博客详情页面包括文章内容和评论部分,本文将从文章内容显示和评论功能来讲述SpringBoot搭建个人博客的详情页面显示,由于博客详情和分类功能都是独立的,这里将评论单独用一个类来编写接口,查询博客详情就直接放在首页的控制器进行处理
分析:
问:博客详情页面是包含文章内容和评论部分,要如何处理
答:在跳转博客详情页面的时候,可以返回连个model,一个是文章详情内容,一个是评论列表
问:文章详情内容如何处理,需要哪些接口?评论如何处理,又需要哪些接口?
答:文章详情内容定义getDetailedBlog博客详情接口,需要定义一个查询实体类来封装一下查询内容,并把分类信息也包含进来;评论功能则需要定义listCommentByBlogId查询评论列表接口、saveComment新增保存接口、deleteComment删除接口
一、文章内容显示
分析:
问:在博客详情页面中,文章显示格式要如何处理,文章访问数量如何处理,评论数量又该如何处理?
答:这些都在getDetailedBlog接口实现类中实现
- 文章显示格式:使用开源的Markdown编辑器:Editor,调用工具类方法来增加扩展
- 访问数量:在持久层接口定义方法updateViews来更新文章访问数量,点击文章后数值自增
- 评论数量:在持久层接口定义方法getCommentCountById来根据博客id查询出评论数量
1. 博客详情实体类
博客详情除了显示博客信息外,还需要显示分类信息,所以还要创建分类名称属性,在queryvo包下创建DetailedBlog博客详情实体类,代码如下(省去get、set、toString方法):
package com.star.queryvo;
import java.util.Date;
/**
* @Description: 博客详情实体类
* @Date: Created in 10:10 2020/6/19
* @Author: ONESTAR
* @QQ群: 530311074
* @URL: https://onestar.newstar.net.cn/
*/
public class DetailedBlog {
//博客信息
private Long id;
private String firstPicture;
private String flag;
private String title;
private String content;
private Integer views;
private Integer commentCount;
private Date updateTime;
private boolean commentabled;
private boolean shareStatement;
private boolean appreciation;
private String nickname;
private String avatar;
//分类名称
private String typeName;
}
2. Markdown编辑器工具类
- 添加依赖Editor相关依赖
在pom.xml中添加
<dependency>
<groupId>com.atlassian.commonmark</groupId>
<artifactId>commonmark</artifactId>
<version>0.10.0</version>
</dependency>
<dependency>
<groupId>com.atlassian.commonmark</groupId>
<artifactId>commonmark-ext-heading-anchor</artifactId>
<version>0.10.0</version>
</dependency>
<dependency>
<groupId>com.atlassian.commonmark</groupId>
<artifactId>commonmark-ext-gfm-tables</artifactId>
<version>0.10.0</version>
</dependency>
- 添加MarkdownUtils工具类
在util工具包下添加MarkdownUtils工具类:
package com.star.util;
import org.commonmark.Extension;
import org.commonmark.ext.gfm.tables.TableBlock;
import org.commonmark.ext.gfm.tables.TablesExtension;
import org.commonmark.ext.heading.anchor.HeadingAnchorExtension;
import org.commonmark.node.Link;
import org.commonmark.node.Node;
import org.commonmark.parser.Parser;
import org.commonmark.renderer.html.AttributeProvider;
import org.commonmark.renderer.html.AttributeProviderContext;
import org.commonmark.renderer.html.AttributeProviderFactory;
import org.commonmark.renderer.html.HtmlRenderer;
import java.util.*;
/**

* @URL: https://onestar.newstar.net.cn/
*/
public class MarkdownUtils {
/**
* markdown格式转换成HTML格式
* @param markdown
* @return
*/
public static String markdownToHtml(String markdown) {
Parser parser = Parser.builder().build();
Node document = parser.parse(markdown);
HtmlRenderer renderer = HtmlRenderer.builder().build();
return renderer.render(document);
}
/**
* 增加扩展[标题锚点,表格生成]
* Markdown转换成HTML
* @param markdown
* @return
*/
public static String markdownToHtmlExtensions(String markdown) {
//h标题生成id
Set<Extension> headingAnchorExtensions = Collections.singleton(HeadingAnchorExtension.create());
