最近在自己搭建项目的时候，遇到logback选的问题，现在记录如下
在框架中使用logback日志框架，关于logback和log4j日志框架的选择，这里就不多说了网上百度一大堆，总之一句话 logback要比log4j效率高，性能好，配置灵活。
1.首先在maven中增加依赖
<dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>${logback.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> <version>${jcl-over.version}</version> </dependency>
定义各自版本
<logback.version>1.1.11</logback.version> <jcl-over.version>1.7.12</jcl-over.version>
因为采用的是maven聚合项目，所以这里 parent项目和common项目都需要加上，但是只需要给parent项目添加版本管理就行了
2.web.xml配置
<!--加载logback.xml配置文件--> <context-param> <param-name>logbackConfigLocation</param-name> <param-value>classpath:properties/logback.xml</param-value> </context-param> <listener> <listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class> </listener>
3.编写logback.xml
在线工具，可以将log4j的properties文件直接转换成logback的xml文件，地址如下：

logback的详细用法及其xml文件的相关语法，可参见它的用户向导，地址如下：

具体配置可以如下：（转自http://www.mkyong.com/logging/logback-xml-example/）更加具体的配置可以参考 文档 https://logback.qos.ch/manual/configuration.html

启动项目，效果如下：
在百度资料的时候发现 控制台还可以给不同的日志级别有不同的颜色，好吧，原谅我的无知。插件名：grep-console
测试结果如下：
