1、首先使用maven构建一个web项目，目录结构如下

 

2、配置pom.xml

  <!-- spring  -->       <dependency>           <groupId>org.springframework</groupId>           <artifactId>spring-context</artifactId>           <version>4.1.2.RELEASE</version>       </dependency>

3、创建所需的配置文件

ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>    <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"        updateCheck="false">        <!--            name:cache唯一标识             eternal：缓存是否永久有效             maxElementsInMemory：内存中最大缓存对象数            overflowToDisk(true,false)：缓存对象达到最大数后，将缓存写到硬盘中            diskPersistent：硬盘持久化            timeToIdleSeconds：缓存清除时间             timeToLiveSeconds：缓存存活时间            memoryStoreEvictionPolicy：缓存清空策略            1.FIFO：first in first out 先讲先出            2.LFU： Less Frequently Used 一直以来最少被使用的            3.LRU：Least Recently Used  最近最少使用的         -->        <defaultCache maxElementsInMemory="1000" eternal="false"            timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="false" />                            <cache name="infoCache" eternal="false" maxElementsInMemory="1000"            overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="3600"            timeToLiveSeconds="3600" memoryStoreEvictionPolicy="LFU" />    </ehcache>

hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?>  <!DOCTYPE hibernate-configuration PUBLIC          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"          "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">    <hibernate-configuration>      <session-factory>      </session-factory>  </hibernate-configuration>

log4j.properties

#此句为将等级为INFO的日志信息输出到stdout和logfile这两个目的地，stdout和logfile的定义在下面的代码，可以任#意起名。  #等级可分为OFF、FATAL、ERROR、WARN、INFO、DEBUG、ALL  #如果配置OFF则不打出任何信息，如果配置为INFO这样只显示INFO, WARN, ERROR的log信息，而DEBUG信息不会被显示，#具体讲解可参照第三部分定义配置文件中的logger。    log4j.rootLogger=INFO, stdout, logfile    log4j.appender.stdout=org.apache.log4j.ConsoleAppender  log4j.appender.stdout.Target=System.out  log4j.appender.stdout.layout=org.apache.log4j.PatternLayout  log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c:%L - %m%n    log4j.appender.logfile=org.apache.log4j.RollingFileAppender  log4j.appender.logfile.File=log/info.log  log4j.appender.logfile.MaxFileSize=10240KB    log4j.logger.com.wong=DEBUG  log4j.logger.org.springframework=INFO  log4j.logger.org.hibernate=ERROR    log4j.appender.logfile.MaxBackupIndex=3    log4j.appender.logfile.layout=org.apache.log4j.PatternLayout  log4j.appender.logfile.layout.ConversionPattern=%d %p [%c %L] - %m%n
