1、新建一个maven工程和数据库

1.1maven web工程：

1.2数据库：

帖子表： 

评论表： 

 

 

2、新建相关工程目录：

 

3.在pom.xml中放入相关依赖包

4、配置相关核心配置：

（这里按照文件顺序来吧）

(注意：如果修改了包名，请修改相应的地方)

4.1TopicController:

package com.lemonsun.controller;


import com.lemonsun.pojo.Reply;
import com.lemonsun.pojo.Topic;
import com.lemonsun.service.TopicService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import java.io.UnsupportedEncodingException;
import java.sql.Timestamp;
import java.util.Date;
import java.util.List;


@Controller
public class TopicController{
    @Autowired
   private TopicService topicService;


    //查询所有帖子
    @RequestMapping("/topicListService.do")
    public String topicListService(Model model) {
   //去数据库查找所有帖子信息
        List<Topic> list = topicService.topicListService();
    //返回model层
        model.addAttribute("list", list);
        //返回帖子信息展示页面
        return "homepage";
    }

    //添加帖子
        @RequestMapping("/addTopicInf.do")
    public String addTopicInf(HttpServletRequest request) throws UnsupportedEncodingException {
        Topic topic = new Topic();
            topic.setTitle(new String(request.getParameter("title").getBytes("iso-8859-1"), "utf-8"));
            topic.setAuthor(new String(request.getParameter("author").getBytes("iso-8859-1"), "utf-8"));
            topic.setContent(new String(request.getParameter("context").getBytes("iso-8859-1"), "utf-8"));
            topic.setCretime(new Timestamp(new Date().getTime()));
            topicService.addTopicInf(topic);
            return "addSuccess";
    }

    //查看某个帖子信息
    @RequestMapping("/findAllTopicbyId.do")
    public String findAllTopicbyId(Integer id, Model model) {
        //点击量加一
             topicService.add_click_amount_byId(id);
         //获取帖子信息
        Topic topic = topicService.findAllTopicbyId(id);
        System.out.println("topic:"+topic);
        model.addAttribute("topic", topic);
       //获取评论信息
        List<Topic> replylist = topicService.findAllReplyId(id);
        model.addAttribute("replylist", replylist);
        //传入帖子id
        model.addAttribute("topicId", id);

        //返回客户信息展示页面
        return "showTopic";
    }

    //添加评论
    @RequestMapping("/addReplyInf.do")
    public String addReplyInf(HttpServletRequest request,Model model) throws UnsupportedEncodingException {
        Reply reply = new Reply();
        //测试是否获取到该帖子的id
        String id = request.getParameter("topicid");
   //因为转码的问题
        reply.setAuthon(new String(request.getParameter("reply_author").getBytes("iso-8859-1"), "utf-8"));
        reply.setContent(new String(request.getParameter("reply_context").getBytes("iso-8859-1"), "utf-8"));
        reply.setT_id(new Integer(request.getParameter("topicid")));
      //设置当前时间
        reply.setCretime(new Timestamp(new Date().getTime()));
      //返回给方法 去数据库添加
        topicService.addReplyInf(reply);
       //添加成功 到成功界面
        return "addSuccessReply";
    }


}

4.2CustomerDao

（dao层实现与数据库的交互，具体实现在.xml里）

package com.lemonsun.dao;

import com.lemonsun.pojo.Reply;
import com.lemonsun.pojo.Topic;

import java.util.List;

/**
 * Customer接口文件
 */
public interface CustomerDao {


    //查询所有帖子
    List<Topic> topicListService();

    //添加帖子
     int addTopicInf(Topic topic);

    //查看某个帖子信息
    Topic findAllTopicbyId(Integer id);

     //点击量自增                      
     int add_click_amount_byId(Integer id);

    //查看某个帖子评论信息
    List<Topic> findAllReplyId(Integer id);

    //添加评论
       int addReplyInf(Reply reply);

}

4.3Reply

(评论实体类，注意创建实体时，尽量与数据库对应的名字一样)

package com.lemonsun.pojo;

import java.sql.Timestamp;
/*
*评论
 */
public class Reply {

    //评论id
    private int reply_id;
    //被评论的帖子id
    private int topic_id;
    //评论者
    private String author;
    //评论时间
    private Timestamp cretime;

    //评论内容
    private String content;

    public Reply() {
    }

    public Reply(int r_id, int t_id, String author, Timestamp cretime, String content) {
        this.reply_id = r_id;
        this.topic_id = t_id;
        this.author = author;
        this.cretime = cretime;
        this.content = content;
    }

    public int getR_id() {
        return reply_id;
    }

    public void setR_id(int r_id) {
        this.reply_id = r_id;
    }

    public int getT_id() {
        return topic_id;
    }

    public void setT_id(int t_id) {
        this.topic_id = t_id;
    }

    public String getAuthon() {
        return author;
    }

    public void setAuthon(String authon) {
        this.author = authon;
    }

    public Timestamp getCretime() {
        return cretime;
    }

    public void setCretime(Timestamp cretime) {
        this.cretime = cretime;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    @Override
    public String toString() {
        return "Reply{" +
                "r_id=" + reply_id +
                ", t_id=" + topic_id +
                ", authon='" + author + '\'' +
                ", cretime=" + cretime +
                ", content='" + content + '\'' +
                '}';
    }
}

4.4Topic

（帖子实体类）

package com.lemonsun.pojo;


import java.sql.Timestamp;
/*
*贴子表
 */
public class Topic {
    //帖子编号
      private Integer id;
      //标题
      private String title;
      //内容
      private String content;
      //作者
      private String author;
      //发帖时间
      private Timestamp create_time;
      //点击量
      private int click_amount;

      //评论
    private Reply reply;


    public Topic() {
    }

    public Topic(String title, String author,  Timestamp cretime, int amount) {
        this.title = title;
        this.author = author;
        this.create_time = cretime;
        this.click_amount = amount;
    }

    public Topic(Integer id, String title, String content, String author,  Timestamp cretime, int amount) {
        this.id = id;
        this.title = title;
        this.content = content;
        this.author = author;
        this.create_time = cretime;
        this.click_amount = amount;
    }

    public Topic(Integer id, String title, String content, String author, Timestamp cretime, int amount, Reply reply) {
        this.id = id;
        this.title = title;
        this.content = content;
        this.author = author;
        this.create_time = cretime;
        this.click_amount = amount;
        this.reply = reply;
    }

    public Reply getReply() {
        return reply;
    }

    public void setReply(Reply reply) {
        this.reply = reply;
    }

    public Integer getId() {
        return id;
    }

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

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

    public  Timestamp getCretime() {
        return create_time;
    }

    public void setCretime( Timestamp cretime) {
        this.create_time = cretime;
    }

    public int getAmount() {
        return click_amount;
    }

    public void setAmount(int amount) {
        this.click_amount = amount;
    }

    @Override
    public String toString() {
        return "Topic{" +
                "id=" + id +
                ", title='" + title + '\'' +
                ", content='" + content + '\'' +

                ", amount=" + click_amount +
                '}';
    }


}

4.5TopicService

package com.lemonsun.service;

import com.lemonsun.pojo.Reply;
import com.lemonsun.pojo.Topic;

import java.util.List;

/*
*服务层接口
 */

public interface TopicService {

    //查看某个帖子评论信息
    List<Topic> findAllReplyId(Integer id);

    //添加评论
    int addReplyInf(Reply reply);

}

4.6TopicServiceImpl

    }

    //发表帖子
