引入pom依賴
在使用Spring Boot進(jìn)行數(shù)據(jù)庫(kù)交互時(shí)，我們需要在項(xiàng)目的pom.xml文件中引入相關(guān)的依賴。具體依賴包括druid、mysql-connector-java和mybatis-spring-boo

druid啟動(dòng)配置
為了讓Spring Boot項(xiàng)目能夠使用druid連接池，我們需要在項(xiàng)目中添加一個(gè)配置類（）。這個(gè)配置類主要完成三個(gè)任務(wù)：設(shè)置連接參數(shù)、獲取SqlSessionFactory對(duì)象和獲取數(shù)據(jù)源。
```java
@Configuration
@MapperScan("mybatis") // 掃描mapper接口包
public class mybatisConfig implements EnvironmentAware {
@Resource
private Environment environment;
private RelaxedPropertyResolver propertyResolver;
// EnvironmentAware接口的默認(rèn)實(shí)現(xiàn)方法，默認(rèn)掃描屬性
public void setEnvironment(Environment environment) {
this.environment environment;
new RelaxedPropertyResolver(environment, "");
}
// 獲得SqlSessionFactory對(duì)象
@Bean
public SqlSessionFactory SqlSessionFactoryBean() throws Exception {
SqlSessionFactoryBean sqlSessionFactoryBean new SqlSessionFactoryBean();
(dataSource());
PathMatchingResourcePatternResolver resolver new PathMatchingResourcePatternResolver();
(("classpath*:mybatis/*.xml"));
return ();
}
// 獲得DataSource對(duì)象
@Bean
public DataSource dataSource() {
DruidDataSource druidDataSource new DruidDataSource();
(("driver-class-name"));
(("url"));
(("username"));
(("password"));
return druidDataSource;
}
}
```
