如何通过 log4j2
以及我拥有的其他依赖项(Hibernate、Netty、Mina 等)正确地生成 Spring 日志?
我尝试了许多不同的细化和依赖性组合。但我要么可以让 Spring 记录日志,要么只记录 Spring。
在所有依赖项都正确记录(但 Spring)的情况下,我收到以下错误:
java.lang.NoSuchMethodError: org.apache.logging.log4j.core.config.ConfigurationFactory.getConfiguration(Lorg/apache/logging/log4j/core/config/ConfigurationSource;)Lorg/apache/logging/log4j/core/config/Configuration;

这是我的build.gradle
依赖
dependencies {
// FIX engine
compile 'org.quickfixj:quickfixj-all:1.6.2'
compile 'org.apache.mina:mina-core:2.0.16'
// Web API
compile ('org.springframework.boot:spring-boot-starter-web:1.4.1.RELEASE') {
// Remove default Spring loggers (where logback takes precedence)
exclude module: 'spring-boot-starter-logging'
}
// Logging
compile 'org.apache.logging.log4j:log4j-api:2.7'
compile 'org.apache.logging.log4j:log4j-core:2.7'
compile 'commons-logging:commons-logging:1.2' // for Spring logging
compile 'org.apache.logging.log4j:log4j-web:2.7' // for Spring logging
compile 'org.apache.logging.log4j:log4j-slf4j-impl:2.7' // for Hibernate logging
// ORM and Database Driver
compile 'org.hibernate:hibernate-core:5.2.4.Final'
compile 'org.postgresql:postgresql:9.4.1209'
// Key-value store
compile 'biz.paluch.redis:lettuce:4.1.2.Final'
// Testing
// The Groovy language
compile 'org.codehaus.groovy:groovy-all:2.4.6'
// Spock testing framework
testCompile 'org.spockframework:spock-core:1.0-groovy-2.4'
}
然后,摆脱我的日志记录依赖并添加下面的依赖:
compile 'org.springframework.boot:spring-boot-starter-log4j2:1.4.1.RELEASE'
Spring 日志记录会工作,但其他 deps 日志记录不会。
这是main
方法(没什么特别的)
public static void main(String[] args) {
// Fine tune a few logging settings so they don't log with TRACE or DEBUG levels.
Configurator.setLevel("org.hibernate", Level.ERROR);
Configurator.setLevel("org.jboss", Level.ERROR);
Configurator.setLevel("org.apache.mina", Level.ERROR);
Configurator.setLevel("io.netty", Level.ERROR);
Configurator.setLevel("quickfix.mina", Level.WARN);
Configurator.setLevel("com.lambdaworks", Level.WARN);
// ...
logger.info("FIX Controller started. Loading the API.");
SpringApplication.run(MyProject.class, args);
}
那么,我怎样才能让 Spring 通过 log4j2
以及我拥有的其他依赖项正确记录日志?
最佳答案
Spring Boot 1.4.1 内置并支持 Log4J 2.6,但您正在尝试使用 2.7。不幸的是,这不起作用,因为在 this commit 中对 2.7 中的 API 进行了重大更改。 .这就是您看到的 NoSuchMethodError
的原因。
回到 Log4J2 2.6.2 应该可以解决这个问题。或者,您可以升级到使用 Log4J 2.7 的 Spring Boot 1.5。
