大家好，我是雄雄，欢迎关注微信公众号【雄雄的小课堂】。

前言

书接前文，昨天带着大家下载且配置了maven，以及在idea中创建maven项目，今天，我们就结合ssm框架，在idea中实现一个增删改查案例。

昨天的文章：手把手教你搭建Maven项目

01

配置pom文件

通常，我们需要使用ssm框架的时候，需要加载一系列的jar包，在未使用maven的时候，我们则采用的是将所需jar包统统复制到项目的lib目录中，现在我们不必那样做了，只需要简单的在pom文件中配置即可。

那么，怎么配置呢？

我们以mysql的驱动jar为例（其他jar包配置方式一样，可执行按此配置），mysql的驱动jar包我采用的是：mysql-connector-java-8.0.23，配置方式如下：

1）maven官网为我们提供了jar包在pom文件中的配置方式，打开官网：/，我们在输入框中输入需要配置的jar包名，如下：

可以在左边框中的下拉列表里选择版本，在右边的Apache Maven下面，复制所有代码。

复制到项目中pom文件的这里：

如果你不知道ssm需要哪些jar包，可以去百度搜索，pom中配置方式是一样的，在这就不一一列举了，下面是整个pom.xml文件的代码：

<?xml version="1.0"encoding="UTF-8"?><projectxmlns="/POM/4.0.0"xmlns:xsi="/2001/XMLSchema-instance"xsi:schemaLocation="/POM/4.0.0 /xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.xiongxiong</groupId><artifactId>BookManageSys</artifactId><version>1.0-SNAPSHOT</version><packaging>war</packaging><name>BookManageSys Maven Webapp</name><url></url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><piler.source>1.7</piler.source><piler.target>1.7</piler.target></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.23</version></dependency><dependency><groupId>javaee</groupId><artifactId>javaee-api</artifactId><version>5</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>4.2.5.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>4.2.2.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>4.2.2.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>4.1.9.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>4.2.1.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>4.1.9.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>4.2.3.release</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>4.1.9.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>4.2.3.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.1.9.RELEASE</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.2.2</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.0</version></dependency><dependency><groupId>org.javassist</groupId><artifactId>javassist</artifactId><version>3.17.1-GA</version></dependency><dependency><groupId>cglib</groupId><artifactId>cglib</artifactId><version>2.2.2</version></dependency><dependency><groupId>c3p0</groupId><artifactId>c3p0</artifactId><version>0.9.1.2</version></dependency><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency></dependencies><build><finalName>BookManageSys</finalName><pluginManagement><plugins><plugin><artifactId>maven-clean-plugin</artifactId><version>3.1.0</version></plugin><plugin><artifactId>maven-resources-plugin</artifactId><version>3.0.2</version></plugin><plugin><artifactId>maven-compiler-plugin</artifactId><version>3.8.0</version></plugin><plugin><artifactId>maven-surefire-plugin</artifactId><version>2.22.1</version></plugin><plugin><artifactId>maven-war-plugin</artifactId><version>3.2.2</version></plugin><plugin><artifactId>maven-install-plugin</artifactId><version>2.5.2</version></plugin><plugin><artifactId>maven-deploy-plugin</artifactId><version>2.8.2</version></plugin></plugins></pluginManagement></build></project>

这是最后导入的jar包：

02

在main目录中创建resources资源文件夹

该资源文件夹用来存放ssm的配置文件，applicationContext.xml,springmvc-servlet.xml,mybatis-config.xml。

各配置文件代码如下：

applicationContext.xml文件：

<?xml version="1.0"encoding="UTF-8"?><beansxmlns="/schema/beans"xmlns:xsi="/2001/XMLSchema-instance"xmlns:mvc="/schema/mvc"xmlns:context="/schema/context"xsi:schemaLocation="/schema/beans /schema/beans/spring-beans-3.1.xsd/schema/mvc /schema/mvc/spring-mvc-3.1.xsd/schema/context /schema/context/spring-context-3.1.xsd"><beanid="dataSource"class="org.springframework.jdbc.datasource.DriverManagerDataSource"><propertyname="driverClassName"value="com.mysql.jdbc.Driver"></property><propertyname="url"value="jdbc:mysql://localhost:3306/schooldb"></property><propertyname="username"value="root"></property><propertyname="password"value="root"></property></bean><beanid="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean"><propertyname="dataSource"ref="dataSource"></property><propertyname="configLocation"value="classpath:mybatis-config.xml"></property><propertyname="mapperLocations"><list><value>classpath:com/dao/*.xml</value></list></property></bean><beanclass="org.mybatis.spring.mapper.MapperScannerConfigurer"><propertyname="basePackage"value="com.dao"></property></bean><context:component-scanbase-package="com.dao,com.service,com.web"/><mvc:annotation-driven/></beans>

