##简述

今天主要讲诉一下ssm框架的搭建过程，由于springboot的广泛使用，很多人都忘记了怎么搭建ssm项目，这里做一个温习。

**demo地址：**https://github.com/LiJinHongPassion/ssmdemo2

目的

• 温习ssm框架
• 学习ssm框架，从而加深对springboot项目的灵活使用

准备

名称	版本
idea	2019
jdk	1.8
tomcat	8.5
maven	3.5
mysql	5.7

spring的请求方式

首先我们需要知道一个http请求是怎么经过spring的处理后得到响应的。

搭建

了解了请求的处理过程，下面开始搭建项目。

因为idea需要初始化项目索引，所以会导致很卡，会很吃内存。

配置ssm主要涉及到下面几个配置文件：

• spring-mvc.xml mvc配置
• spring-mybatis.xml 整合mybatis
• jdbc.properties 数据库连接池的属性配置
• web.xml

项目结构

这里项目结构不对，需要重新添加需要的文件夹，完成后如下：

添加依赖

修改pom.xml文件

    <spring.version>4.0.2.RELEASEspring.version>
    
    <mybatis.version>3.2.6mybatis.version>

spring-mvc.xml配置

添加依赖后，开始配置项目，先配置mvc

主要配置下面几个方面：

• 静态资源访问权限
• 开启注解
• 视图解析

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

#url=jdbc:mysql://127.0.0.1:3306/laboratory?useUnicode=true&characterEncoding=utf8
#url=jdbc:mysql://superc102.vicp.cc:3307/laboratory?useUnicode=true&characterEncoding=utf8
url=jdbc\:mysql\://127.0.0.1\:3306/financialtest?useUnicode\=true&characterEncoding\=utf8
username=root
password=root
#定义初始连接数
initialSize=1
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最大等待
maxWait=60000
#处理超时断开连接而没有销毁的情况
#验证查询语句
validationQuery=SELECT COUNT(*) FROM role
#周期性检测-半个小时
timeBetweenEvictionRunsMillis=1800000
#连接空闲时间 --半个小时
minEvictableIdleTimeMillis=1800000
#取得对象时是否进行验证，检查对象是否有效
testOnBorrow=true
#返回对象时是否进行验证，检查对象是否有效
testOnReturn=true
#空闲时是否进行验证，检查对象是否有效
testWhileIdle=true

web.xml配置

主要配置以下内容：

• spring容器
• 编码过滤器
• mvc分发器
• spring监听器
