Spring整合MyBatis(含监听器)

Spring整合MyBatis首先要下载一个jar包：

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>4.3.9.RELEASE</version>
        </dependency>

<!--MyBatis-Spring-->
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>1.2.0</version>
</dependency>

<!--mybatis核心jar包-->
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>3.2.2</version>
</dependency>

<!-- mysql配置-->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.31</version>
</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 interfaceBookDao {

//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" ?>
<!--头文件-->
<!DOCTYPE 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
<!--javaee的jar包-->
<dependency>
    <groupId>javaee</groupId>
    <artifactId>javaee-api</artifactId>
    <version>5</version>
</dependency>

<!--jsp进行循环迭代数据，使用jstl-->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
    <scope>runtime</scope>
</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

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
