环境要求
环境：
- IDEA
- MySQL 5.7.19
- Tomcat 9
- Maven 3.6
要求：
- 需要熟练掌握MySQL数据库，Spring，JavaWeb及MyBatis知识，简单的前端知识；
一、底层
数据库环境
创建一个存放书籍数据的数据库表
`ssmbuild`
USE `ssmbuild`;
CREATE TABLE `books` (
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
`bookName` VARCHAR(100) NOT NULL COMMENT '书名',
`bookCounts` INT(11) NOT NULL COMMENT '数量',
`detail` VARCHAR(200) NOT NULL COMMENT '描述',
KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8
INSERT INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');
基本环境搭建
1、新建一Maven项目！ssmbuild ， 添加web的支持
2、导入相关的pom依赖！

3、Maven资源过滤设置
<build>
<resources>
<resource>
<directory>src/main/javadirectory>
<includes>
<include>**/*.propertiesinclude>
<include>**/*.xmlinclude>
includes>
<filtering>falsefiltering>
resource>
<resource>
<directory>src/main/resourcesdirectory>
<includes>
<include>**/*.propertiesinclude>
<include>**/*.xmlinclude>
includes>
<filtering>falsefiltering>
resource>
resources>
build>
4、建立基本结构和配置框架！
- com.kk.pojo
- com.kk.dao
- com.kk.service
- com.kk.controller
- mybatis-config.xml
mybatis-config.xml
DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
configuration>
applicationContext.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
beans>
Mybatis层编写
1、数据库配置文件 database.properties
driver=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/mybatis?useSSL=true&useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8&allowPublicKeyRetrieval=true
username=root
password=123456
2、IDEA关联数据库文件 spring-dao.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd">
<context:property-placeholder location="classpath:database.properties"/>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="maxPoolSize" value="30"/>
<property name="minPoolSize" value="10"/>
<property name="autoCommitOnClose" value="false"/>
<property name="checkoutTimeout" value="10000"/>
<property name="acquireRetryAttempts" value="2"/>
bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:mybatis-config.xml"/>
bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<property name="basePackage" value="com.kk.dao"/>
bean>
beans>
3、编写MyBatis的核心配置文件 mybatis-config.xml
DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>
<setting name="logImpl" value="STDOUT_LOGGING"/>
settings>
<typeAliases>
<package name="com.kk.pojo"/>
typeAliases>
<mappers>
<mapper resource="com/kk/dao/BookMapper.xml"/>
mappers>
configuration>
4、编写数据库对应的实体类 com.kk.pojo.Books
使用lombok插件！
<dependency>
<groupId>org.projectlombokgroupId>
<artifactId>lombokartifactId>
<version>1.18.12version>
dependency>
package com.kk.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {
private int bookID;
private String bookName;
private int bookCounts;
private String detail;
}
5、编写Dao层的 Mapper接口！
package com.kk.dao;
import com.kk.pojo.Books;
import org.apache.ibatis.annotations.Param;
import java.util.List;
public interface BookMapper {
//增加一个Book
int addBook(Books book);
//根据id删除一个Book
int deleteBookById(@Param("bookID") int id);
//更新Book
int updateBook(Books books);
//根据id查询,返回一个Book
Books queryBookById(@Param("bookID") int id);
//查询全部Book,返回list集合
List<Books> queryAllBook();
//搜索书籍模块
Books queryBookByName(@Param("bookName") String bookName);
}
6、编写接口对应的 Mapper.xml 文件。需要导入MyBatis的包；
DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.kk.dao.BookMapper">
<insert id="addBook" parameterType="Books">
insert into ssmbuild.books(bookName,bookCounts,detail)
values (#{bookName}, #{bookCounts}, #{detail})
insert>
<delete id="deleteBookById" parameterType="int">
delete from ssmbuild.books where bookID=#{bookID}
delete>
<update id="updateBook" parameterType="Books">
update ssmbuild.books
set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
where bookID = #{bookID}
update>
<select id="queryBookById" resultType="Books">
select * from ssmbuild.books
where bookID = #{bookID}
select>
<select id="queryAllBook" resultType="Books">
select * from ssmbuild.books
select>
<select id="queryBookByName" resultType="Books">
select * from ssmbuild.books where bookName=#{bookName}
select>
mapper>
7、编写Service层的接口和实现类
接口：
package com.kk.service;
import com.kk.pojo.Books;
import org.apache.ibatis.annotations.Param;
import java.util.List;
//BookService:底下需要去实现,调用dao层
public interface BookService {
//增加一个Book
int addBook(Books book);
//根据id删除一个Book
int deleteBookById(int id);
//更新Book
int updateBook(Books books);
//根据id查询,返回一个Book
Books queryBookById(int id);
//查询全部Book,返回list集合
List<Books> queryAllBook();
//搜索书籍模块
Books queryBookByName(String bookName);
}
实现类：BookServiceImp
package com.kk.service;
import com.kk.dao.BookMapper;
import com.kk.pojo.Books;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class BookServiceImp implements BookService{
