spring从入门到精通精简笔记

}

} ApplicationContext actx = new FileSystemXmlApplicationContext( \); Log log = (Log) actx.getBean(\); log.log(\); 5. Spring的AOP

AOP基本思想

从一个输出日志的实例分析java的代理机制

建立java文件，用来模拟实际业务中的考勤审核的业务逻辑。

TimeBook.java package test.java; import org.apache.log4j.Level; import org.apache.log4j.Logger; publicclassTimeBook { }

TestHelloWord.java package test.java; // 审核数据的相关程序 publicvoid doAuditing(String name) { } logger.log(Level.INFO, name + \开始审核数据...\); logger.log(Level.INFO, name + \审核结束！\); private Logger logger = Logger.getLogger(this.getClass().getName()); publicclass TestHelloWord { } publicstaticvoid main(String[] args) { } TimeBook timeBook = new TimeBook(); timeBook.doAuditing(\张三\); 其他：

考入log4j-1.2.16.jar 修改web.xml文件

Web.xml

log4jConfigLocation /WEB-INF/log4j.properties log4jRefreshInterval 60000 org.springframework.web.util.Log4jConfigListener< org.springframework.web.context.ContextLoaderList index.jsp /listener-class> ener 配置log4j.properties放到src目录下。 Log4j.properties
