 更新時(shí)間：2022年03月22日 08:30:29   作者：程序員小徐同學(xué)  
這篇文章主要介紹了SpringBoot整合Thymeleaf小項(xiàng)目,本項(xiàng)目使用SpringBoot開發(fā)，jdbc5.1.48，主要涉及到Mybatis的使用，Thymeleaf的使用，用戶密碼加密，驗(yàn)證碼的設(shè)計(jì)，圖片的文件上傳（本文件上傳到本地，沒有傳到數(shù)據(jù)庫）登錄過濾，需要的朋友可以參考下

1.項(xiàng)目簡紹

本項(xiàng)目使用SpringBoot開發(fā)，jdbc5.1.48 Mybatis 源碼可下載

其中涉及功能有：Mybatis的使用，Thymeleaf的使用，用戶密碼加密，驗(yàn)證碼的設(shè)計(jì)，圖片的文件上傳（本文件上傳到本地，沒有傳到數(shù)據(jù)庫）登錄過濾等

用戶數(shù)據(jù)庫

在這里插入圖片描述

員工數(shù)據(jù)庫設(shè)計(jì)

在這里插入圖片描述

基本的增刪改查都有

## 項(xiàng)目說明
本項(xiàng)目使用SpringBoot開發(fā)，jdbc5.1.48
### 1.數(shù)據(jù)庫信息
創(chuàng)建兩個(gè)表，管理員表user和員工表employee
### 2.項(xiàng)目流程
1.springboot集成thymeleaf
	1).引入依賴
		<!--使用thymelaf-->
		<dependency>
		  <groupId>org.springframework.boot</groupId>
		  <artifactId>spring-boot-starter-thymeleaf</artifactId>
		</dependency>
	
	2).配置thymeleaf模板配置
		spring:
		  thymeleaf:
		    cache: false  # 關(guān)閉緩存
		    prefix: classpath:/templates/ #指定模板位置
		    suffix: .html #指定后綴
	3).開發(fā)controller跳轉(zhuǎn)到thymeleaf模板
		@Controller
		@RequestMapping("hello")
		public class HelloController {
		    @RequestMapping("hello")
		    public String hello(){
		        System.out.println("hello ok");
		        return "index";  // templates/index.html
		    }
		}
=================================================================
2.thymeleaf 語法使用
	1).html使用thymeleaf語法 必須導(dǎo)入thymeleaf的頭才能使用相關(guān)語法
		namespace: 命名空間  
		<html lang="en" xmlns:th="http://www.thymeleaf.org">
	2).在html中通過thymeleaf語法獲取數(shù)據(jù)
================================================================
###3.案例開發(fā)流程
?	
	需求分析: 分析這個(gè)項(xiàng)目含有哪些功能模塊
		用戶模塊:
			注冊(cè)
			登錄
			驗(yàn)證碼
			安全退出
			真是用戶
		員工模塊:
			添加員工+上傳頭像
			展示員工列表+展示員工頭像
			刪除員工信息+刪除員工頭像
			更新員工信息+更新員工頭像
	庫表設(shè)計(jì)(概要設(shè)計(jì)): 1.分析系統(tǒng)有哪些表  2.分析表與表關(guān)系  3.確定表中字段(顯性字段 隱性字段(業(yè)務(wù)字段))
		2張表 
			1.用戶表 user
				id username realname password gender
			2.員工表 employee
				id name salary birthday  photo
		創(chuàng)建一個(gè)庫: ems-thymeleaf
	詳細(xì)設(shè)計(jì):
		省略
	編碼(環(huán)境搭建+業(yè)務(wù)代碼開發(fā))
		1.創(chuàng)建一個(gè)springboot項(xiàng)目 項(xiàng)目名字: ems-thymeleaf
		2.修改配置文件為 application.yml  pom.xml  2.5.0
		3.修改端口   項(xiàng)目名: ems-thymeleaf
		4.springboot整合thymeleaf使用
			a.引入依賴
			b.配置文件中指定thymeleaf相關(guān)配置
			c.編寫控制器測(cè)試
		5.springboot整合mybatis
				mysql、druid、mybatis-springboot-stater
			b.配置文件中 
		6.導(dǎo)入項(xiàng)目頁面
			static  存放靜態(tài)資源
			templates 目錄 存放模板文件
	測(cè)試
	上線部署
	維護(hù)
	發(fā)版
======================================================================

        if (file.exists()) file.delete();
        return "redirect:/employee/lists";//跳轉(zhuǎn)到員工列表
}

4.前端控制配置類

package com.xuda.springboot.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
/**
 * @author ：程序員徐大大
 * @description：TODO
 * @date ：2022-03-20 20:49
 */
@Configuration
public class MvcConfig implements WebMvcConfigurer {
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("redirect:/login");
        registry.addViewController("login").setViewName("login");
        registry.addViewController("login.html").setViewName("login");
        registry.addViewController("register").setViewName("regist");
        registry.addViewController("addEmp").setViewName("addEmp");
    }
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new LoginHandlerInterceptor()).addPathPatterns("/**")
                .excludePathPatterns("/register","/user/login","/css/**","/js/**","/img/**","/user/register","/login","/login.html");
}

5.過濾器

package com.xuda.springboot.config;

import com.xuda.springboot.controller.UserController;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
 * @author ：程序員徐大大
 * @description：TODO
 * @date ：2022-03-21 20:17
 */
@Configuration
public class LoginHandlerInterceptor implements HandlerInterceptor {
    private static final Logger log = LoggerFactory.getLogger(LoginHandlerInterceptor.class);
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
       log.info("session+=》{}",request.getSession().getAttribute("user"));
        //登錄成功后，應(yīng)該有用戶得session
        Object loginuser = request.getSession().getAttribute("user");
        if (loginuser == null) {
            request.setAttribute("loginmsg", "沒有權(quán)限請(qǐng)先登錄");
            request.getRequestDispatcher("/login.html").forward(request, response);
            return false;
        } else {
        return true;
        }
    }
}

6.yml配置
