本文介绍如何配置EHCache缓存管理器并整合SLF4J与Log4j日志框架。通过示例展示了ehcache.xml配置文件的具体设置，包括缓存策略和磁盘存储路径等。同时，针对SLF4J与Log4j共存导致的日志绑定冲突问题给出了解决方案。

配置问题文件

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">
<diskStore path="java.io.tmpdir/ehcache"/>
<defaultCache
maxElementsInMemory="1000"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
overflowToDisk="false"/>

<cache name="menuCache"
maxElementsInMemory="1000"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
overflowToDisk="false"
memoryStoreEvictionPolicy="LRU"/>
</ehcache>

applicationContext.xml 只有关于ehcache的配置，其他配置没有贴出来

测试方法

@Cacheable(value="menuCache")
public String getkey(String k)
{
log.debug("进来了");
return "55985985555";
}

log4j.properties

#定义根日志级别和输出端(定义了两个输出端)
#log4j.rootLogger=DEBUG,CONSOLE,D,E
log4j.rootLogger=DEBUG,CONSOLE
#定义第一个输出端，输出到控制台
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d [%t] %-5p %c(%L) - %m%n
### 输出到日志文件 ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

### 保存异常信息到单独文件 ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = logs/error.log
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

#定义具体某个包下的日志输出级别
log4j.logger.org.springframework=ERROR

slf4j+log4j出现的问题

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [zip:D:/Oracle/Middleware/user_projects/domains/base_qumancheng/servers/AdminServer/tmp/_WL_user/_appsdir_ainmeweb_dir/e5r7ej/war/WEB-INF/lib/slf4j-jdk14-1.7.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [zip:D:/Oracle/Middleware/user_projects/domains/base_qumancheng/servers/AdminServer/tmp/_WL_user/_appsdir_ainmeweb_dir/e5r7ej/war/WEB-INF/lib/slf4j-log4j12-1.7.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.JDK14LoggerFactory]

错误提示，在两个包中存在相同的StaticLoggerBinder.class 删除一个class即可
