2021-09-18 18:59:15  阅读：144  来源： 互联网

标签：管理系统 int 书籍 SSM Books books import public 


环境要求
  • IDEA
  • MySQL 5.0以上版本
  • tomcat 9
  • maven 3.6
数据库环境

建立一个存放书籍信息的数据库表

CREATE DATABASE `ssm`;

CREATE TABLE `books`(
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
`bookName` VARCHAR(100) NOT NULL COMMENT '书名',
`bookCounts` INT(30) 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',5,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',12,'从进门到坐牢');

基本环境搭建

1，新建空的maven项目，添加web支持。
2，导入相关依赖。

           <artifactId>mybatis-spring</artifactId>
           <version>2.0.5</version>
       </dependency>
   </dependencies>

3,资源过滤设置

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

4,建立基本结构和配置框架。
在这里插入图片描述

Mybatis层编写

1，数据库配置文件database.properties

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?useSSl=true&useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=123456

2,idea关联数据库
3，编写myBatis的核心配置文件

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<!--核心配置文件-->
<configuration>

<!--    配置数据源，这里交给Spring去做-->
    
    <typeAliases>
        <package name="com.tt.pojo"/>
    </typeAliases>
    
</configuration>

4,编写数据库对应的实体类，com.tt.pojo.Books(这里使用了LomBok插件)

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
}

5,编写Dao层接口BookMapper

package com.tt.dao;

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

import java.util.List;

public interface BookMapper {
    //增加一本书
    int addBook(Books books);
    //删除一本书
    int deleteBookById(@Param("bookId") int id);
    //查询一本书
    Books queryBooksById(@Param("bookId") int id);
    //更新一本书
    int updateBook(Books books);
    //查询全部书籍
    List<Books> queryAllBooks();
    //根据书名查询书籍
    Books queryBookByName(@Param("bookName") String bookName);
}

6,编写对应的Mapper.xml映射文件

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--mybatis核心配置文件-->
<mapper namespace="com.tt.dao.BookMapper">

<insert id="addBook" parameterType="Books">
    insert into ssm.books(bookName,bookCounts,detail)
        value (#{bookName},#{bookCounts},#{detail})
</insert>

    <delete id="deleteBookById" parameterType="int">
        delete from ssm.books where bookID=#{bookId}
    </delete>

    <update id="updateBook" parameterType="Books">
        update ssm.books set  bookName= #{bookName},
        bookCounts= #{bookCounts},
        detail=#{detail}
        where BookID= #{bookID}
    </update>

    <select id="queryBooksById" resultType="Books">
        select * from ssm.books
        where bookID= #{bookId}
    </select>

    <select id="queryAllBooks" resultType="Books">
        select * from ssm.books
    </select>

    <select id="queryBookByName" resultType="Books">
        select * from ssm.books where bookName=#{bookName}
    </select>


</mapper>

7,编写service业务层接口

package com.tt.service;

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

import java.util.List;

public interface BookService {
    //增加一本书
    int addBook(Books books);
    //删除一本书
    int deleteBookById(int id);
    //查询一本书
    Books queryBooksById(int id);
    //更新一本书
    int updateBook(Books books);
    //查询全部书籍
    List<Books> queryAllBooks();
    //根据书名查询书籍
    Books queryBookByName( String bookName);
}

8,业务层接口实现类

package com.tt.service;

import com.tt.dao.BookMapper;
import com.tt.pojo.Books;

import java.util.List;

public class BookServiceImpl implements BookService{

    //service调用dao层

    private BookMapper bookMapper;

    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

    @Override
    public int addBook(Books books) {
        return bookMapper.addBook(books);
    }

    @Override
    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }

    @Override
    public Books queryBooksById(int id) {
        return bookMapper.queryBooksById(id);
    }

    @Override
    public int updateBook(Books books) {
        return bookMapper.updateBook(books);
    }

    @Override
    public List<Books> queryAllBooks() {
        return bookMapper.queryAllBooks();
    }

    @Override
    public Books queryBookByName(String bookName) {
        return bookMapper.queryBookByName(bookName);
    }
}

到此，底层操作编写完毕

Spring层

1，配置spring整合mybatis;这里数据源用c3p0连接池。
2，编写spring整合mybatis的配置文件：spring-dao.xml

<?xml version="1.0" encoding="UTF8"?>
<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
        https://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">


