Question

我正在尝试使用JAX RS服务。我在我的pom .xml中添加了一些依赖项。这是pom。

    <properties>
    <jersey.version>1.19</jersey.version>
</properties>
<dependencies>
    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-servlet</artifactId>
        <version>${jersey.version}</version>
    </dependency>

    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>${jersey.version}</version>
    </dependency>
    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-client</artifactId>
        <version>${jersey.version}</version>
    </dependency>


    <dependency>
        <groupId>org.mvel</groupId>
        <artifactId>mvel2</artifactId>
        <version>2.2.1.Final</version>
    </dependency>
    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-lang3</artifactId>
        <version>3.0</version>
    </dependency>
    <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
        <version>2.2.4</version>
    </dependency>

    <dependency>
        <groupId>org.apache.drill.exec</groupId>
        <artifactId>drill-jdbc-all</artifactId>
        <version>1.1.0</version>
    </dependency>

</dependencies>

当我添加此依赖项<dependency> <groupId>org.apache.drill.exec</groupId> <artifactId>drill-jdbc-all</artifactId> <version>1.1.0</version> </dependency>时它失败了elow提到的例外。我需要上面提到的apache drill依赖。在移除和运行时，它工作顺利。

我得到的是：

java.lang.NoSuchMethodError: org.codehaus.jackson.map.AnnotationIntrospector.pair(Lorg/codehaus/jackson/map/AnnotationIn
trospector;Lorg/codehaus/jackson/map/AnnotationIntrospector;)Lorg/codehaus/jackson/map/AnnotationIntrospector;

    at com.sun.jersey.server.impl.application.WebApplicationImpl.handleRequest(WebApplicationImpl.java:1419)
    at com.sun.jersey.server.impl.application.WebApplicationImpl.handleRequest(WebApplicationImpl.java:1409)

    at javax.servlet.http.HttpServlet.service(HttpServlet.java:725)
    at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:291).

可以请一些人帮忙，因为在添加特定依赖项时，为什么失败并带有上述异常。

尝试运行mvn依赖树来检查jar中的冲突。

钻包含太多的包，它与app中的其他jar相撞。我也遇到过类似的问题，但是使用了钻头jar的com.google.common.collect和org.apache.zookeeper包。在我的情况下，版本钻取用于这些包较旧，所以，我刚删除它们。

zip -d drill-jdbc-all-1.1.0.jar com/google/common/collect/*
zip -d drill-jdbc-all-1.1.0.jar org/apache/zookeeper/*

现在工作正常。我不知道如何使用maven处理所有这些，因此选择删除。如果maven可以处理它会更好。
