mybatis-plus批处理IService的实现示例

一、pom文件引入

    
      org.springframework.boot
      spring-boot-starter
    
    
com.baomidou
 mybatis-plus-boot-starter
 3.3.1.tmp
    
    
 com.baomidou
 mybatis-plus
 3.3.1.tmp
    
     
      mysql
      mysql-connector-java
      runtime
    
    
 org.springframework.boot
spring-boot-starter-web
    

二、Controller层

@RequestMapping("/user")
@RestController
public class UserController {
  @Autowired
   UserInfoService userInfoService;
  
  @RequestMapping("/add")
  public void addUser() {
    userInfoService.addUser();
  }
}

三、IService层（此处请确保继承的是 mybatisplus下的 IService，上述的ＵserInfoEntity为实体类）

import com.baomidou.mybatisplus.extension.service.IService;
import com.entity.UserInfoEntity;

public interface UserInfoService extends IService{
  
  public void addUser();

}

四、ServiceImpl（ＵserInfoDao和UserInfoEntitty分别为业务对应的UserEntityDao接口和UserInfoEntitty实体类）

@Service
public class UserInfoServiceImpl extends ServiceImpl implements UserInfoService{
  @Override
  public void addUser() {
    Random r=new Random(100);
    String str="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
     Random random=new Random();
    Set entityList=new HashSet();
    for(int i=0;i<1000000;i++) {
      UserInfoEntity entity=new UserInfoEntity();
      entity.setAge(r.nextInt());
      int number=random.nextInt(62);
      entity.setName(""+str.charAt(number));
      entity.setevaluate("good");
      entity.setFraction(r.nextLong());
      entityList.add(entity);
    }
    this.saveBatch(entityList);
  }

五、entity层

@TableName("user_info")//@TableName中的值对应着表名
@Data
public class UserInfoEntity {

  
  @TableId(type = IdType.AUTO)
  private Long id;
  
  private String name;
  
  private Integer age;
  
  private String skill;
  
  private String evaluate;
  
  private Long fraction;

六、Ｍapper接口层

@Mapper


public interface UserInfoDao extends baseMapper{

}
