一、創建項目並導入相關依賴

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-security</artifactId>

</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

<dependency>

<groupId>org.mybatis.spring.boot</groupId>

<artifactId>mybatis-spring-boot-starter</artifactId>

<version>2.1.1</version>

</dependency>

<dependency>

<groupId>com.alibaba</groupId>

<artifactId>druid-spring-boot-starter</artifactId>

<version>1.1.10</version>

</dependency>

<dependency>

<groupId>mysql</groupId>

<artifactId>mysql-connector-java</artifactId>

<scope>runtime</scope>

<version>5.1.27</version>

</dependency>

注：maven默認不編譯src/main/java下的xml文件，需要我們手動導入

二、相關配置和代碼

1）application.properties

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/security

spring.datasource.username=root

spring.datasource.password=123

2）數據庫腳本
