原来的tao-dreamhouse改名为tao-disabuse，没有特别的原因，就觉得比较符合我想做的-3-（注意修改相关节点名称）

对tao-common的处理

package cn.zytao.taosir.common.model.disabuse;

import java.io.Serializable;
import java.util.Date;

import javax.persistence.Entity;
import javax.persistence.Id;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

@Data
@Entity
@ApiModel(value="疑惑信息")
public class Confusion implements Serializable{
    /**
     * 
     */
    private static final long serialVersionUID = 4105144790292919691L;
    
    @Id
    @ApiModelProperty(name ="id",value = "ID主键")
    private String id;
    
    @ApiModelProperty(name ="theme",value = "主题")
    private String theme;
    
    @ApiModelProperty(name ="content",value = "内容")
    private String content;
    
    @ApiModelProperty(name="question",value = "问题")
    private String question;
    
    @ApiModelProperty(name ="status",value = "当前状态：0待解惑-1正解惑-2已解惑")
    private Integer status;
    
    @ApiModelProperty(name ="details",value = "进度详情,json")
    private String details;
    
    @ApiModelProperty(name ="praise",value = "点赞数")
    private Integer praise;
    
    @ApiModelProperty(name ="presenter",value = "提出者")
    private String presenter;
    
    @ApiModelProperty(name ="answer",value = "采纳解答,json")
    private String answer;
    
    @ApiModelProperty(name ="createTime",value = "提出时间")
    private Date createTime;
    
    @ApiModelProperty(name ="endTime",value = "解惑时间")
    private Date endTime;
}

添加该实体类，并在数据库新增相关表

package cn.zytao.taosir.common.service.disabuse;

import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

import com.alibaba.fastjson.JSONObject;

import cn.zytao.taosir.common.model.disabuse.Confusion;

public interface ConfusionInterface {
    
    /**
     * 提出疑惑
     * @param confusion
     * @return
     */
    @RequestMapping(value="/confusion/solve",method=RequestMethod.POST)
    JSONObject solve(@RequestBody Confusion confusion);
    
    /**
     * 解答疑惑
     * @param answer
     * @return
     */
    @RequestMapping(value="/user/answer",method=RequestMethod.PUT)
    JSONObject answer(@RequestParam(value="id") String id,@RequestParam(value="key") String key,@RequestBody JSONObject answer);
    
    /**
     * 根据ID获取困惑相关信息
     * @param id
     * @return
     */
    @RequestMapping(value="/user/getConfusionById",method=RequestMethod.GET)
    JSONObject getConfusionById(@RequestParam(value="id") String id);
}

定义相关接口及要演示的方法

添加技术分享图片关于DataHandleUtils的相关说明，见 https://www.cnblogs.com/it-taosir/p/9860829.html

package cn.zytao.taosir.common.util;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.UUID;

public class DataHandleUtils {    
    /**
     * UUID创建随机主键
     * @param digits    位数
     * @return
     */
    public static String createRandNum(int digits) {
        return UUID.randomUUID().toString().replace("-", "").trim().substring(0,digits);
    }
    
    /**
     * 创建字符串日期
     * @param format    格式
     * @return
     */
    public static String createDate(String format) {
        return new SimpleDateFormat(format).format(new Date());
    }
}
