标签系统

一、增加拿手的兴趣标签和身份标签，用于后续商家增值服务使用，同时建立基础的用户画像。

1、系统增加两类标签

• 身份标签：
  • 身份标签为拿手的的用户属性，用于描述拿手的自身的特性，具体如下：
  • 时尚潮人
  • 数码极客
  • 文艺青年
  • 运动达人
  • 无敌辣妈
  • 御宅一族

• 兴趣标签：
  • 兴趣标签为淘宝的宝贝类目，用于了解拿手在淘宝上的消费习惯，具体标签内容如下：
  • 服装鞋包
  • 手机数码
  • 家用电器
  • 美妆饰品
  • 母婴用品
  • 家居建材
  • 百货食品
  • 运动户外
  • 文化玩乐
  • 生活服务
  • 汽配摩托

2、拿手手机端增加打标签的页面
• 拿手手机端新增两个页面，用于拿手身份标签和兴趣标签的选择，界面原型如下，设计稿界面待更新；
• 在设定标签的过程中，有可能会发生返回的操作，所以在最后点击“开启我的白拿拿之旅”时，进行保存的操作

3、标签页面触发入口

• 新注册用户：
  对于新注册的用户，完成注册或者绑定手机号完成后，直接进入上述的标签原则页，且拿手必须完成标签的选择后，才可进入到首页；
• 老用户
  对于已注册的用户，在返回的首页的时候（包括点击分享的链接、公众号底部菜单、其它页面返回首页等），如果未设定过身份标签和兴趣标签，则直接进入标签设定页，设定完成后才可以进入到首页；

4、保存设定的信息到拿手的标签中
• 拿手设定完成后，保存对应的身份标签和兴趣标签到该拿手的标签信息中，同时后台标签管理中，需要增加该拿手对应标签的展示

二、系统设计：

1、标签配置表：
实体类：

package com.zhibi.xiuba.user.spi.model;

import org.hibernate.annotations.GenericGenerator;
import org.hibernate.annotations.Type;

import javax.persistence.*;
import java.io.Serializable;
import java.util.Date;

/**
 * Created by QinHe on 2018-05-08.
 * 底层标签配置
 */
@Entity
@Table(name = "xb_us_tag_config")
public class TagConfig implements Serializable {
    private static final long serialVersionUID = -845329773606157910L;

    @Id
    @GeneratedValue(generator = "id_generator")
    @GenericGenerator(name = "id_generator", strategy = "redis_id")
    private Long id;

    /**
     * 父标签
     */
    @ManyToOne()
    @JoinColumn(updatable = false, name = "parent_id", referencedColumnName = "id")
    private TagConfig parent;

    /**
     * 标签层级 0为最顶层
     */
    private Integer level;

    /**
     * 用于排序
     */
    private Integer sortIndex;

    /**
     * 标签名字
     */
    private String name;

    /**
     * 标签描述
     */
    private String description;

    /**
     * 当下是否可用
     */
    @Type(type = "org.hibernate.type.NumericBooleanType")
    private Boolean enabled;

    private String dataType;

    private String iconUrl;

    private Date createTime;

    private Date updateTime;

    private Date deadLineTime;

    public Long getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public Boolean getEnabled() {
        return enabled;
    }

    public void setEnabled(Boolean enabled) {
        this.enabled = enabled;
    }

    public String getDataType() {
        return dataType;
    }

    public void setDataType(String dataType) {
        this.dataType = dataType;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public Date getUpdateTime() {
        return updateTime;
    }

    public void setUpdateTime(Date updateTime) {
        this.updateTime = updateTime;
    }

    public Date getDeadLineTime() {
        return deadLineTime;
    }

    public void setDeadLineTime(Date deadLineTime) {
        this.deadLineTime = deadLineTime;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public TagConfig getParent() {
        return parent;
    }

    public void setParent(TagConfig parent) {
        this.parent = parent;
    }

    public Integer getLevel() {
        return level;
    }

    public void setLevel(Integer level) {
        this.level = level;
    }

    public Integer getSortIndex() {
        return sortIndex;
    }

    public void setSortIndex(Integer sortIndex) {
        this.sortIndex = sortIndex;
    }

    public String getIconUrl() {
        return iconUrl;
    }

    public void setIconUrl(String iconUrl) {
        this.iconUrl = iconUrl;
    }
}

标签是分级的，这里面是用parent一个字段就可以表示层级关系了

2、用户标签对应表

实体类：

package com.zhibi.xiuba.user.spi.model;

import com.zhibi.xiuba.user.spi.enums.DataTypeEnum;
import com.zhibi.xiuba.utils.StringUtils;
import org.hibernate.annotations.GenericGenerator;
import org.hibernate.annotations.Type;

import javax.persistence.*;
import java.io.Serializable;
import java.util.Date;

