SpringMVC-整合SSM框架（狂神学习笔记）2021-10-03

SpringMVC-狂神（整合SSM框架）

1、整合SSM

1. 环境要求

环境：

IDEA / Eclipse
MySQL 5.7 +
Tomcat 9
Maven 3.6

要求：
需要熟练掌握MySQL数据库，Spring，JavaWeb及MyBatis知识，简单的前端知识

2. 数据库环境

创建一个存放书籍数据的数据库表

CREATE DATABASE `ssmbuild`;

USE `ssmbuild`;

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 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');

3. 基本环境搭建

1. 新建一Maven项目！ssmbuild ， 添加web的支持
2. 导入相关的pom依赖 (版本个人自己选择)

<dependencies>
   <!--Junit-->
   <dependency>
       <groupId>junit</groupId>
       <artifactId>junit</artifactId>
       <version>4.12</version>
   </dependency>
   <!--数据库驱动-->

   </dependency>
   <!-- 数据库连接池 -->

       <artifactId>spring-jdbc</artifactId>

   </dependency>
</dependencies>

1. Maven资源过滤设置

<build>
   <resources>
       <resource>
           <directory>src/main/java</directory>
           <includes>
               <include>**/*.properties</include>
               <include>**/*.xml</include>
           </includes>
           <filtering>false</filtering>
       </resource
