SSM整合项目

一、环境搭建与SSM整合

1、创建数据库表

CREATE DATABASE `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');

2、创建Maven项目

①新建Maven项目，添加web支持。

②导入依赖

<!--依赖：junit,数据库驱动，连接池，servlet,jsp,mybatis,mybatis-spring,spring-->
    <dependencies>
        <!--junit-->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
        <!--数据库驱动-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.47</version>
        </dependency>
        <!--数据库连接池:c3p0:dbcp-->
        <dependency>
            <groupId>com.mchange</groupId>
            <artifactId>c3p0</artifactId>
            <version>0.9.5.2</version>
        </dependency>
        <!--Servlet-JSP-->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
            <version>2.5</version>
        </dependency>
        <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.2</version>
        </dependency>
        <dependency>
            <groupId>javax.servlet.jsp.jstl</groupId>
            <artifactId>jstl-api</artifactId>
            <version>1.2</version>
        </dependency>

        <!--Mybatis-->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>3.5.2</version>
        </dependency>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>2.0.2</version>
        </dependency>

        <!--Spring-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>5.1.9.RELEASE</version>
        </dependency><!--Spring操作数据库，还需要一个spring-jdbc-->
        <!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>5.1.9.RELEASE</version>
        </dependency>

        <dependency>

            <artifactId>lombok</artifactId>
            <version>1.18.10</version>
        </dependency>

    </dependencies>

④处理静态资源导出问题

 <!--静态资源导出问题-->
    <build>
      <resources>
        <resource>
            <directory>src/main/resources</directory>
            <excludes>
                <exclude>**/*.properties</exclude>
                <exclude>**/*.xml</exclude>
             </excludes>
            <filtering>false</filtering>
        </resource>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
</build>

⑤创建项目结构

image-20210823173304941

mybatis-config.xml

<?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-->
<configuration>

</configuration>

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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd">

</beans>

3、Mybatis层

①数据库配置文件database.properties

jdbc.driver = com.mysql.jdbc.Driver
#如果使用的是MySQL8.0+，增加一个时区的配置。 &serverTimezone=Asia/Shanghai
jdbc.url = jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = root

②mybatis-config.xml取别名

<typeAliases>
        <package name="com.darkerg.pojo"/>
    </typeAliases>

③创建实体类Books

package com.darkerg.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;

}

④在dao层创建与之对应的接口和增删改查，并注册。

BookMapper接口

package com.darkerg.dao;

import com.darkerg.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);
    //更新一本书
    int updateBook(Books books);
    //查询一本书
    Books queryBookById(@Param("bookId") int id);
    //查询全部的书
    List<Books> queryAllBook();

}

BookMapper.xml与接口对应的配置文件，实现增删改查

<?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">
<!--namespace=绑定一个队形的Dao/mapper接口-->
<mapper namespace="com.darkerg.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>

在Mybatis的配置文件中注册

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

Service业务层

①创建BookService接口

package com.darkerg.service;

import com.darkerg.pojo.Books;

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);
    //更新一本书
    int updateBook(Books books);
    //查询一本书
    Books qeuryBookById(int id);
    //查询全部的书
    List<Books> queryAllBook();

}

②编写其实现类BookServiceImpl

package com.darkerg.service;

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

import java.util.List;

public class BookServiceImpl implements BookService{

    //service层掉dao层：组合Dao层
    private BookMapper bookMapper;

    //过会儿交给Spring托管
    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 qeuryBookById(int id) {
        return bookMapper.qeuryBookById(id);
    }

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

4、Spring层

①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">

    <!--关联数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>
    <!--连接池
        dbcp:   半自动化操作，不能自动连接
        c3p0:   自动化操作（自动化的加载配置文件，斌企鹅可以自动设置到对象中。
        druid:
        hikari:
    -->
    <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="acquireIncrement" value="2"/>
    </bean>

    <!--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>

    <!--配置dao接口扫描包，动态的实现了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dao包-->
        <property name="basePackage" value="com.darkerg.dao"/>
    </bean>



</beans>

此处c3p0如果有问题的话，就换成Spring自带的。

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

②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">


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

    <!--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-->
    <bean id="BookServiceImpl" class="com.darkerg.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

    <!--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>

    <!--AOP横切事务支持-->

</beans>

5、SpringMVC层

①添加Web支持

②编写web.xml文件

在这之前需要新建一个spring-mvc.xml的文件

然后再把这些xml文件都整合到applicationContext.xml中

<import resource="classpath:spring-dao.xml"/>
<import resource="classpath:spring-service.xml"/>
<import resource="classpath:spring-mvc.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>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-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>

</web-app>

③编写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"
       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">


    <!--注解驱动-->
    <mvc:annotation-driven/>
    <!--静态资源过滤-->
    <mvc:default-servlet-handler/>
    <!--扫描包：controller-->
    <context:component-scan base-package="com.darkerg.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>

④在WEB-INF下创建jsp目录

二、查询书籍功能

1、新建BookController控制器

package com.darkerg.controller;

import com.darkerg.pojo.Books;
import com.darkerg.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.List;

@Controller
@RequestMapping("/book")
public class BookController {

    //Controller层调Service层
    @Autowired
    @Qualifier("BookServiceImpl")
    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、index.jsp

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

    <style>
      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: 5px;
      }
    </style>

  </head>
  <body>

  <h3>
    <a href="${pageContext.request.contextPath}/book/allBook">进入书籍页面</a>
  </h3>

  </body>
</html>

3、allBook.jsp

在这之前需要导入Standard依赖

<!-- https://mvnrepository.com/artifact/org.apache.taglibs/taglibs-standard-impl -->
        <dependency>
            <groupId>org.apache.taglibs</groupId>
            <artifactId>taglibs-standard-impl</artifactId>
            <version>1.2.5</version>
            <scope>runtime</scope>
        </dependency>

不要忘记重新在项目结构中，添加这个包，在Tomcat发布时候。

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

    <%--BootStrap美化界面，国内cdn连接。--%>
    <link href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>

<div class="container">

    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    <small>书籍列表 —————— 显示所有书籍</small>
                </h1>
            </div>
        </div>
    </div>

    <div class="row clearfix">
        <div class="col-md-12 column">
            <table class="table table-hover table-striped">
                <thead>
                    <tr>
                        <th>书籍编号</th>
                        <th>书籍名称</th>
                        <th>书籍数量</th>
                        <th>书籍详情</th>
                    </tr>
                </thead>

                <%--书籍从数据库中查询出来,从list中遍历出来：foreach--%>
                <tbody>
                    <c:forEach var="book" items="${list}">
                        <tr>
                            <td>${book.bookID}</td>
                            <td>${book.bookName}</td>
                            <td>${book.bookCounts}</td>
                            <td>${book.detail}</td>
                        </tr>
                    </c:forEach>
                </tbody>
            </table>
        </div>

    </div>

</div>


</body>
</html>

三、添加书籍功能

1、index.jsp

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

    <style>
      a{
          text-decoration: none;
          color: black;
          font-size: 18px;
      }

@Controller
@RequestMapping("/book")
public class BookController {

    //Controller层调Service层
    @Autowired
    @Qualifier("BookServiceImpl")
    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);