//转换table的HTML
List<Extension> tableExtension = Arrays.asList(TablesExtension.create());
Parser parser = Parser.builder()
.extensions(tableExtension)
.build();
Node document = parser.parse(markdown);
HtmlRenderer renderer = HtmlRenderer.builder()
.extensions(headingAnchorExtensions)
.extensions(tableExtension)
.attributeProviderFactory(new AttributeProviderFactory() {
public AttributeProvider create(AttributeProviderContext context) {
return new CustomAttributeProvider();
}
})
.build();
return renderer.render(document);
}
/**
* 处理标签的属性
*/
static class CustomAttributeProvider implements AttributeProvider {
@Override
public void setAttributes(Node node, String tagName, Map<String, String> attributes) {
//改变a标签的target属性为_blank
if (node instanceof Link) {
attributes.put("target", "_blank");
}
if (node instanceof TableBlock) {
attributes.put("class", "ui celled table");
}
}
}
public static void main(String[] args) {
String table = "| hello | hi | 哈哈哈 |\n" +
"| ----- | ---- | ----- |\n" +
"| 斯维尔多 | 士大夫 | f啊 |\n" +
"| 阿什顿发 | 非固定杆 | 撒阿什顿发 |\n" +
"\n";
String a = "[ONESTAR](https://onestar.newstar.net.cn/)";
System.out.println(markdownToHtmlExtensions(a));
}
}
3. 持久层接口
文章内容显示是从首页点击文章标题或图片,然后跳转到博客详情页面的,所以这里就将代码放在博客业务这一块
在BlogDao接口中添加查询博客详情、文章访问更新、查询评论数量接口
//查询博客详情
DetailedBlog getDetailedBlog(Long id);
//文章访问更新
int updateViews(Long id);
//根据博客id查询出评论数量
int getCommentCountById(Long id);
4. mapper
根据持久层接口,编写如下SQL:查询博客详情、文章访问更新、查询评论数量,这里需要对博客详情进行封装
<resultMap id="detailedBlog" type="com.star.queryvo.DetailedBlog">
<id property="id" column="bid"/>
<result property="firstPicture" column="first_picture"/>
<result property="flag" column="flag"/>
<result property="title" column="title"/>
<result property="content" column="content"/>
<result property="typeName" column="name"/>
<result property="views" column="views"/>
<result property="commentCount" column="comment_count"/>
<result property="updateTime" column="update_time"/>
<result property="commentabled" column="commentabled"/>
<result property="shareStatement" column="share_statement"/>
<result property="appreciation" column="appreciation"/>
<result property="nickname" column="nickname"/>
<result property="avatar" column="avatar"/>
</resultMap>
<!--博客详情查询-->
<select id="getDetailedBlog" resultMap="detailedBlog">
select b.id bid,b.first_picture,b.flag,b.title,b.content,b.views,b.comment_count,b.update_time,b.commentabled,b.share_statement,b.appreciation, u.nickname,u.avatar,t.name
from myblog.t_blog b,myblog.t_user u, myblog.t_type t
where b.user_id = u.id and b.type_id = t.id and b.id = #{id}
</select>
<!--文章访问自增-->
<update id="updateViews" parameterType="com.star.entity.Blog">
update myblog.t_blog b set b.views = b.views+1 where b.id = #{id}
</update>
<!--查询出文章评论数量并更新-->
<update id="getCommentCountById" parameterType="com.star.entity.Blog">
update myblog.t_blog b set b.comment_count = (
select count(*) from myblog.t_comment c where c.blog_id = #{id} and b.id = #{id}
