引入依赖
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter<artifactId>
<version>1.3.0</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>

在application.properties配置文件中引入数据源：
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
spring.http.multipart.maxFileSize=1000Mb
spring.http.multipart.maxRequestSize=1000Mb
***spring.datasource.url=jdbc:mysql://127.0.0.1:3306/publicPlatform?characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=1234
spring.datasource.driver-class-name=com.mysql.jdbc.Driver***
spring.jpa.properties.hibernate.hbm2ddl.auto=update
mybatis.mapper-locations=classpath:com/qianying/publicPlatform/mybatis/mapper/*.xml
mybatis.type-aliases-package=com.qianying.publicPlatform.mybatis.pojo
server.port=8888
通过****生产实体类,mapper 和mapper.xml(这里不需要再里面写sql语句)
再mapper中写CRUD的方法（这里只写一个示例）
@Delete("delete from re_keyword where KeywordId = #{KeywordId}")
int delete(int id);
创建service
写一个controller
