1.使用maven创建一个web项目
	2.配置相关jar包，注意版本
	<!-- 从阿里云仓库下载 -->
	<repositories>
		<repository>
			<id>public</id>
			<name>aliyun nexus</name>
			<url>http://maven.aliyun.com/nexus/content/groups/public/</url>

	</properties>

	3.创建spring配置文件，做redis基础配置，以及redis session配置
<?xml version="1.0" encoding="UTF-8"?>
<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"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

	<context:component-scan base-package="com.*"></context:component-scan>

	<bean id="jedisConnectionFactory"
		class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
		p:host-name="192.168.1.23" p:port="6379" />

	<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate"
		p:connection-factory-ref="jedisConnectionFactory">
	</bean>

	<bean id="redisHttpSessionConfiguration" class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
        <property name="maxInactiveIntervalInSeconds" value="1800"/>
    </bean>

</beans>

	4.在web.xml中增加springSession过滤器，要保证这个过滤器在所有过滤器的最前面
	<filter>
		<filter-name>springSessionRepositoryFilter</filter-name>
		<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>springSessionRepositoryFilter</filter-name>
		<url-pattern>/*</url-pattern>
		<dispatcher>REQUEST</dispatcher>
		<dispatcher>ERROR</dispatcher>
	</filter-mapping>

	5.配置web环境
	创建springmvc配置文件，等
<?xml version="1.0" encoding="UTF-8"?>
<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"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">
		
		
		<!-- ************************** SpringMvc 必要配置  begin  **************************-->
		
		<!-- 自动扫描 记得修改包的路径 -->
		<context:component-scan base-package="com"/>
		
		<!-- 视图解析器 记得关注前缀 -->
		<bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
			<property name="prefix" value="/WEB-INF/jsp/"/>
			<property name="suffix" value=".jsp"/>
		</bean>
		
		<!-- 静态资源访问  -->
		<mvc:default-servlet-handler/>
		<mvc:annotation-driven />
		
</beans>

在web.xml中增加配置
<!-- spring相关配置 -->
	<!-- 保证在tomcat启动时容器就可以被初始化 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- 初始化容器时需要读取配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<!-- spring配置文件的路径 -->
		<param-value>classpath*:spring-ioc.xml</param-value>
	</context-param>

	<!-- 内存清理 -->
	<listener>
		<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
	</listener>

	<servlet>
		<servlet-name>dispatcher</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

package com.controller;

import javax.servlet.http.HttpSession;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;


@Controller
public class TestController {
	/**
	 * 向session中保存数据
	 */
	@RequestMapping("/save")
	
	public String save(HttpSession session){
	session.setAttribute("str", "我是隔壁老王");
		return "test";
	}
	/**
	 * 从session中获取数据
	 */
	@RequestMapping("/get")
	public String get(HttpSession session){
		String  attribute = (String) session.getAttribute("str");
		System.out.println(attribute);
		return "test";
	}
}
  • 在虚拟机开启redis 和nginx tomcat
    • Linux的命令总结：
      • 连接redis不成功可能是防火墙：(当然在公司不可能采用如此极端的方式)systemctl stop firewalld.service
- 查看所有一个应用的pid: ps -ef |grep ngix
- 开启nginx:在nginx 的文件夹下进入到nginx 的sbin的目录下，开启nginx: ./nginx -t
- 关闭nginx:查找进程号 pid 并且用pid kill -9 pid
- 开启redis(相当于缓存存储数据)：redis-server /etc/redis/redis.conf
- 关闭redis : kill -9 进程号 pid
- 开启tomcat:进入到usr/local/tomcat/bin/start.h ---> ./start.h
- 开启tomcat的日志文件：usr/local/tomcat/logs/-----> tail -f catalina.out
- zookeeper的开启方式：进入到usr/local/zookeeper/bin  ----> ./zkServer.sh start
- 检验是否开启成功： netstat -ano|grep 2181 (任何应用的端口都可以查出来)
