了解如何使用**多个文件追加器**在[Spring 引导][Spring]应用程序中创建**多个日志文件**。了解如何使用翻转策略、归档等配置所有文件追加器，wiih[log4j2][]和[日志][Link 1]配置。

### **1. 带登录的多个日志文件** ###

以下文件包含 5 个记录器。我们可以根据需要创建更多的记录器。`logback.xml`

*  `console`– 将输出记录到控制台。包括所有日志语句。
 *  `applicationLog`– 将输出记录到。包括包的应用程序日志。`application.log``debug``com.howtodoinjava.demo`
 *  `aopLog`– 将输出记录到。在包中包含应用程序日志。`application-aop.log``info``com.howtodoinjava.demo.aop`
 *  `springLog`– Createand 包含 spring 框架生成的所有错误日志。`spring-framework.log`
 *  `hibernateLog`– 创建并包含休眠生成的所有错误日志。`database.log`

> 放置给定**资源**文件夹。`logback.xml`
