我们有些文章，比如自我介绍帖子，vip课程帖子，这种区别于正常发文文章的帖子，我们可以单独管理，设计成自定义帖子模块。

新建t_post表

create table `t_post` (`id` int (11),`title` varchar (600),`content` text 
); 
insert into `t_post` (`id`, `title`, `content`) values('2','2',NULL);
insert into `t_post` (`id`, `title`, `content`) values('3','3','<p>222</p>\n');
insert into `t_post` (`id`, `title`, `content`) values('5','4测试444','<p>32324444<img alt=\"\" src=\"/articleImages/20230615120852.jpg\" style=\"height:1372px; width:720px\" /></p>\n');

用Mybatis-X生成代码；

新建PostAdminController类：

package com.python222.controller.admin;import com.python222.entity.Post;
import com.python222.service.PostService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;
import java.util.List;
import java.util.Map;/*** 管理员-自定义帖子控制器* @author python222小锋老师* @site www.python222.com*/
@RestController
@RequestMapping(value = "/admin/post")
public class PostAdminController {@Autowiredprivate PostService postService;/*** 根据条件查询自定义帖子* @return* @throws Exception*/@RequestMapping(value = "/list")public Map<String,Object> list()throws Exception{Map<String, Object> resultMap = new HashMap<>();List<Post> postList=postService.list();resultMap.put("code", 0);resultMap.put("data", postList);return resultMap;}/*** 添加或者修改自定义帖子* @param post* @return*/@RequestMapping("/save")public Map<String,Object> save(Post post){if(post.getId()==null){postService.save(post);}else{postService.updateById(post);}Map<String, Object> resultMap = new HashMap<>();resultMap.put("success", true);return resultMap;}/*** 删除自定义帖子* @param id* @return* @throws Exception*/@RequestMapping("/delete")public Map<String,Object> delete(Integer id)throws Exception{Map<String, Object> resultMap = new HashMap<>();postService.removeById(id);resultMap.put("success", true);return resultMap;}/*** 根据id查询自定义帖子实体* @param id* @return* @throws Exception*/@RequestMapping("/findById")public Map<String,Object> findById(Integer id)throws Exception{Map<String, Object> resultMap = new HashMap<>();Post post=postService.getById(id);resultMap.put("post", post);resultMap.put("success", true);return resultMap;}}

前端postManage.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>自定义帖子管理</title>
<link rel="stylesheet" href="/static/layui/css/layui.css"></link>
<link rel="stylesheet" href="/static/css/css.css"></link>
</head>
<body><div style="padding: 20px"><span class="layui-breadcrumb"><a>首页</a><a><cite>自定义帖子管理</cite></a></span><div style="padding-top: 20px;"><div><div><button class="layui-btn layuiadmin-btn-list" data-type="batchdel" onclick="addPost()">添加</button></div></div><div><table width="100%" id="postListTable" ></table></div></div>
</div><script src="/static/layui/layui.js"></script>
<script src="/static/js/jquery.js"></script>
<script src="/static/js/common.js"></script>
<script type="text/javascript">layui.use(['element','form','table'], function(){var form=layui.form;var element = layui.element; //导航的hover效果、二级菜单等功能，需要依赖element模块$ = layui.jquery; // 使用jquerytable = layui.table;table.render({elem: '#postListTable',url:'/admin/post/list',cols: [[{type:'checkbox'},{field:'id', width:100,title: '编号'},{field:'title', title: '自定义帖子名称'},{field:'action', width:300, title: '操作',align:'center',templet:formatAction}]],page: true});});function deleteOne(id){layer.confirm('您确定要删除这条记录吗？', {title:"系统提示",btn: ['确定','取消'] //按钮}, function(){layer.closeAll('dialog');$.post("/admin/post/delete",{"id":id},function(result){if(result.success){layer.msg("删除成功！");table.reload("postListTable",{});}else{layer.msg("删除失败，请联系管理员！");}},"json");}, function(){});}function addPost(){layer.open({type: 2,title: '添加自定义帖子',area: ['1000px', '730px'],content: '/admin/savePost.html' //iframe的url});}function modifyPost(id){layer.open({type: 2,title: '修改自定义帖子',area: ['1000px', '730px'],content: '/admin/savePost.html?id='+id //iframe的url});}function formatAction(d){return "<a class='layui-btn layui-btn-danger layui-btn-xs' target='_blank' href='/post/"+d.id+"'><i class='layui-icon layui-icon-read'></i>帖子预览</a><button class='layui-btn layui-btn-normal layui-btn-xs' onclick='modifyPost("+d.id+")'><i class='layui-icon layui-icon-edit'></i>编辑</button><button class='layui-btn layui-btn-warm layui-btn-xs' onclick='deleteOne("+d.id+")'><i class='layui-icon layui-icon-delete' ></i>删除</button>";}</script>
</body>
</html>

