java - Dropwizard 和 hive-jdbc 之间的不兼容

Question

我正在尝试使用 Dropwizard 创建一个 WS REST，以获取查询的 Hive 结果并以 XML 格式呈现。每个单独的部分都可以毫无错误地完成。

当我加入所有内容时，我发现 Dropwizard 和 hive-jdbc 之间不兼容。显然 hive-jdbc 有 jersey 1 作为依赖项，而 Dropwizard 有 jersey 2。

我不确定这是否是问题所在。我试图排除 pom.xml 中的依赖项，但没有解决。

我试图制作一个应用程序，只是将 hive-jdbc 作为依赖项放在 pom.xml 文件中，而不使用或导入代码的任何部分，但错误仍然发生。

    protected final static Logger LOGGER = LoggerFactory.getLogger(TestRes.class);
    protected final static String HEADER = "GroupService::";

    public TestRes(String template, String defaultName) {
        LOGGER.info(HEADER + "init: PostConstruct");
    }

        return "works";
    }
}

我得到的错误是这样的:

我发现一些用户遇到了类似的错误(如 dropwizard and hive/hiverunner integration with maven 和 http://thread.gmane.org/gmane.comp.java.dropwizard.devel/461 )

这是导致错误的问题(在 Jersey 中不兼容)吗？有谁知道怎么解决吗？

Answer 1

是的，它的 jersey 冲突问题，从 hive-jdbc 和 hadoop-core 中排除 jersey 1 依赖项 (com.sun.jersey)。已经运行了您的测试应用程序并且它在以下排除项下工作。

 <dependency>
        <groupId>org.apache.hive</groupId>
        <artifactId>hive-jdbc</artifactId>
        <version>1.1.0</version>
        <exclusions>
            <exclusion>
                <groupId>com.sun.jersey</groupId>
                <artifactId>*</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-core</artifactId>
        <version>1.2.1</version>
        <exclusions>
            <exclusion>
                <groupId>com.sun.jersey</groupId>
