添加 Jersey MOXy 失败 Jetty 运行

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 build.gradle 文件中添加了以下内容：

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

之后，我尝试构建 jar 并启动码头，但出现以下问题：

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

如果有帮助，这是我的 build.gradle 文件。

apply plugin: 'eclipse'
apply plugin: 'java'
apply plugin: 'jetty'

repositories {
    jcenter()
}

dependencies {
    compile 'org.slf4j:slf4j-api:1.7.12'

    // Jetty
    compile 'org.eclipse.jetty:jetty-server:9.3.1.v20150714'
    compile 'org.eclipse.jetty:jetty-servlet:9.3.1.v20150714'

    // Jersey
    compile 'org.glassfish.jersey.containers:jersey-container-servlet:2.19'
    compile 'org.glassfish.jersey.core:jersey-client:2.19'
    compile 'org.glassfish.jersey.media:jersey-media-moxy:2.19'

    compile 'org.glassfish.jersey.media:jersey-media-multipart:2.19'
    compile 'org.glassfish.jersey.media:jersey-media-sse:2.19'

    // Hibernate
    compile 'mysql:mysql-connector-java:5.1.36'
    compile 'org.hibernate:hibernate-core:4.3.10.Final'
    compile 'com.mchange:c3p0:0.9.5.1'

    testCompile 'junit:junit:4.12'
}

jar {
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    manifest {
        attributes 'Main-Class': 'com.domain.scaffolding.Main'
    }
}

Answer 1

在仔细研究了 gradle 如何构建 fat jar 之后，解决问题的方法是修复 jar 块：

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'
    }
}
