SpringMVC web 项目 logback 使用

Spring 3.X + Dynamic Web Module 2.X

gradle

dependencies {
	// 使用 logback
	compile 'ch.qos.logback:logback-classic:1.2.3'
	compile 'org.logback-extensions:logback-ext-spring:0.1.1'
	compile 'org.slf4j:log4j-over-slf4j:1.7.25'
	compile 'org.slf4j:jcl-over-slf4j:1.7.1'
}

// ...

configurations.all {
    // 在全局配置中排除掉所有的 log4j
    exclude group: "org.slf4j", module: "slf4j-log4j12"
    exclude group: "log4j", module: "log4j"
}
// 或者
configurations {
    // 在全局配置中排除log4j和slf4j-log4j12依赖，使用 logback
    compile.exclude group: 'log4j', module: 'log4j'
    compile.exclude group: 'org.slf4j', module: 'slf4j-log4j12'
    // all*.exclude
}

web.xml 定义

        <param-name>logbackConfigLocation</param-name>
        <param-value>classpath:logback.xml</param-value>

相关配置参数可配置在application.properties

logback.log.home=${catalina.base}/logs/${APP_NAME}
logback.log.operation=${logback.log.home}/operation
logback.log.visit=${logback.log.home}/visit
logback.log.maxHistory=180
logback.log.maxFileSize=50MB

SpringBoot2 logback 配置可参考Spring Boot学习3——日志管理
