冲突的模块。 LoggerFactory 不是 Logback LoggerContext 但 Logback 在类路径上答案

【问题标题】：Conflicting modules. LoggerFactory is not a Logback LoggerContext but Logback is on the classpath冲突的模块。 LoggerFactory 不是 Logback LoggerContext 但 Logback 在类路径上
【发布时间】：2017-11-09 10:06:54
【问题描述】：

当我尝试运行我的项目时，我在标题中发现了错误。我已经阅读了有关此错误的其他线程，并找到了一个解决该错误的解决方案，但杀死了我所有的日志记录。

<exclusions>
    <exclusion>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-logging</artifactId>
    </exclusion>
</exclusions>

和

<exclusions>
    <exclusion>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
    </exclusion>
</exclusions>

两者都可以消除我的错误并终止我的日志记录。我宁愿能够保留我的 Spring-Boot 日志记录并解决此问题，但无法找到解决方案。有没有办法可以保留当前的日志记录并解决此依赖问题？追踪违规模块的最佳方法是什么？

完整的错误是：

线程“主”java.lang.IllegalArgumentException 中的异常： LoggerFactory 不是 Logback LoggerContext 但 Logback 在类路径。删除 Logback 或竞争实现（类 org.slf4j.impl.Log4jLoggerFactory 加载自文件：/C:/Users/me/.m2/repository/org/slf4j/slf4j-log4j12/1.6.4/slf4j-log4j12-1.6.4.jar）。如果您使用的是 WebLogic，则需要将“org.slf4j”添加到 WEB-INF/weblogic.xml 中的首选应用程序包： org.slf4j.impl.Log4jLoggerFactory

【问题讨论】：

你应该显示整个 pom，因为 Logback 在运行时仍然存在。
@davidxxx 添加了 pom
我也有类似的情况，但我使用的是过时的 10.3.6 版本的 WebLogic。我想我会发表评论，看看你是否已经想通了

标签： java spring spring-boot marklogic

【解决方案1】：

Spring Boot 因为 web starter 自动配置了 Log Back 库。您应该排除 spring-boot-starter-logging 来解决问题。

要排除maven项目中默认的LogBack配置，

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>

This 涵盖了 Gradle 和 Maven 项目的所有可能解决方案。

【解决方案2】：

在 Wildfly 23 中部署 Spring Boot 作为战争时，我遇到了同样的问题

所以我通过按以下顺序添加依赖项解决了这个问题。

 <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-log4j2</artifactId>
    </dependency>

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
