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;

        at com.myproject.MyProject.main(MyProject.java:XX)

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。
