【WEB应用】SSM框架搭建
推荐看我新整理的【WEB应用】SSM框架搭建V2.0
1、设置本地仓库，apache-maven-3.6.3\conf\settings.xml
<localRepository>D:\淘宝\mavenDownload</localRepository>
2、eclipse整合maven
Windows-preferences-Maven-Installations-add apache-maven-3.6.3路径
Windows-preferences-Maven-UserSettings-Browse Browse apache-maven-3.6.3\conf\settings.xml路径
Windows-preferences-Maven-UserSettings-Reindex D:\淘宝\mavenDownload
3、创建maven项目
File-new-other-Maven-MavenProject
勾选Create a simple project(skip archetype selection) ，next
Group Id : com.xyc.taobao.ssm（包名）
Artifact Id : taobao_ssm
Packaging : war
4、项目右击—properties-Project Facts-Dynamic Web module 去勾，选3.1，Java 1.5变为1.8，应用。
Project Facts-Dynamic Web module 勾选，
Furthe configuration available Content directory: src/main/webapp OK
Web.xml
补齐</web-app>
5、pom.xml
https://mvnrepository.com/artifact/mysql/mysql-connector-java
查看依赖包的版本

6、web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</web-app>
7、src/main/resources下创建xml
springmvc.xml
spring.xml
mybatis-config.xml
8，springmvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- 扫描controller（controller层注入） -->
<context:component-scan base-package="com.xyc.taobao.ssm.controller"/>
<context:annotation-config/>
<mvc:default-servlet-handler/>

<!-- 对模型视图添加前后缀 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
9、spring.xml

jdbc.user=taobao
jdbc.password=123456
jdbc.pool.initialSize=1

log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
12、运行
window -> preferences –server -Runtime Environments-add
选择对应的Tomcat版本，勾选 Create a new local server点击 “next” , 设置被添加的tomcat 的 安装目录D:\淘宝\环境部署\apache-tomcat-9.0.37, JRE选择独立安装JDK中的JRE，点击 “Finnish” ，点击 “close and apply“。
Window -> show view -> Server
点击 面板中 “click this to create a new server”，选择正确的Server版本，点击“Finnish” 。
双击 tomcat 实例，打开实例配置界面，
Server Locations选择第二项 Use Tomcat installation
修改
Server Path ：D:\淘宝\环境部署\apache-tomcat-9.0.37
deploy path ：D:\淘宝\环境部署\apache-tomcat-9.0.37\webapps
Ctrl + s 保存配置
项目右击-run as – run on server 选择tomcat next完成
FAQ:
项目右键 maven- update project后，报错ContextLoaderListener]错误
项目右键properties-deployment assembly-add-java build path entries应用就可以
1，MAVEN通过配置，可以自动下载spring、springMVC、Mybatis包并安装部署
2，MAVEN需要单独下载
3，mysql需要单独下载，基本命令：
mysql -uroot -p
root 密码：123456
taobao 密码：123456
show databases;
use taobao;
show tables;
4，JDK需要单独下载
5，tomcat需要单独下载
