[Java知识库]TkMybatis的使用

????????TKMybatis 是基于 Mybatis 框架开发的一个工具，内部实现了对单表的基本数据操作，只需要简单继承 TKMybatis 提供的接口，就能够实现无需编写任何 sql 即能完成单表操作。

依赖引入

<dependency>
   <groupId>tk.mybatis</groupId>
   <artifactId>mapper-spring-boot-starter</artifactId>
   <version>2.1.5</version>
</dependency>

BaseOptMapper.java

? ? ? ? 通用的操作类

import tk.mybatis.mapper.annotation.RegisterMapper;
import tk.mybatis.mapper.common.Marker;
import tk.mybatis.mapper.common.base.delete.DeleteMapper;
import tk.mybatis.mapper.common.base.insert.InsertMapper;
import tk.mybatis.mapper.common.base.insert.InsertSelectiveMapper;
import tk.mybatis.mapper.common.base.select.SelectCountMapper;
import tk.mybatis.mapper.common.base.select.SelectMapper;
import tk.mybatis.mapper.common.base.select.SelectOneMapper;
import tk.mybatis.mapper.common.base.update.UpdateByPrimaryKeyMapper;
import tk.mybatis.mapper.common.base.update.UpdateByPrimaryKeySelectiveMapper;

@RegisterMapper
public interface BaseOptMapper<T>
		extends SelectOneMapper<T>, SelectMapper<T>, SelectCountMapper<T>, InsertMapper<T>, InsertSelectiveMapper<T>,
		UpdateByPrimaryKeyMapper<T>, UpdateByPrimaryKeySelectiveMapper<T>, DeleteMapper<T>, Marker {

}

PersonDTO.java

? ? ? ? Person实体类，对应于person表

@Table(name = "person")
@JsonInclude(JsonInclude.Include.NON_NULL)
public class PersonDTO {

    private static final long serialVersionUID = 2242061288359096793L;

    @Id
    private UUID id;

    @ApiModelProperty(value = "姓名")
    @NotBlank(message = "姓名不能为空！")
    private String name;

    @ApiModelProperty(value = "地址")
    @NotBlank(message = "地址不能为空！")
    private String address;

    public UUID getId() {
        return id;
    }

    public void setId(UUID id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress() {
        return address;
    }

    public void setName(String address) {
        this.address = address;
    }
    
}

PersonMapper.java

@Mapper
public interface PersonMapper extends BaseOptMapper<PersonDTO> {
    
}

PersonController.java

@RestController
@RequestMapping("/person")
public class PersonController {

    @Autowired
    private PersonService personService;

    @PostMapping("/add")
    @ResponseBody
    public Result add(@Validated PersonDTO personDTO, BindingResult bindingResult) {
        if (bindingResult.hasErrors()) {
            return Result.error(bindingResult.getFieldError().getDefaultMessage());
        }
        int rows = personService.add(personDTO);
        return rows > 0 ? Result.ok() : Result.error();
    }
}

PersonService.java

public interface PersonService {
       int add(List<CarbonEmissionRecordDetailDTO> updates);
}

PersonServiceImpl.java

????????? 这里就写了插入，其他的类推。

@Service
@Transactional
public class PersonServiceImpl implements PersonService {

    @Autowired
    private PersonMapper personMapper;

    @Override
    public int add(PersonDTO param) {
        param.setId(UUID.randomUUID().toString());
        return personMapper.insertSelective(param);
    }
}
