SpringBoot中整合Mybatis

本次使用的数据源为Druid，引入相关依赖，在build.gradle中的dependencies里编写

	implementation 'org.mybatis:mybatis:3.5.9'
	implementation 'com.alibaba:druid:1.2.8'
	implementation 'org.mybatis.spring.boot:mybatis-spring-boot-starter:2.2.1'
	implementation 'mysql:mysql-connector-java:8.0.28'

在application.yml文件中编写如下配置：

spring:
  mxzero:
    datasource:
      type: com.alibaba.druid.pool.DruidDataSource
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://127.0.0.1:3306/ssmblog
      username: root
      password: mysqladmin


mybatis:
  config-location: classpath:meta-INF/mybatis/mybatis-config.xml
  type-aliases-package: top.mxzero.po
  mapper-locations: classpath:meta-INF/mybatis/mapper*.xml

创建一个配置类：

@Configuration
public class DruidConfig {
    @Bean
    public DataSource dataSource(
            @Value("${spring.mxzero.datasource.driver-class-name}")
            String driverClassName,
            @Value("${spring.mxzero.datasource.url}")
            String url,
            @Value("${spring.mxzero.datasource.username}")
            String username,
            @Value("${spring.mxzero.datasource.password}")
            String password
    ){
        DruidDataSource druidDataSource = new DruidDataSource();
        druidDataSource.setDriverClassName(driverClassName);
        druidDataSource.setUrl(url);
        druidDataSource.setUsername(username);
        druidDataSource.setPassword(password);
        return druidDataSource;
    }
}

在resource目录下创建meta-INF子目录，再在meta-INF下创建mybatis子目录，目录结构在application.yml中配置相对应

 在resource/meta-INF/mybatis下创建mybatis配置文件
