java - 如何解决 Java 和 Spring Boot 中的 slf4j logback 类路径错误？

Question

所以我目前正在使用 Twilio 发送和接收短信。我使用 Spring Boot 作为应用程序框架，使用 Gradle 作为构建工具，使用 VSCode 作为 IDE。

执行 bootRun 时它构建成功，但是我的本地主机服务器未启动并导致 DEBUG CONSOLE 中出现以下异常。

Below, I've put some parts of the Debug Console.

多重绑定(bind)

> Task :bootRun
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/james/.gradle/caches/modules-2/files-2.1/org.slf4j/slf4j-simple/1.7.21/be4b3c560a37e69b6c58278116740db28832232c/slf4j-simple-1.7.21.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/C:/Users/james/.gradle/caches/modules-2/files-2.1/ch.qos.logback/logback-classic/1.2.3/7c4f3c474fb2c041d8028740440937705ebb473a/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.SimpleLoggerFactory]

Caused by: java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.SimpleLoggerFactory loaded from file:/C:/Users/james/.gradle/caches/modules-2/files-2.1/org.slf4j/slf4j-simple/1.7.21/be4b3c560a37e69b6c58278116740db28832232c/slf4j-simple-1.7.21.jar).

Here are the implementation statements in my build.gradle file that are relevant to what I'm doing

implementation 'org.slf4j:slf4j-simple:1.7.21'
implementation 'com.sparkjava:spark-core:2.7.1'
implementation 'com.twilio.sdk:twilio:7.17.+'

Here are a few things that I have tried to solve the problem:

我尝试将另一个 StackOverflow 问题中的以下内容放入我的 gradle 文件中

configurations.all {
    exclude group: 'org.springframework.boot', module: 'spring-boot-starter-tomcat'
    exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
    exclude group: 'org.springframework.boot', module: 'logback-classic'
    exclude group: "org.slf4j"
}

此时运行 bootRun 会出现构建错误，并提示这些包不存在

我还尝试阅读DEBUG CONSOLE中的URL:http://www.slf4j.org/codes.html#multiple_bindings我没有找到任何对 Gradle 有用的东西，因为解决方案仅适用于 Maven。

此时我不知道还能做什么。

有什么想法吗？提前致谢。

Answer 1

Spring Boot 本身依赖 SLF4J 和 Logback 作为其实现。您需要从配置中删除实现“org.slf4j:slf4j-simple:1.7.21”。
