大家好,我是雄雄,欢迎关注微信公众号【雄雄的小课堂】。
前言
最近这几天都在看关于springboot的内容,每天新会获得点新收获,并且都总结发在公众号中;最后经过不懈努力,不断查找相关网页,解决各种各样的问题,终于搭建出来了个新版的“S(springboot)S(springmvc)M(mybatis)框架”,下面是搭建步骤。
01
在idea中创建springboot项目
在idea编辑器中,点击File->New->Project->Spring Initializr->选择jdk版本为1.8,然后点击Next
然后按照下图修改各个输入框的值,然后点击Next
选择web,勾上spring web
接下来选择sql,勾上对应的jdbc,mybaits和mysql driver,然后点击Next
然后点击Finish,新建完的项目结构如下:
到现在为止,一个崭新的springboot+Maven项目就搭建好了,接下来我们来配置一下pom.xml文件。
02
配置pom.xml文件
由于我们前端需要使用jsp来展示数据,所以pom.xml文件里面需要配置一个编译解析jsp页面的依赖,代码如下:
<!--用于解析jsp页面--><dependency><groupId>org.apache.tomcat.embed</groupId><artifactId>tomcat-embed-jasper</artifactId></dependency><dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat-jsp-api</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId><scope>provided</scope></dependency>
在首页我这边需要用到jstl来展示数据,所以还需要导入jstl的相关依赖,如下所示:
<!--jstl相关依赖--><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId></dependency>
03
编写application.properties文件
虽然springboot对配置文件简化了很多,但是必要的配置还是要有的, 那么这些配置就都放在了application.properties文件中,也有的项目中是application.yml文件,在这里我们以application.properties文件为例:
首先需要配置一下服务器的端口号,默认为8080,也可以改,代码如下:
#服务器端口号
server.port=8080
配置数据池:
#配置数据池
spring.datasource.url=jdbc:mysql://localhost:3306/schooldb
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=root
配置mybatis的别名:
#起别名
mybatis.type-aliases-package=com.xiongxiong.entity
配置日志信息:
#配置日志
logging.level.com.xiongxiong.dao = debug
logging.file.path=log/
logging.file.name=book.log
配置springmvc的内容
#配置springmvc的内容
#页面默认前缀配置
spring.mvc.view.prefix=/
#页面默认后缀配置
spring.mvc.view.suffix=.jsp
这是些基础的配置,如果还有其他扩展,可以自行添加配置信息。
04
搭建底层的三层架构(数据库脚本和结构在文末)
BookManage
在com.xiongxiong下面新建包entity,存放实体类BookManage,按照数据库表中的字段,对应写实体类的属性,最后getter和setter,代码如下:
package com.xiongxiong.entity;import org.springframework.format.annotation.DateTimeFormat;import java.util.Date;public class BookManage {private int bid;private String bname;private String bauthor;@DateTimeFormat(pattern = "yyyy-MM-dd")private Date btime;private int btype;public int getBid() {return bid;}public void setBid(int bid) {this.bid = bid;}public String getBname() {return bname;}public void setBname(String bname) {this.bname = bname;}public String getBauthor() {return bauthor;}public void setBauthor(String bauthor) {this.bauthor = bauthor;}public Date getBtime() {return btime;}public void setBtime(Date btime) {this.btime = btime;}public int getBtype() {return btype;}public void setBtype(int btype) {this.btype = btype;}
}
BookManageMapper
在com.xiongxiong中新建包dao,在该包中创建接口BookManageMapper,分别编写增删改以及查询全部和根据编号查询的接口。
package com.xiongxiong.dao;import com.xiongxiong.entity.BookManage;
import org.apache.ibatis.annotations.*;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;
import org.springframework.web.bind.annotation.ResponseBody;import java.util.List;@Mapper //证明是mybatis的mapper文件
@Repository //证明这是dao层
public interface BookManageMapper {@Select("select * from BookManage;")//查询全部List<BookManage> findBookAll();@Insert("insert into bookmanage (bname,bauthor,btime,btype) value(#{bname},#{bauthor},#{btime},#{btype});")//添加int addBook(BookManage bookManage);@Delete("delete from BookManage where bid = #{bid};")//删除int delBook(int bid);@Update("update bookmanage set bname=#{bname},bauthor=#{bauthor},btime=#{btime},btype=#{btype} where bid = #{bid}")//修改int updateBook(BookManage bookManage);@Select("select * from bookmanage where bid = #{bid}")//根据编号查询编号BookManage findBookById(int bid);
}
需要注意的是,由于我们统一都使用注解的方式,所以不用在编写SQL映射文件(mapper),所有的sql语句通过注解方式实现,详情请看代码,各个功能都有相应的注释。
IBookManageService和BookManageServiceImpl
同样,在com.xiongxiong包下面创建service包存放业务的接口,在service包下面新建impl包,存放的是业务接口的实现类,代码如下:
IBookManageService
package com.xiongxiong.service;import com.xiongxiong.entity.BookManage;
import org.apache.ibatis.annotations.Delete;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.Update;import java.util.List;public interface IBookManageService {//查询全部List<BookManage> findBookAll();//添加int addBook(BookManage bookManage);//删除int delBook(int bid);//修改int updateBook(BookManage bookManage);//根据编号查询编号BookManage findBookById(int bid);}
BookManageServiceImpl
package com.xiongxiong.service.impl;import com.xiongxiong.dao.BookManageMapper;
