springmvc+logback项目的日志搭建

一、重写HTMLLayout

两个自定义类：LzhHTMLLayoutBase和LzhHTMLLayout

LzhHTMLLayoutBase代码如下：

package top.liaozhenghan.logback.study.layout;

三、查看日志的jsp页面


用了三个页面：登录页面loglogin.jsp，日志级别选择页面logselect.jsp，日志显示页面log.jsp

        model.addAttribute("date", date);
        model.addAttribute("level", level);
        return "logs/log";
    }
}




注：logback.xml在tomcat环境下的日志目录可改为：


<property name="LOG_PATH" value="${catalina.base}/logs" />


在java代码中获取文件目录改为：


String catalina_base = System.getProperty("catalina.base");
String filepath = catalina_base + "/logs/study/";

                springmvc+logback项目日志配置
			

		

		

									

				最近在做项目的时候用到logback作为项目日志,而抛弃了log4j.具体为什么用logback,我总结了以下几点: 1.log4j和logback的创作者是同一个人,logback是log4j的升级版,是对log4j核心的一个封装. 2.性能提升,在某些特定场景上执行速度提升10倍以上,同时初始化内存更小 3.扩展文档,丰富的并且详细的文档和不断的更新,可在官网上查看 4.Filters(过滤器),过滤器的使用又是logback的一大特色,在使用log4j的时候,当我们遇到问题时,我们需要降低

                解决：springmvc maven 项目搭建完后没有src目录
			

		

		

									

				前言:在搭建springmvc maven项目中遇到的问题做总结,比如搭建后没有src,同时这里也解决了搭建后maven导入很慢的问题. 问题: 1.发现创建出来的maven项目没有src文件 ,而且maven导入很慢 解决办法: 在新建项目的这个时候(如下图),点击加号,在name的输入框中填写archetypeCatalog,在value的输入框中填写internal,点击确定: 然后在所选择maven配置文件setting.xml里面加入以下代码,保存后回到 IDEA. <mirror>