再新建一个savePost.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>添加或者修改自定义帖子</title>
<link rel="stylesheet" href="/static/layui/css/layui.css"></link>
<style type="text/css">table tr td{padding: 10px;}</style>
</head>
<body>
<div style="padding: 20px"><form method="post"><table><tr><td>标题：</td><td><input type="text" autocomplete="off" id="title" name="title" class="layui-input" style="width: 360px"/></td></tr><tr><td valign="top">内容：</td><td><textarea type="text" class="ckeditor" id="content" name="content" class="layui-input" ></textarea></td></tr><tr><td><button  class="layui-btn" onclick="submitData();return false;">提交</button></td><td><font id="errorInfo" color="red"></font></td></tr></table></form>
</div>
<script src="/static/ckeditor/ckeditor.js"></script>
<script src="/static/layui/layui.js"></script>
<script src="/static/js/jquery.js"></script>
<script src="/static/js/common.js"></script>
<script type="text/javascript">layui.use(['form'], function(){});function submitData(){var title=$("#title").val().trim();var content=CKEDITOR.instances.content.getData();if(title=="") {$("#errorInfo").text("请输入自定义帖子标题！");$("#name").focus();return false;}if(content=="") {$("#errorInfo").text("请输入自定义帖子内容！");$("#url").focus();return false;}var id=getQueryVariable("id");if(id){$.post("/admin/post/save",{id:id,title:title,content:content},function(result){if(result.success){layer.alert('修改成功！',function () {parent.reloadPage();});}else{$("#errorInfo").text(result.errorInfo);}},"json");}else{$.post("/admin/post/save",{title:title,content:content},function(result){if(result.success){layer.alert('添加成功！',function () {parent.reloadPage();});}else{$("#errorInfo").text(result.errorInfo);}},"json");}}function getQueryVariable(variable){var query = window.location.search.substring(1);var vars = query.split("&");for (var i=0;i<vars.length;i++) {var pair = vars[i].split("=");if(pair[0] == variable){return pair[1];}}return(false);}$(function(){var id=getQueryVariable("id");if(id){$.post("/admin/post/findById",{id:id},function(result){if(result.success){var post=result.post;$("#title").val(post.title);CKEDITOR.instances.content.setData(post.content);}else{layer.alert("服务器加载有问题，请联系管理员！");}},"json");}});</script>
</body>
</html>

新建PostController类：

package com.python222.controller;import com.python222.entity.Post;
import com.python222.service.PostService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;/*** 自定义帖子控制器* @author python222小锋老师* @site www.python222.com*/
@Controller
@RequestMapping("/post")
public class PostController {@Autowiredprivate PostService postService;/*** 根据id查询自定义帖子详细信息* @param id* @return* @throws Exception*/@RequestMapping("/{id}")public ModelAndView view(@PathVariable("id")Integer id)throws Exception{ModelAndView mav=new ModelAndView();Post post = postService.getById(id);mav.setViewName("post");mav.addObject("post",post);return mav;}}

前端新建模板post.html

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title th:text="${post.title}+'-'+${application.propertyMap['k1']}"></title>

<link rel="stylesheet" type="text/css" href="/static/css/normalize.css" />
<link rel="stylesheet" href="/static/css/font-awesome.min.css"></head>
<body><div class="header_top" th:include="common/head::#h" /><div class="header" th:include="common/menu::#m" /><div class="main_wrapper"><div class="w1220 article_content"><div class="title" th:text="${post.title}"></div><div class="content" th:utext="${post.content}"></div></div></div><div class="footer" th:include="common/footer::#f" /></body>
