Springboot整合通用mapper过程解析

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);
 }
}