import com.xiongxiong.entity.BookManage;
import com.xiongxiong.service.IBookManageService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.transaction.annotation.Transactional;import java.util.List;@EnableTransactionManagement //开启事务管理器
@Transactional //配置事务
@Service //证明这是一个service层
public class BookManageServiceImpl implements IBookManageService {//Dao层的接口@AutowiredBookManageMapper bookManageMapper;@Overridepublic List<BookManage> findBookAll() {return bookManageMapper.findBookAll();}@Overridepublic int addBook(BookManage bookManage) {return bookManageMapper.addBook(bookManage);}@Overridepublic int delBook(int bid) {return bookManageMapper.delBook(bid);}@Overridepublic int updateBook(BookManage bookManage) {return bookManageMapper.updateBook(bookManage);}@Overridepublic BookManage findBookById(int bid) {return bookManageMapper.findBookById(bid);}}
需要注意的是,在实现类中,需要添加开启事务@EnableTransactionManagement和配置事务@Transactional的注解。
在com.xiongxiong下面创建包web,该包中放控制器,在控制器中实现增删改查的功能以及页面之间的跳转,代码如下:
package com.xiongxiong.web;import com.xiongxiong.entity.BookManage;
import com.xiongxiong.service.IBookManageService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;import java.util.List;@Controller
public class IndexController {//创建Service的对象@Autowiredprivate IBookManageService bookManageService;//默认进入首页@RequestMapping("default")public String index(Model model) {List<BookManage> bookManageList =bookManageService.findBookAll();model.addAttribute("bookManageList",bookManageList);return "index";}//删除@RequestMapping("delBook")public String delBook(Model model, int bid) {bookManageService.delBook(bid);index(model);return "index";}//添加@RequestMapping("addBook")public String addBook(BookManage bookManage, Model model) {bookManageService.addBook(bookManage);index(model);return "index";}//跳转到添加的页面@RequestMapping("add")public String add() {return "addBook";}}
05
创建jsp页面
在main下面新建文件夹webapp,在该文件夹中新建jsp页面就可以,其中我还用到了jquery(下面有下载链接)的环境,放在js目录下面,目录结构如下所示:
jquery-1.12.4.js:点此下载
bootstrap.js:点此下载
创建index.jsp,用来展示查询展示所有数据,查询的功能在控制器IndexController中实现的,下面是代码:

<head><title>首页</title>
</head>
<body>

<table border="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:forEach items="${bookManageList}" var="book"><tr><td>${book.bname}</td><td>${book.bauthor}</td><td><f:formatDate value="${book.btime}" pattern="yyyy-MM-dd"></f:formatDate></td><td><c:if test="${book.btype==1}">计算机/软件</c:if><c:if test="${book.btype==2}">小说/文摘</c:if><c:if test="${book.btype==3}">杂项</c:if></td><td><a href="delBook?bid=${book.bid}">删除</a></td></tr></c:forEach></table>
<a href="addBook.jsp" style="color:red">新增图书信息</a>
<script src="js/jquery-1.12.4.js" type="text/javascript"></script>
<script type="text/javascript">$(function () {$("tr:even").css("background", "green");$("tr:first").css("background", "blue");});
</script>
</body>
</html>
创建添加信息的jsp页面addBook.jsp,主要用来添加信息,添加的功能在控制器IndexController中实现,还实现了必要的表单验证,下面是代码:
<%--Created by IntelliJ IDEA.User: 24519Date: 2021/1/20Time: 11:35To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>Title</title>
</head>
<body>
<h1>新增图书信息</h1>
<form action="addBook" method="post">图书名称:<input type="text" name="bname"/><br/>图书作者:<input type="text" name="bauthor"/><br/>购买日期:<input type="text" name="btime"/><br/>图书类别:<select name="btype"><option value="0">选择所属分类</option><option value="1">计算机/软件</option><option value="2">小说/文摘</option><option value="3">杂项</option></select><br/><input type="submit" value="增加图书"/>
</form>
<script src="js/jquery-1.12.4.js" type="text/javascript"></script>
<script type="text/javascript">$(function () {$("input[type='submit']").click(function () {var bname = $("input[name='bname']").val();var bauthor = $("input[name='bauthor']").val();var btime = $("input[name='btime']").val();var btype = $("input[name='btype']").val();if (bname == "") {alert("图书名称不能为空");return false;}if (bauthor == "") {alert("图书作者不能为空");return false;}var dateinfo = /^[0-9]{4}-[0-1]{1}[0-9]{1}-[0-3]{1}[0-9]{1}/;if (!dateinfo.test(btime)) {alert("日期格式不正确");return false;}if (btype == 0) {alert("图书分类需要选择");return false;}});});
</script>
</body>
</html>
然后启动,运行,运行结果如下:
