不知不觉在SSM相关的开发时间比较长了，但是都是基于平台的开发，慢慢地自己也被平台化了，跟面试其他人一样，对底层架构的了解开始模糊，关注业务开发，下面整合下如何搭建基础的SSM+redis开发框架。
首先是新建一个MAVEN的项目，代码内容可以见附件，下面介绍下主要的配置段落
web.xml中,配置spring，mybatis 和 springmvc的配置
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml;classpath:spring-mybatis.xml</param-value>
</context-param>
<servlet>
<description>spring mvc servlet</description>
<servlet-name>rest</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>
之后进行sping的配置比较简单 主要是配置扫描的包路径
<context:component-scan base-package="com.cn" />
springmvc中主要配置包的路径和界面解析
<!-- 自动扫描controller包下的所有类，如果@Controller注入为bean -->
<context:component-scan base-package="com.cn" />
<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
之后开始配置mybatis.xml和 redis，mybatis需要打开缓存设置，
<?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mybatis的缓存，延迟加载等相关属性 -->
<settings>
<!-- 是否开启全局缓存 -->
<setting name="cacheEnabled" value="true"/>
<!-- 查询时，关闭关联对象即时加载以提高性能 -->
<setting name="lazyLoadingEnabled" value="false"/>
<!-- 对于未知的SQL查询，允许返回不同的结果集以达到通用的效果 -->
<setting name="multipleResultSetsEnabled" value="true"/>
<!-- 设置关联对象加载的形态，此处为按需加载字段(加载字段由SQL指 定)，不会加载关联表的所有字段，以提高性能 -->
<setting name="aggressiveLazyLoading" value="true"/>
<setting name="logImpl" value="LOG4J"/>
</settings>
</configuration>
之后引入jdbc.properties 和 redis.properties，进行配置
<!-- 引入配置文件 -->
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
<value>classpath:redis.properties</value>
</list>
</property>
</bean>
之后进行mybatis和redis的配置信息了
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
<!-- 初始化连接大小 -->
<property name="initialSize" value="${initialSize}"></property>
<!-- 连接池最大数量 -->
<property name="maxActive" value="${maxActive}"></property>
<!-- 连接池最大空闲 -->
<property name="maxIdle" value="${maxIdle}"></property>
<!-- 连接池最小空闲 -->
<property name="minIdle" value="${minIdle}"></property>
<!-- 获取连接最大等待时间 -->
<property name="maxWait" value="${maxWait}"></property>
</bean>
<!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="configLocation" value="classpath:mybatis-configure.xml"/>
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:com/cn/*/*.xml"></property>
</bean>
<!-- DAO接口所在包名，Spring会自动查找其下的类 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.cn.*" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
<!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 配置redis 单机版 -->
<!-- redis数据源 -->
<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
<!-- 最大空闲数 -->
<property name="maxIdle" value="${redis.maxIdle}" />
<!-- 最大空闲数 -->
<property name="maxTotal" value="${redis.maxActive}" />
<!-- 最大等待时间 -->
<property name="maxWaitMillis" value="${redis.maxWait}" />
<!-- 返回连接时，检测连接是否成功 -->
<property name="testOnBorrow" value="${redis.testOnBorrow}" />
</bean>
<!-- Spring-redis连接池管理工厂 -->
<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<!-- IP地址 -->
<property name="hostName" value="${redis.host}" />
<!-- 端口号 -->
<property name="port" value="${redis.port}" />
<!-- 超时时间 -->
<property name="timeout" value="${redis.timeout}" />
<property name="poolConfig" ref="poolConfig" />
</bean>
<!-- redis 集群 -->
<!-- <bean id="redisClient" class="redis.clients.jedis.JedisCluster">
<constructor-arg name="nodes">
<bean class="redis.clients.jedis.HostAndPort">
<constructor-arg name="host" value="192.168.10.105"></constructor-arg>
<constructor-arg name="port" value="7002"></constructor-arg>
</bean>
<bean class="redis.clients.jedis.HostAndPort">
<constructor-arg name="host" value="192.168.10.77"></constructor-arg>
<constructor-arg name="port" value="7002"></constructor-arg>
</bean>
</constructor-arg>
</bean> -->
<!-- redis模板类，提供了对缓存的增删改查 -->
<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>
</bean>
<!-- StrRedisTemplate -->
<bean id="strRedisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<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.StringRedisSerializer" />
</property>
<property name="hashKeySerializer">
<bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />
</property>
</bean>
<!-- 使用中间类解决RedisCache.jedisConnectionFactory的静态注入，从而使MyBatis实现第三方缓存 -->
<bean id="redisCacheTransfer" class="com.cn.utils.RedisCacheTransfer">
<property name="jedisConnectionFactory" ref="jedisConnectionFactory"/>
</bean>
<!-- //End 单机版Redis集成 -->
<!-- Redis缓存管理对象 -->
<bean id="cacheManager" class="org.springframework.data.redis.cache.RedisCacheManager">
<constructor-arg index="0" ref="redisTemplate" />
</bean>
<!-- 开启Spring缓存 -->
<cache:annotation-driven cache-manager="cacheManager"/>
之后写上controller和 service 和dao 层，进行程序的运行，打开数据库，redis服务器，进行数据访问测试
