这篇文章主要介绍了springboot整合通用mapper过程解析,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
找到springboot工程下的pom.xml文件,导入如下的依赖jar包
<!--配置通用Mapper start--> <dependency> <groupId>tk.mybatis</groupId> <artifactId>mapper-spring-boot-starter</artifactId> <version>2.1.5</version> </dependency> <!--通用Mapper end-->
配置UserDao接口,继承通用mapper,注意泛型
@Repository public interface UserDao extends Mapper<User> { }
Service的实现层
@Service("userService") public calss UserServiceImpl implements UserService{ @Autowired private UserDao userDao; @Override public List<User> list(){ return userDao.selectALL(); } }
User实体类配置通用文件mapper的主键和主键返回策略
import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; public class User { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer id; private String name; private Integer age; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } }
配置入口类Application
import tk.mybatis.spring.annotation.MapperScan;//把MapperScan的导入路径换成tk.mybatis.spring.annotation.MapperScan import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.transaction.annotation.EnableTransactionManagement; @SpringBootApplication @EnableTransactionManagement //开启书屋管理注解模式 最新的版本可以省略 @MapperScan("com.xz.springboot.mapper") //扫描该包下所有的接口并为该接口生成实现类 public class Springboot01Application { public static void main(String[] args) { SpringApplication.run(Springboot01Application.class, args); } }
