Spring整合MyBatis(含监听器)

    Spring整合MyBatis首先要下载一个jar包：

        <dependency>
            <groupId>org.springframeworkgroupId>
            <artifactId>spring-webartifactId>
            <version>4.3.9.RELEASEversion>
        dependency>

<dependency>
    <groupId>org.mybatisgroupId>
    <artifactId>mybatis-springartifactId>
    <version>1.2.0version>
dependency>

<dependency>
    <groupId>org.mybatisgroupId>
    <artifactId>mybatisartifactId>
    <version>3.2.2version>
dependency>


<dependency>
    <groupId>mysqlgroupId>
    <artifactId>mysql-connector-javaartifactId>
    <version>5.1.31version>
dependency>

先建一个文件，在该文件中创建实体类eitity层，dao层，servic层，servlet层

首先在entity层中，创建一个Book实体类，并写上该类的属性值，将其进行get,set封装

public class Book {
    private Integer bookId;
    private String bookName;
    private int bookPrice;

之后就在dao层中创建一个BookDao接口，在该接口中写上一个实现方法。

   public interface BookDao {

           //添加

    public  int  add(Book book);
}

然后就该配置小配置BookDao.xml，当然也是在dao层，在这里需要注意的是接口名与小配置的名一致

xml version="1.0" encoding="UTF-8" ?>

 mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.happy.SpringSSM.dao.BookDao">
    <insert id="add">    //id是指接口中的实现方法名
        insert into book(bookname,bookprice) values(#{bookName},#{bookPrice})
    insert>
mapper>
接下来就到了service层了，在该层中也需要创建一个接口，该接口内中也要写上一个实现方法，该方法和dao层中的方法一致。
public interface BookService {
    public  int add(Book book);
}
接口写完之后，我们也需要在该层中写上一个BookServiceImpl类，在该类中实现BookService接口中的方法，并植入BookDao,将其进行封装
public class BookServiceImpl implements BookService {
      BookDao dao;

    public BookDao getDao() {
        return dao;
    }

    public void setDao(BookDao dao) {
        this.dao = dao;
    }

    public int add(Book book) {
        return dao.add(book);
    }
}
要想在页面中显示出来效果，重要的就靠servlet层中的了，当然在创建Servlet的时候一定要引包噢

<dependency>
    <groupId>javaeegroupId>
    <artifactId>javaee-apiartifactId>
    <version>5version>
dependency>


<dependency>
    <groupId>javax.servletgroupId>
    <artifactId>jstlartifactId>
    <version>1.2version>
    <scope>runtimescope>
dependency>

  接下来就到了很重要的环节了，配置阶段，在配置的时候会需要很多jar包，首先我们要先下载需要的jar包，将其放在pom.xml中

    <groupId>org.springframeworkgroupId>
    <artifactId>spring-beansartifactId>
    <version>4.2.3.RELEASEversion>

在创建一个bookadd.jsp页面

  切记不要忘了在web.xml中补全相关的信息
