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

这里写图片描述

2. spring配置文件

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

        <!-- 当设置多个拦截器时，先按顺序调用preHandle方法，然后逆序调用每个拦截器的postHandle和afterCompletion方法 -->
    </mvc:interceptors>
</beans>

2.2 spring-service.xml

<?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:context="http://www.springframework.org/schema/context"

        <property name="staticVersion" value="${static.version}" />
    </bean>

</beans>

2.3 spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </bean>

    <!-- 通过annotation（@Transactional）来使用spring提供的transactionManager -->
    <tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

2.4 spring-redis.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

mysql.driver=com.mysql.jdbc.Driver
mysql.url=jdbc:mysql://192.168.145.44:3306/cdt_dev
mysql.username=root
mysql.password=mysqlpwd
jdbc.maxPoolSize=1000
jdbc.maxIdleTime=1000
website.url=http://localhost:7081/bookstore
static.version=2017041200001

#redis config
redis.pool.maxActive=100
redis.pool.maxIdle=20
redis.pool.maxWait=1000
redis.pool.testOnBorrow=true
redis.hostname=192.168.158.132
redis.port=6379
redis.password=

4. web.xml

    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
