博客系统是干什么的 CSDN就是一个典型的博客系统。而我在这里就是通过模拟实现一个博客系统这是一个较为简单的博客系统但是主要功能一个不缺不过就是 UI 有些 low我学习前端是为了写后端更加顺手。不至于前后端完全分离但是有个问题设计的 web 页面不是很好看。
首先我将整体的业务流程展现 我们继博客系统二继续编写到了主页的业务逻辑了
接下来的流程是通过网页端后端统一数据结构交互的数据结构。

首先在主页中需要注意的是我在这里添加了分页功能如何解决分页问题诺是将整个数据库里的文章全部读取到内存里对于内存的消耗极大所以这里我用sql语言中的 limt 语言进行分页读取不知道的可以看我Mysql的文章
通过mapper接口调用数据库
Mapper
public interface ArticleMapper {Select(select * from articleinfo order by id desc limit #{psize} offset #{offset})ListArticleinfo getListByPage(Param(pszie) int pszie,Param(offset) int offset);
}通过service层调用mapper接口
Service
public class ArticleService {Autowiredprivate ArticleMapper articleMapper;public ListArticleinfo getListByPage (int psize,int offset){return articleMapper.getListByPage(psize, offset);}
}通过Controller层调用service层方法
RestController
RequestMapping(/article)
public class ArticleController {Autowiredprivate ArticleService articleService;Resourceprivate ThreadPoolTaskExecutor taskExecutor;public ResultAjax getListByPage(Integer pindex,Integer psize) throws ExecutionException, InterruptedException {if (pindexnull||pindex1){pindex1;}if (psizenull||psize1){psize1;}Integer finalPsizepsize;int offsetpsize*(pindex-1);FutureTaskListArticleinfo listFutureTasknew FutureTask(()-{return articleService.getListByPage(finalPsize,offset);});taskExecutor.submit(listFutureTask);FutureTaskInteger sizeTasknew FutureTask(()-{int count articleService.getCount(); double sizeTemp((count*1.0)/(finalPsize*1.0));return (int)Math.ceil(sizeTemp);});taskExecutor.submit(sizeTask);ListArticleinfo articleinfoslistFutureTask.get();int sizesizeTask.get();HashMapString ,Object mapnew HashMap();map.put(list,articleinfos);map.put(szie,size);return ResultAjax.success(map);}
}解释
我在页面中每页所展示两个文章。而 limit finalPsize offset offset 我定位为 finalPsize 为第 几 行offset 显示几个数据具体原则在我的myslq 文章中有体现LIMIT [位置偏移量,] 行数使用多线程可以避开有读者写数据有读者读数据的情况。并且可以以最快速度反应的客户端这个线程池Spring提供的线程池可以不需要去设置参数。第一个线程池用来查找页面每页的内容第二个线程池用来查找文章的总数。

你会发现启动的并没有成功。原因我这里留了一个坑关于拦截器的。
Configuration
public class MyConfig implements WebMvcConfigurer {Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(new LoginIntercpet()).addPathPatterns(/**).excludePathPatterns(/css/*).excludePathPatterns(/js/*).excludePathPatterns(/css).excludePathPatterns(/img/*).excludePathPatterns(/reg.html).excludePathPatterns(/blog_list.html).excludePathPatterns(/article/detail).excludePathPatterns(/article/getlistbypage).excludePathPatterns(/user/reg).excludePathPatterns(/user/login).excludePathPatterns(/editor.md/*).excludePathPatterns(/blog_content.html).excludePathPatterns(/login.html);}
}第二个启动这里要添加mapper映射否则会失败
