Spring Boot 整合mybatis

1、创建entity、mapper接口、映射文件；//逆向工程；

2、在springboot添加mybatis和mysql驱动的依赖：

        <!--springboot整合mybatis-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>


        <build>
            <resources>
                <resource>
                    <directory>src/main/java</directory>
                    <includes>
                        <include>**/*.xml</include>
                    </includes>
                </resource>
            </resources>
            </build>

3、编写ssm业务；

4、在springboot的启动程序上添加@MapperScan("com.java.mapper")注解，指明mapper接口所在的路径；

　　//让springboot去扫描到这些mapper；

5、springboot的application.yml进行配置：

 

　　//密码0开头需要“”引号括起来；

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/db_1904?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=Asia/Shanghai
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: 123456