) WHERE b.id = #{id}
</update>
5. 持久层
- 持久层接口
在BlogService接口中添加查询博客详情方法:
//查询博客详情
DetailedBlog getDetailedBlog(Long id);
- 接口实现
次接口实现主要是设置文章显示格式,文章访问自增和文章评论的统计,在BlogServiceImpl类中添加实现方法,如下:
@Override
public DetailedBlog getDetailedBlog(Long id) {
DetailedBlog detailedBlog = blogDao.getDetailedBlog(id);
if (detailedBlog == null) {
throw new NotFoundException("该博客不存在");
}
String content = detailedBlog.getContent();
detailedBlog.setContent(MarkdownUtils.markdownToHtmlExtensions(content));
//文章访问数量自增
blogDao.updateViews(id);
//文章评论数量更新
blogDao.getCommentCountById(id);
return detailedBlog;
}
6. 控制器
在IndexController类中添加方法,调用业务层接口:
//跳转博客详情页面
@GetMapping("/blog/{id}")
public String blog(@PathVariable Long id, Model model) {
DetailedBlog detailedBlog = blogService.getDetailedBlog(id);
model.addAttribute("blog", detailedBlog);
return "blog";
}
二、评论功能
由于评论稍微复杂些,这里将评论单独放一个业务层
分析:
问:评论业务层需要哪些接口?
答:评论直接在前端页面上进行操作,没有后台管理,只是区分的管理员和普通用户,管理员可以对评论进行删除,因此需要查询评论列表(listCommentByBlogId)、添加保存评论(saveComment)、删除评论(deleteComment)接口
问:业务层这些接口够了,但持久层光这些够了吗?需要哪些SQL,需要哪些持久层接口呢?
答:持久层接口肯定是不够的,主要是查询评论列表的时候,需要将评论和回复加以区分,根据评论功能来看,有父评论、子评论(回复),并且父子评论在前端显示的位置有不同,这里细说一下查询:
- 根据id为“-1”和博客id查询出所有父评论(父级评论id为‘-1’)
- 根据父评论的id查询出一级子回复
- 根据子回复的id循环迭代查询出所有子集回复
- 将查询出来的子回复放到一个集合中
所以查询评论信息需要:查询父级评论(findByBlogIdParentIdNull)、查询一级回复(findByBlogIdParentIdNotNull)、查询二级回复(findByBlogIdAndReplayId)
1. 持久层接口
在dao包下创建CommentDao接口,添加如下接口:
package com.star.dao;
import com.star.entity.Comment;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;
import java.util.List;
/**
* @Description: 评论持久层接口
* @Date: Created in 9:21 2020/6/23
* @Author: ONESTAR
* @QQ群: 530311074
* @URL: https://onestar.newstar.net.cn/
*/
@Mapper
@Repository
public interface CommentDao {
//查询父级评论
List<Comment> findByBlogIdParentIdNull(@Param("blogId") Long blogId, @Param("blogParentId") Long blogParentId);
//查询一级回复
List<Comment> findByBlogIdParentIdNotNull(@Param("blogId") Long blogId, @Param("id") Long id);
//查询二级回复
List<Comment> findByBlogIdAndReplayId(@Param("blogId") Long blogId,@Param("childId") Long childId);
//添加一个评论
int saveComment(Comment comment);
//删除评论
void deleteComment(Long id);
}
2.mapper
在mapper目录下创建CommentDao.xml文件,添加如下:
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.star.dao.CommentDao">
<!--添加评论-->
<insert id="saveComment" parameterType="com.star.entity.Comment">
insert into myblog.t_comment (nickname,email,content,avatar,create_time,blog_id,parent_comment_id,admin_comment)
values (#{nickname},#{email},#{content},#{avatar},#{createTime},#{blogId},#{parentCommentId},#{adminComment});
</insert>
<!--查询父级评论-->
<select id="findByBlogIdParentIdNull" resultType="com.star.entity.Comment">
select *
from myblog.t_comment c
where c.blog_id = #{blogId} and c.parent_comment_id = #{blogParentId}
order by c.create_time desc
</select>
<!--查询一级子评论-->
<select id="findByBlogIdParentIdNotNull" resultType="com.star.entity.Comment">
select *
from myblog.t_comment c
where c.blog_id = #{blogId} and c.parent_comment_id = #{id}
