java - 找不到媒体类型=应用程序/json 的 MessageBodyWriter

Question

我已经尝试了所有方法...无法弄清楚为什么会出现此异常。有趣的是，在我的 IDE (Intellij) 中一切正常。想不通。。。放弃了。

你们有什么建议吗？

    testCompile 'org.spockframework:spock-core:1.0-groovy-2.4'
    testCompile 'cglib:cglib-nodep:2.2'       // For mocking classes
    testCompile 'org.objenesis:objenesis:1.2' // For mocking final classes
    testCompile group: 'junit', name: 'junit', version: '4.9'
}

获取以下内容:

我在 2.22.1 中遇到了同样的错误，我添加了以下依赖项并且它起作用了。

    <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-json-jackson</artifactId>
        <version>2.22.1</version>
    </dependency>