/**

 * 增值业务配置类
 */
@Entity
@Table(name = "xb_us_tag_library")
public class TagLibrary implements Serializable {
    private static final long serialVersionUID = -4645714347119745836L;

    @Id
    @GeneratedValue(generator = "id_generator")
    @GenericGenerator(name = "id_generator", strategy = "redis_id")
    private Long id;

    /**
     * 标签 多对一
     */
    @ManyToOne
    @JoinColumn(nullable = false, updatable = false, name = "tag_config_id", referencedColumnName = "id")
    private TagConfig tagConfig;

    /**
     * 用户id
     */
    private Long userId;

    private String stringValue;

    private Date dateValue;

    private Long longValue;

    @Column(columnDefinition = "bit", length = 1)
    @Type(type = "org.hibernate.type.NumericBooleanType")
    private Boolean booleanValue;

    private Double doubleValue;


    private Date createTime;

    private Date updateTime;

    public TagLibrary() {
    }

    public TagLibrary(TagConfig tagConfig, Long userId, Date createTime) {
        this.tagConfig = tagConfig;
        this.userId = userId;
        this.createTime = createTime;
    }

    public void setValue(Object value, String dataType) {
        if (value != null && StringUtils.isNoneBlank(dataType)) {
            if (DataTypeEnum.DATA_TYPE_ENUM_STRING.getCode().equals(dataType)) {
                this.stringValue = (String) value;
            }
            if (DataTypeEnum.DATA_TYPE_ENUM_DATE.getCode().equals(dataType)) {
                this.dateValue = (Date) value;
            }
            if (DataTypeEnum.DATA_TYPE_ENUM_LONG.getCode().equals(dataType)) {
                this.longValue = (Long) value;
            }
            if (DataTypeEnum.DATA_TYPE_ENUM_BOOLEAN.getCode().equals(dataType)) {
                this.booleanValue = (Boolean) value;
            }
            if (DataTypeEnum.DATA_TYPE_ENUM_DOUBLE.getCode().equals(dataType)) {
                this.doubleValue = (Double) value;
            }
        }
        this.stringValue = value.toString();
        this.updateTime = new Date();
    }

    public Long getId() {
        return id;
    }

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

    public TagConfig getTagConfig() {
        return tagConfig;
    }

    public void setTagConfig(TagConfig tagConfig) {
        this.tagConfig = tagConfig;
    }

    public Long getUserId() {
        return userId;
    }

    public void setUserId(Long userId) {
        this.userId = userId;
    }

    public String getStringValue() {
        return stringValue;
    }

    public void setStringValue(String stringValue) {
        this.stringValue = stringValue;
    }

    public Date getDateValue() {
        return dateValue;
    }

    public void setDateValue(Date dateValue) {
        this.dateValue = dateValue;
    }

    public Long getLongValue() {
        return longValue;
    }

    public void setLongValue(Long longValue) {
        this.longValue = longValue;
    }

    public Boolean getBooleanValue() {
        return booleanValue;
    }

    public void setBooleanValue(Boolean booleanValue) {
        this.booleanValue = booleanValue;
    }

    public Double getDoubleValue() {
        return doubleValue;
    }

    public void setDoubleValue(Double doubleValue) {
        this.doubleValue = doubleValue;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public Date getUpdateTime() {
        return updateTime;
    }

    public void setUpdateTime(Date updateTime) {
        this.updateTime = updateTime;
    }
}

