1.搭建整合ssm框架项目并提交项目源码。

环境

IDEA
Mysql
Tomcat 8
Maven

数据库环境

1.新建数据库

CREATE DATABASE `ssmbuild`;

2.建表及插入数据

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for books
-- ----------------------------
DROP TABLE IF EXISTS `books`;
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 AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of books
-- ----------------------------
INSERT INTO `books` VALUES ('1', 'Java', '1', '一个BUG改一天');
INSERT INTO `books` VALUES ('2', 'MySQL', '10', '增删改查');
INSERT INTO `books` VALUES ('3', 'Linux', '5', '从进门到进牢');
INSERT INTO `books` VALUES ('4', 'SpringMVC', '6', '从入门到放弃');

3.项目环境搭建
3.1新建Maven项目（ssmbuild），

右击项目名选择第二个，添加web支持
在这里插入图片描述
3.2 在pom.xml配置文件中导入依赖
依赖导入 Junit,数据库驱动，连接池，servlet，jsp，mybaits,mybatis-spring,spring等
直接拷贝：

package com.yu.dao;

import com.yu.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookMapper {
    //增加一本书
    public int insertBook(Books books);
    //删除书籍
    public int deleteBook(@Param("bookId") int id);

    //更新一本书
    public int updateBook( int id);

package com.yu.service;

import com.yu.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookService {

    //增加一本书
    public int insertBook(Books books);
    //删除书籍
    public int deleteBook(int id);

    //更新一本书
    public int updateBook( int id);

public class BookServiceImpl implements BookService{

    //service层调用到层，
    private BookMapper bookMapper;
    //利用set方式，方便交给spring托管
    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

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

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

    public int updateBook(int id) {
        return bookMapper.updateBook(id);

以上是Mybatis层的配置

整合Spring层

编写Spring整合Mybatis的相关的配置文件；spring-dao.xml

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

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