springmvc-servlet.xml文件：

<?xml version="1.0"encoding="UTF-8"?><beansxmlns="/schema/beans"xmlns:xsi="/2001/XMLSchema-instance"xmlns:p="/schema/p"xmlns:aop="/schema/aop"xmlns:mvc="/schema/mvc"xmlns:context="/schema/context"xsi:schemaLocation="/schema/beans /schema/beans/spring-beans-3.1.xsd/schema/p /schema/p/spring-p-3.1.xsd/schema/aop /schema/aop/spring-aop-3.1.xsd/schema/mvc /schema/mvc/spring-mvc-3.1.xsd/schema/context /schema/context/spring-context-3.1.xsd"><context:component-scanbase-package="com.web,com.dao,com.service"/><mvc:annotation-driven/><mvc:default-servlet-handler/><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><propertyname="prefix"value="/"></property><propertyname="suffix"value=".jsp"></property></bean></beans>

mybatis-config.xml文件：

<?xml version="1.0"encoding="UTF-8"?><!DOCTYPE configurationPUBLIC "-////DTD Config 3.0//EN""/dtd/mybatis-3-config.dtd"><configuration><settings><settingname="logImpl"value="STDOUT_LOGGING"/></settings><typeAliases><packagename="com.entity"/></typeAliases></configuration>

03

配置web.xml文件

web.xml文件所在的路径：src/main/webapp/WEB/INF/wen.xml

代码如下：

<!DOCTYPE web-app PUBLIC"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN""/dtd/web-app_2_3.dtd" ><web-appxmlns="/xml/ns/javaee"xmlns:xsi="/2001/XMLSchema-instance"xsi:schemaLocation="/xml/ns/javaee /xml/ns/javaee/web-app_4_0.xsd"version="4.0"><display-name>Archetype Created Web Application</display-name><welcome-file-list><welcome-file>/</welcome-file></welcome-file-list><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc-servlet.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>

04

创建src资源资源文件夹

在main文件夹中创建资源文件夹src,且在里面创建实体层、Dao层、Service层和web层。

下面我们来在src中创建包com（包名随便起）,在com中分别创建entity、dao、service以及web包（Package）,分别在各个包中创建对应的类，其目录结构如下：

下面是各个类的代码：

BookManage.java：

packagecom.entity;importorg.springframework.format.annotation.DateTimeFormat;importjava.util.Date;publicclassBookManage{privateintbid;privateString bname;privateString bauthor;@DateTimeFormat(pattern = "yyyy-MM-dd")privateDate btime;privateintbtype;publicintgetBid(){returnbid;}publicvoidsetBid(intbid){this.bid = bid;}publicString getBname(){returnbname;}publicvoidsetBname(String bname){this.bname = bname;}publicString getBauthor(){returnbauthor;}publicvoidsetBauthor(String bauthor){this.bauthor = bauthor;}publicDate getBtime(){returnbtime;}publicvoidsetBtime(Date btime){this.btime = btime;}publicintgetBtype(){returnbtype;}publicvoidsetBtype(intbtype){this.btype = btype;}}

BookManageMapper.java

packagecom.dao;importcom.entity.BookManage;importjava.util.List;publicinterfaceBookManageMapper{//查询全部List<BookManage> findBookAll();//添加intaddBook(BookManage bookManage);//删除intdelBook(intbid);}

BookManageMapper.xml

<?xml version="1.0"encoding="UTF-8"?><!DOCTYPE mapperPUBLIC "-////DTD Mapper 3.0//EN""/dtd/mybatis-3-mapper.dtd"><mappernamespace="com.dao.BookManageMapper"><selectid="findBookAll"resultType="BookManage">select * from BookManage;</select><insertid="addBook"parameterType="BookManage">insert into bookmanage (bname,bauthor,btime,btype)value(#{bname},#{bauthor},#{btime},#{btype});</insert><deleteid="delBook"parameterType="int">delete from BookManage where bid = #{bid};</delete></mapper>

IBookManageService.java

packagecom.service;importcom.entity.BookManage;importjava.util.List;publicinterfaceIBookManageService{//查询全部List<BookManage> findBookAll();//添加intaddBook(BookManage bookManage);//删除intdelBook(intbid);}

