1.如何在springboot中整合Mybatis，并使用 **mapper.xml ？

1、导入相关依赖java

<!--springboot web 所需依赖 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
    </dependency>
    
    <!--springboot 整合mybatis 所需mybatis的依赖 -->
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
    </dependency>
    
    <!-- 所需的mysql数据库驱动 -->
    
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <!-- 数据库链接池 -->
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
    </dependency>

2、编写配置文件mysql

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/数据库名?characterEncoding=utf-8&useSSL=false
    username: 用户名
    password: 密码
    driver-class-name: com.mysql.jdbc.Driver
#配置mybatis 所需映射的mapper.xml 文件的位置
mybatis:
  mapper-locations: classpath:mapper/*.xml
  #type-aliases-package: com.fancy.account.spu.dbobject

复制代码

3、开始写数据库表对应的java对象，写操做数据库的接口（同时与相应的 **mapper.xml）文件相映射 Eg:web

接口：
//@Mapper
public interface TSpuDao {

    void addSpu(@Param("spuName") String spuName, @Param("spuHeadphoto") String spuHeadphoto, @Param("spuDetailphoto") String spuDetailphoto, @Param("spuDecphoto") String spuDecphoto,@Param("spuStatus") int spuStatus);

}
复制代码

对应的**mapper.xmlspring

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    <mapper namespace="com.fancy.account.spu.dao.TSpuDao">
    
        <insert id="addSpu" parameterType="com.fancy.account.spu.dbobject.TSpu">
            insert into t_spu (spu_name,spu_headphoto,spu_detailphoto,spu_decphoto,spu_status)
            values (#{spuName},#{spuHeadphoto},#{spuDetailphoto},#{spuDecphoto},#{spuStatus})
        </insert>
    
    </mapper>
复制代码

4、在写一个controller访问便可sql
