java+数据库+D3.js 实时查询人物关系图

先看下 效果

某个用户,邀请了自己的朋友 ,自己的朋友邀请了其他朋友,1 展示邀请关系,2 点击头像显示邀请人和被邀请人的关系。(网上这种资料很少, 另外很多都是从JSON文件取 数据, 这里是从数据库取数据)

=================================================================================================需求:Java从数据库查用户表,管理平台可以实时查看每个月用户的邀请关系图。

以下是代码:

1.Java 方法

    1.1 controller 根据某个手机号码查出JSON

 

    /**
     * @param model
     * @param mobile
     * @return
     */
    @RequestMapping(value = "/relation")
    public ModelAndView toRelation(Model model,@RequestParam("mobile")String mobile) {
        String userName= AuthUtils.getAuthenticationObject().getName();
        Customer user =userService.getUserByname(userName);
        model.addAttribute("role", user.getRole());
        model.addAttribute("username", user.getMobile());
        JSONObject json = customerService.findUserRelation(mobile);
        model.addAttribute("json", json);
        
        System.out.println(json);
        return new ModelAndView("relation");
    }
    

 

1.2 service 方法(递归查询,JSON处理)

    /**
     * 根据手机号码查询人物关系图
     * @param mobile
     * @return
     */
    public JSONObject findUserRelation(String mobile) {
        JSONObject json = new JSONObject();
        // 首先查询当前用户
        Customer customer = userService.getUserByname(mobile);
        List<RelationBo> list = new ArrayList<RelationBo>();
        // 根节点,只看子类
        // 递归获取当前用户的所有子类。
        list = getAllRelation(new ArrayList<RelationBo>(), customer.getUid());
        list.add(0, new RelationBo(mobile,Constants.TOP_USER,
                customer.getUid(), null));
        // 获取用户信息JSONArray
        JSONArray peopleArray = new JSONArray();
        JSONArray targetArray = new JSONArray();
        SourceTargetBo bo = null;
        JSONObject peoJ= null;
        
        List<String> photoList= RelationUtil.getRandomPhoto();
        for (int i = 0; i < list.size(); i++) {
            peoJ=new JSONObject();
            peoJ.put("name", list.get(i).getName());
//            peoJ.put("image", list.get(i).getImage());
            peoJ.put("image", photoList.get(i));
            peopleArray.add(peoJ);
            for (int j = 0; j < list.size(); j++) {
                if(list.get(j).getPuid()==null||list.get(j).getPuid()==list.get(i).getUid()){
                    continue;
                }
                if (list.get(i).getUid().equals(list.get(j).getPuid())) {
                    bo = new SourceTargetBo(i, j,"resolved",RelationUtil.getRelation());
                    // 找到子类序号
                    targetArray.add(bo);

                }
            }

        }
        // 人物JSON
        json.put("nodes", peopleArray);
        // 关系JSON
        json.put("edges", targetArray);
        return json;
    }

    private List<RelationBo> getAllRelation(List<RelationBo> bo, String uid) {
        // 查询这个用户下的所有子用户
        List<Customer> list = customerDao.findAllChild(uid);
        RelationBo relation = null;
        if (list == null || list.size() == 0) {
            // 当前用户没有子用户了!
            return bo;
        } else {
            for (Customer cus : list) {
                relation = new RelationBo(cus.getMobile(), Constants.BOOTOM_USER,
                        cus.getUid(), cus.getPuid());
                // 所有子用户添加到树中
                bo.add(relation);
                // 递归查询子用户的所有子用户
                bo = getAllRelation(bo, cus.getUid());

            }

        }
        return bo;
    }

 

1.3 mybatis

<select id="findAllChild" resultType="com.ycmedia.entity.Customer">
    select * from r_user where puid=#{uid}
    </select>

1.4 数据库 因为数据库暂时没有用户头像,所以随机工具类定义了几个头像

1.5 工具类, 获得随机关系, 用户头像

package com.ycmedia.utils;

import java.util.ArrayList;
import java.util.List;
import java.util.Random;

public class RelationUtil {
    
    
    public static String getRelation(){
        
        List<String> list = new ArrayList<String>();
        list.add("");
        list.add("亲人");
        list.add("同学");
        list.add("朋友");
        list.add("同事");
        list.add("邻居");
        int Num=new Random().nextInt(4)+1;
        return list.get(Num);
        
    }
    
    
    public static List<String> getRandomPhoto(){
        
        List<String> list = new ArrayList<String>();
        list.add("http://apps.ycmedia.cn/qm/img/31f96dc747eb4e4383ab7f990afc9775.jpg");
        list.add("http://appdemo.b0.upaiyun.com/qm/img/lable/60x60/1480730644618.jpg");
        list.add("http://appdemo.b0.upaiyun.com/qm/img/lable/60x60/1480730825975.jpg");
        list.add("http://appdemo.b0.upaiyun.com/qm/img/lable/60x60/1480730901129.jpg");
        list.add("http://appdemo.b0.upaiyun.com/qm/img/lable/60x60/1480730947894.jpg");
        return list;
    }
    


}

以上就是全部代码, 目前未实现箭头,昨天搞了好长时间, 没弄出来, Java的画图工具不行, 太丑, 现在D3Js 很火,这里做个参考
