SSM框架_V1
更新于(2018-7-14 16:06:43)
1、动机
SSM(Spring+SpringMVC+MyBatis)框架集由Spring、SpringMVC、MyBatis三个开源框架整合而成。
不知不觉学了SSM框架已经三个多月了，回顾之前整合的文章，发现了很多不足，有很多可以改进的地方。因此抽出了一天时间重新整理SSM框架整合笔记。
SSM框架_V1 - [基础版] 满足入门需求！
项目地址：https://gitee.com/qq343509740/SSM_Final/tree/master/SSM_Final_V1
2、搭建
Maven创建web项目：https://blog.csdn.net/q343509740/article/details/79509261
3、配置pom和web
3.1、pom.xml
Maven引入JAR包（详细说明），集成SSM + Druid + Log4j2。

4.1、jdbc.properties
数据库配置文件（详细说明），作用：解耦
# Mysql
## 数据库驱动
jdbc.driver=com.mysql.jdbc.Driver
## 数据库地址
jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8
## 数据库名称
jdbc.username=root
## 数据库密码
jdbc.password=root
# Druid
## 配置初始化大小、最小、最大
druid.initialSize=1
druid.minIdle=1
druid.maxActive=20
## 配置获取连接等待超时的时间
druid.maxWait=60000
## 配置间隔多久才进行一次检测，检测需要关闭的空闲连接
druid.timeBetweenEvictionRunsMillis=60000
## 配置一个连接在池中最小生存的时间
druid.minEvictableIdleTimeMillis=300000
## 验证连接有效与否的SQL，不同的数据配置不同
druid.validationQuery=SELECT 'x'
## 检测连接是否有效
druid.testWhileIdle=true
druid.testOnBorrow=true
druid.testOnReturn=false
## 打开PSCache，mysql可以配置为false
druid.poolPreparedStatements=false
druid.maxPoolPreparedStatementPerConnectionSize=20
## 这里配置提交方式
druid.defaultAutoCommit=true
## 合并多个DruidDataSource的监控数据
druid.useGlobalDataSourceStat=true
## 开启Druid的监控统计功能
druid.filters=stat,wall4.2、log4j2.xml
Log4j 2.0版本有了大幅的性能提升、新的插件系统，以及配置设置方面的很多改善。

</beans>6、SSM配置文件(resources目录下创建mybatis和mapper文件夹)
6.1、mybatis-config.xml （详细说明）- 位于mybatis文件夹
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 配置全局属性 -->
<settings>
<!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值 -->
<setting name="useGeneratedKeys" value="true" />
<!-- 使用列别名替换列名 默认:true -->
<setting name="useColumnLabel" value="true" />
<!-- 开启驼峰命名转换:Table{create_time} -> Entity{createTime} -->
<setting name="mapUnderscoreToCamelCase" value="true" />
</settings>
</configuration>7、创建简单测试程序
7.1、在WEB-INF下创建views文件夹，创建test.jsp方便测试
7.2、创建controller和相关文件夹，创建TestController类测试
package com.ray.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* @author Ray
* @date 2018/7/14 0014
*/
@Controller
public class TestController {
@RequestMapping("test")
public String test(){
return "test";
}
}
