Kotlin/Corda/SpringBoot 应用程序导致 SLF4J StackOverflowError

Question

我不完全确定为什么它停止工作。我的项目几周前还在工作，但我刚刚尝试再次运行它，但我只是收到有关日志记录的 StackOverflowError

我正在运行的应用程序没有导致此问题，因为我已将 main 方法替换为空的方法：

class Application {
    companion object {
        @JvmStatic
        fun main(vararg args: String) {
            println("Hello, world.");
        }
    }
}

在控制台中出现以下错误（我已经删除了大部分，因为它只是导致 StackOverflowError 的重复）：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/user/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/log4j-slf4j-impl/2.11.2/4d44e4edc4a7fb39f09b95b09f560a15976fa1ba/log4j-slf4j-impl-2.11.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]

这些是我的 gradle 依赖项：

dependencies {
    // Main
    implementation "$kotlin_group:kotlin-stdlib-jdk8:$kotlin_version"
    implementation "$corda_group:corda-core:$corda_release_version"
    implementation "$corda_group:corda-rpc:$corda_release_version"
    implementation "$springboot_group:spring-boot-starter-web:$springboot_release_version"

    implementation "$newco_group:newco-kotlin-core:$newco_kotlin_core_release_version"
    implementation "$newco_group:newco-kotlin-libex:$newco_libex_release_version"
    implementation "$newco_group:newco-kotlin-libex-services:$newco_libex-services_release_version"
    implementation "$newco_group:newco-corda-fintex-contract:$newco_fintex_release_version"
    implementation "$newco_group:newco-corda-fintex-workflow:$newco_fintex_release_version"
    implementation "$newco_group:newco-corda-fintex-integration:$newco_fintex_release_version"

    implementation project(":cordapp-contract")
    implementation project(":cordapp-workflow")
    implementation project(":cordapp-integration")

    // Test
    testRuntimeOnly "$junit_group:junit-jupiter-engine:$junit_version"
    testImplementation "$junit_group:junit-jupiter-api:$junit_version"
    testImplementation "$kotlin_group:kotlin-test:$kotlin_version"
    testImplementation "$corda_group:corda-node-driver:$corda_release_version"
}

我尝试将其添加到 gradle 但无济于事：

configurations {
    all {
        exclude module: 'slf4j-log4j12'
        exclude module: 'jms'
        exclude module: 'jmxtools'
        exclude module: 'jmxri'
    }
}

有什么想法吗？ - 我不知道从哪里开始

初始化日志接口和实现时似乎存在无限循环，导致 StackOverflowError。

您的类路径上有多个日志绑定，如日志输出所示：

SLF4J：类路径包含多个 SLF4J 绑定。

从您的依赖项中排除 log4j 或 logback 应该可以解决您的问题。

确保您使用正确的排除参考。根据日志输出，我认为您应该排除 log4j-slf4j-impl 而不是 slf4j-log4j12 （或类似的东西）。
