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);
}
}
