springMVC+spring+maven+mybatis第一篇配置

项目描述
该项目采用springMVC+spring+maven+mybatis+redis搭建的一个小demo工程，并且实现了增删改查操作，系统需要登录，登录后会记录session，session采用redis的记录的方式，方便搭建加群后session实现共享，自定义一个拦截器，当session失效或者非法访问界面都会跳转到登录界面。
项目结构

spring的配置文件分为web层、service层、dao层等，统一为spring-开头，方便在web.xml中进行加载
2.1 spring-web.xml

改文件主要配置redis的连接信息，使用redisTemplate来操作redis缓存，并且声明session存储在session中，这样在集群环境中，session可以共享
<?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" 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-4.0.xsd"> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxIdle" value="1" /> <property name="maxTotal" value="5" /> <property name="blockWhenExhausted" value="true" /> <property name="maxWaitMillis" value="30000" /> <property name="testOnBorrow" value="true" /> </bean> <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"> <property name="hostName" value="${redis.hostname}" /> <property name="port" value="${redis.port}" /> <property name="poolConfig" ref="jedisPoolConfig" /> <property name="usePool" value="true" /> </bean> <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"> <property name="connectionFactory" ref="jedisConnectionFactory" /> <property name="keySerializer"> <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" /> </property> <property name="valueSerializer"> <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" /> </property> <property name="hashKeySerializer"> <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" /> </property> <property name="hashValueSerializer"> <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" /> </property> </bean> <!-- 将session放入redis --> <context:annotation-config/> <bean id="redisHttpSessionConfiguration" class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration"> <property name="maxInactiveIntervalInSeconds" value="1800" /> </bean></beans>3. properties配置文件
该配置文件在props文件夹下，主要配置数据库及redis链接信息，dev.properties配置信息如下
