3.登入表单
<form th:action="@{/code}" method="post">
<div class="inputBox">
<input type="text" placeholder="账户ID" name="username" id="name" required onblur="a1()" onkeyup="this.value=this.value.replace(/\s+/g,'')">

</div>
<div class="inputBox">
<input type="submit" value="登录">
</div>
<p class="forget">忘记密码?<a href="#">
点击这里
</a></p>
<p class="forget">没有账户?<a href="#">
注册
</a></p>
</form>
4. 添加配置类 SecurityConfig
package com.jsxs.kumquat.config;
import com.jsxs.kumquat.service.impl.CkqnUserServiceImpl;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;
import javax.annotation.Resource;
/**

* @PackageName:com.jsxs.kumquat.config
* @ClassName: SecurityConfig
* @Description: TODO 授权文件
* @Version 1.0
*/
@EnableWebSecurity
@Configuration
@Component
public class SecurityConfig extends WebSecurityConfigurerAdapter {
// 调用的是业务实现类
@Resource
private CkqnUserServiceImpl ckqnUserService;
// 密码加密方式
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
/**
* 认证
*
* @param http
* @throws Exception permitAll -> 无条件访问
* authenticated -> 需要认证才能访问, /* 除了无条件的，其他都加上锁
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
// 首页所有人可以访问，但是功能页只有对应有权限的人才能访问
http.authorizeRequests()
.antMatchers("/", "/index.html", "/login.html", "/mainMenu.html", "/JsxsRoad.html", "/recommendedArticles.html", "/code", "/a3").permitAll()
.antMatchers("/*").authenticated();
super.configure(http);
http.formLogin().loginPage("/login.html");
// 登录配置
http.formLogin()
.usernameParameter("username") // 这个参数必须为username (约定大于配置)
.passwordParameter("password") // 这个参数必须为password (约定大于配置)
.loginPage("/login.html") //登入页面是哪个?
.loginProcessingUrl("/code") // 点击提交的时候跳转到哪里?
.defaultSuccessUrl("/"); // 密码验证通过后我们跳转到哪里?
// 注销配置
http.headers().contentTypeOptions().disable();
http.headers().frameOptions().disable(); // 图片跨域
http.csrf().disable();//关闭csrf功能:跨站请求伪造,默认只能通过post方式提交logout请求(ajax如果要使用一定开启)
http.logout().logoutSuccessUrl("/");
}
/**
*
* @param auth
* @throws Exception userDetailsService-》对哪个业务进行操作，passwordEncoder-》密码加密方式
*/
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(ckqnUserService).passwordEncoder(passwordEncoder());
}
/**
*
* @param web
* @throws Exception 对静态资源不拦截: static目录可以省略
*/
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers("/css/**", "/assets/**", "/plugins/**", "/img/**", "/editor.md/**", "/Jquery/**", "/layui/**", "/qrcode/**");
}
}
5.接口实现类 CkqnUserServiceImpl
CkqnUserServiceImpl
package com.jsxs.kumquat.service.impl;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.jsxs.kumquat.pojo.CkqnUser;
import com.jsxs.kumquat.mapper.CkqnUserMapper;
import com.jsxs.kumquat.pojo.CkqnUserRole;
import com.jsxs.kumquat.service.CkqnUserRoleService;
import com.jsxs.kumquat.service.CkqnUserService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import javax.servlet.http.HttpSession;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
/**
* <p>
* 服务实现类
* </p>
*
* @author 吉士先生
* @since 2023-04-09
* TODO 这里需要继承一个接口: UserDetailsService
*/
@Service
public class CkqnUserServiceImpl extends ServiceImpl<CkqnUserMapper, CkqnUser> implements CkqnUserService, UserDetailsService {
// 1. 业务层接口
@Resource
CkqnUserService userService;
// 2. 认证角色层接口
@Resource
CkqnUserRoleService roleService;
// 3.session
@Resource
HttpSession session;
/**
* TODO 用户逻辑和认证
*
* @param uid
* @return
* @throws UsernameNotFoundException
*/
@Override
public UserDetails loadUserByUsername(String uid) throws UsernameNotFoundException {
// 4. 通过用户名查询用户
CkqnUser user = userService.getOne(new QueryWrapper<CkqnUser>().eq("uid", uid));
// 5. 查询到的角色放入session
session.setAttribute("loginUser", user);
// 7.创建一个新的UserDetails对象，最后验证登陆的需要
UserDetails userDetails = null;
if (user != null) {
System.out.println("未加密：" + user.getPassword());
// 8.加密密码
String BCryptPassword = new BCryptPasswordEncoder().encode(user.getPassword());
// 登录后会将登录密码进行加密，然后比对数据库中的密码，数据库密码需要加密存储！
// String password = user.getPassword();
// 9. 创建一个集合来存放权限
Collection<GrantedAuthority> authorities = getAuthorities(user);
/**
* TODO 实例化UserDetails对象
* uid-> 前端username框传过来的数据
* BCryptPassword-> 加密后的密码
