springboot整合mybatis即便用 **mapper.xml 02

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

1、導入相關依賴

<!--springboot web 所需依賴 -->
    <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的依賴 -->
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
    </dependency>
    
    <!-- 所需的mysql數據庫驅動 -->
    
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <!-- 數據庫鏈接池 -->
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
    </dependency>
複製代碼

2、編寫配置文件

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/數據庫名?characterEncoding=utf-8&useSSL=false
    username: 用戶名
    password: 密碼
    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

複製代碼

3、開始寫數據庫表對應的java對象，寫操做數據庫的接口 （同時與相應的 **mapper.xml）文件相映射 Eg:

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);

}
複製代碼

對應的**mapper.xml

<?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>
複製代碼

4、在寫一個controller訪問便可