//调用dao层的操作，设置一个set接口，方便Spring管理
@Autowired
private BookMapper bookMapper;
public void setBookMapper(BookMapper bookMapper) {
this.bookMapper = bookMapper;
}
@Override
public int addBook(Books book) {
return bookMapper.addBook(book);
}
@Override
public int deleteBookById(int id) {
return bookMapper.deleteBookById(id);
}
@Override
public int updateBook(Books books) {
System.out.println("BookServiceImp:updateBook=>"+books);
return bookMapper.updateBook(books);
}
@Override
public Books queryBookById(int id) {
return bookMapper.queryBookById(id);
}
@Override
public List<Books> queryAllBook() {
return bookMapper.queryAllBook();
}
@Override
public Books queryBookByName(String bookName) {
return bookMapper.queryBookByName(bookName);
}
}
OK，到此，底层需求操作编写完毕！
二、Spring层
1、配置Spring整合MyBatis，这里数据源使用c3p0连接池；
2、编写Spring整合Mybatis的相关的配置文件；spring-dao.xml
3、Spring整合service层
spring-dao.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd">
<context:property-placeholder location="classpath:database.properties"/>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="maxPoolSize" value="30"/>
<property name="minPoolSize" value="10"/>
<property name="autoCommitOnClose" value="false"/>
<property name="checkoutTimeout" value="10000"/>
<property name="acquireRetryAttempts" value="2"/>
bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:mybatis-config.xml"/>
bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<property name="basePackage" value="com.kk.dao"/>
bean>
beans>
4、Spring整合service层
spring-service.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"

http://www.springframework.org/schema/beans/spring-beans.xsd">
<import resource="classpath:spring-dao.xml"/>
<import resource="classpath:spring-service.xml"/>
beans>
三、SpringMVC层
1、web.xml
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
bean>
beans>
3、Spring配置整合文件，applicationContext.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<import resource="classpath:spring-dao.xml"/>
<import resource="classpath:spring-service.xml"/>
<import resource="classpath:spring-mvc.xml"/>
beans>
配置文件，暂时结束！Controller 和 视图层编写
1、BookController 类编写 ， 方法一：查询全部书籍
@Controller
@RequestMapping("/book")
public class BookController {
//controller层调service层
@Autowired
@Qualifier("BookServiceImp")
private BookService bookService;
//查询全部的书籍 并且返回到一个书籍展示页面
@RequestMapping("/allBook")
public String list(Model model){
List<Books> list = bookService.queryAllBook();
model.addAttribute("list",list);
return "allBook";
}
}
2、编写首页 index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
$Title$
进入书籍页面
3、书籍列表页面 allbook.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
查询书籍展示页面
<%--BookStrap美化界面--%>
4、BookController 类编写 ， 方法二：添加书籍
// 跳转到增加书籍页面
@RequestMapping("/toAddBook")
public String toAddPage(){
return "addBook";
}
// 添加书籍的请求
@RequestMapping("/addBook")
public String addBook(Books books){
System.out.println("addBook=>"+books);
bookService.addBook(books);
return "redirect:/book/allBook";// 重定向到我们的 @RequestMapping("/allBook")请求；
}
5、添加书籍页面：addBook.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
Title
<%--BookStrap美化界面--%>
新增书籍
6、BookController 类编写 ， 方法三：修改书籍
// 跳转到修改书籍页面
@RequestMapping("/toUpdatePage")
public String toUpdatePage(Model model,int id){
Books books = bookService.queryBookById(id);
System.out.println(books);
model.addAttribute("QBooks",books);
return "updateBook";
}
// 修改书籍请求
@RequestMapping("/updateBook")
public String updateBook(Model model,Books books){
System.out.println("updateBook=>"+books);
int i = bookService.updateBook(books);//真正修改到业务层进行修改
if (i>0){
System.out.println("添加books成功"+books);
}
return "redirect:/book/allBook";
}
7、修改书籍页面 updateBook.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
修改书籍信息
<%--BookStrap美化界面--%>
修改书籍信息
8、BookController 类编写 ， 方法四：删除书籍
//删除书籍
@RequestMapping("/deleteBook/{bookId}")
public String deleteBook(@PathVariable("bookId") int id){
bookService.deleteBookById(id);
return "redirect:/book/allBook";
}
8、BookController 类编写 ， 方法五：查询书籍
//查询书籍
@RequestMapping("/queryBook")
public String queryBook(String queryBookName,Model model){
//从前端接收名字
Books books = bookService.queryBookByName(queryBookName);
System.err.println("queryBook=>"+books);
List<Books> list=new ArrayList<Books>();
list.add(books); //查询出来只显示这一本
if (books==null){
list=bookService.queryAllBook();
model.addAttribute("error","未查到");
}
model.addAttribute("list",list);
return "allBook";
}
9、 方法四：删除书籍、方法五：查询书籍相关jsp,合并在allBook.jsp中
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
查询书籍展示页面
<%--BookStrap美化界面--%>
书籍详情
操作
<%-- 书籍从数据库中查询出来，从这个list中遍历出来，foreach--%>
${book.bookID}
${book.bookName}
${book.bookCounts}
${book.detail}