* authorities -》 认证列表
*/
userDetails = new org.springframework.security.core.userdetails.User(uid, BCryptPassword,
true,
true,
true,
true, authorities);
}
return userDetails;
}
/**
* @param user ->实体类
* @return
*/
private Collection<GrantedAuthority> getAuthorities(CkqnUser user) {
List<GrantedAuthority> authList = new ArrayList<GrantedAuthority>();
// 1. 通过用户的第三个字段roleID再另一个表中查找数据据
CkqnUserRole role = roleService.getById(user.getRoleId());
// 2. 注意：这里每个权限前面都要加ROLE_。否在最后验证不会通过
authList.add(new SimpleGrantedAuthority("ROLE_" + role.getName()));
return authList;
}
}
两张表
6.前端认证问题
xmlns:sec="http://www.thymeleaf.org/extras/spring-security"
sec:authorize="!isAuthenticated()" 没有被认证就是显示
sec:authorize="isAuthenticated()" 认证了才被显示
(二)、SpringBoot整合Ajax
1.登入表单
<form th:action="@{/code}" method="post">
<div class="inputBox">
<input type="text" placeholder="账户ID" name="username" id="name" required onblur="a1()" onkeyup="this.value=this.value.replace(/\s+/g,'')">
<--*******id 为username, 上面id为name-->
<i id="username" style="z-index: 9999"></i>
</div>
<div class="inputBox">
<input type="password" placeholder="密码" name="password" required onkeyup="this.value=this.value.replace(/\s+/g,'')">
</div>
<div class="inputBox">
<input type="submit" value="登录">
</div>
<p class="forget">忘记密码?<a href="#">
点击这里
</a></p>
<p class="forget">没有账户?<a href="#">
注册
</a></p>
</form>
2. JavaScript
// AJAX -js
<script src="Jquery/jquery-3.6.1.js"></script>
function a1(){
$.post({
url:"http://localhost:8080/a3",
data:{
'name':$("#name").val()},
success:function(data){
if(data.toString()=='OK'){
$("#username").css("color","green");
}else{
$("#username").css("color","red");
}
$("#username").html(data);
}
});
}
function a2(){
$.post({
url: "http://localhost:8080/a3",
data: {
'pwd': $("#pwd").val()},
success: function (data) {
if (data.toString()=='OK') {
$("#userpwd").css("color", "green");
} else {
$("#userpwd").css("color", "red");
}
$("#userpwd").html(data);
}
});
}
(三)、SpringBoot整合editor.md
前提需要我们导入editor.md的插件文件
1.编写页面
(1).前端页面
引入文件
<link rel="stylesheet" href="{/editor.md/examples/css/style.css" th:href="@{/editor.md/examples/css/style.css/}">
<link rel="stylesheet" href="/editor.md/css/editormd.css" th:href="@{/editor.md/css/editormd.css}"/>
<link rel="shortcut icon" href="https://pandao.github.io/editor.md/favicon.ico" type="image/x-icon"/>
<script src="Jquery/jquery-3.6.1.js"></script>
在这里编写文件
<div id="test-editormd">
<textarea style="display:none;" name="content"></textarea>
</div>
配置JS
<script src="/editor.md/examplesjs/jquery.min.js" th:src="@{/editor.md/examples/js/jquery.min.js}"></script>
<script src="/editor.md/editormd.js" th:src="@{/editor.md/editormd.js}"></script>
<script type="text/javascript">
var testEditor;
$(function () {
$.get('/editor.md/examples/test.md', function (md) {
// 这里的第一个参数,指的是:"编写页面的id": 第二个参数是: "配置"
testEditor = editormd("test-editormd", {
width: "100%", // 1.宽度
height: "750px", // 2.高度
path: '/editor.md/lib/', //3.配置文件
theme: "dark", //4.主题
markdown:'#欢迎您来到金橘社区!!', //5.默认编辑页面
// previewTheme: "dark",
editorTheme: "pastel-on-dark", // 6.编辑页面主题
imageUpload: true, //7.文件上传
imageFormats: ["jpg", "jpeg", "gif", "png", "bmp", "webp"],
imageUploadURL: "/article/image/upload", //8.图片上传URL
toolbarIcons: function () {
//9.组件
return ["undo", "redo", "|", "bold", "del", "italic", "quote", "ucwords", "uppercase", "lowercase", "|", "h1", "h2", "h3", "h4", "h5", "h6", "|", "list-ul", "list-ol", "hr", "|", "link", "reference-link", "image", "code", "preformatted-text", "code-block", "table", "datetime", "emoji", "html-entities", "pagebreak", "|", "goto-line", "watch", "preview", "fullscreen", "clear", "search", "|", "help", "info", "||", "publish"];
},
toolbarIconTexts: {
//10.自定义发布按钮的组件
publish: "<span bgcolor='gray' style='font-family: 微软雅黑;font-weight: bold;color: #00FF00'>发布</span>"
},
toolbarHandlers: {
//11. 提交文章上传的路径
publish: function (cm, icon, cursor, selection) {
mdEditorForm.method = "post";
mdEditorForm.action = "/article/publish";//提交至服务器的路径
mdEditorForm.submit();
}
}
});
});
});
</script>

