ssm基础搭建步骤
2019-03-01 10:13:35来源:博客园 阅读 ()
今天搭建新的项目环境,从网上找了些ssm的搭建步骤,终于找到了一位csdn的大佬,可以说写的特别详细,按照上面步骤搭建即可,为了方便日后参考,转载到本人博客,原文链接:https://blog.csdn.net/khxu666/article/details/79851070;
这篇文章主要以idea做参考,没有的自己破解,其余的工具可以根据下面步骤下载安装和使用
开发工具
- IntelliJ IDEA Ultimate 2017.2.2
- Apache-tomcat-9.0.5
- JDK 1.8.0_121
- MySQL 5.7
- Maven 3.3.9
工程结构
最终完成后的工程结构:
下面开始详细的讲解项目的开发过程。
IDEA+Maven搭建项目骨架
1. 新建Maven项目:
点击File -> New -> Project -> Maven -> 勾选 Create from archetype -> 选择 maven-archetype-webapp (注意:此处不要错选成上面的cocoom-22-archetype-webapp)
在弹出的new project 选项卡中填写GroupId和Artifactid,其中GroupID是项目组织唯一的标识符,实际对应JAVA的包的结构,是main目录里java的目录结构,ArtifactID是项目的唯一的标识符,实际对应项目的名称,就是项目根目录的名称。对于入门练习,这两项可以随意填写。
之后点击next 选择Maven版本(其中IDEA 专业版自带Maven,也可以选择自己下载的maven)。之后填写项目名称和项目地址,完成后点击Finish,完成项目骨架的创建。
2. 在新建的项目中添加所需要的文件/文件夹
创建之后的项目如图所示,我们需要在这之上新建一些目录。
在项目的根目录下新建target文件夹,系统自动将其设置为“Excluded”
在src/main目录下新建Directory:“java”,并将其设置为“Source Root”(即:此项目默认的代码文件源目录)
在刚才新建的java文件下新建“com”包,再在com包下新建四个包,分别命名为:pojo,service,dao,controller。(如果出现下图中所示的包名重叠的情况,可以点击图中所示的图标,将“Hide empty middle package取消掉”)
上面新建的四个包:pojo,service,dao,controller,其所存放的分别是:
pojo: 存放自定义的java类。如:paper类,user类,book类等,每个类的属性设为private,并提供public属性的getter/setter方法让外界访问
service:定义接口,包含系统所提供的功能。(之后还会在service包下再新建impl包)。
dao:定义接口,包含与数据库进行交互的功能。
controller:控制器,负责接收页面请求,转发和处理。
在resource包下新建Directory:“mapper”(用于存放xxxMapper.xml文件)和“spring”(用于存放spring-xxx.xml配置文件),新建文件:“jdbc.properties”(mysql数据库配置文件),”log4j.properties”(日志输出配置文件),”mybatis-config.xml”(mybatis框架配置文件)。
在web-inf目录下新建“jsp”包,存放xxx.jsp显示界面。
补充之后的项目目录如下图所示,至此项目骨架搭建完毕,开始写代码实现增删改查功能。
3. 自定义Paper类
在这之前要对项目的pom.xml文件进行配置,在此文件中配置项目所需要的jar包。
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com</groupId> <artifactId>first</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>first Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <spring.version>5.0.3.RELEASE</spring.version> <mybatis.version>3.4.4</mybatis.version> </properties> <dependencies> <!-- 单元测试 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- 第一部分:Spring 配置--> <!-- Spring core --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <!-- Spring DAO --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <!-- Spring mvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- 第二部分:Servlet web --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>taglibs</groupId> <artifactId>standard</artifactId> <version>1.1.2</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.4</version> </dependency> <!-- 第三部分:数据库和mybatis --> <!-- 数据库 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.38</version> </dependency> <!-- 数据库连接池 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> <!-- MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis-spring整合包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.1</version> </dependency> <!-- 第四部分:日志 --> <!-- 实现slf4j接口并整合 --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.1.1</version> </dependency> </dependencies> <build> <finalName>first</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
本项目所用的数据库为MySQL 5.7 建表语句如下:
SET FOREIGN_KEY_CHECKS=0; -- ---------------------------- -- Table structure for `paper` -- ---------------------------- DROP TABLE IF EXISTS `paper`; CREATE TABLE `paper` ( `paper_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT 'paperID', `name` varchar(100) NOT NULL COMMENT 'paper名称', `number` int(11) NOT NULL COMMENT 'paper数量', `detail` varchar(200) NOT NULL COMMENT 'paper描述', PRIMARY KEY (`paper_id`) ) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8 COMMENT='paper表'; -- ---------------------------- -- Records of paper -- ---------------------------- INSERT INTO `paper` VALUES ('1', '机器学习', '2', 'mlmlmlml'); INSERT INTO `paper` VALUES ('2', '深度学习', '3', 'dldldl'); INSERT INTO `paper` VALUES ('3', '大数据', '4', 'bdbdbd');
下面开始写java代码:
- 在pojo包中新建Paper.java
package com.pojo; public class Paper { private long paperId; private String paperName; private int paperNum; private String paperDetail; public long getPaperId() { return paperId; } public void setPaperId(long paperId) { this.paperId = paperId; } public String getPaperName() { return paperName; } public void setPaperName(String paperName) { this.paperName = paperName; } public int getPaperNum() { return paperNum; } public void setPaperNum(int paperNum) { this.paperNum = paperNum; } public String getPaperDetail() { return paperDetail; } public void setPaperDetail(String paperDetail) { this.paperDetail = paperDetail; } }
