spring boot 整合mybaits

1.引入依赖 

<!--mybatis -->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>1.3.2</version>
</dependency>

2.配置参数 

# mybatis 别名扫描
mybatis.type-aliases-package=cn.itcast.pojo
# mapper.xml文件位置,如果没有映射文件，请注释掉
mybatis.mapper-locations=classpath:mappers/*.xml

3. 配置mapper 接口扫描包 或 给每一个Mapper接口添加@Mapper注解

@Mapper
public interface UserMapper {
}

 

通用 mapper

<!-- 通用mapper -->
<dependency>
    <groupId>tk.mybatis</groupId>
    <artifactId>mapper-spring-boot-starter</artifactId>
    <version>2.0.2</version>
</dependency>

@Mapper
public interface UserMapper extends tk.mybatis.mapper.common.Mapper<User>{
}
