## 使用步骤
>步骤一：添加依赖
```xml
<!--mybatisplus的依赖-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.4.3.1</version>
        </dependency>
<!--springboot的依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
<!--MySQL的驱动-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>
<!--lombok简化bean-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
<!--springboot的单元测试-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
```  
>步骤二:配置数据源
```properties

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
##踩得的小坑,是pring.datasource.username而不是
##pring.datasource.name,这样会会是你window的登陆name
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.url=jdbc:mysql://192.168.163.163:3306/mybatis2?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai

```  
>步骤三:设置包扫描
```java
@Configuration
@MapperScan("com.lovexk.dao") //扫描包
public class MybatisPlusConfig {

    //分页
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }

//    自己插入主键时,生成主键 ;可以自己实现IdentifierGenerator接口
    @Bean
    public IdentifierGenerator identifierGenerator() throws UnknownHostException {

        InetAddress localHost = InetAddress.getLocalHost();
        return new DefaultIdentifierGenerator(localHost);
    }
}
```
