maven + springmvc + mybatis + ehcache 搭建

搭建的过程主要是配置文件的编写，下面是所有需要的配置文件。

maven配置文件pom.xml

spring配置文件一共有3个，spring-mvc.xml、spring-mybatis.xml、spring-ehcache.xml

spring-mvc.xml

数据源配置文件 jdbc.properties

jdbc.url=jdbc:mysql://localhost:3306/myuser?useUnicode=true&characterEncoding=UTF-8jdbc.username=rootjdbc.password=123456

 

mybatis的配置文件一共有2个，mybatis-config.xml、user-mapper.xml

mybatis-config.xml

<?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> <typeAliases>       <typeAlias type="com.user.bean.User" alias="User" />    </typeAliases> <mappers>           <mapper resource="com/user/bean/user-mapper.xml" />   <!-- mapper对应的xml配置文件 -->    </mappers></configuration>

user-mapper.xml 在src目录下，与javabean在同一个目录

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.user.dao.UserDao"><cache type="org.mybatis.caches.ehcache.EhcacheCache"/><select id="selectUser" parameterType="string" resultType="User">SELECT * from myuser where  id = #{id}</select></mapper>

ehcache的配置文件ehcache.xml

ehcache.xml 在src目录下

<?xml version="1.0" encoding="UTF-8"?><ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="false"monitoring="autodetect" dynamicConfig="true"><diskStore path="java.io.tmpdir" /><!-- name：Cache的唯一标识 maxElementsInMemory：内存中最大缓存对象数 maxElementsOnDisk：磁盘中最大缓存对象数，若是0表示无穷大 eternal：Element是否永久有效，一但设置了，timeout将不起作用 overflowToDisk：配置此属性，当内存中Element数量达到maxElementsInMemory时，Ehcache将会Element写到磁盘中 timeToIdleSeconds：设置Element在失效前的允许闲置时间。仅当element不是永久有效时使用，可选属性，默认值是0，也就是可闲置时间无穷大 timeToLiveSeconds：设置Element在失效前允许存活时间。最大时间介于创建时间和失效时间之间。仅当element不是永久有效时使用，默认是0.，也就是element存活时间无穷大 diskPersistent：是否缓存虚拟机重启期数据 diskExpiryThreadIntervalSeconds：磁盘失效线程运行时间间隔，默认是120秒 diskSpoolBufferSizeMB：这个参数设置DiskStore（磁盘缓存）的缓存区大小。默认是30MB。每个Cache都应该有自己的一个缓冲区 memoryStoreEvictionPolicy：当达到maxElementsInMemory限制时，Ehcache将会根据指定的策略去清理内存。默认策略是LRU（最近最少使用）。你可以设置为FIFO（先进先出）或是LFU（较少使用） --><defaultCache maxElementsInMemory="10000" eternal="false"timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true"maxElementsOnDisk="10000000" diskPersistent="false"diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU" /><cache name="userCache" maxElementsInMemory="10000"maxElementsOnDisk="1000" eternal="false" overflowToDisk="true"diskSpoolBufferSizeMB="20" timeToIdleSeconds="300" timeToLiveSeconds="600"memoryStoreEvictionPolicy="LFU" /></ehcache>

至此，所有的配置文件已完成。
