实训日记【15】文章功能

为了实现文章功能，需要在数据库当中建立数据表。

package kc.model;

import lombok.Data;

import java.sql.Date;
import java.util.Calendar;

@Data
public class Article {
    private String id; //主键

    private String title; //标题

    private String name; //文章名称

    private String content; //文章内容

    private String author; //作者

    private String description = ""; //概要

    private Integer isPublished = 0; //是否发布 0 未发布 1 发布

    private Integer isDelete = 0;      //是否删除   0 未删除 1 已删除

    private Date create_time;//创建时间

    private Date update_time;//最后更新时间

    private String user_id;//作者id

    private Integer categoryId = 0;//分类ID

    public Article(){}

    public Article(String name, String content, String user_id, String author){
        this.name = name;
        this.content = content;
        this.user_id = user_id;
        this.author = author;
        this.title = name;
        Calendar calendar = Calendar.getInstance();

    }
}

随后可以让前端，使用恰当的路由，来返回相应的结果

package kc.service;

import com.sun.org.apache.regexp.internal.RE;
import kc.dao.ArticleDao;
import kc.model.Article;
import kc.util.Result;
import kc.util.ResultFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class ArticleService {

    @Autowired
    ArticleDao articleDao;
    public Result insertArticle(Article article) {
        Result result = ResultFactory.giveResult(200);
        articleDao.insert(article);
        result.setMessage("success");
        return result;
    }

    public Result getById(String id){
        Result result = ResultFactory.giveResult(200);
        Article article = articleDao.selectById(id);
        result.setData(article);
        return result;
    }

    public Result getAllArticles(){
        Result result = ResultFactory.giveResult(200);
        List<Article> articleList = articleDao.allarticles();
        result.setData(articleList);
        return result;
    }
}
