Log-ssm中日志文件的配置

首先在我们在pom文件中引入日志jar包

 
    <dependency>
      <groupId>ch.qos.logbackgroupId>
      <artifactId>logback-classicartifactId>
      <version>1.2.3version>
    dependency>

单独配置logback.xml日志文件

    <property name="log.maxHistory" value="30"/>

我们在访问此url路径，打印台会出现以下信息：

我们发现，上面的日志信息中，不仅有我们测试用例中日志信息，还有一些额外的日志信息，这些额外的日志信息是mybatis自己调用log打印的debug信息。

如何找到tomcat实例下的日志存储路径？

 
    <property name="log.filePath" value="${catalina.base}/logs/webapps"/>

我们在logback中定义日志的存储路径为tomcat根路径。如何找到tomcat根路径呢？
在我们启动tomcat实例后，在控制台找下面关键字 Dcatalina.base
其后面的url就是tomcat实例的根目录。

我们顺利找到了需要的日志文件，上面的文件夹保存的是以前日志的压缩包，下面的三个文档就是当面的运行日志。

此为我们的error的日志信息。

2020-02-06 13:28:15.759[http-nio-8080-exec-7]ERRORcom.web.superadmin.AreaController-test error!
