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

    import javax.servlet.http.HttpServletRequest;

    import cn.itsource.domain.Article;
    import cn.itsource.query.IArticleQuery;
    import cn.itsource.util.PageBase;

    public interface IArtService {
    PageBase<Article> findall(IArticleQuery query);
    void del(Long id,HttpServletRequest req);
    Map<String, List<Article>> findArticle();
    void save(Article article,HttpServletRequest req);
    void delete(Long id);
    Article updateClick(String url);
    }

    文章管理页面处理器调用的抽象类的实现

    package cn.itsource.service.impl;

    import java.io.File;
    import java.util.HashMap;
    import java.util.List;
    import java.util.Map;

    import javax.servlet.http.HttpServletRequest;

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

    import cn.itsource.domain.Article;
    import cn.itsource.domain.ArticleType;
    import cn.itsource.mapper.Articlemapper;
    import cn.itsource.mapper.Artictypelemapper;
    import cn.itsource.query.IArticleQuery;
    import cn.itsource.service.IArtService;
    import cn.itsource.util.Constant;
    import cn.itsource.util.FreeMarkerUtil;
    import cn.itsource.util.PageBase;
    @Service
    public class ArtServiceimpl implements IArtService{

    @Autowired
    private Articlemapper mapper;
    @Autowired
    private Artictypelemapper typemapper;

    /*查询*/
    @Override
    public PageBase<Article> findall(IArticleQuery query) {
    /*查询文章总数量: 根据高级查询拿三个条件来决定*/
    Integer totalsCount = mapper.findTotalCount(query);
    /*按照分页条件查数据: 高级查询三条件加入进来*/
    List<Article> list = mapper.findAll(query);
    /*给每一个article对象的type属性赋值*/
    for (Article article : list) {
    Long id = article.getTypeId();
    ArticleType type = typemapper.findbyid(id);
    //System.out.println(type);
    article.setType(type);
    }
    PageBase<Article> li = new PageBase<>(list, totalsCount);

    return li;
    }

    /*删除*/
    @Override
    public void delete(Long id) {
    System.out.println("文章管理执行了删除操作");
    mapper.delete(id);
    }

    /*前台文章分栏查询*/
    @Override
    public Map<String, List<Article>> findArticle() {
    Map<String, List<Article>> map= new HashMap<>();
    /*查询技术文章*/
    List<Article> technologys = mapper.findArticleByCode(Constant.TECHNOLOGY);
    /*查询行业新闻*/
    List<Article> industrys = mapper.findArticleByCode(Constant.INDUSTRY);
    /*查询学科咨询*/
    List<Article> subjects = mapper.findArticleByCode(Constant.SUBJECT);
    map.put("technologys", technologys);
    map.put("industrys", industrys);
    map.put("subjects", subjects);
    return map;
    }

    /*添加*/
    @Override
    public void save(Article article, HttpServletRequest req) {
    String realPath = req.getServletContext().getRealPath("/static/template");
    File file = new File(realPath);
    if(!file.exists()){//如果文件夹不存在,就创建文件夹
    file.mkdirs();
    }
    String url = FreeMarkerUtil.createFile(realPath, "article.ftl", article, ".html");
    article.setUrl("/static/template/"+url);
    if(article.getId()!=null){
    Article oldArticle = mapper.findById(article.getId());//得到了数据库中旧的那条数据
    String oldUrl = oldArticle.getUrl();// /static/template/1605176075312.html
    //F:/workspace/PojOneSpace/Day47_cms03/src/main/webapp+
    String real = req.getServletContext().getRealPath("/");
    new File(real,oldUrl).delete();//删除旧的文件
    mapper.update(article);
    }else{
    mapper.add(article);
    }
    }

    /*删除*/
    @Override
    public void del(Long id, HttpServletRequest req) {
    Article article = mapper.findOne(id);
    mapper.del(id);
    String realPath = req.getServletContext().getRealPath("/");
    new File(realPath, article.getUrl()).delete();

    }

    /*点击次数处理*/
    @Override
    public Article updateClick(String oldurl) {
    System.out.println(oldurl);
    String url="/static/template/"+oldurl;
    Article article = mapper.findByURL(url);
    article.setClickCount(article.getClickCount()+1);
    /*把数据库的点击数也要修改并且回显*/
    mapper.update(article);
    System.out.println(article);
    return article;
    }
    }

    文章管理实现类会调用的mapper

    package cn.itsource.mapper;

    import java.util.List;

    import cn.itsource.domain.Article;
    import cn.itsource.query.IArticleQuery;

    public interface Articlemapper {
    List<Article> findAll(IArticleQuery query);
    Integer findTotalCount(IArticleQuery query);
    void delete(Long id);
    List<Article> findArticleByCode(String constant);
    void add(Article article);
    void update(Article article);
    Article findOne(Long id);
    void del(Long id);
    Article findById(Long id);
    Article findByURL(String url);
    }

    文章管理mapper映射文件

    |--common【后台共用页面】
    上传的图片:
    |--upload【后台轮播图上传 -- 上传图片】
    |--ueditor【后台管理页面 -- 富文本上传的图片默认上传到这里】
    静态资源:
    |--static【前台和后台所有的静态资源】
    |--home【前台首页 -- 静态资源js,css,img】
    |--system【后台管理页面 -- 静态资源css,fonts,js,images】
    |--gridmanager【后台数据列表用到的插件资源 -- css,js】
