使用Spring boot怎么对Mybatis进行整合

这篇文章将为大家详细讲解有关使用Spring boot怎么对Mybatis进行整合，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。

1、文件结构

DataBaseConfiguration.Java用来获取数据库连接配置信息，配置从application.properties中读取

MybatisConfiguration.java也就是MyBatis配置核心入口，构建连接创建SqlSessionFactory

2、下面直接贴代码，有问题的话可以留言或者加我的微信公众号：cha-baba，或者个人微信号：benyzhous

application.yml 相关配置

Application.java

package com.modou.weixin; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.CommandLineRunner; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import com.modou.weixin.service.HelloWorldService;  @Configuration @ComponentScan(basePackages={"com.modou.conf","com.modou.weixin"}) @EnableAutoConfiguration public class Application implements CommandLineRunner{  @Autowired  HelloWorldService helloWorldService;  public static void main(String[] args) {   SpringApplication.run(Application.class, args);  }  @Override  public void run(String... args) throws Exception {   System.out.println(this.helloWorldService.print());  } }

maven pom.xml 相关依赖[我是基于我的多模块依赖，这里只是一个示意]，其中配置了jrebel热部署插件，需要搭配jrebel6.2.1，具体配置和下载请转向 http://blog.csdn.net/xiaoyu411502/article/details/48047369