其中getter/setter方法可以在定义完私有属性之后使用IDEA提供的快捷键:ALT+Insert 来实现快速添加
- 在service包中新建接口 PaperService:
package com.service; import com.pojo.Paper; import java.util.List; public interface PaperService { int addPaper(Paper paper); int deletePaperById(long id); int updatePaper(Paper paper); Paper queryById(long id); List<Paper> queryAllPaper(); }
- 在service包下新建impl包,并在此包中新建PaperServiceImpl.java
package com.service.impl; import com.pojo.Paper; import com.dao.PaperDao; import com.service.PaperService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; @Service public class PaperServiceImpl implements PaperService { @Autowired private PaperDao paperDao; @Override public int addPaper(Paper paper) { return paperDao.addPaper(paper); } @Override public int deletePaperById(long id) { return paperDao.deletePaperById(id); } @Override public int updatePaper(Paper paper) { return paperDao.updatePaper(paper); } @Override public Paper queryById(long id) { return paperDao.queryById(id); } @Override public List<Paper> queryAllPaper() { return paperDao.queryAllPaper(); } }
- 在dao包中新建接口 PaperDao.java
package com.dao; import com.pojo.Paper; import java.util.List; public interface PaperDao { int addPaper(Paper paper); int deletePaperById(long id); int updatePaper(Paper paper); Paper queryById(long id); List<Paper> queryAllPaper(); }
- 在controller包中新建 PaperController.java
package com.controller; import com.pojo.Paper; import com.service.PaperService; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; @Controller @RequestMapping("/paper") public class PaperController { @Autowired private PaperService paperService; @RequestMapping("/allPaper") public String list(Model model) { List<Paper> list = paperService.queryAllPaper(); model.addAttribute("list", list); return "allPaper"; } @RequestMapping("toAddPaper") public String toAddPaper() { return "addPaper"; } @RequestMapping("/addPaper") public String addPaper(Paper paper) { paperService.addPaper(paper); return "redirect:/paper/allPaper"; } @RequestMapping("/del/{paperId}") public String deletePaper(@PathVariable("paperId") Long id) { paperService.deletePaperById(id); return "redirect:/paper/allPaper"; } @RequestMapping("toUpdatePaper") public String toUpdatePaper(Model model, Long id) { model.addAttribute("paper", paperService.queryById(id)); return "updatePaper"; } @RequestMapping("/updatePaper") public String updatePaper(Model model, Paper paper) { paperService.updatePaper(paper); paper = paperService.queryById(paper.getPaperId()); model.addAttribute("paper", paper); return "redirect:/paper/allPaper"; } }
- 在resource/mapper包下新建 PaperMapper.xml(mybatis框架mapper代理开发配置文件)
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.dao.PaperDao"> <resultMap type="Paper" id="paperResultMap" > <id property="paperId" column="paper_id"/> <result property="paperName" column="name"/> <result property="paperNum" column="number"/> <result property="paperDetail" column="detail"/> </resultMap> <insert id="addPaper" parameterType="Paper"> INSERT INTO paper(paper_id,name,number,detail) VALUE (#{paperId},#{paperName}, #{paperNum}, #{paperDetail}) </insert> <delete id="deletePaperById" parameterType="long"> DELETE FROM paper WHERE paper_id=#{paperID} </delete> <update id="updatePaper" parameterType="Paper"> UPDATE paper SET NAME = #{paperName},NUMBER = #{paperNum},detail = #{paperDetail} WHERE paper_id = #{paperId} </update> <select id="queryById" resultType="Paper" parameterType="long"> SELECT paper_id,name,number,detail FROM paper WHERE paper_id=#{paperId} </select> <select id="queryAllPaper" resultMap="paperResultMap"> SELECT paper_id,name,number,detail FROM paper </select> </mapper>
- 在resource/spring包下分别新建配置文件:spring-dao.xml , spring-mvc.xml , spring-service.xml
spring-dao.xml:(spring-mybatis整合配置文件)

4. 利用tomcat进行项目部署
- 下载 安装 tomcat:tomcat 9 下载地址
- IDEA配置tomcat:
点击上方的 Run 选项,选择Edit Configuration
选择default -> tomcat -> local 选择下载安装到本地的tomcat服务器的地址
切换到Deployment选项页 点击 + 号选择 Arctifact ,
添加 项目名:war exploded 打包
最后在Application context 中选择 空白 那一项,点击 Apply 应用。
- 最后切换到index.jsp界面,右键运行项目
5. 运行界面
论文列表界面:
新增论文界面:
论文修改界面:
至此,利用IDEA+Maven+SSM框架实现的简单的增、删、改、查功能已经构建完毕!
