SSM框架整合---简易书籍管理系统

作者:互联网

学习完Spring+SpringMVC+MyBatis ,我们需要用一个项目来整合SSM框架,这里我们用一个简易的书籍管理系统来整合SSM框架,并回顾Spring+SpringMVC+MyBatis的内容。

注:本篇文章参考于B站狂神说老师的视频,原视频地址【狂神说Java】SpringMVC最新教程IDEA版通俗易懂,如有遗漏和错误欢迎大家提出!!!

1、环境准备

1.1、环境要求

idea 2020.3+MySql 8.0.29+maven 3.5.2

前端:jsp+css+bootstrap

1.2、搭建数据据库环境

创建一个存放书籍数据的数据库表

CREATE DATABASE ssmbuild;
USE ssmbuild;
CREATE TABLE `books`(
`bookID` INT NOT NULL AUTO_INCREMENT COMMENT '书id',
`bookName` VARCHAR(100) NOT NULL COMMENT '书名',
`bookCounts` INT 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')

数据库表如图:

2、基本环境搭建

2.1、新建普通Maven项目,添加web的支持

2.2、导入依赖

常用的依赖:junit,数据库驱动,连接池,servlet,jsp,mybatis,mybatis-spring,spring,lombok

<!-- 依赖: junit,数据库驱动,连接池,servlet,jsp,mybatis,mybatis-spring,spring-->

            <version>1.18.12</version>
        </dependency>

    </dependencies>

2.3、Maven资源过滤问题设置

<!--静态资源导出-->
<!--maven静态资源过滤问题-->
<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>

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

</build>

2.4、maven扫描xml文件编码问题

少数人会遇这个问题
java 解决异常 2 字节的 UTF-8 序列的字节2 无效的问题

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

2.5、建立基本结构和配置框架

3、Mybatis层编写

3.1、编写数据库配置文件database.properties

jdbc.driver=com.mysql.cj.jdbc.Driver
# 如果使用的是mysql8.0+版本的,需要增加一个时区的配置&serverTimezone=Asia/Shanghai
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai
jdbc.username=root
jdbc.password=qjd011212

3.2、编写MyBatis的核心配置文件

<?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>
    <settings>
        <!--配置日志 在控制台输出 有点多,可不加-->
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>

    <!--配置数据源,交给Spring去做-->

    <!--起别名-->
    <typeAliases>
        <package name="com.qjd.pojo"/>
    </typeAliases>

    <mappers>
        <mapper class="com.qjd.dao.BookMapper"/>
    </mappers>


</configuration>

3.3、编写实体类

这里为了简化代码使用lombok插件

@Data                  //除了有参构造都加入了(set,get,toString...)
@AllArgsConstructor    //加入有参构造,无参构造就没有了,需要加入@NoArgsConstructor无参构造
@NoArgsConstructor
public class Books {
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
}

3.4、编写Dao层

3.4.1、编写Dao层的Mapper接口

public interface BookMapper {

    //增加一本书
    int addBook(Books books);

    //删除一本书
    int deleteBookById(@Param("bookId") int id);

    //更新一本书
    int updateBook(Books books);

    //查询一本书
    Books queryBookById(@Param("bookId") int id);

    //查询所有书
    List<Books> queryAllBook();

    //根据书籍名称模糊查询
    List<Books> queryBookName(@Param("keyword") String keyword);

}

3.4.2、编写Mapper接口对应的Mapper.xml

一个Mapper.xml对应一个Mapper接口,要用namespace绑定上述接口 需要导入MyBatis的包!

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.qjd.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="queryBookName" resultType="Books">
        select * from ssmbuild.books where bookName like concat( #{keyword},'%')
    </select>
</mapper>

3.5、编写Service层

3.5.1、编写Service层的接口

public interface BookService {
    //增加一本书
    int addBook(Books books);

    //删除一本书
    int deleteBookById(int id);

    //更新一本书
    int updateBook(Books books);

    //查询一本书
    Books queryBookById(int id);

    //查询所有书
    List<Books> queryAllBook();

    //根据书籍名称模糊查询
    List<Books> queryBookName(String keyword);

}

3.5.2、编写Service层的接口实现类

public class BookServiceImpl implements BookService {
    //service 调dao层:组合Dao
    private BookMapper bookMapper;

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

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

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

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

    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

    public List<Books> queryAllBook() {
        return bookMapper.queryAllBook();
    }

    public List<Books> queryBookName(String keyword) {
        return bookMapper.queryBookName(keyword);
    }

}

OK,到此,底层需求操作编写完毕!

4、Spring层编写

4.1、Spring整合Dao层

在resource目录下新建spring-dao.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: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">

    <!--1.关联数据库配置文件(这里需要导入xmlns:context)-->
    <context:property-placeholder location="classpath:database.properties"/>

    <!--2.配置c3p0连接池
       数据库连接池
       dbcp 半自动化操作 不能自动连接
       c3p0 自动化操作(自动的加载配置文件 并且设置到对象里面)
       druid
       hikari
    -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置连接池属性 -->
        <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连接池的私有属性 -->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <!-- 关闭连接后不自动commit -->
        <property name="autoCommitOnClose" value="false"/>
        <!-- 获取连接超时时间 -->
        <property name="checkoutTimeout" value="10000"/>
        <!-- 当获取连接失败重试次数 -->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>

    <!--3.sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--绑定Mybatis的配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

    <!-- 4.配置扫描Dao接口包,动态实现Dao接口注入到spring容器中 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 给出需要扫描Dao接口包 -->
        <property name="basePackage" value="com.qjd.dao"/>
    </bean>