3、controller方法

package com.zhibi.xiuba.controller;

import com.alibaba.fastjson.JSON;
import com.zhibi.xiuba.model.ControllerResult;
import com.zhibi.xiuba.service.ITagService;
import com.zhibi.xiuba.user.spi.enums.TagConfigIdEnum;
import com.zhibi.xiuba.user.spi.model.TagConfig;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@Slf4j
@RestController
@RequestMapping("/user/tag/")
public class TagController {

    private final ITagService tagService;

    public TagController(ITagService tagService) {
        this.tagService = tagService;
    }

    @PostMapping("/makeTagForShowker")
    @ResponseBody
    public ControllerResult makeTagForShowker(@RequestParam Long showkerId,
                                              @RequestParam String identityTagJsonStr,
                                              @RequestParam String hobbyTagJsonStr) {


        List idsIdentity = tagService.findByUserIdAndTagParent(showkerId, TagConfigIdEnum.IDENTITY_TAG_ID.getCode());
        List idsHobby = tagService.findByUserIdAndTagParent(showkerId, TagConfigIdEnum.HOBBY_TAG_ID.getCode());
        if ((idsIdentity != null && idsIdentity.size() > 0) || (idsHobby != null && idsHobby.size() > 0)) {
            return ControllerResult.build(false, "", "您已经打过标签了！");
        }

        if (StringUtils.isNotBlank(identityTagJsonStr)) {
            List tagIds = JSON.parseArray(identityTagJsonStr, Long.class);
            if (tagIds != null) {
                if (tagIds.size() > 2) {
                    return ControllerResult.build(false, "", "最多可选两项！");
                }
                for (Long tagId : tagIds) {
                    tagService.createTagForUser(showkerId, tagId);
                }
            }
        }

        if (StringUtils.isNotBlank(hobbyTagJsonStr)) {
            List tagIds = JSON.parseArray(hobbyTagJsonStr, Long.class);
            if (tagIds != null) {
                if (tagIds.size() > 4) {
                    return ControllerResult.build(false, "", "最多可选四项！");
                }
                for (Long tagId : tagIds) {
                    tagService.createTagForUser(showkerId, tagId);
                }
            }

        }
        return ControllerResult.ok();
    }

    @GetMapping("/getIdentityTag")
    @ResponseBody
    public ControllerResult getIdentityTag(Long categoryId, Boolean enable) {
        List list = tagService.getIdentityTag(categoryId, enable);
        return ControllerResult.ok(list);
    }

}

4、业务逻辑层

package com.zhibi.xiuba.service.impl;

import com.zhibi.xiuba.repository.TagConfigRepository;
import com.zhibi.xiuba.repository.TagLibraryRepository;
import com.zhibi.xiuba.service.ITagService;
import com.zhibi.xiuba.user.spi.model.TagConfig;
import com.zhibi.xiuba.user.spi.model.TagLibrary;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.data.domain.Example;
import org.springframework.stereotype.Service;

import java.util.Date;
import java.util.List;

/**
 * Created by QinHe on 2018-07-02.
 */
@Service
public class TagService implements ITagService {

    private final TagLibraryRepository tagLibraryRepository;
    private final TagConfigRepository tagConfigRepository;


    public TagService(TagLibraryRepository tagLibraryRepository, TagConfigRepository tagConfigRepository) {
        this.tagLibraryRepository = tagLibraryRepository;
        this.tagConfigRepository = tagConfigRepository;
    }

    @Override
    public List findByUserIdAndTagParent(Long userId, Long tagParentId) {
        return tagLibraryRepository.findByUserIdAndTagParent(userId, tagParentId);
    }

    @Override
    @Cacheable(cacheNames = "Tag", key = "'categoryId_' + #categoryId+'_'+#enable")
    public List getIdentityTag(Long categoryId, Boolean enable) {
        TagConfig tagConfig = new TagConfig();
        TagConfig parent = new TagConfig();
        parent.setId(categoryId);
        tagConfig.setParent(parent);
        if (enable != null) {
            tagConfig.setEnabled(enable);
        }
        return tagConfigRepository.findAll(Example.of(tagConfig));
    }

    @Override
    public void createTagForUser(Long showkerId, Long tagId) {
        TagLibrary tagLibrary = new TagLibrary();
        tagLibrary.setCreateTime(new Date());
        tagLibrary.setUserId(showkerId);
        tagLibrary.setTagConfig(tagConfigRepository.findOne(tagId));
        tagLibraryRepository.save(tagLibrary);
    }
}
