Question

我正在尝试创建一个使用JSON作为输入的休息Web服务。到目前为止，由于我有几个例外，我无法这样做。因为我不是maven用户，所以很难处理依赖项，文档也不是很有帮助。我用作参考的示例是from mkyong website

请有人设法在球衣2中启用json支持吗？任何建议都会非常有帮助，因为我已经走到了尽头。贝娄是我的罐子，也是我的例外。

Answer 1

我很难弄清楚如何配置Jersey 2的依赖项。我使用Maven（推荐），我知道你说你没有使用它，但我可以告诉你我的pom.xml是如何设置的以及mvn dependency:list所说的是我的依赖项（只显示了pom.xml的相关部分））：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.glassfish.jersey</groupId>
            <artifactId>jersey-bom</artifactId>
            <version>${jersey.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

<dependencies>
    <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-servlet-core</artifactId>
    </dependency>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
    </dependency>

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

    <dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-client</artifactId>
    </dependency>
</dependencies>

<!--============================= properties =============================-->
<properties>
    <jersey.version>2.12</jersey.version>
</properties>

这就是Maven所说的我的泽西/杰克逊依赖：