</beans>

1、关联数据库配置文件db.properties,要引入context约束

2、配置MyBatis数据源,这里使用第三方的c3p0,还可以附加一些私有属性

3、创建sqlSessionFactory,在 MyBatis-Spring 中,则使用 SqlSessionFactoryBean 来创建,要配置两个重要属性

configLocation绑定MyBatis核心配置文件
dataSource指定数据源(必要)
4、配置自动扫描包dao,动态实现了dao层接口可以注入到Spring容器中

(在原来我们是创建sqlSessionTemplate对象,然后再创建一个Mapper接口实现类,其中内置sqlSessionTemplate私有对象,通过该对象进行操作)

Java连接池

在Java中开源的数据库连接池有以下几种:
1、C3P0:是一个开放源代码的JDBC连接池,它在Iib目录中与Hibernate一起发布,包括了实现jdbc3和jdbc2扩展规范
说明的Connection和Statement池的DataSources对象。
2、Proxool::是一个Java SQL Driver驱动程序,提供了对选择的其它类型的驱动程序的连接池封装。可以非常简单的移植到
现存的代码中,完全可配置,快速、成熟、健壮。可以透明地为现存的JDBC驱动程序增加连接池功能。
3、Jakarta DBCP:DBCP是一个依赖Jakartacommons-pool对象池机制的数据库连接池。DBCP可以直接的在应用程序中使
用。
4、DDConnectionBroker:是一个简单、轻量级的数据库连接池。
5、DBP00:是一个高效、易配置的数据库连接池。它除了支持连接池应有的功能之外,还包括了一个对象池,使用户能够
开发一个满足自己需求的数据库连接池。
6、XAPool:是一个XA数据库连接池。它实现了javax.sql.XADataSource并提供了连接池工具。

4.2、Spring整合service层

在resource目录下新建spring-service.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: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">

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

    <!--2.将我们的所有业务类,注入到Spring,可以通过配置,或者注解实现(@Service  @Autowired)-->
    <bean id="BookServiceImpl" class="com.qjd.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

    <!--3.声明式事务配置-->
    <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! 暂时不用-->

</beans>

Spring层的编写我们就搞定了!

4.3、对底层Dao进行测试

首先将配置文件整合到application.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"
       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"/>

</beans>

在test包下的java包下新建一个类MyTest.java 这里使用Junit 单元测试框架

public class MyTest {
    @Test
    public void test1(){
        ApplicationContext context = new ClassPathXmlApplicationContext("application.xml");
        BookService bookServiceImpl = (BookService) context.getBean("BookServiceImpl");
        for (Books books : bookServiceImpl.queryAllBook()) {
            System.out.println(books);
        }
    }
}

测试结果:

测试成功证明我们的底层代码没有问题! 我们开始SpringMVC层的编写吧~

5、SpringMVC层编写

5.1、配置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">
    <!--DispatcherServlet-->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!--一定要注意:我们这里加载的是总的配置文件,之前被这里坑了!-->
            <param-value>classpath:application.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--乱码过滤encodingFilter-->
    <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过期时间-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>


</web-app>

5.2、编写spring-mvc.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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       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 http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.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.qjd.controller"/>
    <!--4.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>

5.3、Spring整合配置文件

application.xml中 整合dao层的spring-dao.xml、service层的spring-service.xml和SpringMVC层的spring-mvc.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"
       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>

通过整合Spring可以用于团队开发!

配置文件,暂时结束!我们开始Controller 和 视图层编写了~

5.4、编写Controller

BookController中实现了5个业务

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

    @Autowired
    @Qualifier("BookServiceImpl") //用来指定别名
    private BookService bookService;

    //查询全部书籍,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";
    }

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

    //新增书籍的请求(点击添加让它添加成功)
    @RequestMapping("/addBook")
    public String addPaper(Books books) {
        System.out.println("addBook==>" + books);
        bookService.addBook(books);
        return "redirect:/book/allBook";
    }

    //跳转到修改书籍页面
    @RequestMapping("/toUpdateBook")
    public String toUpdateBook(Model model, int id) {
        Books books = bookService.queryBookById(id);
        System.out.println("toUpdateBook==>" + books);
        model.addAttribute("book", books);
        return "updateBook";
    }

    //修改书籍
    @RequestMapping("/updateBook")
    public String updateBook(Model model, Books book) {
        System.out.println("UpdateBook==>" + book);
        bookService.updateBook(book);
        Books books = bookService.queryBookById(book.getBookID());
        model.addAttribute("books", books);
        return "redirect:/book/allBook";
    }

    //删除书籍 RestFul风格回顾
    @RequestMapping("/del/{bookId}")
    public String deleteBook(@PathVariable("bookId") int id) {
        bookService.deleteBookById(id);
        return "redirect:/book/allBook";
    }

    //根据书籍名称模糊查询书籍
    @RequestMapping("/queryBook")
    public String queryBook(String keyword, Model model) {
        List<Books> list = bookService.queryBookName(keyword);
        System.err.println("queryBook=>" + list);
        if (list.isEmpty()) {
            list = bookService.queryAllBook();
            model.addAttribute("error", "未查到该书籍");
        }

        model.addAttribute("list", list);
        return "allBook";

    }
}

5.5、编写视图层

<!--4.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>

根据我们定义的前缀和后缀在web/WEB-INF/目录下新建jsp包,用来存放我们自定义视图页面

5.5.1、编写首页 index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>首页</title>
    <style type="text/css">
      a {
        text-decoration: none;
        color: black;
        font-size: 18px;
      }
      h3 {
        width: 180px;
        height: 38px;
        margin: 100px auto;
        text-align: center;
        line-height: 38px;
        background: deepskyblue;
        border-radius: 4px;
      }
    </style>
  </head>
  <body>
  <h3>
    <a href="${pageContext.request.contextPath}/book/allBook">点击进入书籍展示页</a>
  </h3>
  </body>
</html>
