前言

将采用slf+log4j2方式进行打印日志，以下用两种方式，一种基于maven的springboot2，一种jdk6,普通jar包的springmvc

基于maven的springboot

第一步、由于前阵子java8可对应的log4j漏洞问题，公司要求log4j升级到2.17.1，因此需要把springboot自带的log4j进行排除引入高版本。

<properties>
<log4j2.version>2.17.1</log4j2.version>
</properties>

				<exclusion>

				</exclusion>
			</exclusions>
		</dependency>

第二步 log4j.xml

以下patternLayout做了对邮件、手机号、身份证号敏感数据转码**

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="ERROR">
  <Appenders>
    <Console name="console" target="SYSTEM_OUT">
      <PatternLayout>
<!--        <pattern>%d{ISO8601}|%level|%thread|%c{1.}|%L|%msg%n</pattern>-->
        <pattern><![CDATA[%d{ISO8601}|%level|%thread|%c|%L|%replace{%replace{%replace{%msg}{(^|\D)([\d]{12})(\d{3}|\d{6}|\d{5}(\d|X|x))(\D|$)}{$1$2******$5}}{(^|\D)(1([358][0-9]|4[579]|66|7[0135678]|9[89])([0-9]{4})([0-9]{4}))(\D|$)}{$11$3****$5$6}}{(([A-Za-z0-9-_.]{1,3})([A-Za-z0-9-_.]*)(@[a-zA-Z0-9-_.]+(\.[a-zA-Z-_.]+)+))}{$2***$4}%n]]></pattern>
      </PatternLayout>
    </Console>
    <RollingFile name="file" filePattern="/qhapp/applogs/imeeting/imeeting_business_%d{yyyyMMdd}_%i.log" immediateFlush="true">
      <PatternLayout>
        <pattern>%d{ISO8601}|%level|%thread|%c{1.}|%L|%msg%n</pattern>
      </PatternLayout>
      <Policies>
        <TimeBasedTriggeringPolicy modulate="true" interval="1"/>
        <SizeBasedTriggeringPolicy size="10 MB"/>
      </Policies>
    </RollingFile>
  </Appenders>
  <Loggers>
    <Root level="INFO">
      <AppenderRef ref="console"/>
    </Root>
    <Logger name="org.mybatis" level="INFO" additivity="false">
      <AppenderRef ref="console"/>
    </Logger>
    <Logger name="org.springframework" level="INFO" additivity="false">
      <AppenderRef ref="console"/>
    </Logger>
    <Logger name="com.company.booster" level="INFO" additivity="false">
      <AppenderRef ref="console"/>
    </Logger>
  </Loggers>
</Configuration>

第三步 输出sql的mapper接口包，写在*.properties，放置在resource下

#debug log 自己项目的包，写dao接口的位置
logging.level.com.company.pm.mapper=debug

重新启动即可，sql日志就会出来，如果想自己logger出来，用slf即可

Logger logger = LoggerFactory.getLogger(getClass());
logger.debug("6867868@qq.com");

第二种 jdk6,普通jar包的springmvc

spring3 + mybatis3

jdk6建议log4j版本为2.3.2(官方因漏洞推荐)，引入以下个jar包

log4j-slf4j-impl-2.3.2.jar、log4j-core-2.3.2.jar、log4j-api-2.3.2.jar、slf-api-1.7.25.jar、log4j-slf-impl-2.3.2.jar

由于不是maven项目，只是普通的mvc结构，因此我在src下建了两个文件log4j2.xml（有些是resource，这个项目前期没有这个，反正最后打包后在class下面就是了）

log4j2.xml，不知道，为啥在jdk6以及版本log4j2.3.2里面为何pattern不能写多个replace，因此我只排除了邮箱敏感信息

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="ERROR">
  <Appenders>
    <Console name="console" target="SYSTEM_OUT">
      <PatternLayout>

        <pattern><![CDATA[%d{ISO8601}|%level|%thread|%c|%L|%replace{%msg}{(([A-Za-z0-9-_.]{1,3})([A-Za-z0-9-_.]*)(@[a-zA-Z0-9-_.]+(\.[a-zA-Z-_.]+)+))}{$2***$4}%n]]></pattern>
<!--        <pattern><![CDATA[%d{ISO8601}|%level|%thread|%c|%L|%replace{%replace{%replace{%msg}{(^|\D)([\d]{12})(\d{3}|\d{6}|\d{5}(\d|X|x))(\D|$)}{$1$2******$5}}{(^|\D)(1([358][0-9]|4[579]|66|7[0135678]|9[89])([0-9]{4})([0-9]{4}))(\D|$)}{$11$3****$5$6}}{(([A-Za-z0-9-_.]{1,3})([A-Za-z0-9-_.]*)(@[a-zA-Z0-9-_.]+(\.[a-zA-Z-_.]+)+))}{$2***$4}%n]]></pattern>-->

      </PatternLayout>
    </Console>
  </Appenders>
  <Loggers>
    <Root level="INFO">
      <AppenderRef ref="console"/>
    </Root>
    <Logger name="com.xxx自己的包.dao" level="DEBUG" additivity="false">
      <AppenderRef ref="console"/>
    </Logger>
    <Logger name="org.mybatis" level="DEBUG" additivity="false">
      <AppenderRef ref="console"/>
    </Logger>
    <Logger name="org.apache.ibatis" level="DEBUG" additivity="false">
      <AppenderRef ref="console"/>
    </Logger>
    <Logger name="org.springframework" level="INFO" additivity="false">
      <AppenderRef ref="console"/>
    </Logger>
    <Logger name="com.xxx自己的包" level="INFO" additivity="false">
      <AppenderRef ref="console"/>
    </Logger>
  </Loggers>
</Configuration>

mybatis-config.xml

<!-- 配置SqlSessionFactoryBean -->
	<bean class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="configLocation" value="classpath:configuration/mybatis-config.xml" />
		.....
	</bean>

application-context.cml

<!-- 配置SqlSessionFactoryBean -->
	<bean class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="configLocation" value="classpath:configuration/mybatis-config.xml" />
		.....
	</bean>

这里jdk6 slf+ log4j2有个坑点，我不知道为何log4j.properties与log4j.xml不能同时存在

测试类

Logger logger = LoggerFactory.getLogger(getClass());
		logger.debug("6867868@qq.com");
