尝试通过嵌入式Jetty服务器运行Ktor应用程序时如何避免java.lang.ExceptionInInitializerError？

标签： java kotlin jetty ktor

我通过嵌入式Jetty服务器运行我的Ktor网络应用程序。该应用程序在IDE中运行良好。但是，一旦我用shadowJar将其打包并运行生成的胖jar，Jetty服务器就会遇到NoClassDefFoundError。我相信NoClassDefFoundError是由ExceptionInInitializerError引起的，因为在PreEncodedHttpField内部Jetty的静态初始化中存在ArrayIndexOutOfBoundsException。如何在IDE内部不会发生此错误？从胖罐运行Ktor应用程序时如何避免它？

将以下内容添加到Gradle构建脚本中：

import com.github.jengelman.gradle.plugins.shadow.transformers.ServiceFileTransformer
shadowJar {
    transform(ServiceFileTransformer) {
        path = 'META-INF/services'
        include 'org.eclipse.jetty.http.HttpFieldPreEncoder'
    }
}

我最终发现shadowJar不是默认合并我的＆＃34; META-INF＆＃34;文件在一起。这是一个问题，因为当Jetty服务器启动时，它引用＆＃34; META-INF / services / org.eclipse.jetty.http.HttpFieldPreEncoder＆＃34;加载正确的HttpField编码器。由于我的服务文件未正确合并，因此仅加载了Http2编码器。这反过来导致JVM在Jetty试图静态初始化PreEncodedHttpField时抛出java.lang.ExceptionInInitializerError错误，这反过来又导致了Jetty的HttpConnection中的NoClassDefError
