springboot整合mybatis

<dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.0</version>
        </dependency>

optionz注解将自增后得到的主键的值映射到javabean中

 
    @Options(useGeneratedKeys = true,keyProperty = "id")
    @Insert("insert into teacher(name,age) values(#{teacherName},#{age})")
    int insertTeacher(Teacher teacher);

配置表的列名字和javabean中支持驼峰式映射
参考 MybatisAutoConfiguration

@Configuration
public class MybatisConfig {

    @Bean
    public ConfigurationCustomizer config(){
        return (org.apache.ibatis.session.Configuration configuration)->{
           configuration.setMapUnderscoreToCamelCase(true);
        };
    }

}
