用于测试的最小Spring Boot配置所需

目的：使用Spring Boot快速进行MyBatis和MySQL的简单测试

1.配置依赖。需要设置<parent>然后

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>

        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
        </dependency>

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

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
        
    </dependencies>

2.Spring Boot配置类

@SpringBootApplication
@EnableTransactionManagement
@MapperScan("com.doubt.test.transaction")
public class SpringBootApp {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootApp.class);
    }
}

3.application.yml文件

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8
    username: root
    password: root

4.dao类（简单的话就不用mybatis的xml，直接使用注解写sql语句的方式），service类，测试类。
