項目代碼：https://github.com/bruceq/supermarket

項目結構：

依賴關系：

common:公共層，無依賴

dao:數據層，依賴common

service：服務層，依賴dao、common

web：應用層，依賴dao、common、service

注：啟動類在web層中

父依賴pom

web層pom依賴：

application.properties配置：

## 數據源配置spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=falsespring.datasource.username=rootspring.datasource.password=spring.datasource.driver-class-name=com.mysql.jdbc.Driver # 初始化時建立物理連接的個數spring.datasource.druid.initial-size=5# 最大連接池數量spring.datasource.druid.max-active=30# 最小連接池數量spring.datasource.druid.min-idle=5# 獲取連接時最大等待時間，單位毫秒spring.datasource.druid.max-wait=60000# 配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接，單位是毫秒spring.datasource.druid.time-between-eviction-runs-millis=60000# 連接保持空閑而不被驅逐的最小時間spring.datasource.druid.min-evictable-idle-time-millis=300000# 用來檢測連接是否有效的sql，要求是一個查詢語句spring.datasource.druid.validation-query=SELECT 1 FROM DUAL# 建議配置為true，不影響性能，并且保證安全性。申請連接的時候檢測，如果空閑時間大于timeBetweenEvictionRunsMillis，執行validationQuery檢測連接是否有效。spring.datasource.druid.test-while-idle=true# 申請連接時執行validationQuery檢測連接是否有效，做了這個配置會降低性能。spring.datasource.druid.test-on-borrow=false# 歸還連接時執行validationQuery檢測連接是否有效，做了這個配置會降低性能。spring.datasource.druid.test-on-return=false# 是否緩存preparedStatement，也就是PSCache。PSCache對支持游標的數據庫性能提升巨大，比如說oracle。在mysql下建議關閉。spring.datasource.druid.pool-prepared-statements=true# 要啟用PSCache，必須配置大于0，當大于0時，poolPreparedStatements自動觸發修改為true。spring.datasource.druid.max-pool-prepared-statement-per-connection-size=50# 配置監控統計攔截的filters，去掉后監控界面sql無法統計spring.datasource.druid.filters=stat,wall# 通過connectProperties屬性來打開mergeSql功能；慢SQL記錄spring.datasource.druid.connection-properties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500# 合并多個DruidDataSource的監控數據spring.datasource.druid.use-global-data-source-stat=true # druid連接池監控spring.datasource.druid.stat-view-servlet.login-username=adminspring.datasource.druid.stat-view-servlet.login-password=123# 排除一些靜態資源，以提高效率spring.datasource.druid.web-stat-filter.exclusions=*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/* # 端口配置server.port=8000 # mybatismybatis.type-aliases-package=com.loan.supermarket.mappermybatis.mapper-locations=classpath:mapping/*.xmlmybatis.configuration.map-underscore-to-camel-case=true # THYMELEAF (ThymeleafAutoConfiguration)spring.thymeleaf.prefix=classpath:/templates/spring.thymeleaf.suffix=.htmlspring.thymeleaf.mode=HTML5spring.thymeleaf.encoding=UTF-8# ;charset=<encoding> is added#spring.thymeleaf.content-type=text/html# set to false for hot refreshspring.thymeleaf.cache=false