以上可以实现异步登入判断
(三)、知识点新发现
1. template包中创建包静态资源路径一样.
2. SpringBoot自定义400、500错误。只需要在template包下创建error包即可。
3. 加入我们要使用mybatis-plus那么条件构造其实际上就是对SQL的拼接操作。构造器的泛型是: 实体类
//1. 通过账户UserUid进行查找用户
@RequestMapping("/code")
public String SelectByUserUid(){
// 1.定义条件构造器-> 这里的泛型是实体类
QueryWrapper<CkqnUser> wrapper = new QueryWrapper<>();
wrapper.eq("uid","root");
CkqnUser one = ckqnUserService.getOne(wrapper.eq("uid", "root"));
return ""+one;
}
4.我们在验证登入操作的时候，只需要根据username进行判断即可，因为这样可以减少对数据库的一次访问
//1. 通过账户UserUid进行查找用户 -> 可以减少对数据库的访问频次(可以减少对密码的查询)
@PostMapping("/code")
public String SelectByUserUid() throws Exception {
// 1.定义条件构造器-> 这里的泛型是实体类
QueryWrapper<CkqnUser> wrapper = new QueryWrapper<>();
// 2.添加条件: 是否相等
wrapper.eq("uid","root");
// 3.执行查找数据的操作
CkqnUser ckqnUser = ckqnUserService.getOne(wrapper.eq("uid", "root"));
// 4.optional检测是否为空
Optional<CkqnUser> optional = Optional.ofNullable(ckqnUser);
// 5.假如为空直接抛出异常
optional.orElseThrow(()->new Exception("非常抱歉出现了空指针异常!!"));
// 6.查看密码
String password = ckqnUser.getPassword();
CkqnUser ckqnUser1 = ckqnUserService.getOne(wrapper.eq("password", password));
if (ckqnUser1.equals(ckqnUser)){
return "index";
}else {
return "login";
}
(四)、金橘社区前端设计

1. 渐变动态背景CSS .
<style>
body {
margin: 0;
padding: 0;
height: 100vh;
display: flex;
justify-content: center;
align-items: center;
background: linear-gradient(135deg, #34ac40, #2c8ae8, #dc47cd, #e7e373);
background-size: 500%;
animation: bgAnimation 6s linear infinite;
}
h1 {
color: white;
letter-spacing: 5px;
}
@keyframes bgAnimation {
0% {
background-position: 0% 50%;
}
50% {
background-position: 100% 50%;
}
100% {
background-position: 0% 50%;
}
}
</style>
2. sleep() 休眠的工具类
function sleep(numberMillis) {
var now = new Date();
var exitTime = now.getTime() + numberMillis;
while (true) {
now = new Date();
if (now.getTime() > exitTime)
return true;
}
}
3. 利用JS页面的跳转,我们一定要用异步跳转
// 这里一定要异步对其进行跳转页面
setTimeout(()=>{
document.location.href="two.html"
},600)

9. 前端引入 markdown编辑器 ---- 一定要和html处于同级目录下.
[Editor.md - 开源在线 Markdown 编辑器 (pandao.github.io)](https://pandao.github.io/editor.md/)
首先我们必须先要打开上面的网站: 然后点击安装下载: 就会跳转到一个Github项目中。安装一个压缩包
然后解压到我们的项目中:
<link rel="stylesheet" href="editor.md/css/editormd.min.css">
<script src="https://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
<script src="editor.md/lib/marked.min.js"></script>
<script src="editor.md/lib/prettify.min.js"></script>
<script src="editor.md/editormd.js"></script>
<!-- 正文: -->
<div id="editor">
</div>
<script>
var editor = editormd("editor", {
// 这里的尺寸必须在这里设置，设置样式会被 editormd 自动覆盖
width: "100%",
// 设置高度
height: "500px",
// 编辑器中初始内容
markdown: "# 在这里写下一篇博客",
// 指定插件路径
path: "editor.md/lib/"
});
</script>

12. 文本框不能为空格的属性,一个属性就可以
οnkeyup="this.value=this.value.replace(/\s+/g,'')"
