2019-10-31 1543 星期四 enAn 说明
1. 重写的 Log4jFile extends RollingFileAppender 2. Log4jFile.java 中的格式化类型与log4j.properties中的输出的文件目录一致 log4j.appender.logFile.File=${log.home.dir}/yyyy/MM/dd/web.log 3. 指向自己重写的类 log4j.appender.logFile=com.ecommerce.platform.common.log.Log4jFile 4. 另外log4j.properties中 log4j.rootLogger的变量logFile，必需与log4j.appender.logFile=com.ecommerce.platform.common.log.Log4jFile保持一致，不然不会输出日志 5.监听器，把变量设置到环境中 [设置到系统属性集 ]java.util.Properties System.out.println(className + "[设置到系统属性集 ]"); props.setProperty(InitConstant.DUBBO_REGISTRY_APPLICATION, dubbo_registry_application);//dubbo注册的应用名字 props.setProperty(InitConstant.DUBBO_REGISTRY_ADDRESS,dubbo_registry_address);//dubbo:注册地址 props.setProperty(InitConstant.DUBBO_CATALINA_HOME, dubbo_catalina_home);//dubbo缓存文件位置 props.setProperty(InitConstant.LOG_HOME_DIR, log_dir);//log日志文件位置**
log4j.properties和spring-mvc.xml，取监听器中设置的值
**
log4j.properties 设置值 log4j.appender.logFile.File=${log.home.dir}/yyyy/MM/dd/web.log spring-mvc.xml 设置值 <!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 --> <dubbo:application name="#{systemProperties['dubbo.registry.application']}" /> <!-- 使用zookeeper注册中心暴露服务地址 --> <dubbo:registry protocol="zookeeper" address="#{systemProperties['dubbo.registry.address']}" file="#{systemProperties['dubbo.catalina.home']}"/>log4j.properties配置文件内容
