SpringBoot与Mybatis-Plus集成（二）

项目结构：

1）创建一个SpringBoot项目

2）引入依赖

	<properties>
		<java.version>1.8</java.version>
		<maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
		<mybatisplus.version>3.2.0</mybatisplus.version>
	</properties>

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

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-devtools</artifactId>
			<scope>runtime</scope>
			<optional>true</optional>
		</dependency>
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<scope>runtime</scope>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-configuration-processor</artifactId>
			<optional>true</optional>
		</dependency>
		<dependency>
			<groupId>org.projectlombok</groupId>
			<artifactId>lombok</artifactId>
			<optional>true</optional>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>com.baomidou</groupId>
			<artifactId>mybatis-plus-boot-starter</artifactId>
			<version>${mybatisplus.version}</version>
		</dependency>
	</dependencies>

	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

3）配置application.yml

#数据源
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=true&serverTimezone=UTC
    username: root
    password: 123456
    type: org.springframework.jdbc.datasource.DriverManagerDataSource
#配置mybatisplus
mybatis-plus:
  mapper-locations:
  - classpath:mapper/*Mapper.xml
  global-config:
    db-config:
      id-type: auto
    banner: true

4）编写Config配置类

@SpringBootApplication
@MapperScan(basePackages={"com.demo.mapper"})
public class Application {
	public static void main(String[] args) {
        SpringApplication.run(Application.class,args);
	}
}

5）编写HelloController对象

6）运行main，访问网站进行测试