前42行是對druid的基礎配置，包括基礎數據源配置，以及druid的基礎參數；

47~50行是mybatis中對于mapper的xml的配置，便于項目啟動后掃描到xml的相關文件，xml內寫的是項目相關的sql。

45行指默認項目啟動默認端口為8000。

52行~60行是thymeleaf的基礎配置，thymeleaf是一種常見的模板引擎，相當于jsp這樣的前臺代碼。

為了實現簡單的登錄功能，我們在controller中定義一些接口方法：

package com.loan.supermarket.web.controller; import com.google.code.kaptcha.impl.DefaultKaptcha;import com.loan.supermarket.mapper.JsonObject;import com.loan.supermarket.mapper.User;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.PostMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.servlet.ModelAndView;import org.thymeleaf.util.StringUtils; import javax.imageio.ImageIO;import javax.servlet.ServletOutputStream;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.http.HttpSession;import java.awt.image.BufferedImage;import java.io.ByteArrayOutputStream;import java.util.ArrayList;import java.util.Date; @Controllerpublic class TemplateController { @RequestMapping('/index') public String index(Model model) { User user = new User(); user.setName('張三'); user.setId(1L); user.setTelephone('123456789'); user.setPassword('@#$%^&*()'); user.setRegisterTime(new Date()); user.setPopedom(1); User user1 = new User(); user1.setName('李四'); user1.setId(2L); user1.setTelephone('2222222'); user1.setPassword('最近是南風天'); user1.setRegisterTime(new Date()); user1.setPopedom(1); User user2 = new User(); user2.setName('王五'); user2.setId(3L); user2.setTelephone('33333333333'); user2.setPassword('妖姬'); user2.setRegisterTime(new Date()); user2.setPopedom(1); User user3 = new User(); user3.setName('趙六'); user3.setId(4L); user3.setTelephone('33333333333'); user3.setPassword('過河卒'); user3.setRegisterTime(new Date()); user3.setPopedom(0); ArrayList<User> list = new ArrayList<User>(); list.add(user); list.add(user1); list.add(user2); list.add(user3); model.addAttribute('users', list); return 'index'; } @RequestMapping('/login') public String login1() { return 'login'; } @PostMapping('/user_login') @ResponseBody public JsonObject<String> login(String username, String password, HttpServletRequest request) { JsonObject<String> obj = new JsonObject<String>(); HttpSession session = request.getSession(); if (!StringUtils.isEmpty(username) && !StringUtils.isEmpty(password)) { obj.setCode('0'); User user = new User(); user.setName(username); session.setAttribute('loginUser', user); return obj; } obj.setCode('1'); obj.setMessage('用戶名或密碼錯誤'); return obj; } @Autowired private DefaultKaptcha captchaProducer; /** * 獲取驗證碼的請求路徑 * @param httpServletRequest * @param httpServletResponse * @throws Exception */ @RequestMapping('/defaultKaptcha') public void defaultKaptcha(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception{ byte[] captchaChallengeAsJpeg = null; ByteArrayOutputStream jpegOutputStream = new ByteArrayOutputStream(); try { //生產驗證碼字符串并保存到session中 String createText = captchaProducer.createText(); httpServletRequest.getSession().setAttribute('vrifyCode', createText); //使用生產的驗證碼字符串返回一個BufferedImage對象并轉為byte寫入到byte數組中 BufferedImage challenge = captchaProducer.createImage(createText); ImageIO.write(challenge, 'jpg', jpegOutputStream); } catch (IllegalArgumentException e) { httpServletResponse.sendError(HttpServletResponse.SC_NOT_FOUND); return; } //定義response輸出類型為image/jpeg類型，使用response輸出流輸出圖片的byte數組 captchaChallengeAsJpeg = jpegOutputStream.toByteArray(); httpServletResponse.setHeader('Cache-Control', 'no-store'); httpServletResponse.setHeader('Pragma', 'no-cache'); httpServletResponse.setDateHeader('Expires', 0); httpServletResponse.setContentType('image/jpeg'); ServletOutputStream responseOutputStream =httpServletResponse.getOutputStream(); responseOutputStream.write(captchaChallengeAsJpeg); responseOutputStream.flush(); responseOutputStream.close(); } /** * 驗證的方法 * @param httpServletRequest * @param httpServletResponse * @return */ @RequestMapping('/imgvrifyControllerDefaultKaptcha') public ModelAndView imgvrifyControllerDefaultKaptcha(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse){ ModelAndView andView = new ModelAndView(); String captchaId = (String) httpServletRequest.getSession().getAttribute('vrifyCode'); String parameter = httpServletRequest.getParameter('vrifyCode'); System.out.println('Session vrifyCode '+captchaId+' form vrifyCode '+parameter); if (!captchaId.equals(parameter)) { andView.addObject('info', '錯誤的驗證碼'); andView.setViewName('index'); } else { andView.addObject('info', '登錄成功'); andView.setViewName('success'); } return andView; }}

搭配前臺的代碼一起分析：

在項目啟動后，訪問http://localhost:8000/login，進入到登錄頁面，首先加載必要的css和js資源，在填寫好用戶名、密碼后，點擊登錄，會執行user_login的接口方法，簡單的對用戶進行校驗，即可進入首頁。

其次要說的是這個項目中，添加了驗證碼的功能，使用了kaptcha的依賴。在登錄界面中，增加了驗證碼的顯示，點擊驗證碼圖片后，可以切換驗證碼。
