本文介绍了SpringBoot中几个常用类的封装实现，包括BaseBean、BaseItem、BaseTree等通用数据模型，以及Result用于统一返回结果的处理方式。同时提供了BaseController和BaseService作为控制器和服务层的基础类。

Spring Boot 常用类封装

BaseBean

@Data
public class BaseBean {
    // 当前页数，默认为1
    @Min(value = 1, message = "当前页数不合法")
    private Integer pageNum = 1;
    // 每页条数，默认为10
    @Min(value = 10, message = "条数不正确")
    private Integer pageSize = 10;
    // 用户ID
    private Integer userId;
}

BaseItem

@Data
public class BaseItem {
    private Integer id;
    private String name;
    @JsonInclude(JsonInclude.Include.NON_NULL)
    private List<BaseItem> children;
}

BaseTree

@Data
public class BaseTree {
    private String id;
    @JsonInclude(JsonInclude.Include.NON_NULL)
    private String code;
    private String name;
    @JsonInclude(JsonInclude.Include.NON_NULL)
    private List<BaseTree> children;
}

Result

@Data
@ToString
@AllArgsConstructor
@JsonInclude(JsonInclude.Include.NON_NULL)
public class Result {
    private Object state = Constant.HttpState.SUCCESS;
    private String message;
    private Object data;
    private Integer pageNum;
    private Integer total;

    public Result(Object state, String message) {
        this.state = state;
        this.message = message;
    }

    public Result(Object state, String message, Object data) {
        this.state = state;
        this.message = message;
        this.data = data;
    }
}

BaseController

public class BaseController {

    // protected Logger logger = LoggerFactory.getLogger(this.getClass());

    public BaseResult ok(String message) {
        return new BaseResult(true, message);
    }

    public BaseResult ok(String message, Object data) {
        return new BaseResult(true, message, data);
    }

    public BaseResult ok(Integer state, String message) {
        return new BaseResult(state, message);
    }

    public BaseResult ok(Integer state, String message, Object data) {
        return new BaseResult(state, message, data);
    }

    public BaseResult ok(String message, Object data, Integer pageNum, Long total) {
        return new BaseResult(true, message, data, pageNum, total.intValue());
    }

    public BaseResult ok(Integer state, String message, Object data, Integer pageNum, Long total) {
        return new BaseResult(state, message, data, pageNum, total.intValue());
    }


    public BaseResult error(String message) {
        return new BaseResult(false, message);
    }

    public BaseResult error(Integer state, String message) {
        return new BaseResult(state, message);
    }

    public BaseResult error(String message, Object data) {
        return new BaseResult(false, message, data);
    }
}

BaseService

public class BaseService {
    @Autowired
    @Qualifier("sqlSessionTemplate")
    private SqlSessionTemplate sqlSessionTemplate;

    protected SqlSessionTemplate getSqlSessionTemplate() {
        return sqlSessionTemplate;
    }

    public String getClassName(BaseService service) {
        return service.getClass().getSimpleName() + ".";
    }
}