<!--    关联数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>


<!--    数据库连接池-->
    <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}"/>
<!--        c3p0的私有属性-->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
<!--        关闭连接后不自动提交事务-->
        <property name="autoCommitOnClose" value="false"/>
<!--        获取连接超时时间-->
        <property name="checkoutTimeout" value="10000"/>
<!--        当获取连接失败后重试次数-->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>

<!--    sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--绑定mybatis配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

<!--    配置dao接口扫描包，动态实现dao接口可以注入到Spring容器中-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <!-- 注入sqlSessionFactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    <!--  要扫描的包      -->
        <property name="basePackage" value="com.tt.dao"/>
    </bean>
</beans>

3,spring整合service spring-service.xml

<?xml version="1.0" encoding="UTF8"?>
<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
        https://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">


<!--    1,    扫描service下的包-->
    <context:component-scan base-package="com.tt.service"/>

<!--   2,   将所有的业务类注入到Spring中，可以通过配置，或者注解实现 -->
   <bean id="BookServiceImpl" class="com.tt.service.BookServiceImpl">
       <property name="bookMapper" ref="bookMapper"/>
   </bean>

<!--  3,  声明式事务管理  -->

    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!--        注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>

<!--    4,aop事务支持-->
</beans>

spring层到此结束，它是一个容器，可以整合多个配置文件

springMVC层

1，编写web.xml

<?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">

<!--    注册DispatcherServlet-->
    <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:applicationContext.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>


<!--    乱码过滤-->
    <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>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

  <session-config>
      <session-timeout>15</session-timeout>
  </session-config>
</web-app>

2,spring-mvc.xml

<?xml version="1.0" encoding="UTF8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

    <!--1,注解驱动-->
<mvc:annotation-driven/>
    <!--  2,  静态资源过滤-->
<mvc:default-servlet-handler/>
<!--    3,扫描包：controller-->
    <context:component-scan base-package="com.tt.controller"/>
<!--    视图解析器-->
    <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

<?xml version="1.0" encoding="UTF8"?>
<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
        https://www.springframework.org/schema/beans/spring-beans.xsd">

<!--    将dao和service关联起来-->
    <import resource="classpath:spring-dao.xml"/>
    <import resource="classpath:spring-service.xml"/>
    <import resource="classpath:spring-mvc.xml"/>
</beans>

配置文件，基本结束

Controller和视图层编写

1，BookController类编写，

package com.tt.controller;


import com.tt.pojo.Books;
import com.tt.service.BookService;
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.web.bind.annotation.RequestMapping;

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

@Controller
@RequestMapping("/book")
public class BookController {
    //调用业务层
    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;

    //查询全部书籍
    @RequestMapping("/allBook")
    public String list(Model model){
        List<Books> list = bookService.queryAllBooks();
        model.addAttribute("list",list);
        return "allBook";
    }

    //跳转到新增书籍页面
    @RequestMapping("/toAddPage")
    public String toAddPage(){
        return "addBook";
    }

    //添加书籍功能实现
    @RequestMapping("/addBook")
    public String addBook(Books books){
     bookService.addBook(books);
     return "redirect:/book/allBook";
    }

    //跳转到修改书籍页面
    @RequestMapping("/updatePage")
    public String toUpdatePage(int id,Model model){
        Books books = bookService.queryBooksById(id);
        model.addAttribute("QBooks",books);
        return "updateBook";
    }

    //修改书籍功能实现
    @RequestMapping("updateBook")
    public String updateBook(Books books){
        bookService.updateBook(books);
        return "redirect:/book/allBook";
    }

    //删除书籍功能实现
    @RequestMapping("/deleteBook")
    public String deleteBook(int id){
        bookService.deleteBookById(id);
        return "redirect:/book/allBook";
    }

    //查询书籍
    @RequestMapping("/queryBook")
    public String queryBook(String queryBookName,Model model){
        Books books = bookService.queryBookByName(queryBookName);
        List<Books> list = new ArrayList<>();
        list.add(books);
        if(books==null){
            list=bookService.queryAllBooks();
            model.addAttribute("error","未查询到该书籍");
        }
        model.addAttribute("list",list);
        return "allBook";
    }
}

2，首页视图，index.jsp


<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>首页</title>
    <style>
      a{

        font-size: 25px;
      }
      h3{

        background: aquamarine;
        border-radius: 5px;
      }
    </style>
  </head>
  <body>
 <h3>
   <a href="${pageContext.request.contextPath}/book/allBook">进入书籍页面</a>
 </h3>
  </body>
</html>

3,全部书籍页面，allBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
