码分离,很清晰方便。

搭建环境

使用IDEA快速创建springboot项目,选择web,mysql,mybatis,等依赖,具体配置如下:

数据源配置–使用 Spring Boot 配置

编写application.properties文件,填写如下配置:

#数据库配置
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3307/sboot?useUnicode = true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
spring.datasource.username=root
spring.datasource.password=yakai
#mybatis
mybatis.config-locations=classpath:mybatis/mybatis-config.xml
mybatis.mapper-locations=classpath:mybatis/sqlMap/*.xml

启动类配置

@SpringBootApplication
@MapperScan("com.yakai.mybatis.dao") //开启mapper自动扫描 这样不需要在每个Mapper上加@Mapper
@EnableTransactionManagement //事物自动开启
public class MybatisApplication {
public static void main(String[] args) {
SpringApplication.run(MybatisApplication.class, args);
}
}

初始化数据库

CREATE DATABASE `sboot`;
USE `sboot`;
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '用户ID',
`username` varchar(255) DEFAULT NULL COMMENT '用户名',
`password` varchar(255) DEFAULT NULL COMMENT '密码',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

整合MyBatis(极简xml方式)

使用generator插件自动创建bean,mapper,xml….

最终目录结构如下:

接下来可以对数据库进行增删改查的操作了……………
