博客中的文章归档是如何实现的

Posted 2021-02-15 youcong

我的效果图如下(这个是我实现的):

wordpress的效果图如下:

sql代码:

SELECT DISTINCT YEAR(post.post_modified)AS `year`,MONTH(post.post_modified) AS `month` FROM wp_posts AS post

dao代码:

package com.blog.springboot.dao;

import java.util.List;
import java.util.Map;

import com.baomidou.mybatisplus.mapper.BaseMapper;
import com.blog.springboot.entity.Posts;


public interface PostsDao extends BaseMapper<Posts> {
    //文章归档
    public List<Posts> articleArchive();


}

service代码:

public interface PostsService extends IService<Posts> {
    //文章归档
    public List<Posts> articleArchive();
}

实现类:

package com.blog.springboot.service.impl;

import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.baomidou.mybatisplus.mapper.EntityWrapper;
import com.baomidou.mybatisplus.plugins.Page;
import com.baomidou.mybatisplus.service.impl.ServiceImpl;
import com.blog.springboot.dao.PostsDao;
import com.blog.springboot.entity.Posts;
import com.blog.springboot.service.PostsService;



@Service
public class PostsServiceImpl extends ServiceImpl<PostsDao, Posts> implements PostsService {
    
    @Autowired
    private PostsDao postDao;

    
    @Override
    public List<Posts> articleArchive() {

        return postDao.articleArchive();
    }

    

}

后台Controller:

/**
     * 文章归档
     * @return
     */
    @GetMapping(value="/articleArchive")
    public JSONObject writePost() {
        
        List<Posts> post = postService.articleArchive();
        
        if(!post.isEmpty()) {
            
            json.put("code", "000000");
            json.put("msg", "获取文章归档");
            json.put("post", post);
        }else {
            
            json.put("code", "222222");
            json.put("msg", "暂无文章归档");
        }
        return json;
    }

前端js实现:

//文章归档
function articleArchive(){

                $.ajax({
        url: Blog.url.api.articleArchive,
        type: "GET",
        dataType: ‘json‘,
        success: function(data) {
            
            var rows = "";
            $.each(data.post, function(index, post) {
                 var year = post.year+"年";
                 var month = post.month+"月";
                 var date = year + month;
                 rows= rows +"";
                 rows= rows +"<li><a href=‘#‘>"+date+"</a></li>";
                 rows= rows +"<hr/>";
            });
            
            $("#articleArchive").html(rows);
            
        },
        error: function(XMLHttpRequest, textStatus, errorThrown) {

            console.log(XMLHttpRequest.status);

            console.log(XMLHttpRequest.readyState);

            console.log(textStatus);
        }
    });
}
