本文详细介绍了如何新建一个SSM项目，包括配置Maven镜像和仓库，引入必要的依赖，如MyBatis、Spring等，以及数据库连接、实体类映射、Mapper接口和XML、Service层实现、Spring配置、静态资源管理，最后展示了Controller和页面展示的实例。

1、新建项目，把maven的配置文件（阿里镜像）跟仓库路径都改为自己的
在这里插入图片描述
2、在Pom.xml导入ssm框架所需依赖、解决静态资源导出问题。

            <version>1.18.20</version>
        </dependency>
    </dependencies>

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

</project>

3、新建mybatis-config.xml文件，这里只用配置mybatis的基本设置，例如起别名和实体类映射路径，配置数据源交给Spring去做。

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!--配置数据源，交给spring去做-->
    <typeAliases>
    <package name="com.hang.pojo"/>
    </typeAliases>

    <mappers>
        <mapper class="com.hang.mapper.BookMapper"/>
    </mappers>
</configuration>

4、新建一个数据库实体类

package com.hang.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、新建一个实体类接口和Mpper.xml文件操作数据库执行增删改查语句。

①实体类接口

package com.hang.mapper;

import com.hang.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();
}

②mapper.xml

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.hang.mapper.BookMapper">
    <insert id="addBook" parameterType="Books">
        insert into ssmbuid.books(bookName,bookCounts,detail)
        values (#{bookName},#{bookCounts},#{detail});
    </insert>
    
    <delete id="deleteBookById" parameterType="int">
        delete from ssumbid.book where  bookID = #{bookId}
    </delete>

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

    <select id="queryBookById" resultType="Books">
        select * from ssmbuid.books 
        where bookID = #{bookID}
    </select>

    <select id="queryAllBook" resultType="Books">
        select * from ssmbuid.books
    </select>

</mapper>

6、新建service层调用mapper层的实体类接口。
在这里插入图片描述
①service

package com.hang.service;

import com.hang.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 queryBookById(int id);

    //查询全部的书
    List<Books> queryAllBook();
}

②serviceImpl

package com.hang.service;

import com.hang.mapper.BookMapper;
import com.hang.pojo.Books;

import java.util.List;

public class BookServiceImpl implements BookService{

    //Service调Dao层：组合Dao层
    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();
    }
}

7、新建database.properties数据库配置文件（注意数据库用户名跟密码用自己的）

jdbc.driver=com.mysql.jdbc.Driver
#如果是使用的是mysql8.0+，需要增加一个时区的配置 &serverTimeZone=Asia/Shanghai,8.0+以上的驱动类需要加上'cj'
jdbc.url=jdbc:mysql://localhost:3306/ssmbuid?useSSL=false&useUnicode=true&characterEncoding=utf8
jdbc.username=****
jdbc.password=****

8、新建Spring-mapper.xml关联数据库配置文件、配置数据源连接池（我这里用的是c3p0连接池）、绑定mybatis的配置文件（这里就是上面的mybstis-config.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:contxt="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.关联数据库配置文件-->
    <contxt:property-placeholder location="classpath:database.properties"/>

    <!--2.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，并且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="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mapper接口扫描包，动态实现了mapper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mapper的包-->
        <property name="basePackage" value="com.hang.mapper"/>
    </bean>

9、新建spring-mvc.xml注解驱动、解决静态资源过滤和扫描包（控制器层），配置视图解析器。

<?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.hang.controller"/>

    <!--4.视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--前缀-->
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <!--后缀-->
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

10、新建Spring-service.xml扫描Service下的包，将我们的所有业务类注入到Spring、配置声明式事务。

<?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.hang.service"/>

    <!--2.将我们的所有的业务类，注入到Spring，可以通过配置或者注解实现-->
    <bean id="BookServiceImpl" class="com.hang.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横切事务支持-->

</beans>

11、新建applicationContext.xml引入以上三个spring配置文件

<?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">

    <import resource="classpath:spring-mapper.xml"/>
    <import resource="classpath:spring-service.xml"/>
    <import resource="classpath:spring-mvc.xml"/>

</beans>

12、新建controller控制器层执行方法。

package com.hang.controller;

import com.hang.pojo.Books;
import com.hang.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 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";
    }
    //跳转到增加书籍页面
    @RequestMapping("/toAddBook")
    public String toAddPaper(){
        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;
    }

}

13、配置Web.xml引用DispatcherServlet包、解决页面乱码问题、设置Session过期时间。

<?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>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>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--Session过期时间-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>
</web-app>

14、在index.jsp中配置前端页面展示参数；

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

15、在WEB-INF下新建jsp文件夹，新建两个jsp文件实现页面展示详情。

addBook.jsp

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

    <%--BootStrap 美化界面--%>
    <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>新增书籍</small>
            </h1>
          </div>
        </div>

      </div>

    <form action="${pageContext.request.contextPath}/book/addBook" method="post">
      <div class="form-group">
        <label>书籍名称：</label>
        <input type="text" name="bookName" class="form-control" required>
      </div>
      <div class="form-group">
        <label>书籍数量：</label>
        <input type="text" name="bookCounts" class="form-control" required>
      </div>
      <div class="form-group">
        <label>书籍详情：</label>
        <input type="text" name="detail" class="form-control" required>
      </div>
      <div class="form-group">
          <input type="submit" class="form-control" value="添加">
      </div>
    </form>
  </div>

</body>
</html>

allBook.jsp

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

    <%--BootStrap 美化界面--%>
    <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 class="row">
                <div class="col-md-4 column">
                    <%--toaddBook--%>
                    <a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook">新增书籍</a>
                </div>
            </div>

        </div>
    </div>

    <div class="row_clearfix">
        <div class="col-md-12 column">
            <table class="table table-hover table-striped">
                <thead>
