在SpringBoot中禁用登录

Question

似乎Springboot自动配置自己来使用Tomcat的Logback。我想禁用它，并使用我在类路径中提供的一个。

LoggerFactory不是LoggerContext，但Logback位于类路径上。删除Logback或类[org.slf4j.impl.SimpleLoggerFactory]的竞争实现（类org.slf4j.impl.SimpleLoggerFactory)对象必须是类ch.qos.Logback.classic.LoggerContext的实例

Answer 1

使用Gradle和Lombok，下面是我使用最新的Spring Boot（此时为2.4.1)时使用的最简单的Log4j2配置：

configurations {
    compileOnly { extendsFrom annotationProcessor }
    compile.exclude module: 'spring-boot-starter-logging'
}


dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-security' 
    implementation 'org.springframework.boot:spring-boot-starter-web-services'
    implementation 'org.springframework.boot:spring-boot-starter-log4j2'

    compileOnly 'org.projectlombok:lombok'

    // (*** other dependencies ***)

    annotationProcessor 'org.projectlombok:lombok'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'org.springframework.security:spring-security-test'
}

我注意到，如果将spring-bbot-starter-log4j2作为compileonly依赖项而不是作为实现包含，将会出现错误。

只要用@log4j2（或@slf4j)注释类，lombok就会提供一个log变量，您可以用来记录日志。

像往常一样，在/src/main/resources文件夹中提供log4j2.xml配置文件。
