springboot 整合mybatis

1.创建maven 工程

2.引入springboot 必须的依赖

3.配置springboot的配置文件application.properties

#配置数据库连接参数

spring.datasourc.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.url=jdbc:mysql://localhost:3306/student

spring.datasource.username=root

spring.datasource.password=root

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

#jpa配置

spring.jpa.database=MYSQL

spirng.jpa.showsql=true

spring.jpa.hibernate.ddl-auto=update

spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

#mybatis的配置

mybatis.config=classpath:/config/sqlMapConfig.xml

mybatis.type-handlers-package=classpath:com/example/demo

mybatis.mapper-locations.classpath=classpath:/mapper/*.xml

#配置jsp的映射

4.加入mybatis 的核心配置文件和mapper映射文件

5.配置扫描器

package com.example.demo;

import org.mybatis.spring.annotation.MapperScan;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.autoconfigure.domain.EntityScan;

import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;

import org.springframework.boot.web.servlet.ErrorPage;

import org.springframework.context.annotation.Bean;

import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

import org.springframework.http.HttpStatus;
@SpringBootApplication

@MapperScan("com.example.demo.mapper")

@EnableJpaRepositories(basePackages = "cn.example.demo.dao.StudentDao")

@EntityScan(basePackages = "cn.example.demo.pojo")

public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}

}

使用spring的 时候该怎样注入OK!
