寫在前面：上一篇博客寫了spring cache和ehcache的基本介紹，個人建議先把這些最基本的知識了解了才能對今天主題有所感觸。不多說了，開干！
注：引入jar
<!-- 引入ehcache緩存 -->
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>2.8.3</version>
</dependency>
第一步：首先配置ehcache.xml
<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="ehcache.xsd"
updateCheck="true" monitoring="autodetect"
dynamicConfig="true">
<diskStore path="java.io.tmpdir"/>
<defaultCache
maxEntriesLocalHeap="10000"
eternal="false"
overflowToDisk="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
diskSpoolBufferSizeMB="30"
maxEntriesLocalDisk="10000000"
diskExpiryThreadIntervalSeconds="120"
memoryStoreEvictionPolicy="LRU">
<persistence strategy="localTempSwap"/>
</defaultCache>
<cache name="myCache"
maxEntriesLocalHeap="10000"
maxEntriesLocalDisk="1000"
eternal="false"
diskSpoolBufferSizeMB="30"
timeToIdleSeconds="300"
timeToLiveSeconds="600"
memoryStoreEvictionPolicy="LFU"
transactionalMode="off">
<persistence strategy="localTempSwap"/>
</cache>
</ehcache>
第二步：在spring.xml的配置文件中引入schema，
xmlns:aop="http://www.springframework.org/schema/aop"和http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.2.xsd
緩存的配置：
<!-- 啟用緩存注解功能，這個是必須的，否則注解不會生效，另外，該注解一定要聲明在spring主配置文件中才會生效 -->
<cache:annotation-driven cache-manager="ehcacheManager"/>
<!-- cacheManager工廠類，指定ehcache.xml的位置 -->
<bean id="ehcacheManagerFactory" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<property name="configLocation" value="classpath:ehcache.xml" />
</bean>
<!-- 聲明cacheManager -->
<bean id="ehcacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
<property name="cacheManager" ref="ehcacheManagerFactory" />
</bean>
OK!緩存的相關配置已經完成。下面開始編寫測試程序。這裡需要連接數據庫，我就不寫了。這裡為了方便就隨便找了之前寫過的model，這個model就是AOP注解實現日志管理的實體，為了偷懶就直接用了，希望你們不要誤解，沒有特殊意義的
第三步：編寫model，這裡需要注意，要實現緩存的實體必須要序列化 private static final long serialVersionUID = -6579533328390250520L; 關於序列化的生成這裡就不介紹了，大家可以百度看看。
package org.shop.entity;
import java.io.Serializable;
import java.util.Date;
public class SystemLog implements Serializable {
private static final long serialVersionUID = -6579533328390250520L;
private String id;
private String description;
private String method;
private Long logType;
private String requestIp;
private String exceptioncode;
private String exceptionDetail;
private String params;
private String createBy;
private Date createDate;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id == null ? null : id.trim();
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description == null ? null : description.trim();
}
public String getMethod() {
return method;
}
public void setMethod(String method) {
this.method = method == null ? null : method.trim();
}
public Long getLogType() {
return logType;
}
public void setLogType(Long logType) {
this.logType = logType;
}
public String getRequestIp() {
return requestIp;
}
public void setRequestIp(String requestIp) {
this.requestIp = requestIp == null ? null : requestIp.trim();
}
public String getExceptioncode() {
return exceptioncode;
}
public void setExceptioncode(String exceptioncode) {
this.exceptioncode = exceptioncode == null ? null : exceptioncode.trim();
}
public String getExceptionDetail() {
return exceptionDetail;
}
public void setExceptionDetail(String exceptionDetail) {
this.exceptionDetail = exceptionDetail == null ? null : exceptionDetail.trim();
}
public String getParams() {
return params;
}
public void setParams(String params) {
this.params = params == null ? null : params.trim();
}
public String getCreateBy() {
return createBy;
}
public void setCreateBy(String createBy) {
this.createBy = createBy == null ? null : createBy.trim();
}
public Date getCreateDate() {
return createDate;
}
public void setCreateDate(Date createDate) {
this.createDate = createDate;
}
}
第四步：編寫dao，service
package org.shop.dao;
import org.shop.entity.SystemLog;
public interface SystemLogMapper {
int deleteByPrimaryKey(String id);
int insert(SystemLog record);
int insertSelective(SystemLog record);
SystemLog selectByPrimaryKey(String id);
int updateByPrimaryKeySelective(SystemLog record);
int updateByPrimaryKey(SystemLog record);
int count();
}
public interface SystemLogService {
int deleteSystemLog(String id);
int insert(SystemLog record);
int insertTest(SystemLog record);
SystemLog findSystemLog(String id);
int updateSystemLog(SystemLog record);
int count();
}
