接着我们的spring boot项目，spring boot如何使用mybatis访问数据库呢？
个人习惯使用mapper接口和xml配置sql，从pom.xml入手
1.1 添加依赖
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.2.0</version>
</dependency>
<!--oracle驱动-->
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0.3.0</version>
<scope>${jar-scope}</scope>
</dependency>
1.2 application.properties配置
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@*.*.*.*:*/*
spring.datasource.username=*
spring.datasource.password=* mybatis.mapper-locations=classpath*:sqlmapper/*Mapper.xml
mybatis.type-aliases-package=hello.dal.model
1.3 编码
像其它项目一样mapper.xml，mapper接口，表model，服务service
1.4 修改启动类MyApplication.java
@SpringBootApplication
@MapperScan("hello.dal.mapper")
public class MyApplication
class类上添加注解MapperScan扫描mapper接口
经过以上步骤就可以在controller调用service访问数据库了
