完整SSM框架图书管理系统开发流程

环境：
IDEA
MySQL 5.5.62
Tomcat 8.5.61
Maven 3.6
1.数据库环境
创建一个存放书籍数据的数据库表

CREATE DATABASE `ssmbuild`;

USE `ssmbuild`;

DROP TABLE IF EXISTS `books`;

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');

2.基本环境搭建

• 新建一Maven项目！ssmbuild ， 添加web的支持
• 导入相关的pom依赖

3.maven资源解析

<build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>
    </build>

4.基本结构和配置框架

5.配置mybatis-config.xml(只需配置设置和别名即可，其他使用spring的数据源替换Mybatis的配置)

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>  <!--核心配置文件-->  <!--在xml中所有标签都要规定其顺序-->
    <!--1引入web配置文件-->

    <!--2设置-->
    <!--开启驼峰命名映射是否开启驼峰命名自动映射，即从经典数据库列名 A_COLUMN 映射到经典 Java 属性名 aColumn。 -->
   <settings>
        <setting name="mapUnderscoreToCamelCase" value="true"/>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
      <!--显示开启全局缓存-->
        <setting name="cacheEnabled" value="true"/>
    </settings>
   
    <typeAliases>
        <typeAlias type="com.ji.pojo.Books"/>
    </typeAliases>
  <!--每一个Mapper.xml都需要在mybatis核心配置文件中注册-->
    <!--使用注解时不需要绑定配置文件，需要绑定接口-->
    <mappers>
        <package name="com.ji.dao"/>
    </mappers>
</configuration>

5.编写pojo层
实体类

package com.ji.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;
}

6.编写dao层（操作数据库）
Mapper接口

package com.ji.dao;

import com.ji.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BooksMapper {
    //增加
    int addBook(Books books);
    //删除
    int deleteBooks(@Param ("bookID") int id);
    //更改
    int updateBooks(Books books);
    //查询一本书
    Books queryBooks(@Param ("bookID") int id);

    List<Books> queryAllBooks();

    List<Books> queryBookByName(String bookName);
}

mapper.xml映射文件

<?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.ji.dao.BooksMapper">
    <insert id="addBook" parameterType="Books">
        insert into `books`(`bookName`,`bookCounts`,`detail`)
        values (#{bookName},#{bookCounts},#{detail})
    </insert>
    <delete id="deleteBooks" parameterType="int">
        delete from `books`
        <where>
            `bookID`=#{bookID}
        </where>
    </delete>
    <update id="updateBooks" parameterType="Books">
        update `books`
        <set>
            `bookName`=#{bookName},`bookCounts`=#{bookCounts},`detail`=#{detail}
        </set>
        <where>
            `bookID`=#{bookID}
        </where>
    </update>
    <select id="queryBooks" parameterType="int" resultType="Books">
        select * from `books`
        <where>
            `bookID`=#{bookID}
        </where>
    </select>
    <select id="queryBookByName" parameterType="String" resultType="Books">
        select * from `books`
        <where>
            `bookName`=#{bookName}
        </where>
    </select>

    <select id="queryAllBooks" resultType="Books">
        select * from `books`
    </select>
</mapper>

使用spring-dao.xml代替mybatis-config.xml配置数据源

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:c="http://www.springframework.org/schema/c"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        https://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--关联数据库配置文件-->
    <context:property-placeholder location="classpath:db.properties"/>
    <!--连接池-->
    <bean id="datasource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&amp;useUnicode=true&amp;characterEncoding=UTF-8"/>
        <property name="user" value="root"/>
        <property name="password" value="root"/>
    </bean>
<!--sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="datasource"/>
        <property name="configLocation" value="classpath:mybatis-config.xml"/>

    </bean>
    <!--配置dao接口扫描包，动态实现了dao接口可以注入到spring容器中  无需继承实现类和私有化构造sqlSessionTemplate-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--注入sqlSessionFactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!--扫描要扫描的包-->
        <property name="basePackage" value="com.ji.dao"/>
    </bean>
    <!--sqlSessionTemplate   继承实现类-->
</beans>

7.编写service层
spring-service.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:c="http://www.springframework.org/schema/c"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/aop
        https://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
        https://www.springframework.org/schema/mvc/tx.xsd">
    <!--1.扫描service下的包-->
    <context:component-scan base-package="com.ji.service"/>
    <import resource="spring-dao.xml"/>
    <!--2.将我们的所有业务类注入到spring 可以通过配置-->
    <bean id="BookServiceImpl" class="com.ji.service.BookServiceImpl">
        <property name="booksMapper" ref="booksMapper"/>
    </bean>
    <!--3.声明式事务-->
    <bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager" id="transactionManager">
        <!--注入数据源-->
        <property name="dataSource" ref="datasource"/>
    </bean>
    <!--4.aop横切事务支持-->
    <!--<tx:advice id="txAdvice" transaction-manager="transactionManager">
        //给哪些方法配置事务
        //配置事务的传播特性
        <tx:attributes>
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>
    //配置事务切入
    <aop:config>
        <aop:pointcut id="pointCut" expression="execution(* com.ji.dao.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut"/>
    </aop:config>-->
</beans>