order by c.create_time desc
</select>
<!--查询二级子评论-->
<select id="findByBlogIdAndReplayId" resultType="com.star.entity.Comment">
select *
from myblog.t_comment c
where c.blog_id = #{blogId} and c.parent_comment_id = #{childId}
order by c.create_time desc
</select>
<!--删除评论-->
<delete id="deleteComment" >
delete from myblog.t_comment where id = #{id}
</delete>
</mapper>
讲解:
添加删除:直接使用insert和delete即可进行添加和删除
查询:
- findByBlogIdParentIdNull:根据id为“-1”和博客id查询出所有父评论(父级评论id为‘-1’)
- findByBlogIdParentIdNotNull:根据父评论的id查询出一级子回复
- findByBlogIdAndReplayId:根据子回复的id循环迭代查询出所有子集回复
3. 业务层
- 业务层接口:
在service包下创建CommentService接口,如下:
package com.star.service;
import com.star.entity.Comment;
import java.util.List;
/**
* @Description: 评论业务层接口
* @Date: Created in 10:22 2020/6/23
* @Author: ONESTAR
* @QQ群: 530311074
* @URL: https://onestar.newstar.net.cn/
*/
public interface CommentService {
//根据博客id查询评论信息
List<Comment> listCommentByBlogId(Long blogId);
//添加保存评论
int saveComment(Comment comment);
//删除评论
void deleteComment(Comment comment,Long id);
}
- 接口实现:
在Impl包下创建接口实现类:CommentServiceImpl,功能都在这个接口中实现
package com.star.service.Impl;
import com.star.dao.BlogDao;
import com.star.dao.CommentDao;
import com.star.entity.Comment;
import com.star.service.CommentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

*/
@Service
public class CommentServiceImpl implements CommentService {
@Autowired
private CommentDao commentDao;
@Autowired
private BlogDao blogDao;
//存放迭代找出的所有子代的集合
private List<Comment> tempReplys = new ArrayList<>();

@Override
public List<Comment> listCommentByBlogId(Long blogId) {
//查询出父节点
List<Comment> comments = commentDao.findByBlogIdParentIdNull(blogId, Long.parseLong("-1"));
for(Comment comment : comments){
Long id = comment.getId();
String parentNickname1 = comment.getNickname();
List<Comment> childComments = commentDao.findByBlogIdParentIdNotNull(blogId,id);
//查询出子评论
combineChildren(blogId, childComments, parentNickname1);
comment.setReplyComments(tempReplys);
tempReplys = new ArrayList<>();
}
return comments;
}
/**

private void combineChildren(Long blogId, List<Comment> childComments, String parentNickname1) {
//判断是否有一级子评论
if(childComments.size() > 0){
//循环找出子评论的id
for(Comment childComment : childComments){
String parentNickname = childComment.getNickname();
childComment.setParentNickname(parentNickname1);
tempReplys.add(childComment);
Long childId = childComment.getId();
//查询出子二级评论
recursively(blogId, childId, parentNickname);
}
}
}
/**

private void recursively(Long blogId, Long childId, String parentNickname1) {
//根据子一级评论的id找到子二级评论
List<Comment> replayComments = commentDao.findByBlogIdAndReplayId(blogId,childId);
if(replayComments.size() > 0){
for(Comment replayComment : replayComments){
String parentNickname = replayComment.getNickname();
replayComment.setParentNickname(parentNickname1);
Long replayId = replayComment.getId();
tempReplys.add(replayComment);
recursively(blogId,replayId,parentNickname);
}
}
}
//新增评论
@Override