BookManageServiceImpl.java

packagecom.service.impl;importcom.dao.BookManageMapper;importcom.entity.BookManage;importcom.service.IBookManageService;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.stereotype.Service;importjava.util.List;@Service("bookManageService")publicclassBookManageServiceImplimplementsIBookManageService{@AutowiredprivateBookManageMapper bookManageMapper;@OverridepublicList<BookManage> findBookAll(){returnbookManageMapper.findBookAll();}@OverridepublicintaddBook(BookManage bookManage){returnbookManageMapper.addBook(bookManage);}@OverridepublicintdelBook(intbid){returnbookManageMapper.delBook(bid);}publicBookManageMapper getBookManageMapper(){returnbookManageMapper;}publicvoidsetBookManageMapper(BookManageMapper bookManageMapper){this.bookManageMapper = bookManageMapper;}}

IndexController.java

packagecom.web;importcom.entity.BookManage;importcom.service.IBookManageService;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.stereotype.Controller;importorg.springframework.ui.Model;importorg.springframework.web.bind.annotation.RequestMapping;importjava.util.List;@Controller@RequestMapping("/")publicclassIndexController{//创建Service的对象@AutowiredprivateIBookManageService bookManageService;//默认进入首页@RequestMapping("/")publicString index(Model model){List<BookManage> bookManageList =bookManageService.findBookAll();model.addAttribute("bookManageList",bookManageList);return"index";}//删除@RequestMapping("delBook")publicString delBook(Model model,intbid){bookManageService.delBook(bid);index(model);return"index";}//添加@RequestMapping("addBook")publicString addBook(BookManage bookManage,Model model){bookManageService.addBook(bookManage);index(model);return"index";}publicIBookManageService getBookManageService(){returnbookManageService;}publicvoidsetBookManageService(IBookManageService bookManageService){this.bookManageService = bookManageService;}}

05

引入jQuery环境

将jquery的环境拷贝到项目中的webapp下：

06

首页

修改index.jsp,使其实现进入页面即查询数据库中所有数据功能，代码如下：

<%--CreatedbyIntelliJIDEA.User:24519Date:/1/20Time:10:38TochangethistemplateuseFile| Settings| FileTemplates.--%><%@pageisELIgnored="false"%><%@pagecontentType="text/html;charset=UTF-8"language="java"%><%@taglibprefix="c"uri="/jsp/jstl/core"%><%@taglibprefix="f"uri="/jsp/jstl/fmt"%><html><head><title>首页</title></head><body><h1>图书信息</h1><tableborder="1"><tr><td>图书名称</td><td>图书作者</td><td>购买时间</td><td>图书分类</td><td>操作</td></tr><c:forEachitems="${bookManageList}"var="book"><tr><td>${book.bname}</td><td>${book.bauthor}</td><td><f:formatDatevalue="${book.btime}"pattern="yyyy-MM-dd"></f:formatDate></td><td><c:iftest="${book.btype==1}">计算机/软件</c:if><c:iftest="${book.btype==2}">小说/文摘</c:if><c:iftest="${book.btype==3}">杂项</c:if></td><td><ahref="delBook?bid=${book.bid}">删除</a></td></tr></c:forEach></table><ahref="addBook.jsp"style="color:red">新增图书信息</a><scriptsrc="js/jquery-1.12.4.js"type="text/javascript"></script><scripttype="text/javascript">$(function(){$("tr:even").css("background","green");$("tr:first").css("background","blue");});</script></body></html>

07

添加图书的页面

创建添加数据的页面addBook.jsp,代码如下：

注意，addBook.jsp和index.jsp都需要放在webapp目录下。

08

配置tomcat

测试发现，正常运行。

最后附数据库脚本代码：

/*SQLyog Professional v12.08 (32 bit)MySQL - 5.5.27 : Database - schooldb**********************************************************************//*!40101 SET NAMES utf8 */;/*!40101 SET SQL_MODE=''*/;/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;CREATEDATABASE/*!32312 IF NOT EXISTS*/`schooldb`/*!40100 DEFAULT CHARACTER SET utf8 */;USE`schooldb`;/*Table structure for table `bookmanage` */DROPTABLEIFEXISTS`bookmanage`;CREATETABLE`bookmanage`(`bid`int(11) NOTNULLAUTO_INCREMENT,`bname`varchar(40) NOTNULL,`bauthor`varchar(40) NOTNULL,`btime`datetime NOTNULL,`btype`int(11) NOTNULL,PRIMARY KEY(`bid`)) ENGINE=InnoDBAUTO_INCREMENT=5DEFAULTCHARSET=utf8;/*Data for the table `bookmanage` */insertinto`bookmanage`(`bid`,`bname`,`bauthor`,`btime`,`btype`) values(1,'三国演义','罗贯中','-09-08 00:00:00',2),(2,'水浒传','施耐庵','-09-08 00:00:00',2),(3,'狂人日记','魯迅','-09-08 00:00:00',3),(4,'改善java的151个建议','秦少波','-09-08 00:00:00',1);/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;