Bookservice层接口

package com.ji.service;

import com.ji.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookService {
    //增加
    int addBook(Books books);
    //删除
    int deleteBooks(int id);
    //更改
    int updateBooks(Books books);
    //查询一本书
    Books queryBooks(int id);

    List<Books> queryAllBooks();

    List<Books> queryBookByName(String bookName);
}

BookService实现类

package com.ji.service;

import com.ji.dao.BooksMapper;
import com.ji.pojo.Books;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.List;

public class BookServiceImpl implements BookService{
    //service层调用dao层，组合dao
    private BooksMapper booksMapper;

    public BooksMapper getBooksMapper() {
        return booksMapper;
    }
    public void setBooksMapper(BooksMapper booksMapper) {
        this.booksMapper = booksMapper;
    }

    public int addBook(Books books) {
        return booksMapper.addBook (books);
    }

    public int deleteBooks(int id) {
        return booksMapper.deleteBooks (id);
    }

    public int updateBooks(Books books) {
        return booksMapper.updateBooks (books);
    }

    public Books queryBooks(int id) {
        return booksMapper.queryBooks (id);
    }

    public List<Books> queryAllBooks() {
        return booksMapper.queryAllBooks ();
    }

    public List<Books> queryBookByName(String bookName) {
        return booksMapper.queryBookByName (bookName);
    }
}

8.配置（springmvc）
配置springmvc-servlet.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:c="http://www.springframework.org/schema/c"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        https://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--自动扫描包，让指定包下的注解生效，由ioc容器统一管理-->
    <context:component-scan base-package="com.ji.controller"/>
    <!--让springMVC不处理静态资源   .css .js .html .mp3 .mp4-->
    <mvc:default-servlet-handler/>
    <!--支持MVC注解驱动
    在spring中一般采用@RequestMapping注解来完成映射关系
    要想使@RequestMapping注解生效
    必须向上下文中注册DefaultAnnotationHandlerMapping
    和一个AnnotationMethodHandlerAdapter实例
    和两个实例分别在类级别和方法级别处理
    而annotation-driven配置帮助我们自动完成上述两个实例的注入-->
    <mvc:annotation-driven/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

配置整合三层的xml文件的总文件
ApplicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:c="http://www.springframework.org/schema/c"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        https://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <context:annotation-config/>
    <import resource="spring-service.xml"/>
    <import resource="spring-dao.xml"/>
    <import resource="springmvc-servlet.xml"/>

</beans>

配置web/WEB-INF目录下的web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<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"
         version="4.0">
<!--配置dispatcherServlet，这个是springmvc的核心，请求分发器，前端控制器-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
              <!--要绑定springMVC的配置文件  加载的是总的配置文件-->
            <param-value>classpath:ApplicationContext.xml</param-value>
        </init-param>
          <!--启动级别 1服务器启动就启动-->
        <load-on-startup>1</load-on-startup>
    </servlet>
 <!--
    /  只匹配所有的请求不会匹配jsp页面
    /* 既匹配所有的请求也会匹配jsp页面  //可能会造成无限jsp循环-->
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--配置过滤器过滤乱码问题-->
    <filter>
        <filter-name>encoding</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>

        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

9.编写Controller层

package com.ji.controller;

import com.ji.pojo.Books;
import com.ji.service.BookService;
import com.ji.service.BookServiceImpl;
import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.ArrayList;
import java.util.List;

@Controller
@RequestMapping("/book")
public class BookController {
    //controller层调用service层

    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;
    //查询全部书记，并返回一个书籍展示页面
    @RequestMapping("/allBook")
    public String list(Model model)
    {
        List<Books> list=bookService.queryAllBooks ();
        model.addAttribute ("list",list);
        return "allBooks";
    }
    //跳转到增加书籍页面
    @RequestMapping("/toAddBook")
    public String toAddPaper()
    {
        return "addBook";
    }

    //添加书籍请求
    @RequestMapping("/addBook")
    public String addBook(Books books)

        line-height: 38px;
        background: deeppink;
        border-radius: 10px;
      }
    </style>
  </head>
  <body>

注意
引入新jar包时，需要将jar打包到war包中
文件-》项目结构-》artifacts
在WEB-INF下新建web目录将所用jar包导入