public int saveComment(Comment comment) {
comment.setCreateTime(new Date());
int comments = commentDao.saveComment(comment);
//文章评论计数
blogDao.getCommentCountById(comment.getBlogId());
return comments;
}
//删除评论
@Override
public void deleteComment(Comment comment,Long id) {
commentDao.deleteComment(id);
blogDao.getCommentCountById(comment.getBlogId());
}
}
4. 控制器
- 添加图片配置 在评论中,需要显示头像,这里直接在配置文件里面进行配置,在application.yml中添加如下配置(这里直接把后面留言的显示图片也一起添加了):
comment.avatar: /images/avatar.png
message.avatar: /images/avatar.png
在controller包下创建CommentController类,如下:
package com.star.controller;
import com.star.entity.Comment;
import com.star.entity.User;
import com.star.queryvo.DetailedBlog;
import com.star.service.BlogService;
import com.star.service.CommentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.servlet.mvc.support.RedirectAttributes;
import javax.servlet.http.HttpSession;
import java.util.List;
/**

* @URL: https://onestar.newstar.net.cn/
*/
@Controller
public class CommentController {
@Autowired
private CommentService commentService;
@Autowired
private BlogService blogService;
@Value("${comment.avatar}")
private String avatar;
//查询评论列表
@GetMapping("/comments/{blogId}")
public String comments(@PathVariable Long blogId, Model model) {
List<Comment> comments = commentService.listCommentByBlogId(blogId);
model.addAttribute("comments", comments);
return "blog :: commentList";
}
//新增评论
@PostMapping("/comments")
public String post(Comment comment, HttpSession session, Model model) {
Long blogId = comment.getBlogId();
User user = (User) session.getAttribute("user");
if (user != null) {
comment.setAvatar(user.getAvatar());
comment.setAdminComment(true);
} else {
//设置头像
comment.setAvatar(avatar);
}
if (comment.getParentComment().getId() != null) {
comment.setParentCommentId(comment.getParentComment().getId());
}
commentService.saveComment(comment);
List<Comment> comments = commentService.listCommentByBlogId(blogId);
model.addAttribute("comments", comments);
return "blog :: commentList";
}
//删除评论
@GetMapping("/comment/{blogId}/{id}/delete")
public String delete(@PathVariable Long blogId, @PathVariable Long id, Comment comment, RedirectAttributes attributes, Model model){
commentService.deleteComment(comment,id);
DetailedBlog detailedBlog = blogService.getDetailedBlog(blogId);
List<Comment> comments = commentService.listCommentByBlogId(blogId);
model.addAttribute("blog", detailedBlog);
model.addAttribute("comments", comments);
return "blog";
}
}
讲解:
查询评论列表:调用接口查询评论信息列表,局部刷新评论信息
新增评论:对评论进行判断,区分游客和管理员
删除评论:将博客id和评论id参数传入,判断删除的是哪一条评论,这里没有做迭代删除子评论,若删除了含有回复的评论,根据之前的查询来看,在前端回复也不会查询出来,但回复并没有删除,依然在数据库里面,删除的只是父评论
5. 前后端交互
给出部分前端代码,仅供参考,了解更多可以查看整个项目源码:https://github.com/oneStarLR/myblog-mybatis

三、运行访问
运行项目,访问 http://localhost:8080/, 点击一片文章,可以查看文章信息,并能进行评论,登录后可以对评论进行删除
至此,Springboot搭建个人博客详情页面显示开发完成,由于留言功能和评论功能基本一样,之前也写过一篇有关评论的博客(SpringBoot和Mybatis实现评论楼中楼功能(一张表搞定)),所以这里就不讲留言功能的开发了,还有不懂的伙伴可以问我,也可以加群讨论,下一篇就直接讲述分类、时间轴、音乐盒、友人帐、照片墙关于我页面的显示,比较简单,直接在一篇文章中讲完
