java - 添加 Jersey MOXy 导致 Jetty 运行失败

Question

我正在使用 Jersey、Hibernate 和嵌入式 Jetty 测试 REST。最初，我能够使用./gradlew clean jar && java -jar build/libs/<project>.jar启动一切。 。但是，我想支持 JSON 并从文档中了解到 MOXy 是 Jersey 的默认 JSON 提供程序。所以我在我的 build.gradle 中添加了以下内容文件:

compile 'org.glassfish.jersey.media:jersey-media-moxy:2.19'

之后，我尝试构建 jar 并启动 jetty 但遇到以下问题:

Error: A JNI error has occurred, please check your installation and try again

这是我的 build.gradle如果有帮助的话，请归档。

    }
}

Answer 1

详细了解 gradle 如何构建 fat jar 后，解决问题的方法是修复 jar block :

jar {
    from(configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }) {
        exclude "META-INF/*.SF"
        exclude "META-INF/*.DSA"
        exclude "META-INF/*.RSA"
    }
    manifest {
        attributes 'Main-Class': 'com.domain.scaffolding.Main'
    }
}
